Transcript
- 0:02Yeah, lace them up another way. Another.
- 0:12Easy double, Yeah, from the track to the rodeo, we talk that
- 0:17talk splits on the watch, but we still take the Mick.
- 0:19Dean in Perth with the long run legs going, breaks the fire when
- 0:22the session gets thick. Ryan in the mix with the numbers
- 0:24and plans from everything to medals, Yeah, we break it all
- 0:26down. Hard graft Monday, left about a
- 0:28Sunday still chasing PBS. Hello and welcome back to the
- 0:33Easy Double Podcast. I am very excited this week to
- 0:36be joined for a very interesting chat by Zander Mostert.
- 0:41So Zander is an endurance sports scientist and coach up front
- 0:44runner and his background is he has a Bachelor of Science in
- 0:48Sports Science, Exercise and Health from University of WA.
- 0:53So welcome to the podcast. Zander, how are you doing?
- 0:56Thanks, Ryan. Yeah, I'm good.
- 0:57Thanks. Had my day off today so resting
- 1:01and recovering. Ready to get back to work
- 1:03tomorrow. I'll see you've been doing all
- 1:05your all your research on lactate then freshening up
- 1:08today. Maybe, yeah, renewing the mind,
- 1:11getting them get in the background, all clued up ready
- 1:14for your questions. Yeah, So this conversation
- 1:17comes, the listeners may be familiar on the back of Zander
- 1:22help me do some testing to dial in my zones and my black tape
- 1:26readings as a bit of an experiment the other week.
- 1:29And for us on the podcast, we realised it's a really cool
- 1:33opportunity to kind of deliver a bit of an educational piece as a
- 1:38one off where we usually just talking a bit of rubbish and
- 1:41having banter about running. This will hopefully help unpack
- 1:45some of the myths that sit behind so many of these
- 1:47buzzwords and running right now. LT1LT2 Threshold.
- 1:53So yeah, I'm keen to get into it with you, Xander.
- 1:56But before we do, where? So you've joined.
- 2:01When did you start a front runner?
- 2:03Well, it started officially in Jan, but I've been contracting
- 2:08for a couple months prior. But I wasn't like involved in
- 2:11the community at that point. And now you are fully embedded.
- 2:16Now you're enjoying it, Yeah. Yeah, it's been going well.
- 2:19Lots of learning opportunities, how to like learning how to, to
- 2:26deal with multiple clients. I think before, obviously having
- 2:28a very small group of athletes that I was working with now
- 2:33pretty much tripling, tripling that almost to the to to what I
- 2:37was. It's, it's been a big learning
- 2:40curve how to manage that and, and give everybody the time of
- 2:44day that they deserve. But yeah, it's it's been a good
- 2:47challenge. Tough.
- 2:49I can admit it's been tough, but roughs, roughs good at providing
- 2:53the support you need when you need it and also giving you the
- 2:55space to grow and try things out yourself.
- 2:58Not really like holding you within a box, actually giving
- 3:01you some freedom to experiment and then just helping to make
- 3:05sure that that the results from that experiment are repeatable
- 3:09and trustworthy. So it's been, it's been really
- 3:11good. Can't really ask for a better a
- 3:14better outcome really because coming out of my degree I didn't
- 3:17really have much choice and was very fortunate and blessed to
- 3:20have scored, scored where I am. Yeah.
- 3:23Well, I think did your, your CV kind of spoke for itself, did it
- 3:27in there. Not to undersell you in just
- 3:30being a coach. You also have a pretty strong
- 3:32athlete background yourself in triathlon.
- 3:34And then you had your own kind of like small cohort of clients
- 3:38which are starting to look pretty successful.
- 3:41Yeah, yeah, potentially. I think that's that from memory,
- 3:44that's originally how we got in touch with, with obviously
- 3:49Andrew being a relatively well known runner at the time.
- 3:54But I think, yeah, my background in actual endurance sport is
- 3:58also another thing that sort of separates you from a set of
- 4:03sports science graduates where some people might not really
- 4:05have any, you know, interest in, in endurance.
- 4:08Whereas coming from actually having taken part in some of
- 4:11these events and having the practical knowledge as well
- 4:14definitely helps apply the the theory that you learn in into a
- 4:20program for someone and and understanding their context
- 4:23because you've actually been in the same shoes as well is is
- 4:26pretty good. It definitely helps.
- 4:29Yeah. And would you say your strongest
- 4:31discipline as an athlete is cycling?
- 4:36I'd argue that is true just because I spent most of my time
- 4:41while I was in my peak years of puberty writing.
- 4:45Kind of wish I did stick to running just to see where I
- 4:48would have got, but I'm not sure I I'd say yeah just based off
- 4:53how I responded to the riding I got.
- 4:55I got pretty good, nothing hectic.
- 4:57Definitely enjoyed the riding a lot, but I do kind of wish I did
- 5:01spend a bit more time running as well because I think when I was
- 5:05racing and I did OK, a few good runs here and there wasn't very
- 5:09structured either. I think most of my training I
- 5:12was doing myself as well at that point, but I think I'm, yeah,
- 5:16maybe having a coach would have been cool, a running coach, just
- 5:20to see where that would have got.
- 5:22But I do wish that for myself in the near future as I sort of get
- 5:26over the injury that you're aware of, getting back into the
- 5:29running a little bit more and see where that could potentially
- 5:32take me with the time that I have in my hands.
- 5:36Yeah, well, it is. It is cool to have kind of like
- 5:39a coach who's in the field as well because like particularly
- 5:42on those rides and sessions when I don't want to speak for
- 5:47everyone, but I'm pretty much flat out doing threshold and
- 5:49then you just roll by like you're doing a warm up.
- 5:51It's it's both motivating and depressing at the same time.
- 5:56But then the same would apply if I was to try to run.
- 5:58You know, we both got these sports that we're predisposed
- 6:02to. And for me, it's easy to get
- 6:03back into the to the ride just because I've spent so much time
- 6:06doing it. And then for you, how quickly
- 6:08you've come back into the run versus I have to work so much
- 6:11harder to get a run legs back. So goes both ways.
- 6:15Yeah, OK, fair. And I did come up with a bit of
- 6:19an analogy like Dean's always referring to is, was it CTL
- 6:23cumulative training load and I flipped the L in the T round and
- 6:28we've got Chief lactate technician for you.
- 6:31Would you say that's a a fair representation of what you've
- 6:34been up to recently? Yeah, it feels like it with the
- 6:37number of tests I've been doing. Yeah, I'm sure.
- 6:40Maybe I'll print a little badge out and and put that on my on my
- 6:43shirt at work tomorrow. Yeah, because you'll have to
- 6:48formalise the the knowledge that you adapt in there because how
- 6:52many tests have you done now? It's it's so-called the way that
- 6:55people are able to just kind of like walk in or book online and
- 6:59have access to be able to do this.
- 7:01I actually, so I don't know what you're your background is with
- 7:07the new like all the AI stuff, but it's been great for me in
- 7:10sorting the the tedious tasks of tracking and monitoring.
