WEBVTT - Better Living Through Fitness Science 0:00:00.160 --> 0:00:07.440 Brought to you by Toyota. Let's go places. Welcome to 0:00:07.600 --> 0:00:16.040 Forward Thinking. Hello, and welcome to Forward Thinking. The podcast 0:00:16.040 --> 0:00:17.639 it looks at the future and says, they tell me 0:00:17.680 --> 0:00:19.720 that it's good for me, but I don't even care. 0:00:20.120 --> 0:00:24.960 I'm Lauren Vogelba, I'm Joe McCormick, and I'm Holly Fry. Yes, yes, 0:00:25.239 --> 0:00:28.560 Jonathan is out on vacation today, but Holly, being a 0:00:28.600 --> 0:00:31.920 fitness enthusiast, is joining us again. If you tune into 0:00:31.920 --> 0:00:35.239 the last episode, you have already borne witness to our 0:00:35.320 --> 0:00:38.960 shenanigans and we're just tickled pink to have her. We 0:00:38.960 --> 0:00:43.680 we certainly are. Thank you, say my favorite God. So 0:00:43.720 --> 0:00:47.360 we are continuing today to talk about fitness. We wanted 0:00:47.400 --> 0:00:50.600 to to talk more about the the science and what 0:00:50.760 --> 0:00:53.440 we know and what we absolutely don't know, and how 0:00:53.440 --> 0:00:55.440 exciting all of this future research is going to be. 0:00:55.680 --> 0:00:58.160 One thing that I think is amazing about fitness is 0:00:58.200 --> 0:01:01.240 this is such a basic issue and there's so much 0:01:01.320 --> 0:01:04.959 that like we're still discovering and still haven't things we 0:01:04.959 --> 0:01:08.160 still haven't settled. Blows my mind. Well, sure, I mean 0:01:08.200 --> 0:01:10.280 we've basically been human beings the way that we think 0:01:10.319 --> 0:01:13.920 of human beings for you know, tens of thousands of 0:01:14.000 --> 0:01:18.759 years I think years that and and we're still really 0:01:18.800 --> 0:01:21.480 mystified by how our bodies work, which is I mean 0:01:21.560 --> 0:01:23.639 partially because of the fact that all of our bodies 0:01:23.640 --> 0:01:26.080 are very slightly different, which MUCKs things up. And there's 0:01:26.080 --> 0:01:28.040 a lot of factors involved. You know, what we're eating 0:01:28.120 --> 0:01:34.080 and where we're living and uh frog, science is unanimous 0:01:34.160 --> 0:01:36.200 that the best thing for us is to sit at 0:01:36.200 --> 0:01:38.760 a desk and watch YouTube all day. Well, then I 0:01:38.800 --> 0:01:44.640 am set. Fortunately, actually that is not what science agrees 0:01:44.760 --> 0:01:46.640 is the best for us. No, and we went into 0:01:46.680 --> 0:01:48.720 that in depth in the last episode. But Joe, can 0:01:48.720 --> 0:01:51.400 you recap it for us? Really brief recap? Okay, So 0:01:52.120 --> 0:01:55.720 everybody needs exercise. You already know this, but just be 0:01:56.080 --> 0:01:59.720 assured it is a true science fact. Exercise is good 0:01:59.720 --> 0:02:03.440 for you. The US Health Department recommends that all healthy 0:02:03.480 --> 0:02:06.600 adult individuals get a minimum of a hundred and fifty 0:02:06.600 --> 0:02:11.320 minutes of moderate intensity aerobic activity every week, or seventy 0:02:11.360 --> 0:02:14.520 five minutes of vigorous activity. So basically what that means 0:02:14.639 --> 0:02:18.440 is like a hundred and fifty minutes of of modern 0:02:18.480 --> 0:02:21.600 intensity walking, say where your heart rates elevated a little 0:02:21.639 --> 0:02:24.360 bit or or lighter tasks like you know, gardening and 0:02:24.400 --> 0:02:27.480 stuff stuff like that. Um or seventy five minutes of 0:02:27.520 --> 0:02:30.720 like hard running or intense sport playing something like that, 0:02:30.800 --> 0:02:34.600 plus two sessions of strength training per week. And how 0:02:34.639 --> 0:02:38.160 are we doing? Well? We're not quite getting there. Less 0:02:38.200 --> 0:02:41.880 than as of the first six months of twelve, less 0:02:41.880 --> 0:02:45.840 than half of American adults were meeting these we're meeting 0:02:45.960 --> 0:02:50.360 just the goal for aerobic activity and about what was 0:02:50.360 --> 0:02:53.520 it twenty point seven percent of Americans between twenty five 0:02:53.560 --> 0:02:56.440 and sixty