  [Dr. Brent Laartz] Welcome to Sunday Science,
• 0:01
  [Dr. Brent Laartz] where we dive into a few recent scientific articles and their
• 0:04
  [Dr. Brent Laartz] translation into our modern lives.

  [Dr. Brent Laartz] Everyone welcome to Sunday Science again,
• 0:13
  [Dr. Brent Laartz] Episode 5,
• 0:14
  [Dr. Brent Laartz] February 2026.
• 0:16
  [Dr. Brent Laartz] Very apropos topic today,
• 0:20
  [Dr. Brent Laartz] given that this is Super Bowl Sunday.
• 0:23
  [Dr. Brent Laartz] Four articles on longevity in sports.
• 0:25
  [Dr. Brent Laartz] We're going to start out with pro football,
• 0:27
  [Dr. Brent Laartz] talking about the association between playing professional American
• 0:32
  [Dr. Brent Laartz] football and longevity.
• 0:34
  [Dr. Brent Laartz] Thank you.
• 0:34
  [Dr. Brent Laartz] Then we're going to...
• 0:35
  [Dr. Brent Laartz] move on to the Copenhagen City Heart Study.
• 0:39
  [Dr. Brent Laartz] Where basically we show that different sports add years to our lives.
• 0:45
  [Dr. Brent Laartz] And then we're going to talk about elite athletes to determine how
• 0:50
  [Dr. Brent Laartz] they fare with regard to longevity.
• 0:53
  [Dr. Brent Laartz] And then we're going to move to the study everybody's been talking about recently.
• 0:57
  [Dr. Brent Laartz] This year's study basically showing that a variety— of sports is
• 1:04
  [Dr. Brent Laartz] best and potentially that there is some hormesis going on here with
• 1:08
  [Dr. Brent Laartz] regard to sports and maybe too much is not any better than um than a
• 1:14
  [Dr. Brent Laartz] small amount of exercise,
• 1:15
  [Dr. Brent Laartz] however we'll talk about some caveats there okay so starting out uh
• 1:21
  [Dr. Brent Laartz] we're gonna share some some interesting data here.
• 1:24
  [Dr. Brent Laartz] Okay.
• 1:25
  [Dr. Brent Laartz] So let's start out right away.
• 1:35
  [Dr. Brent Laartz] Here as I share the screen,
• 1:37
  [Dr. Brent Laartz] here all right.
• 1:38
  [Dr. Brent Laartz] So this is the pro football uh study.
• 1:44
  [Dr. Brent Laartz] If you can see that over my shoulder,
• 1:47
  [Dr. Brent Laartz] there is uh some of the study here showing.
• 1:50
  [Dr. Brent Laartz] If you look on the left,
• 1:52
  [Dr. Brent Laartz] and if you're not showing a video.
• 1:55
  [Dr. Brent Laartz] If you are listening to this on a podcast,
• 1:58
  [Dr. Brent Laartz] let me tell you that the graph we're looking at is the probability of death.
• 2:03
  [Dr. Brent Laartz] And if you look at the full national health survey,
• 2:08
  [Dr. Brent Laartz] that the probability of death is approximately 0.
• 2:13
  [Dr. Brent Laartz] 05 per person years and all football players come in lower than that.
• 2:22
  [Dr. Brent Laartz] Which could be expected.
• 2:23
  [Dr. Brent Laartz] They are athletes,
• 2:24
  [Dr. Brent Laartz] right?
• 2:24
  [Dr. Brent Laartz] However,
• 2:25
  [Dr. Brent Laartz] if you subtract out and do a restricted sample of the National
• 2:30
  [Dr. Brent Laartz] Health Survey and take those people who are younger and employed,
• 2:36
  [Dr. Brent Laartz] which are football players,
• 2:38
  [Dr. Brent Laartz] are,
• 2:39
  [Dr. Brent Laartz] and a few other different demographics.
• 2:42
  [Dr. Brent Laartz] And if you restrict that sample,
• 2:44
  [Dr. Brent Laartz] it becomes approximately the same as all football players.
• 2:48
  [Dr. Brent Laartz] If you do then also in the middle of the study there,
• 2:53
  [Dr. Brent Laartz] taking out football linemen,
• 2:55
  [Dr. Brent Laartz] those people Those football players do approximately the same as far
• 3:01
  [Dr. Brent Laartz] as their probability of death as the full NHIS sample.
• 3:07
  [Dr. Brent Laartz] But that,
• 3:07
  [Dr. Brent Laartz] again,
• 3:08
  [Dr. Brent Laartz] is not age matched.
• 3:09
  [Dr. Brent Laartz] Those are all comers.
• 3:11
  [Dr. Brent Laartz] Those are.
• 3:11
  [Dr. Brent Laartz] not in the same socio-demographic region here.
• 3:17
  [Dr. Brent Laartz] But all other football players still retain,
• 3:21
  [Dr. Brent Laartz] in other words,
• 3:22
  [Dr. Brent Laartz] other positional players,
• 3:23
  [Dr. Brent Laartz] people who are potentially less obese,
• 3:28
  [Dr. Brent Laartz] maybe lower size,
• 3:30
  [Dr. Brent Laartz] less likely to have injuries.
• 3:36
  [Dr. Brent Laartz] Take all other football players they still match to those age,
• 3:40
  [Dr. Brent Laartz] risk,
• 3:41
  [Dr. Brent Laartz] and social demographic status players,
• 3:45
  [Dr. Brent Laartz] so and if we move on to the next,
• 3:49
  [Dr. Brent Laartz] it's basically pretty much similar where we tease out The different.
• 3:54
  [Dr. Brent Laartz] Players.
• 3:56
  [Dr. Brent Laartz] Based on position,
• 3:57
  [Dr. Brent Laartz] either lineman or non-lineman.
• 3:59
  [Dr. Brent Laartz] And again,
• 4:00
  [Dr. Brent Laartz] it plays out that the linemen do much worse than the rest,
• 4:04
  [Dr. Brent Laartz] okay?
• 4:05
  [Dr. Brent Laartz] So here,
• 4:07
  [Dr. Brent Laartz] this graph...
• 4:09
  [Dr. Brent Laartz] shows,
• 4:10
  [Dr. Brent Laartz] and here they teased out.
• 4:13
  [Dr. Brent Laartz] People.
• 4:14
  [Dr. Brent Laartz] and players.
• 4:15
  [Dr. Brent Laartz] who had been drafted.
• 4:17
  [Dr. Brent Laartz] but they never played a professional game.
• 4:20
  [Dr. Brent Laartz] versus a player who is drafted and played at least one professional game.
• 4:26
  [Dr. Brent Laartz] So here's the same size of a player.
• 4:28
  [Dr. Brent Laartz] If they're on the left,
• 4:30
  [Dr. Brent Laartz] it's the offensive and defensive lineman and other professional.
• 4:34
  [Dr. Brent Laartz] players or other position players on the right on the left the
• 4:38
  [Dr. Brent Laartz] offensive and defensive linemen if they did not have A single professional game.
• 4:47
  [Dr. Brent Laartz] they actually lived two years longer than the person who played at
• 4:53
  [Dr. Brent Laartz] least one professional game.
• 4:56
  [Dr. Brent Laartz] Hence,
• 4:56
  [Dr. Brent Laartz] why would that be if they played one professional game?
• 4:59
  [Dr. Brent Laartz] but they were both drafted.
• 5:01
  [Dr. Brent Laartz] You would think they'd be the same size and they'd still be
• 5:04
  [Dr. Brent Laartz] potentially trying to um maintain the same physical stamina,
• 5:11
  [Dr. Brent Laartz] et cetera,
• 5:11
  [Dr. Brent Laartz] throughout a career that they were trying to get into and play a professional game.
• 5:17
  [Dr. Brent Laartz] So potentially it's...
• 5:20
  [Dr. Brent Laartz] thinking and the teasing out here is potentially that injury might be the reason,
• 5:26
  [Dr. Brent Laartz] but and then on the other side,
• 5:29
  [Dr. Brent Laartz] the same status of having never played a professional game does not
• 5:34
  [Dr. Brent Laartz] gain any additional years of life than someone who played in at
• 5:41
  [Dr. Brent Laartz] least one professional game— it's 59.
• 5:43
  [Dr. Brent Laartz] 1 versus 59.
• 5:45
  [Dr. Brent Laartz] 2 years of age,
• 5:48
  [Dr. Brent Laartz] so now,
• 5:50
  [Dr. Brent Laartz] years of age,
• 5:51
  [Dr. Brent Laartz] probability percent surviving,
• 5:53
  [Dr. Brent Laartz] as an average.
• 5:54
  [Dr. Brent Laartz] Okay,
• 5:55
  [Dr. Brent Laartz] so um.