- 7:14So I got it to do a create a little bit of a spreadsheet with
- 7:18a lot of the OR pretty much all the clients I've had so that I
- 7:21can see when their first Test was and then when the three
- 7:24month date is so I can, in case they haven't booked again, I can
- 7:27just reach out and ask how things are going.
- 7:31But it turns out it's about 41 from when I started already.
- 7:35So that's in like just over three months, 4141 tests, so.
- 7:44Yeah, wow, it's so popular and that's obviously it's helping
- 7:49the individual because they're getting all of their data.
- 7:51But then it also helps you kind of like you're not just then
- 7:55looking at one set of results, you can look at trends and how
- 7:58different people react to it as well.
- 8:01Definitely. And that definitely changes the
- 8:05way you view things because you come into it thinking, oh,
- 8:08everybody's going to fit in the box.
- 8:09And then next thing you know, like your test results, for
- 8:13example, just it doesn't fit the box at all.
- 8:16And you have to you have to figure out what you're doing
- 8:18there and work with it really and look at the context outside
- 8:22of the test. What's the athletes background?
- 8:25How much running have they been doing recently?
- 8:27And used that to almost as a lens to look at the results and
- 8:31that then the results actually make a bit more sense as well.
- 8:35OK, well, let's do try and do a bit of a scene set and some
- 8:39context before we get into the weeds of the test and the
- 8:43results because I'm conscious that lots of the terminology
- 8:47around threshold and lactate can maybe be a bit overwhelming for
- 8:52people. And admittedly, I would have
- 8:55talked about threshold in the past and perhaps not really
- 8:58fully understood what it meant. So I do have a couple of
- 9:02questions. Maybe just your simplest
- 9:06explanation as to what lactate actually is.
- 9:10Yep. Yeah.
- 9:11It's just, it's just a byproduct of glycolysis in its purest
- 9:16form. So glycolysis being the process
- 9:18of splitting glucose for energy in an attempt to produce ATP.
- 9:22So ATP being the the smallest version of energy that we we
- 9:28use. So in almost every movement, any
- 9:31form of metabolism, ATP is being split into ADP in a phosphate to
- 9:38for us to move and do whatever we want to do.
- 9:41But the production of that ATP comes from a few different ways,
- 9:44and glycolysis is one of them. And lactates, yeah, pretty much
- 9:49always being produced in that shuttle.
- 9:52It's just what happens to it when it's produced that that
- 9:57affects, you know, the levels in our bloodstream.
- 10:00So as glucose goes down the chain of glycolysis, it gets to
- 10:05a point where it splits into something called pyruvate.
- 10:10Pyruvate is normally, if the environment is right, shuttled
- 10:14to the mitochondria where it's fully oxidized aerobically, and
- 10:19then you don't have to actually deal with lactate.
- 10:21But sometimes if that pyruvate is being produced faster, then
- 10:26we can shuttle it away. A enzyme called lactate
- 10:31dehydrogenase comes in and converts it into that pyruvate
- 10:35into lactate and now that lactate is there and present.
- 10:39However, I think again, the other thing is just because you
- 10:43have lactate in your bloodstream, the lactate itself
- 10:46is not what's causing the acidosis.
- 10:48It's the hydrogen ions that are paired with it.
- 10:51So we measure, when we measure lactate with a meter, we are
- 10:57invertibly actually measuring the the concentration of
- 11:00hydrogen ions. It's just that luckily for us,
- 11:03the the ratio is 1 to 1. So we know that lactate follows
- 11:10this correlation with exercise intensity and we know that
- 11:13hydrogen ions also follow follow the same correlation.
- 11:16So it's the same pattern. So if we just measure lactate
- 11:19presence, which is much easier than measuring hydrogen ion
- 11:23presence, we can pretty much just get a really good idea of
- 11:27what's going on with the blood pH.
- 11:30And as a result, yeah, we can use that to structure our
- 11:33training zones. And so side note a little bit is
- 11:38bicarb is supposed to. Kind of prevent the negative
- 11:43effects of those hydrogen ions then, not necessarily actually
- 11:46that lactate. Yeah.
- 11:49So the lactate has got the opposite charge of the hydrogen
- 11:53ions and it's actually the same charge as the the bicarbonate
- 11:59from I don't, I have to. I'd have to look into the
- 12:00chemistry, but from memory, you'd have to set it had the
- 12:03same charge as the part of the sodium bicarbonate that bonds to
- 12:07the hydrogen ion to form CO2 and water.
- 12:11So it's it's it's it can't physically.
- 12:14Yeah, bond to the bicarb, the bicarb is what grabs onto the
- 12:20hydrogen ions. So I think the hydrogen ions are
- 12:23H plus. So the lactate would be a minus
- 12:26charge from memory. So yeah, that the, the bicarb is
- 12:30attacking the the hydrogen ions because they're, they're,
- 12:33they're what changed the, the pH in the blood.
- 12:35And then when the pH is off, the muscles can't contract as
- 12:38efficiently as we want them to. And that's when things start
- 12:42falling apart. OK, right.
- 12:45I don't know about chief lactate technician, we might be often to
- 12:48go with the the mad scientist or something here.
- 12:52This is all pretty like, I think from looking back at uni, we
- 12:57learned a little bit about this stuff and I actually went and
- 13:00reviewed some of my notes when the lactate testing started
- 13:04getting pretty serious just to check if I was down on the right
- 13:08track. And it is a little bit
- 13:10unfortunate because it turns out one of my classes, the actual
- 13:15Physiology class, was claiming lactate as a waste product.
- 13:19And that's one of the biggest things that has been sort of
- 13:21kicked to the curb recently. It's not a waste product at all.
- 13:24It's like I said, it's not actually what causes the damage.
- 13:27But when I went and looked at my bioenergetics notes, which is
- 13:32the class where we learn about the more chem chemistry side of
- 13:35things in terms of substrate use and fat breakdown, glucose and
- 13:40all that, that lecture from memory, he was really solid and
- 13:43he he understood it for what it was as a, as a just a byproduct.
- 13:48Yeah, because the body can actually use lactate as fuel in
- 13:52some certain states, can it? Yeah, definitely.
- 13:55So it gets shuttled obviously around the muscle fibers just to
- 13:59get moved around, but then it can also get sent to the heart,
- 14:03the liver, the brain, where it can just be re oxidized.
- 14:06So it goes through the same shuttle where it's converted
- 14:09back into, from memory, pyruvate and then it just goes through
- 14:13that same process of creating ATP.
- 14:16So it's not, it's not at all a waste product.
- 14:20OK. I'm going to continue probably
- 14:22to throw some assumptions at you and you can maybe rubbish them
- 14:25or back them up. So is it true that so when you
- 14:29start exercising in a low intensity state, you are mainly
- 14:34metabolizing fats and therefore you don't produce much lactate,
- 14:39but then as the intensity goes up, your body uses carbohydrates
- 14:44as the primary source of fuel and that is what starts to
- 14:47produce the lactate? Yes.
- 14:50So sort of on the right track. So I think we're always, we
- 14:57always are going through glycolysis.