four are meeting both of these requirements for 0:02:56.440 --> 0:03:00.480 the aerobic activity and the strength training. Uh so, so 0:03:00.480 --> 0:03:02.839 we're so we're doing We're doing kind of all right, 0:03:03.040 --> 0:03:07.680 not not not could be great great, Yeah, but we'd 0:03:07.680 --> 0:03:11.680 like to talk a bit about, um, how science may 0:03:11.760 --> 0:03:15.080 inform the way we make fitness decisions in the future 0:03:15.240 --> 0:03:19.480 and reach our fitness goals. And uh it achieved greater 0:03:19.600 --> 0:03:25.400 performance and utter excellence and mystical power. I can't wait, 0:03:26.440 --> 0:03:29.040 can't wait for my mystical powers to kick in. Tell 0:03:29.080 --> 0:03:31.360 us about your mystical powers. I'm going to keep running 0:03:31.360 --> 0:03:33.960 and running and running until I can alter space with 0:03:34.000 --> 0:03:38.400 my mind. Oh wow, that sounds pretty good. You have 0:03:38.480 --> 0:03:41.320 you have a much bigger goal I have. I think 0:03:41.360 --> 0:03:44.520 I have like a like actually work out that that 0:03:44.640 --> 0:03:46.600 couple of times a week that Joe was talking about. 0:03:46.640 --> 0:03:49.160 That's my main goal right now, not not ending the 0:03:49.200 --> 0:03:51.680 time space continuum through my workouts. Well he promised you 0:03:51.760 --> 0:03:55.400 mystical powers. Hello, Okay, I'm working on a trick where 0:03:55.440 --> 0:03:58.000 I do push ups, but I'm staying in place and 0:03:58.040 --> 0:04:01.360 moving the earth. I think when you get there, I 0:04:01.480 --> 0:04:03.560 want to witness it. It's going to be cool. All right. 0:04:03.600 --> 0:04:07.320 So this does all tie into to the science of motivations. 0:04:07.720 --> 0:04:09.600 Um and uh like, like we said a little bit 0:04:09.600 --> 0:04:13.200 in the last episode, Um, you know, these these are 0:04:13.240 --> 0:04:16.040 really important for how much exercise you wind up actually getting. 0:04:16.120 --> 0:04:19.240 UM and and all sorts of things like like the enjoyment, 0:04:19.360 --> 0:04:23.919 the challenges. You know, personal motivators like like appearance and 0:04:23.920 --> 0:04:26.839 weight management and stress management can all be reasons that 0:04:26.920 --> 0:04:30.320 people work out. Um. Those first to the the enjoyment 0:04:30.360 --> 0:04:32.320 and the challenge of it tend to be really good 0:04:32.560 --> 0:04:35.480 indicators of adherence to exercise, which basically means that we 0:04:35.480 --> 0:04:39.120 should all be playing sports or gamifying things. Again, like 0:04:39.160 --> 0:04:42.880 we were saying in the last episode, that's pretty rad um. 0:04:42.920 --> 0:04:46.560 The the prefrontal cortex rules a lot of how motivated 0:04:46.640 --> 0:04:48.839 we are about stuff, because that's that's where we reason 0:04:48.880 --> 0:04:52.720 and make choices in response to stimuli. Unfortunately, this can 0:04:52.800 --> 0:04:56.200 kind of work against us because being physically unfit means 0:04:56.279 --> 0:04:58.840 that it is harder to exercise and that people want 0:04:58.880 --> 0:05:02.719 to do it less um and and as you know, conversely, 0:05:02.760 --> 0:05:05.680 as you get more fit, you have better motivation because 0:05:05.720 --> 0:05:08.200 you're probably you've fallen into a routine, you might have 0:05:08.279 --> 0:05:10.560 some kind of social contract going on, you're having fun, 0:05:10.960 --> 0:05:13.880 and it also just feels better at that point, right. Sure, times, 0:05:14.160 --> 0:05:16.240 the startup has a lot of eggs and pains to it, 0:05:16.560 --> 0:05:19.960 whether you have extra weight or not. Even people that 0:05:20.040 --> 0:05:22.400 look very fit sometimes aren't. In the startup is just 0:05:22.440 --> 0:05:26.120 painful and awful, and it's hard to sustain, you know, 0:05:26.160 --> 0:05:29.200 those first couple of weeks, No, I really want to 0:05:29.279 --> 0:05:31.080 keep going. But once you're into it and your body's 0:05:31.080 --> 0:05:33.080 accustomed to the movement, it feels better and you want 0:05:33.120 --> 0:05:34.880 