• 6:00
  [Dr. Brent Laartz] So certainly now we can see.
• 6:03
  [Dr. Brent Laartz] that some of the data where we have seen that professional football
• 6:08
  [Dr. Brent Laartz] players and elite athletes.
• 6:11
  [Dr. Brent Laartz] Potentially live longer,
• 6:12
  [Dr. Brent Laartz] but there is a caveat to that,
• 6:14
  [Dr. Brent Laartz] okay?
• 6:15
  [Dr. Brent Laartz] And there are certainly a lot more studies that need to be done.
• 6:22
  [Dr. Brent Laartz] Copenhagen City Heart Study was a study in Copenhagen,
• 6:27
  [Dr. Brent Laartz] Denmark,
• 6:28
  [Dr. Brent Laartz] and this Danish study wanted to tease out different sports that
• 6:33
  [Dr. Brent Laartz] people played recreationally.
• 6:36
  [Dr. Brent Laartz] Either team sports or racket sports or solo sports.
• 6:40
  [Dr. Brent Laartz] And whether they added extra years of life.
• 6:43
  [Dr. Brent Laartz] And the main takeaway here is the bottom bar graph on the bottom right.
• 6:50
  [Dr. Brent Laartz] You can see that,
• 6:52
  [Dr. Brent Laartz] adjusted for age,
• 6:54
  [Dr. Brent Laartz] sex,
• 6:55
  [Dr. Brent Laartz] weekly volume,
• 6:56
  [Dr. Brent Laartz] smoking,
• 6:57
  [Dr. Brent Laartz] education,
• 6:57
  [Dr. Brent Laartz] drinking habits,
• 6:58
  [Dr. Brent Laartz] et cetera,
• 6:59
  [Dr. Brent Laartz] tennis.
• 7:01
  [Dr. Brent Laartz] And badminton had a much higher level of added years of life than other sports.
• 7:09
  [Dr. Brent Laartz] So you can see,
• 7:10
  [Dr. Brent Laartz] let's go.
• 7:10
  [Dr. Brent Laartz] Start from the top at sedentary.
• 7:13
  [Dr. Brent Laartz] These are the reference.
• 7:14
  [Dr. Brent Laartz] So the hazard ratio of mortality is 1.
• 7:19
  [Dr. Brent Laartz] 00.
• 7:20
  [Dr. Brent Laartz] They are the reference and you can see that health club activities added,
• 7:26
  [Dr. Brent Laartz] on average,
• 7:26
  [Dr. Brent Laartz] 1.
• 7:27
  [Dr. Brent Laartz] 5 years of age and that crosses the zero the 1.
• 7:33
  [Dr. Brent Laartz] 0 hazard ratio line,
• 7:35
  [Dr. Brent Laartz] so it probably is not significant.
• 7:37
  [Dr. Brent Laartz] So just plain working out and doing health club activities is not a
• 7:41
  [Dr. Brent Laartz] significant improvement.
• 7:44
  [Dr. Brent Laartz] Swimming and calisthenics and cycling had approximately similar numbers,
• 7:51
  [Dr. Brent Laartz] around 3 to 3.
• 7:52
  [Dr. Brent Laartz] 7.
• 7:54
  [Dr. Brent Laartz] Jogging added 3.
• 7:56
  [Dr. Brent Laartz] 2 years and their hazard ratio was significantly below the 1.
• 8:01
  [Dr. Brent Laartz] 0 then you had soccer,
• 8:05
  [Dr. Brent Laartz] which was a league above and potentially this—um— we'll talk about this in a minute,
• 8:10
  [Dr. Brent Laartz] as to why that is a league above at 4.
• 8:12
  [Dr. Brent Laartz] 7 years and then above that,
• 8:15
  [Dr. Brent Laartz] badminton and tennis,
• 8:17
  [Dr. Brent Laartz] 6.
• 8:18
  [Dr. Brent Laartz] 2 and 9.
• 8:19
  [Dr. Brent Laartz] 7 years,
• 8:19
  [Dr. Brent Laartz] additive age.
• 8:20
  [Dr. Brent Laartz] So interesting to see this study.
• 8:23
  [Dr. Brent Laartz] This was back in 2018,
• 8:25
  [Dr. Brent Laartz] this would suggest that—um— that maybe racket sports were better and
• 8:32
  [Dr. Brent Laartz] team sports were better than solo sports such as swimming,
• 8:36
  [Dr. Brent Laartz] calisthenics,
• 8:37
  [Dr. Brent Laartz] cycling,
• 8:37
  [Dr. Brent Laartz] and jogging,
• 8:38
  [Dr. Brent Laartz] and all of them were better than health club activities,
• 8:41
  [Dr. Brent Laartz] which,
• 8:42
  [Dr. Brent Laartz] who knows what,
• 8:42
  [Dr. Brent Laartz] health club activities,
• 8:44
  [Dr. Brent Laartz] different people.
• 8:46
  [Dr. Brent Laartz] Could take that as a different status.
• 8:48
  [Dr. Brent Laartz] The health club in Denmark could have been something where they were
• 8:53
  [Dr. Brent Laartz] going and walking for a small amount of time.
• 8:59
  [Dr. Brent Laartz] or maybe even just socializing and not even exercising.
• 9:03
  [Dr. Brent Laartz] Anyway,
• 9:03
  [Dr. Brent Laartz] that's...
• 9:04
  [Dr. Brent Laartz] A little bit facetious there,
• 9:06
  [Dr. Brent Laartz] but interesting study nonetheless back in 2018.
• 9:11
  [Dr. Brent Laartz] Next,
• 9:12
  [Dr. Brent Laartz] we're going to turn our eyes to the elite athletes.
• 9:17
  [Dr. Brent Laartz] This would then take this to another level,
• 9:19
  [Dr. Brent Laartz] right?
• 9:19
  [Dr. Brent Laartz] So an elite athlete is going to take that to another level.
• 9:23
  [Dr. Brent Laartz] This is not just recreational.
• 9:25
  [Dr. Brent Laartz] These have been shown in multiple studies to have improved.
• 9:30
  [Dr. Brent Laartz] mortality,
• 9:31
  [Dr. Brent Laartz] in elite athletes.
• 9:33
  [Dr. Brent Laartz] However,
• 9:34
  [Dr. Brent Laartz] There is some caveat to here.
• 9:35
  [Dr. Brent Laartz] Again,
• 9:36
  [Dr. Brent Laartz] Not every sport is deemed equal,
• 9:39
  [Dr. Brent Laartz] just like we talked about football.
• 9:41
  [Dr. Brent Laartz] Than not every lineman versus a,
• 9:44
  [Dr. Brent Laartz] for example,
• 9:44
  [Dr. Brent Laartz] a quarterback or a running back who are in much better shape.
• 9:49
  [Dr. Brent Laartz] Potentially more cardiovascular versus only strength training.
• 9:54
  [Dr. Brent Laartz] And here,
• 9:56
  [Dr. Brent Laartz] this was in the British Journal of Sports Medicine back in 2015.
• 10:01
  [Dr. Brent Laartz] You can see that endurance sports,
• 10:05
  [Dr. Brent Laartz] which they took in.
• 10:08
  [Dr. Brent Laartz] Finland.
• 10:09
  [Dr. Brent Laartz] So these are Finnish people.
• 10:11
  [Dr. Brent Laartz] This was a control study.
• 10:15
  [Dr. Brent Laartz] The control was on the left line there.
• 10:17
  [Dr. Brent Laartz] You can see this hashed line on the left,
• 10:20
  [Dr. Brent Laartz] maybe what we call a dotted line.
• 10:22
  [Dr. Brent Laartz] I'm not sure how you call that a dotted line,
• 10:24
  [Dr. Brent Laartz] but that's what it was.
• 10:26
  [Dr. Brent Laartz] That control had a certain proportion surviving over the course of 100 years,
• 10:31
  [Dr. Brent Laartz] and that curve you can see.
• 10:35
  [Dr. Brent Laartz] And you can see there are three other curves there.
• 10:37
  [Dr. Brent Laartz] And the best curve,
• 10:38
  [Dr. Brent Laartz] the furthest off to the right,
• 10:40
  [Dr. Brent Laartz] is the dash,
• 10:41
  [Dr. Brent Laartz] is the solid line.
• 10:44
  [Dr. Brent Laartz] And that,
• 10:45
  [Dr. Brent Laartz] compared to the control,
• 10:48
  [Dr. Brent Laartz] has a hazard ratio of 0.
• 10:50
  [Dr. Brent Laartz] 62.
• 10:51
  [Dr. Brent Laartz] 38% less likely of dying at any particular age on average.
• 10:56
  [Dr. Brent Laartz] And then there's another line there that's very close to the team.