- 15:00So fat itself doesn't have its own unique metabolic pathway.
- 15:04It's just that we store it as fat.
- 15:06Then that fat gets broken down into a a single fat chain and
- 15:11then that fat chain gets again broken down into glycogen,
- 15:14glucose, it go all goes through the same process.
- 15:17It's just that we as mammals, our bodies want to be efficient.
- 15:23So fat itself stores a lot of energy compared to glucose.
- 15:29So our bodies are more likely to store energy in the form of fat
- 15:34because it doesn't hold on to water and it produces more
- 15:37kilojoules per molecule than glucose or glycogen does.
- 15:41So that's the main reason why we store fat and also because it's
- 15:45got more energy in it. We, our bodies would much rather
- 15:48use that as the fuel source when it comes to low intensity
- 15:52exercise than go down the route of burning glucose and glycogen.
- 15:58The other reason is also because our brain operates of blood
- 16:02glucose. We, we can't just burn it all
- 16:07like exercising because otherwise we leave nothing for
- 16:09our brain. And our brain obviously is one
- 16:10of the, the main consumers of, of, of the glucose and the
- 16:16glycogen in our, in our body. So I think going back to the
- 16:21start, yes, fat is the source of fuel for low intensity exercise,
- 16:28but ultimately it goes down the same process of being getting
- 16:32broken down into going into glycolysis and then through the
- 16:35pyruvate, through Krebs cycle, all of those things.
- 16:38So that that is definitely true. And then because you are always
- 16:44in a state of using glycolysis, there is always going to be a
- 16:48little bit of lactate in your body.
- 16:50So even when you're doing nothing, you still got resting
- 16:53lactate levels and then it's just about how those change
- 16:56depending on your increase in exercise intensity.
- 16:59The other thing that sort of throws a spanner in the works as
- 17:02well, it makes it potentially a little bit more complicated is
- 17:06how muscle fibers, the different types change the fuel substrate
- 17:13use. And when we increase exercise
- 17:16intensity, say from a lower point to a higher point, the
- 17:22slow twitch fibers aren't actually able to to contract
- 17:25fast enough and powerfully enough to fulfill the demand.
- 17:29So now you're suddenly forced to switch to fast twitch fibers.
- 17:33And physiologically fast twitch fibers are not as good as not as
- 17:37good as slow twitch fibers at aerobically breaking down
- 17:41glucose and going through that whole thing.
- 17:43So they end up ultimately producing more lactate.
- 17:46So I think there's two, there's two key players here.
- 17:50There's one, you're creating more lactate then you can
- 17:55lactate again. So Hydra now is 1 to one, but
- 17:58let's just go with lactate. So creating more lactate then
- 18:00you can buffer. And two, the energy demand is
- 18:05too high for your slate rich fibers.
- 18:07So you've got some swap fast, fast rich fibers in play here.
- 18:11And as a result, they are rapidly increasing the
- 18:14production as well. So a few different a few
- 18:17different characters that play in in in why your lactate is
- 18:21actually going up as you increase your intensity.
- 18:24Hence two different athletes athletes being able to have
- 18:28completely different lactate profiles.
- 18:30So you have the on one hand who's full of slow twitch fibres
- 18:35versus the 815 hundred meter guy on the other hand who's jacked
- 18:40up with fast twitch fibres. The LT1 and LT2 could be, let's
- 18:46say, for example, at the same pace, but the actual readings
- 18:50that come out of it are going to be completely different because
- 18:53of the fiber brake makeup. Exactly.
- 18:55Yeah, you'd have one athlete with way more buffering
- 19:00capacity, mitochondrial density so much higher.
- 19:03So like your your sort of test where the readings are just so
- 19:06low and they don't even really want to budget because you've
- 19:10almost got the inability of producing lactate, which is
- 19:14another com complex theory. I guess you could go into and
- 19:18then say the 800m runner who's got so much glycolytic power and
- 19:22his muscle fibers are just ready to just create all this energy.
- 19:27So his lactate levels are going to be a lot higher and also more
- 19:32drastic with how the curve just shoots up.
- 19:34So, and that's something that I've seen with a couple of
- 19:38athletes that have come through recently, sort of had a lot of
- 19:40the juniors tested and the juniors being more orientated to
- 19:44the fastest stuff. I've found that they are way
- 19:47less aerobically efficient than yourself.
- 19:53Like you see the curve is just not very flat at all and it's
- 19:59almost it's almost linear from from the get go as well.
- 20:03So it's interesting. Is it, do you think that's maybe
- 20:06because they haven't like developed much of an aerobic
- 20:09base, but they just because of the muscle fibers that are
- 20:13present, they've got power? Yeah, that, that's definitely
- 20:17it. And I think as we when we get to
- 20:19your test results, you're asking a couple.
- 20:21I saw you're asking a couple of questions about, you know, what
- 20:24it's what it's referring to and what we could start to focus on
- 20:26to increase and get faster. But yeah, aerobic development is
- 20:33definitely important for an athlete racing a aerobic
- 20:36aerobically dominated event. So I'd argue still 1500 plus
- 20:41you're going to see, you know, like Ingerbritsen running 170 KS
- 20:45a week or Kerr Mars up to 150. It's still an aerobic event.
- 20:50So we do want those aerobic traits.
- 20:52But then when we drop down to the 100, absolutely massive
- 20:57shift in Physiology and now suddenly it's all about, you
- 21:00know, can you drop a 22 second 200 meter?
- 21:03Can you sustain this insane speed for, you know, one at one
- 21:08minute, 45 seconds? Like it's a completely different
- 21:10world. And hence the training stimulus
- 21:15and the focus is is completely different.
- 21:19OK. And So what seems to underpin
- 21:21everything is these two titles of LT1 and LT2.
- 21:27So can you kind of try and explain them in how you best
- 21:31understand that? So I recently listened to a
- 21:35podcast from Olive Bird and if you heard of him, he's Christian
- 21:40Blumenfeld's coach. So he's pretty well knowledged
- 21:43on the lactate side of things as well.
- 21:45So that was a great way to learn, but he highlighted this
- 21:49idea that LT1LT1, or lactate threshold 1 only exists because
- 21:56of how we measure. You really only got one point of
- 21:59threshold where there's. I guess if you imagine a seesaw
- 22:04and suddenly it tips over. The only reason we have an LT1
- 22:08is because of how we actually measure blood through a
- 22:14peripheral capillary I guess. So if we were to stab you right
- 22:18in the quad while you're while you're running and test it
- 22:21straight from the muscle body, we would always see more of a
- 22:24linear increase because you can imagine heart rates, linear
- 22:30breathing rates going to be linear or a lot of these fact
- 22:33like cardiac outputs linear with how your exercise is increasing
- 22:38in intensity. So we can almost assume that
- 22:41lactate itself is going to follow the same trajectory.