to do it more, right right. A lot of people 0:05:34.920 --> 0:05:37.719 talk also about the adrenaline rush that you'll get from 0:05:37.760 --> 0:05:41.560 pushing your muscles to a certain point. The runners high. Yeah, 0:05:41.760 --> 0:05:45.000 that's real. I'm not kidding that you read about it 0:05:45.040 --> 0:05:47.000 the first time. It actually happened to me. After I 0:05:47.000 --> 0:05:48.880 started running, I thought I was having a stroke. I'm 0:05:48.920 --> 0:05:51.240 not kidding. Like, I pulled my car over because I 0:05:51.320 --> 0:05:53.120 was like, there's no reason I should be this giddy 0:05:53.200 --> 0:05:56.599 for no utter, I'm just driving down the street. Um. 0:05:56.600 --> 0:05:58.640 It was very bizarre and wonderful. Now I know what 0:05:58.680 --> 0:06:00.520 it is, and I know I am not experiencing a 0:06:00.560 --> 0:06:05.120 cerebral event of concern. It's amazing. It feels like I 0:06:05.240 --> 0:06:07.719 felt it. It feels like life is good and I 0:06:07.760 --> 0:06:11.520 want a burrito. Mine was more like screechy happiness, like 0:06:11.600 --> 0:06:15.000 when you creshed a roller coaster. Like, like, it was 0:06:15.120 --> 0:06:17.880 very bizarre. You see why I pulled over. It's like 0:06:18.000 --> 0:06:19.840 I might not be fit to conduct a vehicle at 0:06:19.839 --> 0:06:24.200 this time. Um, But then it passed. It was getting okay. 0:06:26.200 --> 0:06:27.880 So so so these are all These are all kind 0:06:27.880 --> 0:06:31.200 of in brain hormonal sort of things going on there. 0:06:31.200 --> 0:06:35.200 There is research that motivation might have a genetic component. Um. 0:06:35.240 --> 0:06:37.360 There is a study done at the University of Missouri 0:06:37.480 --> 0:06:40.880 with two groups of rats that that through breeding they 0:06:40.920 --> 0:06:43.159 created one that really loved to run a lot and 0:06:43.200 --> 0:06:46.040 the other were just a little ratty couch potatoes. UM 0:06:46.040 --> 0:06:48.640 through through a series of ten generations of of tracking 0:06:48.640 --> 0:06:52.440 how much rats and each breeding group enjoyed running, Like 0:06:52.480 --> 0:06:54.360 how much given the chance to they would just run 0:06:54.400 --> 0:06:57.680 on their own and uh and interbreeding um the two 0:06:57.800 --> 0:07:01.360 the two groups to greater exclusivity. So, I mean that's 0:07:01.360 --> 0:07:03.400 with rats. Rats are not people. It's a little bit 0:07:03.400 --> 0:07:06.520 more complicated with people. Rats don't have as much you know, 0:07:06.560 --> 0:07:10.680 like Buffy reruns to go through, for example, But you 0:07:10.840 --> 0:07:12.200 just set it up so you can be on the 0:07:12.200 --> 0:07:15.680 treadmill and watch the Buffy. That's what I do. I do. 0:07:15.720 --> 0:07:17.240 I turn on things that I want to watch and 0:07:17.280 --> 0:07:19.080 I and I bought around my living room with freeweights. 0:07:19.080 --> 0:07:22.920 That is my basic exercise mode. If you're a wild rat, 0:07:23.000 --> 0:07:26.360 you really need to be getting exercise a lot. I 0:07:26.400 --> 0:07:30.440 would think, right, your choices of your behavior option. Yeah, 0:07:30.680 --> 0:07:33.320 Like there are no cats in America. We were wrong. 0:07:36.640 --> 0:07:39.560 Where are these rats getting their information? I don't know. 0:07:39.760 --> 0:07:42.720 The streets are not, in fact paved with cheese. There 0:07:42.760 --> 0:07:45.000 were no cats in America. We were lied to live. 0:07:45.120 --> 0:07:47.520 I thought they get to be catch potatoes and were wrong. 