  Speaker 1: Hey, everybody, welcome to another edition of Wisdom Wednesdays. Today
• 0:12
  Speaker 1: we're going to dive into an intersection of a couple
• 0:16
  Speaker 1: of themes that I've covered before, and those themes are
• 0:20
  Speaker 1: inflammation and exercise, and we're going to be looking at
• 0:25
  Speaker 1: some really interesting new research around resistance training. If you've
• 0:29
  Speaker 1: been following Wisdom Wednesdays, you'll know that I spent twelve
• 0:33
  Speaker 1: weeks exploring the hallmarks of aging. So this is a
• 0:38
  Speaker 1: framework used by scientists the different biological processes that underlie
• 0:44
  Speaker 1: aging and age related diseases. And if you listen to it,
• 0:48
  Speaker 1: you remember that one of the key hallmarks is inflammation,
• 0:52
  Speaker 1: which is often called inflammating or metaflammation because it's basically
• 1:01
  Speaker 1: at of your metabolism and it causes aging. So metaflammation, inflammaging,
• 1:07
  Speaker 1: what if you want to call it, But it's basically chronic,
• 1:10
  Speaker 1: low grade inflammation that tends to increase as we get older.
• 1:15
  Speaker 1: And we know that when you look at pretty much
• 1:18
  Speaker 1: all term diseases, chronic diseases, inflammation is involved in them.
• 1:26
  Speaker 1: So I also mentioned some research a couple of months
• 1:29
  Speaker 1: ago that showed that humans don't age linearly. There seems
• 1:34
  Speaker 1: to be a couple of ages where aging is actually accelerated,
• 1:39
  Speaker 1: and the first one early forties and lots of people
• 1:42
  Speaker 1: will be familiar with that. And then again at around
• 1:47
  Speaker 1: sixty And I was actually talking to somebody recently, a
• 1:50
  Speaker 1: friend of mind, Jeff. He said that he just turned
• 1:52
  Speaker 1: sixty and everything SEMs to be falling off a cliff. Well, actually, Jeff,
• 1:56
  Speaker 1: that is backed up by science. Now, these are periods
• 2:01
  Speaker 1: changes can accelerate, and one of the best tools that
• 2:05
  Speaker 1: we have to offset these is exercise. And both aerobic
• 2:10
  Speaker 1: or cardiovascar exercise and resistance training have got independent and
• 2:16
  Speaker 1: synergistic effects. And I've talked many times before about how
• 2:20
  Speaker 1: it's your cardio respiratory fitness is one of the biggest
• 2:23
  Speaker 1: predictors of how long you're going to live. But another
• 2:26
  Speaker 1: big predictor of how long you're going to live is
• 2:27
  Speaker 1: your muscle strength, particularly in middle age. And this is
• 2:31
  Speaker 1: where today's episode comes in so as a brand new
• 2:34
  Speaker 1: systematic review and meta analysis. So this is where they
• 2:37
  Speaker 1: look at a whole heap of studies, all their data,
• 2:41
  Speaker 1: and they pulled it together and in this one they
• 2:44
  Speaker 1: looked at the impact of resistance training on inflammation as
• 2:49
  Speaker 1: well as body composition and functional capacity in healthy adults
• 2:54
  Speaker 1: who were over the years of sixty, and the findings
• 2:57
  Speaker 1: are pretty compelling for those who have still jump to
• 3:01
  Speaker 1: lift heavy shit. What they did was they analyzed nineteen
• 3:06
  Speaker 1: randomized control trials and together they had seven hundred and
• 3:11
  Speaker 1: twenty eight participants all over the yege of sixty. And
• 3:14
  Speaker 1: what they found was that resistance training significantly reduced levels
• 3:19
  Speaker 1: of C or CRP. You may have seen this on
• 3:23
  Speaker 1: blood tests that you get from the doctor. It is
• 3:26
  Speaker 1: a well known marker of systemic inflammation. And actually you
• 3:31
  Speaker 1: may have heard me talked about when I have my
• 3:33
  Speaker 1: open heart surgery, my sea reactive protein was through the roof,
• 3:38
  Speaker 1: absolutely through the roof, came down quite quickly and not reflected. Actually,
• 3:43
  Speaker 1: how that I felt. Now, reducing sea reactive protein is
• 3:48
  Speaker 1: a big, big win now. They also measured a couple
• 3:51
  Speaker 1: of other inflammatory markers, TNF alpha and interlooking six and
• 3:56
  Speaker 1: the results there were a bit more nuanced significant changes overall,
• 4:02
  Speaker 1: but there were some sex specific differences with reductions noted
• 4:07
  Speaker 1: particularly in females, and interlogun six is an interesting one.