- 22:44You don't really see why not where the reason why we've got
- 22:48it labeled as LT1 is just because when we are testing, we
- 22:53can, we can, we can plot that point of, OK, it's sort of
- 22:57jumped up now from resting levels and the the buffering
- 23:00time it takes to go from the muscle into the blood stream up
- 23:03to the ER can sometimes hide that pure linear output that we
- 23:09would assume is actually there. So LT1 from the testing point of
- 23:14view and literature represents the first increase above resting
- 23:20levels of your blood lactate. And we would argue that that can
- 23:25also be, you know, terminology wise can also be referred to as
- 23:28your, your tempo. So from there up, you're sort of
- 23:31entering your tempo zone and then LT2 or lactate threshold 2,
- 23:37I guess, really identifies your pure physiological threshold.
- 23:42So if we can imagine that linear line, and then suddenly you get
- 23:45to this point where that that linear pattern just gets thrown
- 23:48out the door. And it's just this exponential
- 23:50jump up where it's unpredictable, representing this
- 23:55chaotic metabolic phase where there's just so much getting
- 23:59produced and our bodies completely unable to buffer it
- 24:02out at the at the same speed. So yeah, pure threshold LT2,
- 24:08LT1, potentially a bit of testing the read like the
- 24:13testing has caused us to to label this sort of first
- 24:16inflection point, but representing this idea of moving
- 24:20away from mainly aerobic contribution now to a little bit
- 24:25more anaerobic contribution as we approach pure Lt. 2.
- 24:30So yeah, again, look, yeah, it's when you when you add more
- 24:35variables into the mix, it can make it a bit more complicated.
- 24:38But as a as a short and sweet statement, LT1 tempo pace Lt. 2
- 24:44pure threshold. So.
- 24:46And so is it fair to say then that LT2 you can be more exact
- 24:50with, whereas LT1 is maybe more of an area or not really?
- 24:55Yeah, definitely you could. You could see it that way.
- 24:57And that's why we like to use queues for a lot of the tempo
- 25:02sessions, getting people to think about how they're feeling
- 25:07and rather than really dictating it too hard with it with an
- 25:12exact pace. But yeah, Lt. 2 is a lot more
- 25:15physiologically identifiable regardless of the athlete.
- 25:20So any, any, any athlete's going to have an LT2 that's very
- 25:25pinpointable and and identifiable.
- 25:28And does the point of equal equilibrium so where production
- 25:33equals clearance levels, does that sit somewhere in between
- 25:37them or? Oh so So production will equal
- 25:43clearance all the way up until Lt. 2.
- 25:45So at LT2 production exceeds maximum clearance capacity.
- 25:50Does that make sense? Yeah.
- 25:51And then anywhere beyond Lt. two, production is just
- 25:54skyrocketing past clearance. Yeah, yeah, exactly.
- 25:59So all the way from resting levels to LT2, our body can
- 26:03match production with clearance. And then past Lt. two production
- 26:11has exceeded maximum clearance. And then this might be a hard
- 26:17question to answer, but how does time in at that intensity
- 26:22influencer? So for example, you might be
- 26:25able to match production with clearance for three minutes, but
- 26:29for 5 minutes, production is more dominant.
- 26:34Or for like if you increase the speed, you might be able to
- 26:40handle it for say like 2 minutes or 90 seconds, but then
- 26:44production exceeds. So is that why we just
- 26:46standardize the test at 3 minutes?
- 26:49Yes. So steady state is something
- 26:52that we try to achieve in these tests.
- 26:54If, if, like you said, if the reps are too short, we're not
- 26:57actually able to get you to a point of meeting the production.
- 27:01So it will take, it does take time for our body to activate
- 27:04these pathways and get everything stabilized.
- 27:07So that's why the reps are normally 3 to 4 minutes.
- 27:10We have moved to a 4 minute test structure now just with lactate
- 27:17strips being a bit harder to source.
- 27:19There's some global outage. So we just need to cut down on
- 27:22on this, on the total steps. But just giving the athlete a
- 27:26few minutes to stabilize, get the heart rate to stabilize,
- 27:29breathing rate to stabilize gives us a better cleaner
- 27:32picture of, of what's actually going on in inside.
- 27:35Yeah. OK.
- 27:37Last question on the LT1LT2 relative to both those reasons,
- 27:43where would marathon pace sit for someone who's well trained?
- 27:48Yeah, that's it. That's a really good question.
- 27:50And I think again, context is so important here.
- 27:54Like the Super elite marathon guys are going to be able to
- 28:00almost sustain, you know, Lt. 2 for that whole 2 hour duration.
- 28:05So that's they've, they've trained so well and they've got
- 28:09in their fat metabolism so strong and their buffering
- 28:13capacity so strong that they would have sit so close to LT2
- 28:16for two hours, where as a recreational runner might be
- 28:22under LT1 even for a marathon, like they'll be that far lower
- 28:27down. And then you could potentially
- 28:29put a you know, relatively fit runner who's say doing 100 KSA
- 28:35week and and going for say sub 3:00 to 2:00 to 2:30.
- 28:40They're probably sitting about halfway and potentially between
- 28:44the two. But again, it's depends on the
- 28:46athletes context. Like what's their muscle fiber
- 28:49makeup? Yes, so many different
- 28:53variables. But I'd say it it could be
- 28:55anywhere from under LT2 for a rec runner, say 4 hours where
- 28:59it's literally just about distance and conditioning, all
- 29:03the way up to just under LT2 for the Super elite where it work,
- 29:10where it's more about the conditioning to sustain maximum
- 29:16clearance and maximum production for two hours in an extent,
- 29:21yeah. So say, let's take someone who's
- 29:24being very deliberate and they're dialed in to lactate and
- 29:27stuff. Are they going to try and
- 29:29develop their Lt. 2 or their threshold as far as they can and
- 29:34then try and work on bridging the gap from LT1 to LT2 to kind
- 29:38of basically push marathon pace faster and faster?
- 29:43It depends where they are originally.
- 29:45So I would argue getting a baseline test where you see OK,
- 29:50what's your goal time for the marathon and where is the LT2
- 29:55sit in relation to that. Now, if your Lt. 2 is like say 5
- 30:00to 10 seconds faster than your gold marathon time, and for most
- 30:03people this is going to be let's let's just say we're talking
- 30:06about a three hour runner that is totally unsustainable.
- 30:11So you're you're going to have to push that way higher up.
- 30:13So I would argue in that person's scenario, the Lt. 2 is
- 30:18a limiting factor and they need to push that up in order to
- 30:21bring LT1 up a bit more so they can sustain that marathon pace
- 30:26at a much lower lactate concentration in their blood.
- 30:30Whereas say someone who's come off doing heaps of 10K work, 5K
- 30:37work, really high levels of top end threshold and say that Lt. 2
- 30:46is sitting quite high in relation to their goal pace.
- 30:50It yeah, it just depends where the LT2 sits in relation and
- 30:54what their goal, what their goal time is.
- 30:56So I think if we plot all those things together, think about
- 31:01conditioning, think about physio Physiology and where that pace
- 31:06puts them on their curve, we can get a bit of an idea of what
- 31:09needs to move in order to make this more achievable for them.