0:07:47.880 --> 0:07:52.520 It's a secret covert cat operation to misinform rats of 0:07:52.560 --> 0:07:57.640 other countries to come here, go to America. It's awesome. Well, 0:07:57.680 --> 0:08:02.560 unfortunately we've really shut down the the rat population intake 0:08:02.640 --> 0:08:04.840 through Ellis Island. It's really hard to the rat to 0:08:04.880 --> 0:08:09.400 get papers there anymore. Um changes, which is awful. Mousko 0:08:09.520 --> 0:08:15.320 it's anyway, um uh so so so so. Genetics is 0:08:15.320 --> 0:08:18.640 certainly a factor to to not only how good we 0:08:18.720 --> 0:08:21.640 are based level at exercising, but also to whether or 0:08:21.680 --> 0:08:25.160 not we're motivated. But other motivators Again, like we were 0:08:25.160 --> 0:08:27.000 talking about in the in the last episode, is that 0:08:27.040 --> 0:08:30.880 emotional support thing? Um. A meta of you done by 0:08:30.920 --> 0:08:34.440 the Community Preventative Services Task Force of the CDC found 0:08:34.480 --> 0:08:38.360 that social support led to people being physically active in longer, 0:08:38.440 --> 0:08:41.679 more frequent sessions, and that they wound up improving their 0:08:41.720 --> 0:08:46.360 aerobic capacity, confidence and knowledge, and decreasing their body fat percentages. 0:08:46.840 --> 0:08:50.200 So when so, I mean that sounds like basic knowledge, 0:08:50.240 --> 0:08:55.480 but it's a science fact um and uh. Furthermore, a 0:08:55.520 --> 0:08:58.040 series of four studies conducted at the University of Georgia 0:08:58.120 --> 0:09:00.640 here in Town UM published in twenty and found that 0:09:00.679 --> 0:09:05.440 self control, or the lack thereof, is contagious across behaviors um, 0:09:05.480 --> 0:09:07.800 which basically means that if you see people, Joe, you 0:09:07.800 --> 0:09:09.360 were talking about that a little bit in the last 0:09:09.400 --> 0:09:13.200 episode wherein um, you know the that color color effect, 0:09:13.360 --> 0:09:16.840 color effect right where wherein Uh, if you're among a 0:09:16.880 --> 0:09:19.560 group of people performing better than you, it helps you 0:09:20.160 --> 0:09:24.440 sure um And and lots of other research backs this up. 0:09:24.480 --> 0:09:26.800 The Framingham Heart Study, which if you guys have never 0:09:26.840 --> 0:09:30.160 heard about, is my personal favorite medical research study. I 0:09:30.200 --> 0:09:33.880 get super excited about the outcomes from it because, Um, 0:09:33.920 --> 0:09:36.440 this is spanning a community of over fifteen thousand people 0:09:36.480 --> 0:09:40.959 in Massachusetts from on and and so, I mean, all 0:09:40.960 --> 0:09:42.800 of these families living in this one town have just 0:09:42.840 --> 0:09:45.280 been tracked a whole bunch of their weight and health 0:09:45.280 --> 0:09:49.319 indicators forever and and yeah. And there was one segment 0:09:49.320 --> 0:09:53.320 of research that occurred from two thousand three finding that 0:09:53.400 --> 0:09:58.240 obesity and healthy weight both appeared in social clusters. Um 0:09:58.280 --> 0:10:02.000 that that you had an increased at seven percent increased 0:10:02.040 --> 0:10:04.480 chance of becoming obese if you have a friend who 0:10:04.559 --> 0:10:09.800 becomes obest within this time period. That's a lot significant. UM. Yeah, 0:10:09.840 --> 0:10:14.160 way significant, hell is significant. Um. If you're sibling, if 0:10:14.160 --> 0:10:17.040 your adult sibling became abast seven percent, if your spouse 0:10:17.080 --> 0:10:23.360 became abst and so yeah, um so so so that 0:10:23.360 --> 0:10:29.320 that social motivator is really intense, is what I'm saying. Yeah, 0:10:29.400 --> 0:10:32.959 it's amazing that we're still learning these things right, right, 0:10:33.000 --> 0:10:34.559 and that you know, and that it was a it 0:10:34.640 --> 0:10:36.880 was a huge surprise when this research was published. It 0:10:36.920 --> 0:10:40.800 was like, oh, oh dear, oh my goodness. I shouldn't 0:10:40.800 --> 0:10:42.640 have taught that class on how to make mayonnaise, Like, 0:10:42.720 --> 0:10:45.760 you know, you should always teach a class on how 0:10:45.760 --> 0:10:49.160 to make but you all know when mayonnaise was invented. 0:10:49.240 --> 0:10:54.400 I do not. I don't either, but wonder about some 0:10:54.640 --> 0:10:59.559 magical magic somewhere in France long ago. Yeah, so we're 0:10:59.600 --> 0:11:03.400 still learning things like that. Like I Holly told me 0:11:03.440 --> 0:11:09.080 about something that absolutely blew my mind. Apparently the question 0:11:09.200 --> 0:11:12.719 is not settled yet what should you wear when you're running? Well, 0:11:12.720 --> 0:11:17.599 oh it's settled. It is settled by science now. But 0:11:17.679 --> 0:11:20.360 this is a recent thing. Actually, let me correct, lots 0:11:20.400 --> 0:11:23.720 of people don't know, which is shocking to me, but 0:11:23.800 --> 0:11:27.760 only because I crave comfort in all things explained clothes. 