• 11:02
  [Dr. Brent Laartz] Close to that endurance line,
• 11:05
  [Dr. Brent Laartz] endurance sports let me get to you exactly what sports we're talking about here.
• 11:11
  [Dr. Brent Laartz] Because in Finland,
• 11:12
  [Dr. Brent Laartz] it's not all the same sports as we have in the United States of America.
• 11:16
  [Dr. Brent Laartz] But cross-country skiing,
• 11:18
  [Dr. Brent Laartz] middle-distance runner,
• 11:20
  [Dr. Brent Laartz] and long-distance running— so those endurance sports.
• 11:23
  [Dr. Brent Laartz] Despite what we talked about earlier with the recreational jogging
• 11:27
  [Dr. Brent Laartz] being middle of the line,
• 11:28
  [Dr. Brent Laartz] this is actually the higher of the line.
• 11:30
  [Dr. Brent Laartz] These are people who were...
• 11:32
  [Dr. Brent Laartz] very cardiovascularly fit.
• 11:35
  [Dr. Brent Laartz] And probably not a lot of strength training.
• 11:37
  [Dr. Brent Laartz] Obviously,
• 11:37
  [Dr. Brent Laartz] some elite,
• 11:39
  [Dr. Brent Laartz] all elite athletes in cross country skiing,
• 11:42
  [Dr. Brent Laartz] running,
• 11:43
  [Dr. Brent Laartz] also have some strength training.
• 11:46
  [Dr. Brent Laartz] But,
• 11:46
  [Dr. Brent Laartz] then you have the team sports,
• 11:48
  [Dr. Brent Laartz] which is next,
• 11:49
  [Dr. Brent Laartz] has a hazard ratio of 0.
• 11:51
  [Dr. Brent Laartz] 71,
• 11:51
  [Dr. Brent Laartz] so about 29% less likely of dying than the control sedentary person
• 11:57
  [Dr. Brent Laartz] who is not an elite athlete.
• 12:01
  [Dr. Brent Laartz] So then,
• 12:02
  [Dr. Brent Laartz] and this defined as soccer,
• 12:06
  [Dr. Brent Laartz] basketball,
• 12:07
  [Dr. Brent Laartz] ice hockey,
• 12:08
  [Dr. Brent Laartz] jumpers,
• 12:09
  [Dr. Brent Laartz] short distance runners,
• 12:10
  [Dr. Brent Laartz] and hurdlers.
• 12:12
  [Dr. Brent Laartz] Okay,
• 12:12
  [Dr. Brent Laartz] so...
• 12:13
  [Dr. Brent Laartz] then you can see it line there that is a bit closer just to the
• 12:18
  [Dr. Brent Laartz] right of the control line.
• 12:21
  [Dr. Brent Laartz] Power sports,
• 12:22
  [Dr. Brent Laartz] and these who are boxing,
• 12:23
  [Dr. Brent Laartz] wrestling,
• 12:24
  [Dr. Brent Laartz] weightlifting,
• 12:24
  [Dr. Brent Laartz] and throwing sports.
• 12:26
  [Dr. Brent Laartz] These are much more likely to be larger individuals,
• 12:29
  [Dr. Brent Laartz] and they are much more more likely to have injuries,
• 12:32
  [Dr. Brent Laartz] maybe potentially traumatic brain injuries,
• 12:36
  [Dr. Brent Laartz] but also they may use performance-enhancing medications.
• 12:42
  [Dr. Brent Laartz] You know,
• 12:43
  [Dr. Brent Laartz] I think that potentially.
• 12:44
  [Dr. Brent Laartz] And some of these other sports could also,
• 12:47
  [Dr. Brent Laartz] but these might be a little bit more likely to.
• 12:49
  [Dr. Brent Laartz] Throwing sports,
• 12:50
  [Dr. Brent Laartz] those such as discus and shot put and javelin.
• 12:54
  [Dr. Brent Laartz] May have more likely to have more obese,
• 12:59
  [Dr. Brent Laartz] larger frames,
• 13:02
  [Dr. Brent Laartz] et cetera.
• 13:02
  [Dr. Brent Laartz] That has a ratio is only 0.
• 13:05
  [Dr. Brent Laartz] 85 and um and some of these studies have shown that there is not a
• 13:11
  [Dr. Brent Laartz] statistical significant difference between that and the control.
• 13:15
  [Dr. Brent Laartz] So again,
• 13:16
  [Dr. Brent Laartz] here,
• 13:16
  [Dr. Brent Laartz] interesting to see that these um again endurance sports are better
• 13:22
  [Dr. Brent Laartz] team sports where you may have some strength training also,
• 13:27
  [Dr. Brent Laartz] but also certainly some cardiovascular,
• 13:33
  [Dr. Brent Laartz] fitness as well.
• 13:34
  [Dr. Brent Laartz] But the power,
• 13:35
  [Dr. Brent Laartz] which is strictly strength and less cardiovascular exercise,
• 13:40
  [Dr. Brent Laartz] is closer to the control.
• 13:43
  [Dr. Brent Laartz] Okay,
• 13:43
  [Dr. Brent Laartz] so next.
• 13:46
  [Dr. Brent Laartz] Let's move on to the study in British Medical Journal Medicine,
• 13:50
  [Dr. Brent Laartz] 2026.
• 13:51
  [Dr. Brent Laartz] This is the study everybody's been talking about.
• 13:54
  [Dr. Brent Laartz] And this is the total physical activity.
• 13:59
  [Dr. Brent Laartz] This study's physical activity types,
• 14:01
  [Dr. Brent Laartz] variety,
• 14:01
  [Dr. Brent Laartz] and mortality results from two prospective cohort studies.
• 14:05
  [Dr. Brent Laartz] So this study took different types of exercise.
• 14:08
  [Dr. Brent Laartz] And this is total physical activity.
• 14:11
  [Dr. Brent Laartz] So this graph here is basically taking any physical activity and
• 14:15
  [Dr. Brent Laartz] seeing what the mortality is.
• 14:16
  [Dr. Brent Laartz] And I'll cause mortality in the blue line there.
• 14:19
  [Dr. Brent Laartz] With these persons who had X amount of physical activity.
• 14:23
  [Dr. Brent Laartz] And these are met hours per week.
• 14:25
  [Dr. Brent Laartz] So probably around 20 to 40 met hours per week is going to be
• 14:30
  [Dr. Brent Laartz] running three to four times a day,
• 14:33
  [Dr. Brent Laartz] something like that.
• 14:34
  [Dr. Brent Laartz] And so,
• 14:35
  [Dr. Brent Laartz] as you move out this line here at a certain number at 20 met hours per week,
• 14:44
  [Dr. Brent Laartz] you have the line coming down from 1.
• 14:48
  [Dr. Brent Laartz] 00 hazard ratio down to about 0.
• 14:52
  [Dr. Brent Laartz] 75 for all-cause mortality,
• 14:54
  [Dr. Brent Laartz] and that points— maybe 0.
• 14:56
  [Dr. Brent Laartz] 7.
• 14:57
  [Dr. Brent Laartz] And so,
• 14:58
  [Dr. Brent Laartz] about a 30% decreased risk of dying.
• 15:02
  [Dr. Brent Laartz] But it plateaus and goes off onto up to 100 met hours per week.
• 15:08
  [Dr. Brent Laartz] Which could be potentially running,
• 15:10
  [Dr. Brent Laartz] you know,
• 15:12
  [Dr. Brent Laartz] an hour,
• 15:12
  [Dr. Brent Laartz] seven days a week,
• 15:14
  [Dr. Brent Laartz] something along those lines.
• 15:16
  [Dr. Brent Laartz] That shows that running or walking.
• 15:21
  [Dr. Brent Laartz] Two to three days a week is the same as 100.
• 15:25
  [Dr. Brent Laartz] Met hours per week and that's seven days a week running right.
• 15:28
  [Dr. Brent Laartz] So the much higher level of exercise is not necessarily any better.
• 15:32
  [Dr. Brent Laartz] And this is borne out with respiratory disease.
• 15:36
  [Dr. Brent Laartz] The likelihood of dying of a respiratory disease,
• 15:39
  [Dr. Brent Laartz] cancer,
• 15:40
  [Dr. Brent Laartz] cardiovascular disease,
• 15:41
  [Dr. Brent Laartz] or other causes actually tends to increase as you head out to and
• 15:48
  [Dr. Brent Laartz] that's in that yellow,
• 15:51
  [Dr. Brent Laartz] more of an orangish line that increases beyond the pink cancer line there.
• 15:56
  [Dr. Brent Laartz] And it comes back up to like 0.
• 15:59
  [Dr. Brent Laartz] 9 there.
• 16:00
  [Dr. Brent Laartz] As you get to a higher physical activity.