- 31:14Yeah. And that must be hard from a
- 31:17coach's perspective. So you've got someone who is
- 31:20really well developed at like 5 or 10K and they're obviously
- 31:24wanting to improve. And then you start telling them
- 31:27we need to do some low intensity stuff, like we need to slow your
- 31:30sessions right down, increase volume.
- 31:33And obviously you're thinking in the back of your mind, this is
- 31:35to kind of bring that LC one base.
- 31:37So, but the athlete perhaps doesn't see it.
- 31:41So clearly they're just wanting to like push and push and do
- 31:44faster reps. Yeah, yeah, it's creating the
- 31:47foundation for the speed. And I think that's a principle
- 31:52most people are aware of how you go through phases and you can
- 31:54never sustain super high intense training all year round.
- 31:58You have to go through macro cycles and training, training
- 32:02cycles where you build a really good solid foundation, get your
- 32:07aerobic system worked up well, hopefully push that LT1 up as
- 32:11much as we can. And then as you approach your
- 32:13race, you start attacking your threshold, your Lt. 2, and then
- 32:18depending on how old you are as well and what you can handle.
- 32:20But then even looking at VO2 work as well because that that
- 32:23as a last step that drags all three of them as at the same
- 32:27time in a sense, yeah. But just then when you go to
- 32:32VO2, the recovery cost becomes a lot higher.
- 32:36Yeah, all the risks. You just got to factor all the
- 32:38risks and whether you're willing to to give it a go.
- 32:42And again, context matters here. So for a first, I'd say a wreck
- 32:47run, a 3 hour marathoner, I'm never going to get them to do
- 32:50VO2 work because it's unless it's unless they decide they
- 32:53want to come down and race a faster, shorter distance.
- 32:57And we'll bring down the whole, the whole of the weekly volume
- 33:00to reduce fatigue. If, if, if it's training for a
- 33:03marathon for them specifics wise, that's not going to help
- 33:07at all. So yeah.
- 33:10So hypothetically, someone who does VO2 Tuesday, a threshold
- 33:16Thursday, and maybe a session on Saturday, maybe not, versus
- 33:20someone who just does threshold, threshold, threshold.
- 33:23The person who's doing just solely threshold is probably
- 33:27going to get 95% of the gains that the person who does a VO2
- 33:31session is getting anyway, just without the massive 1.
- 33:36I don't know about massive, but all the risk.
- 33:38Yeah, I guess it again, it just depends on the the the race that
- 33:44they're those two athletes to say going for.
- 33:47If we were to plot them out in terms of what distances one
- 33:52would be better at versus the other, I'd argue the obviously
- 33:55the the VO2 guy is going to perform better with the 1500 to
- 33:58say the three K. I'd say they'd be pretty even
- 34:01across 5:00 and 10:00. And then you might find the
- 34:04aerobic the guy doing more threshold work will potentially
- 34:08be a bit better with the half marathon and then maybe the
- 34:12marathon as well. It just, yeah, it just depends
- 34:14on weekly volume and and total exposure and all that sort of
- 34:17stuff. But specificity is, is a super
- 34:22underrated tool for running and knowing how to tweak an
- 34:30athlete's weekly training, but maintain the the core
- 34:33foundations in order to target a specific event and reduce the
- 34:40amount of trusts in their their overall volume.
- 34:43Try to maintain as much consistency as possible.
- 34:46That's always going to result in in a successful event.
- 34:50But completely flipping training around and neglecting some of
- 34:54the core foundational pillars of endurance adaptation is is
- 35:00probably not the best way to go that that's my personal opinion.
- 35:04And I felt I found that that works quite well with with most
- 35:07of my athletes maintaining a really good consistent weekly
- 35:10structure and then tweaking to suit whatever the target is and
- 35:15at the right time that. Makes sense.
- 35:20All right, let's pull it back to the the case study, then the the
- 35:24testing process itself. So I'll speak from my experience
- 35:27as to what we've done with the test, how it was in the front
- 35:32runner lab there in Wembley near Lake Murder, Lake Murders.
- 35:38Yeah, it could be like the number of people that go there.
- 35:45Yeah, so they've, the front runner have got a treadmill set
- 35:48up. Zander has his magical table set
- 35:53up with the gloves, with the with the reader, with the
- 35:56strips. He took my watch off me, which
- 36:00was helpful. So Zan, I had the heart rate
- 36:03monitor on my arm and Zander had my watch on the table.
- 36:06So he was also recording the speed on the treadmill, the
- 36:10heart rate on my watch, the blood lactate reading.
- 36:14And we had this sweat lactate band.
- 36:16But we'll discard that because the reasons didn't do too much.
- 36:22And it was actually useful to take the heart, the rock watch
- 36:25off so that I didn't see my heart rate because you
- 36:27explained. At the.
- 36:28Start. It can act as a bit of noise
- 36:31rarely and negative feedback potentially.
- 36:34Yeah. So the process was I think is
- 36:39the idea 10 by three minute reps well to foot now 4 minutes but.
- 36:43Yeah, now, now obviously changing I guess depending on
- 36:48again the athletes conditioning how long you want to make the
- 36:51test. Ideally you don't want it to be
- 36:52too long because then it's just adds up in terms of fatigue.
- 36:55But for around the 25 to 30 minutes for a test length.
- 37:01And then obviously now being our 4 minutes step, 4 minute step
- 37:03lengths, we're going to about six to seven steps, 4 for each
- 37:07step. And then just increasing the the
- 37:09exercise intensity as we go. It seemed looking for that, for
- 37:13that pattern that we're after. I was thinking walking into the
- 37:17test or I'll probably do some like steady reps after this.
- 37:22There's absolutely no chance in hindsight.
- 37:26Yeah, ref got you to run real hard there at the end.
- 37:28Yeah, there's no strips left because we use them all.
- 37:32Oh yeah, that's true. Yeah.
- 37:34So the idea being that you do your Rep, you start at a pace
- 37:40which is going to be relatively easy.
- 37:42So for us, we started at 13.5 K an hour and after three minutes
- 37:48or 4 minutes at that pace, you jump off the treadmill.
- 37:52Zander's already pierced your ear, which doesn't hurt at all.
- 37:56So the blood, the blood is ready at the surface.
- 38:00You just give it a little squeeze and Zander handles the
- 38:03machine, puts the strip in, gets the reading, all within about 30
- 38:07seconds. And then after 60 or so seconds,
- 38:11we jump back on, bump the pace up and repeat, repeat, repeat
- 38:15until we start seeing some readings that are starting to
- 38:18make sense. Yeah, fair, fair assumption
- 38:21assessments. Yeah, no, definitely.
- 38:24I think with you, we definitely started a bit too slow obviously
- 38:27as you as you've you've come to realize, but a few steps of good
- 38:33aerobic numbers helps with the interpretation.
- 38:38So that's the idea behind that, just to gauge where that first
- 38:41inflection point is and, and what's what's major aerobic for
- 38:45this athlete and then where's the tipping point into some
- 38:48anaerobic work. So that's, that's the goal
- 38:51behind starting relatively slow and also obviously helps as a
- 38:54warm up, getting them used to the, the, the the test process
- 38:58without throwing them straight into like a really hard, hard
- 39:01Rep or anything. So, yeah, now that's that's
- 39:03pretty solid. And we did take a baseline read
- 39:07and before we started, didn't we?