0:11:27.800 --> 0:11:30.920 And by the way, Holly explained earlier that she has 0:11:31.679 --> 0:11:35.480 a real love of the history of underwear. So maybe 0:11:35.480 --> 0:11:40.600 this will inform your I don't know that it will, 0:11:40.640 --> 0:11:45.400 except I do have a in history. I really love undergarments. 0:11:45.400 --> 0:11:49.240 I think they're fascinating as an indicator of cultural happenings. 0:11:50.000 --> 0:11:53.320 But in terms of fitness and running specifically, which is 0:11:53.320 --> 0:11:56.200 what I do, a lot of cotton is rotten, and 0:11:56.240 --> 0:11:59.720 there is this thing where people tend to think that 0:11:59.800 --> 0:12:02.360 now tural fibers must be better their natural fibers, for 0:12:02.400 --> 0:12:08.400 heaven's sakes. Um but heads up, not so much when 0:12:08.400 --> 0:12:12.040 you're running, because cotton is very absorbent, but it is 0:12:12.080 --> 0:12:16.040 not so good at drying out. But it comes from 0:12:16.040 --> 0:12:19.280 a plant. How could it be bad? Because if you 0:12:19.400 --> 0:12:22.240 have a wet thing rubbing up against you for thirteen miles, 0:12:23.440 --> 0:12:25.000 I'm going to put a safe bet that it's going 0:12:25.040 --> 0:12:27.400 to start to hurt and become uncomfortable and potentially give 0:12:27.440 --> 0:12:31.600 you a rash. Also, it's making that fabric heavier, which 0:12:31.640 --> 0:12:35.680 is lame. Yes, I scientifically lame. I have taken on 0:12:35.760 --> 0:12:37.400 a lot of water during a run when I was 0:12:37.440 --> 0:12:39.680 wearing a costume, and I could tell you by the 0:12:39.800 --> 0:12:43.199 end of it there was a lot of weight and pain. 0:12:45.760 --> 0:12:53.520 I have a friend on one of his longest runs 0:12:53.600 --> 0:12:56.720 ever that he was sort of forging new territory and 0:12:56.720 --> 0:12:59.840 and he ran a very long run that he had 0:13:00.120 --> 0:13:03.360 done before, and at the end is nipples were not 0:13:03.480 --> 0:13:06.199 in a happy place. I know. That's pretty common. This 0:13:06.320 --> 0:13:07.839 is one of those things that when if you get 0:13:07.880 --> 0:13:12.560 into running, there's this whole secret world of information about 0:13:13.160 --> 0:13:17.720 how that could go horribly wrong. Yeah. And then many 0:13:17.760 --> 0:13:19.720 many kinds of products that are that are sold to 0:13:19.800 --> 0:13:22.760 perhaps lubricate things like your inner thighs and your nipples 0:13:22.800 --> 0:13:24.840 that might get you. Yeah. The big one that most 0:13:24.920 --> 0:13:26.840 runners that I know us is called body glide, and 0:13:26.840 --> 0:13:31.040 it's basically like a uh it looks like a deodorant stick. 0:13:31.120 --> 0:13:34.840 It's like a bomb type thing that will keep things 0:13:34.880 --> 0:13:38.080 from chafing so much. I have heard from friends in 0:13:38.080 --> 0:13:40.280 the military that they just use deodorant. It works exactly 0:13:40.320 --> 0:13:45.040 the same. So okay, test as you will. But the 0:13:45.120 --> 0:13:48.360 thing about textiles and cotton in in particular, is that 0:13:48.520 --> 0:13:50.480 it will As I said, it takes on water, but 0:13:50.559 --> 0:13:52.680 it doesn't it's not very good at getting rid of 0:13:52.720 --> 0:13:54.640 that water, so it's just rubbing up against you and 0:13:54.679 --> 0:13:58.840 causing blisters. If you have cotton socks, um chafing on 0:13:58.920 --> 0:14:01.160 your clothes and so it really has been this huge 0:14:01.160 --> 0:14:05.440 advancement in the last couple of decades in uh what 0:14:05.800 --> 0:14:09.520 is called sort of tech textiles UH and basically they're 0:14:09.600 --> 0:14:11.520 made to wick away water. They pull it off of 0:14:11.520 --> 0:14:14.280 your skin and then it evaporates