• 16:02
  [Dr. Brent Laartz] And I'm not sure how this is explained,
• 16:05
  [Dr. Brent Laartz] whether this is explained by bicycling and potentially getting hit by a bus,
• 16:11
  [Dr. Brent Laartz] perhaps,
• 16:11
  [Dr. Brent Laartz] or something along those lines.
• 16:13
  [Dr. Brent Laartz] I don't know.
• 16:13
  [Dr. Brent Laartz] This certainly,
• 16:14
  [Dr. Brent Laartz] other causes,
• 16:15
  [Dr. Brent Laartz] is a nebulous portion here.
• 16:21
  [Dr. Brent Laartz] This next part teases out.
• 16:24
  [Dr. Brent Laartz] Uh,
• 16:24
  [Dr. Brent Laartz] the different types of exercise.
• 16:26
  [Dr. Brent Laartz] Um,
• 16:27
  [Dr. Brent Laartz] and essentially,
• 16:29
  [Dr. Brent Laartz] here's showing that walking potentially is the best here.
• 16:32
  [Dr. Brent Laartz] Um,
• 16:33
  [Dr. Brent Laartz] and especially while walking is the best.
• 16:35
  [Dr. Brent Laartz] At individual physical activities,
• 16:38
  [Dr. Brent Laartz] it decreases down to around 0.
• 16:41
  [Dr. Brent Laartz] 75.
• 16:42
  [Dr. Brent Laartz] So,
• 16:42
  [Dr. Brent Laartz] about 25% decrease just with five met hours per week.
• 16:47
  [Dr. Brent Laartz] I can tell you that a couple of things are at play here.
• 16:53
  [Dr. Brent Laartz] But again,
• 16:54
  [Dr. Brent Laartz] it plateaus going all the way out to 40 met hours per week.
• 16:58
  [Dr. Brent Laartz] No benefit from 5 to 40 met hours per week.
• 17:02
  [Dr. Brent Laartz] In the,
• 17:02
  [Dr. Brent Laartz] let's go to the yellow line,
• 17:04
  [Dr. Brent Laartz] we've got jogging.
• 17:05
  [Dr. Brent Laartz] Comes down to about 0.
• 17:07
  [Dr. Brent Laartz] 85.
• 17:08
  [Dr. Brent Laartz] As you get to the five-minute hours per week,
• 17:10
  [Dr. Brent Laartz] but as you start getting up to 15,
• 17:12
  [Dr. Brent Laartz] it's a U-shaped curve.
• 17:15
  [Dr. Brent Laartz] So it improves,
• 17:17
  [Dr. Brent Laartz] but then it starts heading back up toward a 1.
• 17:21
  [Dr. Brent Laartz] 00.
• 17:22
  [Dr. Brent Laartz] Similar lines are for running,
• 17:25
  [Dr. Brent Laartz] but this is more of a W-shaped curve.
• 17:30
  [Dr. Brent Laartz] Where you have decrease in mortality,
• 17:37
  [Dr. Brent Laartz] then a slight increase,
• 17:39
  [Dr. Brent Laartz] and then further decrease from there.
• 17:42
  [Dr. Brent Laartz] Again,
• 17:43
  [Dr. Brent Laartz] some element of something called hormesis,
• 17:45
  [Dr. Brent Laartz] and what is hormesis?
• 17:47
  [Dr. Brent Laartz] Hormesis suggests that there is a middle ground that is the best.
• 17:53
  [Dr. Brent Laartz] You want to have some stress,
• 17:56
  [Dr. Brent Laartz] but you don't want to have too much stress because some stress is good for you.
• 18:00
  [Dr. Brent Laartz] Too much stress is a problem.
• 18:04
  [Dr. Brent Laartz] Some exercise is good,
• 18:06
  [Dr. Brent Laartz] but too much may be not good for you.
• 18:10
  [Dr. Brent Laartz] So there are multiple different studies showing some type of hormesis.
• 18:15
  [Dr. Brent Laartz] Um effect for a lot of different things.
• 18:19
  [Dr. Brent Laartz] Certainly,
• 18:19
  [Dr. Brent Laartz] there are medications that might be at play here.
• 18:22
  [Dr. Brent Laartz] You'd want to certain amount of some medication to help longevity.
• 18:27
  [Dr. Brent Laartz] But too much could be bad because it might be harmful,
• 18:29
  [Dr. Brent Laartz] right?
• 18:31
  [Dr. Brent Laartz] Again,
• 18:32
  [Dr. Brent Laartz] swimming is one of the...
• 18:35
  [Dr. Brent Laartz] sports here that actually does not have much of an effect here in this sport.
• 18:42
  [Dr. Brent Laartz] And again,
• 18:43
  [Dr. Brent Laartz] these are based on two prospective cohort studies.
• 18:48
  [Dr. Brent Laartz] And let's see here.
• 18:54
  [Dr. Brent Laartz] The w-shaped and the hormesis here is where what is being talked
• 19:01
  [Dr. Brent Laartz] about a lot right now.
• 19:03
  [Dr. Brent Laartz] And this is basically the variety.
• 19:05
  [Dr. Brent Laartz] If you take certain levels of activity,
• 19:08
  [Dr. Brent Laartz] especially in the third part here.
• 19:12
  [Dr. Brent Laartz] If you take this study,
• 19:14
  [Dr. Brent Laartz] and we're going to look just at the right-hand side of the graph here.
• 19:18
  [Dr. Brent Laartz] These were persons who had the most amount of activity.
• 19:23
  [Dr. Brent Laartz] And if...
• 19:24
  [Dr. Brent Laartz] There was only a small amount of variety and you really only
• 19:26
  [Dr. Brent Laartz] participated in one sport.
• 19:29
  [Dr. Brent Laartz] Let's say it's jogging.
• 19:31
  [Dr. Brent Laartz] And he didn't do any other kind of sport.
• 19:33
  [Dr. Brent Laartz] You were in the blue dashed line there.
• 19:37
  [Dr. Brent Laartz] And you can see that there is improvement in Mortality.
• 19:41
  [Dr. Brent Laartz] About a 10% decrease in mortality.
• 19:45
  [Dr. Brent Laartz] And then in the yellow.
• 19:48
  [Dr. Brent Laartz] You can see that with increasing variety,
• 19:51
  [Dr. Brent Laartz] having two or three sports that you're involved with.
• 19:54
  [Dr. Brent Laartz] Again,
• 19:55
  [Dr. Brent Laartz] there is an improvement there down to approximately 18 to 19%
• 20:01
  [Dr. Brent Laartz] decrease in mortality.
• 20:04
  [Dr. Brent Laartz] But the pink and these are the people who had the most variety in
• 20:12
  [Dr. Brent Laartz] their sports that they are.
• 20:14
  [Dr. Brent Laartz] Participating in And you can see there right at about 20% improvement.
• 20:20
  [Dr. Brent Laartz] Here is the study where they're basically harking and talking about about that variety.
• 20:27
  [Dr. Brent Laartz] And this makes sense,
• 20:29
  [Dr. Brent Laartz] right?
• 20:29
  [Dr. Brent Laartz] And we'll talk about this in just a second.
• 20:31
  [Dr. Brent Laartz] Basically,
• 20:32
  [Dr. Brent Laartz] just a really quick look at the left-hand side here.
• 20:36
  [Dr. Brent Laartz] And if these are the people who had the lowest amount of added activity,
• 20:40
  [Dr. Brent Laartz] you can see that neither of these,
• 20:42
  [Dr. Brent Laartz] a variety is not going to really impact things compared to just one
• 20:48
  [Dr. Brent Laartz] sport because you're really not.
• 20:51
  [Dr. Brent Laartz] Having that much physical activity to impact your mortality to begin with.
• 20:55
  [Dr. Brent Laartz] Perhaps these are in that spot where it was only five less than five
• 21:00
  [Dr. Brent Laartz] METs per week and/ or MET hours per week.
• 21:03
  [Dr. Brent Laartz] I should say,
• 21:04
  [Dr. Brent Laartz] and this may have been in that graph.
• 21:06
  [Dr. Brent Laartz] And certainly,
• 21:07
  [Dr. Brent Laartz] if you're jogging less than five MET hours per week,
• 21:10
  [Dr. Brent Laartz] it doesn't decrease that much.
• 21:12
  [Dr. Brent Laartz] Same thing with if you're doing that less than five MET hours per week.
• 21:15
  [Dr. Brent Laartz] In other words,
• 21:16
  [Dr. Brent Laartz] you know,
• 21:17
  [Dr. Brent Laartz] running or walking five minutes once a week.
• 21:22
  [Dr. Brent Laartz] Then...