- 39:09And this kind of ties back to what you were speaking about at
- 39:12the start, because the baseline reading was 1.6 and then once
- 39:16we've begun, the readings started from 1.2, which shows
- 39:22that the clearance actually over clears almost what's sitting in
- 39:27your blood just doing nothing. And that's another interesting
- 39:31thing because that's not universally applicable between
- 39:35everyone I've tested. Like some people are testing the
- 39:39same prior as they do after the first Rep, and then some people
- 39:44like yourself are testing higher and then coming down.
- 39:47So could be a testament to your, yeah, I guess your Physiology
- 39:51and showing that you're very aerobically efficient, whereas
- 39:56for others might not just be as developed as you.
- 39:59And that's just sort of the way that they they work.
- 40:04And another interesting idea is one of the athletes I tested a
- 40:08while ago, rec runner, very new to running, hasn't been doing
- 40:13pretty much maybe 20 to 30 days a week for the last few months.
- 40:18Their first readings were upwards of 2 1/2.
- 40:23And that was in an aerobic zone for them because they ran like
- 40:271/2 marathon at this at this pace.
- 40:29So I knew that it was aerobic and I was like, OK, I'm going to
- 40:34ignore that. Although my mind is screaming at
- 40:36me that this is wrong. Like something's missed, we need
- 40:40to cancel. I was like, no, we'll just keep
- 40:42going. And he followed the same trend,
- 40:45just at a higher margin at a higher like starting point,
- 40:49which was quite interesting as well.
- 40:51So. Which rubbishes the assumption
- 40:54that LT1 is always 2 and LT2 is always 3, as in like 2.03 point
- 41:010. Yeah, yeah, that's, that's true.
- 41:04And I do use those markers sometimes when interpreting,
- 41:09depending on the context, because they can they there is
- 41:12evidence from literature that it does apply to the right person,
- 41:17but not as a whole. I tend to stay away from them.
- 41:21Like I'll first look for the pattern again, apply the
- 41:26context, and then if they fit that that picture, then great.
- 41:31If they don't fit that picture, then no, let's let's try
- 41:33different methods. So yeah.
- 41:36And do you think that also says that if anyone is taking lactate
- 41:41readings without understanding their underlying lactate
- 41:44profile, it's almost a waste of time because you could read 2.5
- 41:50and think that it's relatively OK.
- 41:53When we look at like my scores it could be close to LT2 or for
- 41:56someone else it could be LT1 like you just said.
- 42:01Yeah, that's a that's a really good point.
- 42:02I totally agree with you there. Having contextual understanding
- 42:06of your own Physiology is going to allow you to, yeah,
- 42:10accurately do your do your reps like, yeah, like you said, you
- 42:13could be a higher reader and you're doing say tempo and
- 42:17you're reading like 2-6 and you're like, oh, the pros are
- 42:21always at 1.81.9 when they do tempo.
- 42:24I'm I have to slow down when in reality that this is perfectly
- 42:27fine for you. Like you just have to understand
- 42:31why this is different in your context.
- 42:33So yeah, 100%. OK, sweet.
- 42:37Well let's let's go through the results.
- 42:38So we had 13.5 speed, which is 4/30 per K reading of 1.2 and a
- 42:45heart rate of 129. Then we bumped it up 1K an hour
- 42:49for the next two reasons, so 14.5 and 15.5.
- 42:53The lactate millimole stayed at 1.2 for each of them.
- 42:58Heart rate stepped up to 135 and 142 and we got to 16 K an hour
- 43:04which is 1.3 reading and a heart rate of 14816.5 K an hour. 1.3
- 43:11reading heart rate 151 17 K an hour 1.4155 which I remember
- 43:18saying to you before we started, do you remember?
- 43:20My assumption is the LT1 on the heart rate scale sits somewhere
- 43:25in the low one 50s and Lt. 2 was maybe around 170.
- 43:32But the well we can get to the conclusions once we've gone
- 43:35through all the results. 17.5 K an hour, which what pace per
- 43:42kilometre we're up to by that point it's about about. 333
- 43:49yeah. 3:30-ish Yeah, that's fair assumption. 1.4 heart rate of
- 43:5415517.5 K an hour. We stepped up to 1.6 and 160
- 44:00Heart rate 18K an hour. 1.8 Another increase and a heart
- 44:05rate 161 18.5 K an hour. 1.9 reading, 168 heart rate, 19 K an
- 44:14hour. 2.4 reading, so big step up there and 172 heart rate.
- 44:1919.5 K an hour. 2.9 reading, 175 heart rate and the last 120 K an
- 44:26hour reading of 3.7 and a heart rate of 178.
- 44:31With the heart rates, were they the Max heart rate you saw
- 44:34during that period? Yeah.
- 44:38So it's the heart rate at the end of the Rep.
- 44:42Yeah. Like what?
- 44:43What's the live heart rate like at the end of the Rep?
- 44:45Because we're obviously we're gauging your, your, your steady
- 44:49state for each, for each Rep. So we obviously if we take an
- 44:53average and you're really, really good at clearing lactate,
- 44:57you might finish the Rep at 160. And then by the time we start
- 44:59the next one, you're back down to like 110.
- 45:02So if we take the average, it's going to be skewed.
- 45:05So we just take the literally, look at the heart rate in the
- 45:09last 10 seconds and that's what I write down.
- 45:12So, yeah. And so the conclusion we would
- 45:16draw is to summarize the lactate read and stayed below baseline
- 45:22all the way up until it matched baseline at 17.5 K an hour at
- 45:27red 1.6 again after being below it.
- 45:30So that is about 325 per kilometre and corresponding
- 45:35heart rate of 160. So the method that you used, can
- 45:41you explain the different methodologies that you use to
- 45:44draw the conclusion? Yeah, sure.
- 45:46So obviously like I mentioned, there's a few different methods
- 45:51literature wise because it is ultimately a, a function like a
- 45:55math function that we're plotting.
- 45:57So we can rather than like you can eyeball.
- 46:00I think eyeball does work relatively well.
- 46:03But if we want to be a bit more professional and get really
- 46:07precise numbers, then looking at the different methodologies is a
- 46:11good way to do it. So as we mentioned the fixed the
- 46:15fixed concentrations or OBL A, so onset of blood lactate
- 46:19accumulation, those figures do range from 2 to 2.53 to 4.
- 46:26So it just depends if those those actually suit the athlete
- 46:30and their context. There's also baseline relative
- 46:34methods where you're reading a certain number above the
- 46:39baseline. So like it could be .5 or 1.5
- 46:43millimore above baseline. But again, if baseline is high
- 46:48for whatever the reason is, and I have found that that is very
- 46:51consistently so that can massively skew the data.