quickly so you're not 0:14:14.360 --> 0:14:17.560 dragging it around or living in it. This is due 0:14:17.559 --> 0:14:19.840 to the wonder of plastics. It is. It's due to 0:14:19.840 --> 0:14:22.960 the wonder of plastics and of weaving. They're actually woven 0:14:23.480 --> 0:14:27.440 in a way that they will channel water in the 0:14:27.480 --> 0:14:30.480 most dissipating effect, so it keeps water from bulking up 0:14:30.480 --> 0:14:32.840 anywhere on the garment. It will getting a surface area 0:14:32.880 --> 0:14:36.680 great enough to to maximize that evaporation effect. Yeah, there's 0:14:36.720 --> 0:14:40.200 actually like the way that the the we've comes off 0:14:40.200 --> 0:14:42.920 of the loom, and it's usually with polyestro fibers, often 0:14:42.960 --> 0:14:46.720 with nylon involved. They're actually tiny tubes in the textile 0:14:46.760 --> 0:14:51.840 weave that kind of pull water uh away from anyone's spots. 0:14:51.880 --> 0:14:54.560 So it's always on the move. And once you're running 0:14:54.880 --> 0:14:57.840 and that water is getting dissipated into thinner and thinner layers, 0:14:57.880 --> 0:15:02.800 it's evaporating much more quickly. UH. There will often be 0:15:02.840 --> 0:15:06.080 an effect where it's kind of a clear thing to 0:15:06.080 --> 0:15:07.920 test it. So there are two things that are going on. 0:15:07.920 --> 0:15:11.240 One is this this movement of water where they're circulating 0:15:11.240 --> 0:15:14.800 the water away from anyone space. And two is the 0:15:14.800 --> 0:15:17.360 air circulation around you that's bringing it off, so that 0:15:17.440 --> 0:15:20.840 as you're running normally, you're creating wind currents around yourself 0:15:21.440 --> 0:15:23.640 and that's helping. But if you ever want to test 0:15:23.720 --> 0:15:27.120 like this actually functioning with and without the wind portion 0:15:27.200 --> 0:15:29.600 of it, uh, if you run in a small room 0:15:29.600 --> 0:15:31.600 on a treadmill, you are not going to dry off 0:15:31.600 --> 0:15:34.480 as quickly because there's just not as much air movement 0:15:34.480 --> 0:15:35.880 around you, whereas if you go outside and do the 0:15:35.920 --> 0:15:38.400 exact same run in the exact same temperature, in the 0:15:38.440 --> 0:15:42.840 same wicking garment, you will be dry much more quickly. Uh. 0:15:42.880 --> 0:15:46.240 And those will help keep you from getting horrible chafing misery. 0:15:46.760 --> 0:15:49.320 It helps with the nipple thing that boys get sometimes 0:15:49.680 --> 0:15:55.680 women usually are wearing sports bra so it's there. There's 0:15:55.720 --> 0:15:59.280 a whole other set of physics work there. Um. But yeah, 0:15:59.280 --> 0:16:02.880 and the textile industry is constantly sort of working to 0:16:03.040 --> 0:16:06.880 keep these uh, these fabrics advancing and getting better and 0:16:06.920 --> 0:16:09.520 better at their jobs. And some will keep you warm 0:16:09.560 --> 0:16:12.200 and cold climates and others will keep you cool in 0:16:12.240 --> 0:16:16.840 hot climates. UM. It's very fascinating and good stuff. The 0:16:17.200 --> 0:16:18.760 some of the stuff I'm excited about, I think I 0:16:18.800 --> 0:16:20.680 think that you edited an article about this fair how 0:16:20.720 --> 0:16:25.040 stuff works, Holly was UM people who are integrating some 0:16:25.160 --> 0:16:31.200 of the UH bio sensors into garments like this and 0:16:31.200 --> 0:16:33.320 and using so that you can wear a shirt that 0:16:33.360 --> 0:16:37.119 will a wick your moisture away and be track your activity. 0:16:37.520 --> 0:16:40.280 Is that there are some there are experimental. There's nothing 0:16:40.320 --> 0:16:44.320 on the market UM for anybody that watches Project Runway. 0:16:44.360 --> 0:16:46.960 Many seasons back, there was a designer named Diana Ang 0:16:47.040 --> 0:16:49.600 and she's actually from a science background and she's done 0:16:49.600 --> 0:16:53.600 a lot of really interesting stuff working with UM various 0:16:53.640 --> 0:16:58.160 sensors and technologies. She worked on a hoodie some years 0:16:58.160 --> 0:17:00.440 back that had a camera in it that was in 0:17:00.520 --> 0:17:02.480 the top of the hood so if you're wearing the hoodie, 0:17:02.760 --> 0:17:05.000 there was a heart monitor attached and when your heart 0:17:05.080 --> 0:17:07.840 elevated past a certain rate, it would automatically take a picture. 