• 21:23
  [Dr. Brent Laartz] why does it matter whether you're taking that five minutes and
• 21:26
  [Dr. Brent Laartz] splitting it up and doing One minute of walking one minute of walking,
• 21:30
  [Dr. Brent Laartz] one minute of tennis,
• 21:31
  [Dr. Brent Laartz] and one minute of something else.
• 21:32
  [Dr. Brent Laartz] So I'm just being a little bit exaggerating there,
• 21:36
  [Dr. Brent Laartz] but So.
• 21:39
  [Dr. Brent Laartz] This...
• 21:41
  [Dr. Brent Laartz] I think the right-hand part of this study and what everybody's talking about,
• 21:45
  [Dr. Brent Laartz] about the variety and the importance of variety in our exercise and
• 21:52
  [Dr. Brent Laartz] different sports that we do,
• 21:55
  [Dr. Brent Laartz] is a really telling situation.
• 21:58
  [Dr. Brent Laartz] Because really,
• 21:59
  [Dr. Brent Laartz] we already know that it's important to have both cardiovascular
• 22:03
  [Dr. Brent Laartz] fitness and strength fitness,
• 22:07
  [Dr. Brent Laartz] and grip strength,
• 22:08
  [Dr. Brent Laartz] leg strength,
• 22:09
  [Dr. Brent Laartz] and it's important to have that VO2 max be at the tip top,
• 22:15
  [Dr. Brent Laartz] and that will improve your longevity.
• 22:22
  [Dr. Brent Laartz] So this is an interesting part to this.
• 22:26
  [Dr. Brent Laartz] We're going to tease this out just a little bit more here.
• 22:31
  [Dr. Brent Laartz] And we'll talk about this.
• 22:32
  [Dr. Brent Laartz] Certainly,
• 22:33
  [Dr. Brent Laartz] if you're playing tennis and you're having great balance,
• 22:36
  [Dr. Brent Laartz] and if you are also jogging,
• 22:38
  [Dr. Brent Laartz] and therefore having great.
• 22:39
  [Dr. Brent Laartz] Vo2 max and you are also doing some the racket sports and having
• 22:46
  [Dr. Brent Laartz] some grip strength from playing that and all the balance that comes
• 22:51
  [Dr. Brent Laartz] with it and having all different of these activities and having a
• 22:55
  [Dr. Brent Laartz] high amount of activity like is on the right hand side of this graph,
• 22:59
  [Dr. Brent Laartz] then you're going to benefit the most out of that and have the least
• 23:03
  [Dr. Brent Laartz] likelihood of dying from all these.
• 23:06
  [Dr. Brent Laartz] The only caveat to this and this is this comes from the outside magazine.
• 23:13
  [Dr. Brent Laartz] They took one additional step and took the data from this study and put out this graph.
• 23:22
  [Dr. Brent Laartz] So this is from outside online.
• 23:24
  [Dr. Brent Laartz] Look at this graph here showing that there is a relative risk of premature death.
• 23:35
  [Dr. Brent Laartz] You can see that the way they adjusted it and here you can see that they come comes down to about 20 percent decreased risk of dying compared to Control.
• 23:49
  [Dr. Brent Laartz] But they adjusted these.
• 23:51
  [Dr. Brent Laartz] And they adjusted these and they controlled for BMI,
• 23:56
  [Dr. Brent Laartz] cholesterol,
• 23:56
  [Dr. Brent Laartz] family history of cardiovascular disease,
• 23:59
  [Dr. Brent Laartz] Ethnicity,
• 24:00
  [Dr. Brent Laartz] smoking status,
• 24:01
  [Dr. Brent Laartz] diet,
• 24:02
  [Dr. Brent Laartz] and blood pressure.
• 24:04
  [Dr. Brent Laartz] So...
• 24:05
  [Dr. Brent Laartz] Let's think about this.
• 24:06
  [Dr. Brent Laartz] Now,
• 24:07
  [Dr. Brent Laartz] a couple of those.
• 24:08
  [Dr. Brent Laartz] might not really be that much of a difference between the two,
• 24:14
  [Dr. Brent Laartz] control and the person who exercised a lot.
• 24:20
  [Dr. Brent Laartz] But...
• 24:22
  [Dr. Brent Laartz] Let's say your cholesterol,
• 24:23
  [Dr. Brent Laartz] your blood pressure,
• 24:24
  [Dr. Brent Laartz] your diet,
• 24:25
  [Dr. Brent Laartz] your BMI,
• 24:28
  [Dr. Brent Laartz] your smoking status— certainly would change,
• 24:30
  [Dr. Brent Laartz] right?
• 24:30
  [Dr. Brent Laartz] If you're putting in five...
• 24:35
  [Dr. Brent Laartz] If you're the fifth quintile of total weekly physical activity,
• 24:38
  [Dr. Brent Laartz] which is out here on the right,
• 24:41
  [Dr. Brent Laartz] and you are...
• 24:43
  [Dr. Brent Laartz] putting in a hundred mets hours per week,
• 24:46
  [Dr. Brent Laartz] are you likely to be a smoker?
• 24:50
  [Dr. Brent Laartz] And are you likely to have a high cholesterol?
• 24:52
  [Dr. Brent Laartz] And are you likely to have an abnormal blood pressure?
• 24:57
  [Dr. Brent Laartz] And are you likely to have an abnormal diet compared to a control person?
• 25:01
  [Dr. Brent Laartz] But if you then...
• 25:02
  [Dr. Brent Laartz] Take that person with that really good blood pressure and a really good cholesterol,
• 25:08
  [Dr. Brent Laartz] really good BMI,
• 25:10
  [Dr. Brent Laartz] and you compare him or her.
• 25:13
  [Dr. Brent Laartz] 2.
• 25:14
  [Dr. Brent Laartz] A person who is sedentary.
• 25:16
  [Dr. Brent Laartz] Who has that same really good blood pressure,
• 25:19
  [Dr. Brent Laartz] then you might not really have that much of a difference there,
• 25:22
  [Dr. Brent Laartz] right?
• 25:23
  [Dr. Brent Laartz] Potentially,
• 25:23
  [Dr. Brent Laartz] as you get out here to the fourth and fifth quintile of physical activity,
• 25:28
  [Dr. Brent Laartz] there could be...
• 25:30
  [Dr. Brent Laartz] A,
• 25:31
  [Dr. Brent Laartz] uh...
• 25:33
  [Dr. Brent Laartz] and actual confounding from doing too much.
• 25:37
  [Dr. Brent Laartz] Controlling.
• 25:38
  [Dr. Brent Laartz] And for some of these different.
• 25:41
  [Dr. Brent Laartz] effects right so.
• 25:43
  [Dr. Brent Laartz] So part of the benefit of that higher quantity of exercise is lower
• 25:47
  [Dr. Brent Laartz] cholesterol diet and blood pressure,
• 25:51
  [Dr. Brent Laartz] right?
• 25:51
  [Dr. Brent Laartz] So Why take that out?
• 25:53
  [Dr. Brent Laartz] Why make them be compared to a person who has normal blood pressure?
• 25:59
  [Dr. Brent Laartz] Why not just do a randomized controlled trial?
• 26:02
  [Dr. Brent Laartz] And obviously,
• 26:03
  [Dr. Brent Laartz] these are prospective cohort studies.
• 26:07
  [Dr. Brent Laartz] They're not randomized.
• 26:08
  [Dr. Brent Laartz] They're not They're not randomized and controlled.
• 26:14
  [Dr. Brent Laartz] These are,
• 26:14
  [Dr. Brent Laartz] um,
• 26:16
  [Dr. Brent Laartz] cohort-controlled studies.
• 26:21
  [Dr. Brent Laartz] This could be a confounding reason.
• 26:22
  [Dr. Brent Laartz] And so if you don't control that,
• 26:24
  [Dr. Brent Laartz] and you can see in the blue line here,
• 26:26
  [Dr. Brent Laartz] that if you don't adjust,
• 26:29
  [Dr. Brent Laartz] that those people continue to have a better relative risk of
• 26:35
  [Dr. Brent Laartz] premature death improvement all the way out to the fifth quintile.
• 26:40
  [Dr. Brent Laartz] And they have about a 35% decreased risk of death compared to the
• 26:44
  [Dr. Brent Laartz] other ones if you don't control for those things.
• 26:46
  [Dr. Brent Laartz] In other words,
• 26:47
  [Dr. Brent Laartz] take all comers who went to the fifth quintile versus the control,
• 26:51
  [Dr. Brent Laartz] and you...
• 26:52
  [Dr. Brent Laartz] Then,
• 26:55
  [Dr. Brent Laartz] look at that.
• 26:55
  [Dr. Brent Laartz] There is a 35% relative decreased risk of death.
• 27:00
  [Dr. Brent Laartz] And we can also kind of look toward the elite athlete studies above.