- 46:56But if someone's baseline is the same as their aerobic levels,
- 47:01then that could work. Like if for them that that that
- 47:04function could work. There's the the standard lactate
- 47:08turn point methods, which is literally just looking for the,
- 47:11the pattern of a flat portion, A slight kick and then a massive
- 47:15kick. So those work really well if
- 47:18someone's got a super, super good profile and their numbers
- 47:23work out that way. And I have, I think those have
- 47:27worked very well in the past. And then for more complicated
- 47:30matters like yours, the D Max, the D Max methods and modified
- 47:35versions of the D Max methods, a good way to to try to denoise
- 47:40and declutter some of the the the numbers on there.
- 47:44That will make it a bit more difficult to use the the other
- 47:47the other forms. So for your LT1, just an A
- 47:52regular D Max method was used. So that's so fitting a a third
- 47:57degree polynomial, which is like almost like a line of best fit,
- 48:00then drawing a straight line from the lowest or first, the
- 48:05first reading to the the last reading and then looking for the
- 48:09furthest point between those two lines.
- 48:12That's going to give us an idea of that first infliction above
- 48:16resting levels where we're no longer sort of in this linear
- 48:20pattern or flat pattern and we're jumping up more than we
- 48:24would expect. And then because of again the
- 48:32the targeting another portion of the curve for Lt. 2, so
- 48:36obviously LT1 we look at the entire curve and then for LT2
- 48:40because we are restricting it to the later portion of the of the
- 48:45results, we can't use the entire curve to to plot that function.
- 48:50We have to cut back some of the results.
- 48:53So the modified D Max uses the same the same function of
- 48:59drawing a line and plotting a line of best fit, but only with
- 49:02the numbers that are .5mm above the What's it here?
- 49:11The I think I wrote it down this is This is way above my pay
- 49:17grade as well. I did not study math, but so
- 49:21modified D Max is rather than anchoring the reference line at
- 49:25the first data point, it anchors it at the data point proceeding
- 49:29the first rise in lactate greater than .4 millimol.
- 49:32So that gets rid of some of the noise and gives us a look at the
- 49:36latest stages of the test. And then again we draw the line
- 49:40polynomial furthest point from that line is going to give us a
- 49:43number. And that's what we would then
- 49:45use to to identify Lt. 2. Yeah.
- 49:50Sweet. So the the highlights is that
- 49:54LT1 was identified at 17.6 K an hour or a reading of 1.6 and Lt.
- 50:012 was identified at 19.5 K an hour or a reading of 3.0.
- 50:09And then you have also expanded that LT1 identifies the
- 50:14intensity at which lactate first begins to deviate meaningfully
- 50:18from a linear response, yet corresponding physiologically to
- 50:22the upper boundary of the purely aerobic training zone.
- 50:26So that makes sense to me, hopefully to others.
- 50:32And the explanation of Lt. 2 was it represents the athletes
- 50:37functional threshold, the highest intensity at which
- 50:40metabolic equilibrium can be maintained.
- 50:42Oh yeah, that was my question from earlier.
- 50:45Yeah, yeah. And serves as the anchor for
- 50:47prescribing threshold and race pace training efforts.
- 50:51How much, how clear can I or how much can I trust the heart rate
- 50:58readings? I know it's purely down to the
- 51:00the device that I'm wearing, but let's say for example, I'm a
- 51:04little bit hesitant that maybe these speeds are a little fast
- 51:10that it's given me. So can I take the heart rate
- 51:13reading at the 1.6 and the 3.0 and replicate that outdoors and
- 51:19use that as the? LC1LC2 yeah, definitely.
- 51:24And I think as you can see obviously in the the training
- 51:28zones table, I haven't given you a specific pace that says, oh,
- 51:32if you don't run this pace, you're not in threshold.
- 51:34Like you have a bit of a window because every day is obviously
- 51:37different. You might have feel bad or slept
- 51:40bad, so your body's going to respond differently.
- 51:43And that's where this idea of triangulating using RPE, heart
- 51:48rate and pace is the best way to ensure you're doing the right
- 51:53thing. So even even the pros doing it
- 51:55and referring back to that podcast I listened to from
- 52:00Christian Bloomfeld's coach, he couldn't stop talking about how
- 52:04regardless of what the media is reading, how many ships they're
- 52:08using, testing after every Rep, he always asks them, how do you
- 52:14feel? Because they know how they feel.
- 52:17And this meter could be reading wrong in that moment.
- 52:20You could have a faulty strip or something else is happening.
- 52:24But if you're hitting pace, your heart rate's working within the
- 52:28window, and you feel the Rep feels the way it should, I'd be
- 52:33pretty confident you're doing the right thing.
- 52:37Yeah, it's, it's so funny, isn't it?
- 52:39With all the tech and science that we have, ultimately
- 52:42everything comes back to fail and all the data just serves as
- 52:46a reference to reinforce it. But the the main summary.
- 52:50That I took away from it is that previously I would have done LT1
- 52:54what I thought was LT1 at maybe like 345.
- 52:58Ish or something but that is based on this.
- 53:01Just a waste of time and way too steady or way too aerobic.
- 53:06Yeah. And it's again you're, you're I
- 53:11guess coming from a place of being a bit more wary with the
- 53:16injury and not really too sure of, of what you're capable of
- 53:21and having something that's going to route you with some
- 53:24numbers. We've got an objective markers
- 53:27here that are telling us that you're pretty fit.
- 53:29Hopefully now you can come, come, come confidently and
- 53:34comfortably, you know, take these numbers and actually apply
- 53:39them in in your training as you go on.
- 53:41And as a result, get continue to get faster rather than just
- 53:45plateau because you're, you know, a bit scared of of pushing
- 53:49the pace and then just holding back because that that
- 53:51ultimately will result in not really much going on.
- 53:53But now that you've got an idea that OK, threshold reps can
- 53:58start to push the pace, you know, bit more same with this
- 54:01with the tempo. And it's not going to be
- 54:03overtraining. In fact, it's going to be the
- 54:05right training. We shouldn't obviously ideally
- 54:09see your your fitness going up. And the other thing as well,
- 54:13which makes me pretty confident that these are right, is your
- 54:16history with, with your running, like your results are a good
- 54:20reflection of these of these paces as well.
- 54:22So again, that's that's another tick.
- 54:24So data looks quick, OK, sure. History.
- 54:30What do you say you ran a 6860? Seven, Yeah. 60 yeah, there you
- 54:35go. Tick lines up pretty well.
- 54:40So yeah, I must admit it has. It has given me more confidence
- 54:43to be a little bit more aggressive with training in the
- 54:48like you hear so much nowadays about like, you know, with the
- 54:51Norwegian method and stuff, everything has to be so
- 54:54controlled and whatever. But yeah.
- 54:57And being wary of overtraining. But this just kind of says I
- 55:01need to stop being a pussy and just get after it a little bit,
- 55:04learn to suffer again. Yeah, that's it.
- 55:08Because it feels uncomfortable, but only for like even since
- 55:12we've done the test, it's been maybe 2 weeks.
- 55:14And then obviously the first time kind of chasing that LT2
- 55:18pace, it's very uncomfortable. But then the more and more you
- 55:20do it, the more comfortable it becomes, and ultimately that's
- 55:25how you lift it up by spending time there.