0:17:08.280 --> 0:17:11.560 And her idea was one of an artistic concept of like, 0:17:11.640 --> 0:17:13.679 when you are excited, it will be taking a record 0:17:13.680 --> 0:17:16.000 of the things that excite you in your life. UH. 0:17:16.040 --> 0:17:19.000 There are potential military applications to it that I think 0:17:19.040 --> 0:17:22.600 have been kind of investigated. I remember when it first 0:17:22.640 --> 0:17:26.080 came out, there was talk on various um kind of 0:17:26.119 --> 0:17:30.639 nerdy textile message boards about the potential um application of 0:17:30.680 --> 0:17:33.760 having people that were, for example, on parole, wearing something 0:17:33.800 --> 0:17:35.440 like this so that if it looked like they were 0:17:35.480 --> 0:17:40.000 likely to um knock over once again, like go into 0:17:40.000 --> 0:17:42.639 a life of crime, theoretically their heart would rise and 0:17:42.680 --> 0:17:49.960 it would do it. But textile message boards, there's everything 0:17:50.040 --> 0:17:53.159 and anything you could ever imagine on the Internet in 0:17:53.240 --> 0:17:56.200 message board form. I was going to say, is another 0:17:56.240 --> 0:17:58.840 quick aside that some of this technology, and I think 0:17:58.880 --> 0:18:03.000 this is on the market in Japan or Korea, that 0:18:03.080 --> 0:18:06.600 there are ears and tails that they sell that have 0:18:06.760 --> 0:18:11.040 little little little mini rots and then that will will here, okay, 0:18:11.040 --> 0:18:12.800 that will react to your heart rate when when you 0:18:12.800 --> 0:18:15.360 get excited your your tail awag or whatever. You can't 0:18:15.440 --> 0:18:18.840 they have them some anime conventions you'll find them. So, 0:18:19.320 --> 0:18:21.560 but that is getting away from that's like a fun, 0:18:21.640 --> 0:18:23.960 fun thing, right, But from the fitness angle, it's a 0:18:24.040 --> 0:18:27.160 very short walk to envision things like that being integrated 0:18:27.200 --> 0:18:30.480 into your clothes to kind of track how you're doing 0:18:30.520 --> 0:18:32.840 in your health that you're doing it in your performance. 0:18:33.720 --> 0:18:36.520 And they're even clothes that are allegedly designed to keep 0:18:36.520 --> 0:18:39.960 you warm enough that your basil metabolic rate increases. It's 0:18:39.960 --> 0:18:43.359 like that you're burning more, more calories faster at all times, 0:18:43.400 --> 0:18:46.400 even when you're still I haven't tested them. I don't 0:18:46.400 --> 0:18:49.400 know some some some of those we're going to get 0:18:49.400 --> 0:18:51.600 in in a minute into some of the kind of 0:18:52.320 --> 0:18:54.440 what I could do, waste of money sort of things 0:18:54.520 --> 0:18:59.080 that I'm going to talk about bad exercise science too, 0:18:59.240 --> 0:19:01.879 and that that that sounds like it's arranging very dangerously 0:19:01.920 --> 0:19:06.359 close to. But I want to talk about another issue 0:19:06.400 --> 0:19:09.040 I've heard about, and this is funny because people have 0:19:09.240 --> 0:19:12.840 opinions about this one well, about everything related to fitness. 0:19:14.359 --> 0:19:18.159 There is apparently some debate between people who favor running 0:19:18.280 --> 0:19:23.320 with shoes on versus people who favor running barefoot. Christopher McDougal, 0:19:23.440 --> 0:19:25.480 what have you done to us? I I believe. I 0:19:25.520 --> 0:19:28.080 believe that if all tell me the science facts, all 0:19:28.320 --> 0:19:31.040 the terrible understatements that we make on this show, that 0:19:31.200 --> 0:19:33.960 is maybe one that I'm the most personally familiar with 0:19:34.119 --> 0:19:36.880 and terrified by. I don't even like saying the word 0:19:36.960 --> 0:19:40.000 barefoot on the internet anymore. It's like saying Nazis. It's 0:19:40.080 --> 0:19:42.480 just it's awful. I mean people get up in arms, 0:19:42.680 --> 0:19:47.600 Um they do so. So so how are you're you're 0:19:47.600 --> 0:19:50.520 you're entrenched in running communities? Do do you do? You 0:19:50.560 --> 0:19:54.080 have a personal recollection of when this whole thing got started? 