• 27:06
  [Dr. Brent Laartz] We had the previous studies that showed that persons who are
• 27:13
  [Dr. Brent Laartz] recreational had an improvement in their um...
• 27:22
  [Dr. Brent Laartz] longevity,
• 27:22
  [Dr. Brent Laartz] but then elite athletes,
• 27:25
  [Dr. Brent Laartz] similar athletes.
• 27:27
  [Dr. Brent Laartz] So for example,
• 27:28
  [Dr. Brent Laartz] jogging,
• 27:30
  [Dr. Brent Laartz] adding 3.
• 27:31
  [Dr. Brent Laartz] 2 years,
• 27:32
  [Dr. Brent Laartz] but yet endurance athletes,
• 27:34
  [Dr. Brent Laartz] which include runners.
• 27:37
  [Dr. Brent Laartz] had a 38% decreased risk of dying,
• 27:41
  [Dr. Brent Laartz] which probably,
• 27:41
  [Dr. Brent Laartz] and we didn't obviously see what the added years of life was here,
• 27:45
  [Dr. Brent Laartz] but it's probably...
• 27:47
  [Dr. Brent Laartz] compared to a control,
• 27:49
  [Dr. Brent Laartz] probably is going to be much more than 3.
• 27:51
  [Dr. Brent Laartz] 2 years.
• 27:52
  [Dr. Brent Laartz] So that kind of goes toward that same showing,
• 27:58
  [Dr. Brent Laartz] okay?
• 27:58
  [Dr. Brent Laartz] So that,
• 28:00
  [Dr. Brent Laartz] so some takeaways from here,
• 28:03
  [Dr. Brent Laartz] we're going to,
• 28:03
  [Dr. Brent Laartz] let's stop sharing here.
• 28:07
  [Dr. Brent Laartz] Uh...
• 28:09
  [Dr. Brent Laartz] Stop our share and bring us back to here and our takeaways here
• 28:12
  [Dr. Brent Laartz] about the variety of sports.
• 28:15
  [Dr. Brent Laartz] If I am involved with tennis,
• 28:18
  [Dr. Brent Laartz] let's say.
• 28:19
  [Dr. Brent Laartz] and I'm involved with jogging,
• 28:21
  [Dr. Brent Laartz] and I'm involved with soccer,
• 28:23
  [Dr. Brent Laartz] and I'm involved with some other sport that involves strength
• 28:28
  [Dr. Brent Laartz] training and/ or some sport that requires strength training,
• 28:32
  [Dr. Brent Laartz] because certainly running doesn't require that much strength training,
• 28:36
  [Dr. Brent Laartz] then I'm going to have the best of all.
• 28:40
  [Dr. Brent Laartz] of these different worlds,
• 28:41
  [Dr. Brent Laartz] because what does it take for a human as opposed to a laboratory
• 28:47
  [Dr. Brent Laartz] animal which we can we know there are a lot of different studies
• 28:50
  [Dr. Brent Laartz] with laboratory animals and longevity,
• 28:52
  [Dr. Brent Laartz] and it's difficult to do with humans.
• 28:54
  [Dr. Brent Laartz] But we know that humans need these kind of things to live longer.
• 28:59
  [Dr. Brent Laartz] They need cardiovascular fitness,
• 29:02
  [Dr. Brent Laartz] they need this grip strength and/ or other measures of strength.
• 29:08
  [Dr. Brent Laartz] You also need balance,
• 29:10
  [Dr. Brent Laartz] because you don't want to fall,
• 29:11
  [Dr. Brent Laartz] because falling is a huge part of our problem in older age that
• 29:17
  [Dr. Brent Laartz] leads to morbidity and leads to inactivity.
• 29:20
  [Dr. Brent Laartz] We need to keep a good cognition.
• 29:23
  [Dr. Brent Laartz] We need to keep good social connections and cognitive demands.
• 29:30
  [Dr. Brent Laartz] A full body engagement.
• 29:32
  [Dr. Brent Laartz] So that variety of sports.
• 29:34
  [Dr. Brent Laartz] Now the above study,
• 29:36
  [Dr. Brent Laartz] the first study we talked about where racket sports were important,
• 29:39
  [Dr. Brent Laartz] right?
• 29:39
  [Dr. Brent Laartz] So certainly these sports kind of also have the best of all worlds.
• 29:44
  [Dr. Brent Laartz] They do have a high intensity interval training.
• 29:46
  [Dr. Brent Laartz] So they have They have a spike in heart rate and then recover repeatedly.
• 29:50
  [Dr. Brent Laartz] And that improves heart rate variability.
• 29:52
  [Dr. Brent Laartz] That improves heart rate recovery.
• 29:57
  [Dr. Brent Laartz] ability to recover which is very important for our cardiovascular
• 30:01
  [Dr. Brent Laartz] exercise and our VO2 max.
• 30:04
  [Dr. Brent Laartz] Okay,
• 30:04
  [Dr. Brent Laartz] so it requires full body engagement.
• 30:07
  [Dr. Brent Laartz] So you're not only using your arms to to hit the ball over the net.
• 30:11
  [Dr. Brent Laartz] You're also using your feet to run side to side,
• 30:14
  [Dr. Brent Laartz] forward,
• 30:15
  [Dr. Brent Laartz] and backwards.
• 30:16
  [Dr. Brent Laartz] And you're using your whole shoulder girdle.
• 30:19
  [Dr. Brent Laartz] You're using your hips,
• 30:20
  [Dr. Brent Laartz] knees,
• 30:20
  [Dr. Brent Laartz] and getting down.
• 30:22
  [Dr. Brent Laartz] Uh,
• 30:22
  [Dr. Brent Laartz] lower potentially,
• 30:23
  [Dr. Brent Laartz] and or jumping a lot of different full body engagements.
• 30:27
  [Dr. Brent Laartz] You use there also.
• 30:28
  [Dr. Brent Laartz] There's a social component racket sports,
• 30:30
  [Dr. Brent Laartz] um,
• 30:31
  [Dr. Brent Laartz] and certainly other team sports are important here.
• 30:34
  [Dr. Brent Laartz] And I think that's why some of these team sports,
• 30:36
  [Dr. Brent Laartz] such as soccer,
• 30:37
  [Dr. Brent Laartz] were in the middle here,
• 30:39
  [Dr. Brent Laartz] whereas jogging and walking were less likely.
• 30:42
  [Dr. Brent Laartz] Because there's less social engagement there.
• 30:44
  [Dr. Brent Laartz] Cognitive demands here of a racket sport versus some other sports
• 30:49
  [Dr. Brent Laartz] don't take much cognitive demand to jog five miles,
• 30:54
  [Dr. Brent Laartz] let's say,
• 30:55
  [Dr. Brent Laartz] for example,
• 30:55
  [Dr. Brent Laartz] like what I did today.
• 30:57
  [Dr. Brent Laartz] I basically had a tracker that tracked exactly how far I was going.
• 31:01
  [Dr. Brent Laartz] I had to read the numbers periodically,
• 31:03
  [Dr. Brent Laartz] and the thing told me exactly how.
• 31:05
  [Dr. Brent Laartz] Thank you.
• 31:05
  [Dr. Brent Laartz] Uh,
• 31:06
  [Dr. Brent Laartz] fast I was going.
• 31:08
  [Dr. Brent Laartz] Now it's kind of all done for us,
• 31:09
  [Dr. Brent Laartz] but...
• 31:10
  [Dr. Brent Laartz] Tennis,
• 31:10
  [Dr. Brent Laartz] you have to really keep score,
• 31:12
  [Dr. Brent Laartz] keep track,
• 31:13
  [Dr. Brent Laartz] keep...
• 31:13
  [Dr. Brent Laartz] Keep figuring out where exactly the line is and judgment.
• 31:18
  [Dr. Brent Laartz] And a lot of hand-eye coordination there.
• 31:22
  [Dr. Brent Laartz] And it also involves grip strength.
• 31:23
  [Dr. Brent Laartz] So you're gripping a racket,
• 31:25
  [Dr. Brent Laartz] right?
• 31:25
  [Dr. Brent Laartz] So it involves a lot of forearm activity to really— either put
• 31:31
  [Dr. Brent Laartz] forward spin on the ball or maybe backspin.
• 31:34
  [Dr. Brent Laartz] And it requires balance.
• 31:36
  [Dr. Brent Laartz] You are starting and stopping.
• 31:38
  [Dr. Brent Laartz] You are.
• 31:39
  [Dr. Brent Laartz] Moving to the sideline.
• 31:41
  [Dr. Brent Laartz] or to the end line,
• 31:42
  [Dr. Brent Laartz] and you have to stop immediately,
• 31:44
  [Dr. Brent Laartz] you have to hit that ball,
• 31:46
  [Dr. Brent Laartz] and you have to hit that ball with a force that then you don't want
• 31:50
  [Dr. Brent Laartz] to fall after you do it.