- 55:28And touching back to what we're talking about before in terms of
- 55:32like maximum time you can spend say at LT1 or LT2 and how the
- 55:37pros are running super close to LT2 for, for even a marathon,
- 55:42there's sort of this rule. Physiologically, you should be
- 55:44able to sustain pure LT2 for like 40 to an hour in terms of
- 55:49time frame. So it's just about, like you
- 55:53said, being OK with the, with the uncomfortability of sitting
- 55:57on that seesaw and not really having massive control over
- 56:02what's going on. And you could tip at one point
- 56:04and then you're done or you might not tip.
- 56:07And then how that increases your conditioning at at that level as
- 56:12well. So like a wreck runner would be
- 56:14able to sustain their pure LT2. I'd, I'd argue literally 30
- 56:18minutes, maybe 4, maybe 40 minutes before for them
- 56:23physically and mentally, it's just too much.
- 56:25But you look at, you know, the, the fastest half marathon
- 56:29runners in the world, they, they can sit on that for an hour,
- 56:33man. And it's, it's insane how, how
- 56:35they're able to do that. It's it's absurd.
- 56:38Yes, it's pretty wild. And that's like reinforces what
- 56:43you've said all along about context mattering so much on on
- 56:48the individual. Yeah, definitely.
- 56:52If if I were to try and take some quick wins from my profile
- 56:56as it is now, would I look to become more?
- 57:01Efficient at LT2 given it feels a little mechanically awkward
- 57:06right now. Maybe mechanically awkward, I'd
- 57:09say physiologically you'd be pretty good at that pace, but we
- 57:14can see that with the results most likely coming from the
- 57:18threshold back work that you've been doing consistently.
- 57:22But I'd say yeah, just mechanic like bio, mechanically getting
- 57:24more comfortable with the gait pattern, it'll take some time.
- 57:29I'd argue though that your LT1 definitely has the ability to
- 57:34get pushed up and I think that's going to come from your mileage
- 57:37slowly increasing. So considering the fact that
- 57:40you're only at what like 100 ish at the moment?
- 57:43Yeah, at the 90 last week, first time.
- 57:46Yeah, you've got a lot, a lot of room to go there.
- 57:48And obviously all that aerobic work is going to make a massive
- 57:51difference in your aerobic efficiency.
- 57:54So you wait till the point when you get to like, you know, the
- 57:57one 50s or one 70s and you're consistently sitting on on this
- 58:02weekly volume where we'd hopefully see that your LT1 is
- 58:06going to start getting pushed up a bit more as well.
- 58:09So yeah, I'm sure RAF. I'm sure RAF got that plan for
- 58:13you. He's just waiting to unleash it
- 58:15at the right time. Oh yeah, yeah, I'll have plenty
- 58:18of things up his sleeve. He was asking me how if I've
- 58:21started thinking about double S again yesterday during like the
- 58:25during the 6th Rep of a threshold set, he was riding
- 58:28alongside me and said when do you want to do double S?
- 58:32Yeah, yeah. I mean.
- 58:34He quickly realized it wasn't the time.
- 58:37You should. You should be able to talk,
- 58:39pretend like you know if you're doing.
- 58:41If you're feeling OK, you should.
- 58:43You should be able to give him a couple of words back.
- 58:45Yeah, maybe it maybe it was a test.
- 58:48Might just be determined to be quiet and leave me alone.
- 58:53I'm conscious of maybe taking a bit more than your time that I
- 58:56said the wood. So just to wrap this up, if
- 58:59people are looking to kind of get their own data, what's the
- 59:03wait list looking like and what's the process to get booked
- 59:06in? It's, it's just strip say like
- 59:10the manufacturer is apparently got a backlog of something and
- 59:17we there's, we can't order ships till June.
- 59:20So I think in terms of how many people I can take in over the
- 59:27next month, might sort of be at capacity, I'm not too sure.
- 59:32It just depends if we can potentially get some more boxes
- 59:35in, in the next few weeks. But it's pretty easy jump onto
- 59:40front runner website and then you can book under the lactate
- 59:44testing like page on on the website and it'll just take you
- 59:48to Clinico and it's selected date that works for you with my
- 59:52availability, availability. And yeah, rock up, bring your
- 59:57high rate monitor, bring your watch water bottle and then
- 1:00:00bring your threshold shoes as well.
- 1:00:03And then we would do like we'd like with you to do a bit of a
- 1:00:06warm up if you don't do it yourself, but normally recommend
- 1:00:09just doing the warm up on the treadmill just to make sure
- 1:00:11we're doing it at the right intensity because some people
- 1:00:13aren't actually sure what what they should be warming up at.
- 1:00:16So 10 minute warm up on the treadmill and then get
- 1:00:20everything set up and then start the test.
- 1:00:23Roughly 30 minutes or so. Sweet and Dean and Owen were
- 1:00:28ripped. Well Owen mainly was ripping me
- 1:00:30for having super shoes on for the for the lactate test.
- 1:00:33But yeah, everyone you you find to wear super shoes.
- 1:00:38Super shoes or far? Or a fast pair of shoes?
- 1:00:41Yeah man. That could also be why you're
- 1:00:45finding the paces a bit quick, like translating them across.
- 1:00:49What shoes do you use for threshold?
- 1:00:52Yeah, I would. Use a plated shoe, to be fair
- 1:00:54the same one that I wore, but maybe the the plate just has an
- 1:00:57extra effect when it's reacting with the treadmill and like that
- 1:01:02surface compared to concrete. Yeah, it is.
- 1:01:06It's the best we can do, man. With the treadmill, like we
- 1:01:08don't really have much other choice.
- 1:01:10No one's really got the capacity to control their intensity to
- 1:01:14that extent outside. It's just not possible.
- 1:01:16So. Dean was also wondering if we
- 1:01:20put the incline on to 1%, he was seeing the numbers and he was
- 1:01:24like Are you sure you had that on an incline?
- 1:01:26It was on 1%. I'm I'm always sure of it.
- 1:01:29So yeah. And lastly then with coaching
- 1:01:34requests, do they go straight through front runner if anyone's
- 1:01:38looking to get coached by you? You can jump on there and send
- 1:01:42in a coach request as well. Send in your goals, your
- 1:01:47history, where do you want to go, what you're doing at the
- 1:01:50moment and then we can organise a bit of a initial meeting so.
- 1:01:55We'll hook you up with the mad scientist or the chief lactate
- 1:01:59technician. There you go.
- 1:02:01That's the new, that's the new, that's the new nickname.
- 1:02:06All right. Thanks so much for your time.
- 1:02:07It's really insightful. I appreciate.
- 1:02:09All your knowledge. No worries, man.
- 1:02:10It was good. Maybe, yeah, maybe again in the
- 1:02:13future, sometime. Sounds good.
- 1:02:15All right. Speak to you soon.
- 1:02:17Cheers, Ryan. Thanks.
- 1:02:18Bye, Miles. In the bank, heart rate low, big