0:19:54.119 --> 0:19:57.920 And uh yeah, I mean when it really exploded was 0:19:57.960 --> 0:20:00.520 when Christopher McDougal's book, which is called And to Run, 0:20:00.640 --> 0:20:03.560 came out and in it it is a book that's 0:20:03.600 --> 0:20:07.280 about running but also about cultural anthropology, and in it 0:20:07.320 --> 0:20:11.360 he talks about the Tatahumara tribe of Mexico and they 0:20:11.400 --> 0:20:15.440 are just culturally runners. They run four hundreds of miles 0:20:15.440 --> 0:20:17.600 at a time wearing nothing but like basically a piece 0:20:17.640 --> 0:20:20.359 of leather strap to the bottom of their foot. And 0:20:20.440 --> 0:20:22.919 this sort of launched this big discussion about how no, 0:20:23.080 --> 0:20:28.960 our bodies are actually designed biomechanically, with without big crazy 0:20:29.600 --> 0:20:33.880 shoes made in a factory. You were made unner, made 0:20:33.920 --> 0:20:35.439 to be a runner, and so this must be the 0:20:35.520 --> 0:20:38.440 right way. These people run all the time, they're injury free, 0:20:38.880 --> 0:20:43.280 they must be doing it correctly. This started this huge 0:20:43.720 --> 0:20:47.399 movement where people were like, I'm throwing out my shoes. Um. 0:20:47.480 --> 0:20:50.520 I mean I personally have a brother of a close 0:20:50.520 --> 0:20:52.600 friend of mine who is an ultramarrathon or he will 0:20:52.640 --> 0:20:56.480 do hundred mile races and this is a great idea, 0:20:56.600 --> 0:20:58.840 and he ran out and ran like twenty two miles 0:20:58.840 --> 0:21:02.320 and got a stress fracture because his body. While bio 0:21:02.320 --> 0:21:05.119 mechanically we may be designed to do that on some level. 0:21:05.520 --> 0:21:07.560 If your whole life has not been spent that way 0:21:07.600 --> 0:21:09.720 and then you start running that way, that's not what 0:21:09.760 --> 0:21:14.640 your body does anymore, right, sold, just as an outside observer, 0:21:15.040 --> 0:21:19.040 I mean on that that evolutionary adaptation argument. I mean, 0:21:19.240 --> 0:21:22.520 they're all kinds of states of nature in which we 0:21:22.640 --> 0:21:26.720 are evolved to do certain things. But certainly we're healthier 0:21:26.720 --> 0:21:30.200 if we do them a different way or or or 0:21:30.240 --> 0:21:32.560 at least more comfortable, or it's what we're used to. 0:21:32.640 --> 0:21:34.080 And I think that what we're used to is a 0:21:34.160 --> 0:21:37.120 larger factor most of the time. I mean, okay, So, 0:21:37.119 --> 0:21:40.679 so the the actual biomedical end of this is is 0:21:40.720 --> 0:21:43.960 that people who push for barefoot running say that it's 0:21:44.680 --> 0:21:46.680 that the most efficient way to run is to land 0:21:46.680 --> 0:21:49.159 on the fore foot or slightly into the midfoot rum. 0:21:49.320 --> 0:21:53.199 Rather than he'll striking, he'll striking being Um what a 0:21:53.240 --> 0:21:56.160 lot of these very padded shoes that became especially popular 0:21:56.400 --> 0:21:58.639 in the nine eighties, and they really didn't become popular 0:21:58.840 --> 0:22:02.040 until the nineteen eighties. Things like checks uh Converse were 0:22:02.200 --> 0:22:05.960 very popular as actual exercise shoes through the nineteen seventies. 0:22:06.000 --> 0:22:09.480 Those really were for basketball, right, like heavy impact activity 0:22:09.600 --> 0:22:11.640 and not for hipsters like me. Right yeah, I mean 0:22:11.760 --> 0:22:13.320 they didn't wear them to the office or I mean, 0:22:13.320 --> 0:22:15.520 I guess they could have. But wearing them right now, 0:22:15.560 --> 0:22:20.160 I am. I mean they're great, they're super comfortable, but 0:22:20.400 --> 0:22:23.040 um but I cannot imagine running in them. I do 0:22:23.080 --> 0:22:25.840