• 31:52
  [Dr. Brent Laartz] And certainly,
• 31:53
  [Dr. Brent Laartz] people who are less active are finding this out with pickleball
• 31:58
  [Dr. Brent Laartz] because pickleball is a sport where there's becoming a lot of injuries of people.
• 32:03
  [Dr. Brent Laartz] who are getting involved and getting involved when they weren't
• 32:06
  [Dr. Brent Laartz] involved in sports before.
• 32:08
  [Dr. Brent Laartz] So badminton and tennis were.
• 32:13
  [Dr. Brent Laartz] Some of the highest recreational sports involved here in our first
• 32:18
  [Dr. Brent Laartz] study we talked about.
• 32:20
  [Dr. Brent Laartz] Injury is important.
• 32:21
  [Dr. Brent Laartz] The takeaway from injury and maybe traumatic brain injury in other sports,
• 32:28
  [Dr. Brent Laartz] such as football,
• 32:30
  [Dr. Brent Laartz] boxing,
• 32:33
  [Dr. Brent Laartz] which have potentially either the same or less or barely better
• 32:38
  [Dr. Brent Laartz] survivability compared to control of people who are not in.
• 32:43
  [Dr. Brent Laartz] In sports,
• 32:44
  [Dr. Brent Laartz] so and then cardiovascular and strength are important.
• 32:48
  [Dr. Brent Laartz] The social and cognitive benefits of multiple of these different sports is important.
• 32:53
  [Dr. Brent Laartz] Swimming seems to be less there's it's a solo sport,
• 32:57
  [Dr. Brent Laartz] although there is teams.
• 32:58
  [Dr. Brent Laartz] Obviously,
• 32:58
  [Dr. Brent Laartz] there but we're talking about people who are who are potentially
• 33:08
  [Dr. Brent Laartz] very cardiovascularly fit,
• 33:10
  [Dr. Brent Laartz] right?
• 33:11
  [Dr. Brent Laartz] Think of Michael Phelps and how cardiovascularly fit he is.
• 33:14
  [Dr. Brent Laartz] But this is,
• 33:15
  [Dr. Brent Laartz] I think,
• 33:16
  [Dr. Brent Laartz] we were talking about elite sports.
• 33:20
  [Dr. Brent Laartz] But swimming was not one of those studied.
• 33:22
  [Dr. Brent Laartz] We were talking about the recreational sports when we were talking
• 33:26
  [Dr. Brent Laartz] about swimming was right in the middle.
• 33:28
  [Dr. Brent Laartz] Again,
• 33:29
  [Dr. Brent Laartz] jogging was.
• 33:30
  [Dr. Brent Laartz] Lower calisthenics was lower.
• 33:32
  [Dr. Brent Laartz] Health club and gym,
• 33:33
  [Dr. Brent Laartz] basically,
• 33:34
  [Dr. Brent Laartz] the same as a control sedentary person.
• 33:37
  [Dr. Brent Laartz] Um okay and again linemen in pro football sports,
• 33:42
  [Dr. Brent Laartz] not so good,
• 33:44
  [Dr. Brent Laartz] but other positional players were better.
• 33:46
  [Dr. Brent Laartz] And I think some of this has to,
• 33:48
  [Dr. Brent Laartz] and other sports such as what we talked about,
• 33:53
  [Dr. Brent Laartz] power sports,
• 33:54
  [Dr. Brent Laartz] boxing,
• 33:54
  [Dr. Brent Laartz] wrestling,
• 33:55
  [Dr. Brent Laartz] weightlifting,
• 33:56
  [Dr. Brent Laartz] and throwing,
• 33:56
  [Dr. Brent Laartz] which have a lot of strength training,
• 34:00
  [Dr. Brent Laartz] but not so much cardiovascular.
• 34:01
  [Dr. Brent Laartz] I'd beg to differ about wrestling.
• 34:03
  [Dr. Brent Laartz] I don't know if they're talking about professional wrestling here
• 34:05
  [Dr. Brent Laartz] versus college wrestling,
• 34:07
  [Dr. Brent Laartz] but I can beg to differ about wrestling.
• 34:09
  [Dr. Brent Laartz] About how much VO2 max we had,
• 34:12
  [Dr. Brent Laartz] but there potentially is injury there.
• 34:14
  [Dr. Brent Laartz] And so these power sports and/ or contact sports have...
• 34:19
  [Dr. Brent Laartz] Being linemen less likely to give you a survival benefit and
• 34:24
  [Dr. Brent Laartz] longevity benefit if you are participating in these again—I can't
• 34:29
  [Dr. Brent Laartz] stress enough— and I would like to incorporate this into my life is
• 34:35
  [Dr. Brent Laartz] the variety of sports.
• 34:36
  [Dr. Brent Laartz] And I already love a variety of sports.
• 34:38
  [Dr. Brent Laartz] Already hiking,
• 34:39
  [Dr. Brent Laartz] running,
• 34:39
  [Dr. Brent Laartz] and doing a lot of different things.
• 34:42
  [Dr. Brent Laartz] That,
• 34:42
  [Dr. Brent Laartz] and I've been involved in tennis in the past,
• 34:45
  [Dr. Brent Laartz] and I haven't played tennis as much recently,
• 34:47
  [Dr. Brent Laartz] but I'm going to get more involved again,
• 34:49
  [Dr. Brent Laartz] especially now that I hear, 'Hey,
• 34:51
  [Dr. Brent Laartz] we live longer if you play tennis.' Right.
• 34:54
  [Dr. Brent Laartz] But I think it's the variety of sports.
• 34:56
  [Dr. Brent Laartz] That's the important thing.
• 34:57
  [Dr. Brent Laartz] OK,
• 34:57
  [Dr. Brent Laartz] so.
• 34:59
  [Dr. Brent Laartz] All right.
• 35:00
  [Dr. Brent Laartz] So thank you for.
• 35:02
  [Dr. Brent Laartz] Hanging out with here tonight on a Sunday.
• 35:06
  [Dr. Brent Laartz] Right after the Super Bowl.
• 35:08
  [Dr. Brent Laartz] Um...
• 35:09
  [Dr. Brent Laartz] Great game.
• 35:11
  [Dr. Brent Laartz] Showing that the elite in sport.
• 35:15
  [Dr. Brent Laartz] It's amazing,
• 35:16
  [Dr. Brent Laartz] some of the study,
• 35:17
  [Dr. Brent Laartz] big defensive game,
• 35:18
  [Dr. Brent Laartz] a lot of punts,
• 35:19
  [Dr. Brent Laartz] a lot of kicking,
• 35:20
  [Dr. Brent Laartz] right?
• 35:20
  [Dr. Brent Laartz] So those would be your other positional players,
• 35:23
  [Dr. Brent Laartz] the punters and the kickers.
• 35:25
  [Dr. Brent Laartz] Uh,
• 35:26
  [Dr. Brent Laartz] that was playing this game 90 of the time,
• 35:29
  [Dr. Brent Laartz] these people were the ones that won the game,
• 35:33
  [Dr. Brent Laartz] but they're also potentially ones that might live the longest.
• 35:35
  [Dr. Brent Laartz] They are,
• 35:36
  [Dr. Brent Laartz] usually,
• 35:38
  [Dr. Brent Laartz] as strong as some of our other positional sports.
• 35:41
  [Dr. Brent Laartz] And they do have some of the cardiovascular improvement also.
• 35:46
  [Dr. Brent Laartz] So potentially,
• 35:47
  [Dr. Brent Laartz] the game was won by the people who will live the longest,
• 35:50
  [Dr. Brent Laartz] maybe potentially.
• 35:51
  [Dr. Brent Laartz] So let's see.
• 35:53
  [Dr. Brent Laartz] So I appreciate you hanging out with me and I appreciate you coming
• 36:01
  [Dr. Brent Laartz] along with me on my ride of trying to live longer,
• 36:04
  [Dr. Brent Laartz] trying to live healthier.
• 36:06
  [Dr. Brent Laartz] and trying to find out what to do,
• 36:08
  [Dr. Brent Laartz] what the science is behind all of this.
• 36:11
  [Dr. Brent Laartz] And I look forward to seeing you again.
• 36:14
  [Dr. Brent Laartz] Again,
• 36:14
  [Dr. Brent Laartz] we are on YouTube.
• 36:18
  [Dr. Brent Laartz] There's also two YouTubes: Go On Pro and my Brent W.
• 36:22
  [Dr. Brent Laartz] Lartz MD page.
• 36:23
  [Dr. Brent Laartz] There is a sub stack for Brent W.
• 36:25
  [Dr. Brent Laartz] Lartz,
• 36:26
  [Dr. Brent Laartz] the Go On Pro podcast.