• 4:11
  Speaker 1: T and f Offha is an inflammatory molecule, but interlog
• 4:14
  Speaker 1: in six can be pro inflammatory, but if it's produced
• 4:19
  Speaker 1: from biokine, that's anti inflammatory. So that may be why
• 4:26
  Speaker 1: that was a bit more nuanced, because some of that
• 4:28
  Speaker 1: interlog in six could be the anti inflammatory stuff that's
• 4:32
  Speaker 1: produced from contracting muscle. But anyway, let's get back to this.
• 4:35
  Speaker 1: This is where it gets more interesting. The benefits weren't
• 4:39
  Speaker 1: just limited inflammation, and doing resistance training also led to
• 4:44
  Speaker 1: significant provements in both leg strength and functional capacity, which
• 4:50
  Speaker 1: is really important as we get older because when you
• 4:55
  Speaker 1: start to lose functional capacity, it really then starts to
• 4:59
  Speaker 1: impact upon life. And this is really critical because maintaining
• 5:04
  Speaker 1: that muscle strength and function is one of the best
• 5:07
  Speaker 1: ways to preserve independence and quality of life as we age.
• 5:12
  Speaker 1: And this is not about thinking, hey, I'm too busy
• 5:15
  Speaker 1: because I'm at work and I've got a really busy job.
• 5:18
  Speaker 1: I'll sort this ship retire, as I have heard people say,
• 5:23
  Speaker 1: it becomes a lot harder if you start later. Right now,
• 5:29
  Speaker 1: let's tie all of this in to something that you've
• 5:32
  Speaker 1: heard me go on and on and on about, and
• 5:35
  Speaker 1: that's about mile kinds. These signaling molecules that are released
• 5:39
  Speaker 1: by it during an after exercise, and we know that
• 5:44
  Speaker 1: they have a powerful anti inflammatory effect. Interloking six is
• 5:47
  Speaker 1: one of the anti inflammatory male kinds. But myra kinds
• 5:51
  Speaker 1: overall play a key role in regulating metabolism, and they
• 5:56
  Speaker 1: signal pretty much all of your organs to perform better
• 6:02
  Speaker 1: or to behave better. And when you lift weights, are
• 6:06
  Speaker 1: you doing any type of resistance training and cardiovascular stuff
• 6:09
  Speaker 1: as well. But your muscle is basically acting like an
• 6:13
  Speaker 1: endocrine organ. It's a signaling organ that sends out these
• 6:17
  Speaker 1: mild kinds and they help our systemic inflammation. They also
• 6:23
  Speaker 1: support fat metabolism, and they improve the health of your
• 6:26
  Speaker 1: immune system, your cardio your cardiovascular system. They improve your
• 6:31
  Speaker 1: insulin sensitivity, your bone and blood vessels, and even get
• 6:36
  Speaker 1: into the brain and improve brain function. So instant training
• 6:41
  Speaker 1: is not just about getting big muscles. It's actually about
• 6:45
  Speaker 1: creating a biological environment that helps us to age better.
• 6:50
  Speaker 1: And if you're somebody who doesn't do a lot of
• 6:53
  Speaker 1: this stuff or doesn't do and doesn't know where to start,
• 6:56
  Speaker 1: actually starting with anything. You can use bands, you can
• 6:59
  Speaker 1: use wait stuff, you can use freeways, you can use machines.
• 7:05
  Speaker 1: You don't need to be deadlifting one hundred kilos, but
• 7:07
  Speaker 1: you certainly want to start working towards that and consistency
• 7:13
  Speaker 1: and progression progressive overload, that's really what you're looking at
• 7:19
  Speaker 1: doing here. Worth noting if we go back to this
• 7:22
  Speaker 1: study that the improvements in seriactive protein, that key inflammatory marker,
• 7:28
  Speaker 1: were most pronounced in women, and this suggests that resistance
• 7:33
  Speaker 1: training could be particularly beneficial for postmenopausal women. And if
• 7:39
  Speaker 1: you haven't listened with doctor Stacy Simms, who is the
• 7:43
  Speaker 1: world leader in and particularly around perry and postmenopausal women,
• 7:48
  Speaker 1: she is very very forthright that all postmenopausal women should
• 7:55
  Speaker 1: be lifting heavy shit. And here's another good reason why.
• 8:01
  Speaker 1: It really does seem to have even bigger effects on
• 8:07
  Speaker 1: inflammation and therefore not going to affect to inflammation related
• 8:11
  Speaker 1: diseases for postmenopausal women. So the key takeaway here is
• 8:16
  Speaker 1: that exercise and particularly from this perspective, resus is going
• 8:22
  Speaker 1: to help you not only add years to your life,
• 8:25
  Speaker 1: but add life to your years, right, so that quality
• 8:29
  Speaker 1: of life really is very very key. So go lift
• 8:33
  Speaker 1: some heavy shit. Catch you next time,