• 36:27
  [Dr. Brent Laartz] And there is the GoUnPro .
• 36:30
  [Dr. Brent Laartz] com website.
• 36:31
  [Dr. Brent Laartz] So GoUnPro,

  [Dr. Brent Laartz] and Threads,
• 36:48
  [Dr. Brent Laartz] and Substack.
• 36:50
  [Dr. Brent Laartz] We have some social media there as well.
• 36:52
  [Dr. Brent Laartz] Look forward to talking with you.
• 36:54
  [Dr. Brent Laartz] We start tomorrow.
• 36:57
  [Dr. Brent Laartz] And we are announcing this already to the world that we are tomorrow
• 37:02
  [Dr. Brent Laartz] starting with a Monday night,
• 37:04
  [Dr. Brent Laartz] 8 o'clock.
• 37:07
  [Dr. Brent Laartz] Great.
• 37:09
  [Dr. Brent Laartz] Zoom call,
• 37:11
  [Dr. Brent Laartz] 30 minutes,
• 37:12
  [Dr. Brent Laartz] every Monday.
• 37:13
  [Dr. Brent Laartz] And we're going to be basically just providing a community for
• 37:17
  [Dr. Brent Laartz] everyone out there to get in.
• 37:19
  [Dr. Brent Laartz] involved and see what I'm doing.
• 37:23
  [Dr. Brent Laartz] This is not a medical advice system.
• 37:29
  [Dr. Brent Laartz] is just creating a community where you can talk to everyone.
• 37:33
  [Dr. Brent Laartz] We can comment and bring everybody in to meet each other.
• 37:39
  [Dr. Brent Laartz] have some camaraderie around getting our best foot forward in the areas of diet,
• 37:46
  [Dr. Brent Laartz] exercise,
• 37:47
  [Dr. Brent Laartz] sleep,
• 37:48
  [Dr. Brent Laartz] and creativity and connection.
• 37:52
  [Dr. Brent Laartz] This is what I'm trying to create,
• 37:54
  [Dr. Brent Laartz] that fourth pillar out of the five pillars.
• 37:56
  [Dr. Brent Laartz] We have five pillars.
• 37:57
  [Dr. Brent Laartz] Five-sided table,
• 37:58
  [Dr. Brent Laartz] right?
• 37:58
  [Dr. Brent Laartz] So it's a pentagon table.
• 38:00
  [Dr. Brent Laartz] Five legs.
• 38:02
  [Dr. Brent Laartz] The fourth leg here— connectivity and connection with every one of you.
• 38:06
  [Dr. Brent Laartz] I want to connect with you and I want you to connect with me to try
• 38:10
  [Dr. Brent Laartz] to figure out what we need to do.
• 38:13
  [Dr. Brent Laartz] We are not gonna be on this same journey,
• 38:17
  [Dr. Brent Laartz] down the exact same path.
• 38:19
  [Dr. Brent Laartz] I appreciate what everybody's doing to improve their life.
• 38:26
  [Dr. Brent Laartz] Half of it is up here in our brain,
• 38:29
  [Dr. Brent Laartz] right?
• 38:29
  [Dr. Brent Laartz] Up here in our mind and what we can do.
• 38:33
  [Dr. Brent Laartz] That connectivity and that accountability.
• 38:36
  [Dr. Brent Laartz] Me having you and you having me there to support us.
• 38:40
  [Dr. Brent Laartz] Support everyone is what's important.
• 38:43
  [Dr. Brent Laartz] And that is what we're going to try to create here with this Zoom
• 38:47
  [Dr. Brent Laartz] call every Monday night at eight o'clock.
• 38:50
  [Dr. Brent Laartz] Okay.
• 38:51
  [Dr. Brent Laartz] So join us.
• 38:52
  [Dr. Brent Laartz] If you are a member of the Substack community,
• 38:59
  [Dr. Brent Laartz] and you can be a free member for now.
• 39:02
  [Dr. Brent Laartz] At some point,
• 39:03
  [Dr. Brent Laartz] you might have to be a paid member to be part of this Zoom.
• 39:05
  [Dr. Brent Laartz] But right now,
• 39:06
  [Dr. Brent Laartz] it's going to be free.
• 39:07
  [Dr. Brent Laartz] Everyone we're going to allow as many people as can fit.
• 39:11
  [Dr. Brent Laartz] I don't have a premium Zoom account,
• 39:14
  [Dr. Brent Laartz] so it's it may be limited at some point.
• 39:17
  [Dr. Brent Laartz] If,
• 39:18
  [Dr. Brent Laartz] for example,
• 39:20
  [Dr. Brent Laartz] we have enough paying users,
• 39:22
  [Dr. Brent Laartz] I might pay for the premium Zoom or whatever.
• 39:25
  [Dr. Brent Laartz] Who knows.
• 39:25
  [Dr. Brent Laartz] But I appreciate you being there.
• 39:28
  [Dr. Brent Laartz] I appreciate you.
• 39:29
  [Dr. Brent Laartz] We may have zero people on the call and I'll be hanging out with
• 39:33
  [Dr. Brent Laartz] myself and my girlfriend and my dogs and we'll hang out.
• 39:37
  [Dr. Brent Laartz] Talk and maybe I'll talk to my dogs about how I'm taking them out
• 39:41
  [Dr. Brent Laartz] for a walk and and I'm improving the diet of my dogs and that kind of thing.
• 39:46
  [Dr. Brent Laartz] My girlfriend is participating along with me on on this crazy carpet
• 39:51
  [Dr. Brent Laartz] ride through longevity.
• 39:53
  [Dr. Brent Laartz] I love being here and I love discussing it with you.
• 39:58
  [Dr. Brent Laartz] Love having my own accountability.
• 40:01
  [Dr. Brent Laartz] Love having my own.
• 40:03
  [Dr. Brent Laartz] Plan.
• 40:04
  [Dr. Brent Laartz] Weekly to try to get better,
• 40:06
  [Dr. Brent Laartz] every week to advance myself down the line.
• 40:10
  [Dr. Brent Laartz] Toward living better and longer.
• 40:13
  [Dr. Brent Laartz] I'm trying to change the family dynamic.
• 40:17
  [Dr. Brent Laartz] In other words,
• 40:18
  [Dr. Brent Laartz] from my parents.
• 40:19
  [Dr. Brent Laartz] Who lived and,
• 40:21
  [Dr. Brent Laartz] and basically came of age in the industrial processed world,
• 40:25
  [Dr. Brent Laartz] took full advantage of it,
• 40:28
  [Dr. Brent Laartz] though they certainly fed us good unprocessed foods at times.
• 40:33
  [Dr. Brent Laartz] At times.
• 40:34
  [Dr. Brent Laartz] But they bought into the Cheerios.
• 40:36
  [Dr. Brent Laartz] They bought into the macaroni and cheese.
• 40:40
  [Dr. Brent Laartz] They bought into the canned beef stews and that kind of thing for us sometimes.
• 40:46
  [Dr. Brent Laartz] And tried to make them,
• 40:48
  [Dr. Brent Laartz] they had a better life after that,
• 40:51
  [Dr. Brent Laartz] right?
• 40:51
  [Dr. Brent Laartz] And so a better life was a simpler life,
• 40:55
  [Dr. Brent Laartz] but it wasn't the way.
• 40:56
  [Dr. Brent Laartz] Their grandparents lived which was actually the better life even
• 41:00
  [Dr. Brent Laartz] though it was a tough life for our grandparents' great-grandparents
• 41:02
  [Dr. Brent Laartz] who were having to till their own land and make plant their own
• 41:06
  [Dr. Brent Laartz] foods grow their own foods that process of doing some of your own
• 41:12
  [Dr. Brent Laartz] thing don't think that it's going to be easy.
• 41:15
  [Dr. Brent Laartz] To do this and be have an unprocessed life.
• 41:19
  [Dr. Brent Laartz] I'm going to need to learn to plant my own food.
• 41:22
  [Dr. Brent Laartz] I'm already fermenting my own food.
• 41:23
  [Dr. Brent Laartz] I've been doing that for years.
• 41:25
  [Dr. Brent Laartz] And creating my own hot sauces,
• 41:27
  [Dr. Brent Laartz] creating my own.
• 41:29
  [Dr. Brent Laartz] Different products that I can use.
• 41:32
  [Dr. Brent Laartz] To decrease the amounts of plastic and processed foods in my life.
• 41:36
  [Dr. Brent Laartz] So thank you very much.
• 41:37
  [Dr. Brent Laartz] I look forward to seeing you guys tomorrow night.
• 41:40
  [Dr. Brent Laartz] Again,
• 41:40
  [Dr. Brent Laartz] happy Sunday.
• 41:42
  [Dr. Brent Laartz] Appreciate you being here.
