Well, once the ments are gone, 5 00:00:18,520 --> 00:00:20,920 Speaker 1: you can do some really neat things with the leftover tense. 6 00:00:21,320 --> 00:00:25,200 Speaker 1: People have made empty three players, cameras, even stoves. Check 7 00:00:25,200 --> 00:00:27,720 Speaker 1: out how stuff works dot com slash tent evators to 8 00:00:27,800 --> 00:00:33,120 Speaker 1: find out more. Hey, and welcome to the podcast. I'm 9 00:00:33,240 --> 00:00:36,839 Speaker 1: Josh Clark. With me is always as Charles Bryant. I 10 00:00:36,880 --> 00:00:39,280 Speaker 1: don't even know why I say that. Chuck. I should 11 00:00:39,280 --> 00:00:41,919 Speaker 1: just go Josh and Chuck here, you get your thing. 12 00:00:42,240 --> 00:00:44,720 Speaker 1: This is a stupid intro. Chuck, let's start over. You 13 00:00:44,720 --> 00:00:48,000 Speaker 1: say that every week. Hey, and welcome to the podcast. 14 00:00:48,080 --> 00:00:50,920 Speaker 1: I'm Josh Clark. There's Chuck Bryant. This is stuff you 15 00:00:50,920 --> 00:00:54,640 Speaker 1: should know. Thanks for listening to us. Thank you, and 16 00:00:54,760 --> 00:00:57,000 Speaker 1: even hardier things would go out if people actually paid 17 00:00:57,040 --> 00:01:00,960 Speaker 1: for this. But still no, people like free Yeah, good 18 00:01:00,960 --> 00:01:03,240 Speaker 1: for them. Well yeah, well we're not charging for it. 19 00:01:03,760 --> 00:01:06,200 Speaker 1: If you're not. Everyone, I'm just saying right, and you 20 00:01:06,240 --> 00:01:08,319 Speaker 1: know what, think about that before you write in and 21 00:01:08,319 --> 00:01:11,560 Speaker 1: tell us. We're idiots. Yeah, we'll give you your money back. 22 00:01:11,760 --> 00:01:14,000 Speaker 1: Did you ever see that Simpsons where Bart goes off 23 00:01:14,040 --> 00:01:18,600 Speaker 1: on um that itchy and scratchy fan. No, where he's 24 00:01:18,600 --> 00:01:20,840 Speaker 1: actually talking about the Simpsons the guys like, I feel 25 00:01:20,880 --> 00:01:22,720 Speaker 1: like they owe me something as a loyal fan. I 26 00:01:22,720 --> 00:01:24,640 Speaker 1: think it was Comic book guy. He goes off on 27 00:01:25,560 --> 00:01:27,520 Speaker 1: and he goes, oh, really, they owe you something for 28 00:01:27,920 --> 00:01:32,120 Speaker 1: years and years of free programming entertainment that they provided 29 00:01:32,120 --> 00:01:34,559 Speaker 1: you no charge. That's what happens. Though. You know, people 30 00:01:34,600 --> 00:01:36,360 Speaker 1: will take ownership and I do the same thing. We 31 00:01:36,400 --> 00:01:39,839 Speaker 1: all do. It's nice to be owned. It's like lost sucks. Now, 32 00:01:39,880 --> 00:01:42,160 Speaker 1: how could you do that doesn't suck? I've never paid 33 00:01:42,200 --> 00:01:44,759 Speaker 1: any attention to it. Actually, I think this past season 34 00:01:44,920 --> 00:01:46,440 Speaker 1: was a return to for him, but the previous season 35 00:01:46,520 --> 00:01:50,720 Speaker 1: was a little lame. It happens. Moving on, moving on 36 00:01:50,760 --> 00:01:56,520 Speaker 1: to Sarcopenia. Well, speaking of aging aging television shows, yes, 37 00:01:57,400 --> 00:02:01,240 Speaker 1: we could also discuss aging human beings. Very nice, Josh, 38 00:02:01,840 --> 00:02:05,280 Speaker 1: that was that was clumsy? That got delivered by a 39 00:02:05,360 --> 00:02:08,960 Speaker 1: drunk pizza guy. Let's dish on Sarcopenia. I just like 40 00:02:09,040 --> 00:02:12,000 Speaker 1: that name. It's it's a good name. It is um 41 00:02:12,120 --> 00:02:15,320 Speaker 1: so Chuck. You know, there's some obvious signs of aging 42 00:02:15,720 --> 00:02:20,040 Speaker 1: as as we progress in our years. Especially it seems 43 00:02:20,080 --> 00:02:22,000 Speaker 1: like these days, once you start to hit the mid 44 00:02:22,080 --> 00:02:24,880 Speaker 1: to late seventies, all of a sudden, bam, you're like 45 00:02:24,960 --> 00:02:29,480 Speaker 1: half your height, stooped over, your rib cage is sunken 46 00:02:29,480 --> 00:02:34,640 Speaker 1: in like the guy from the Unforgiven Metallica video, sagging skin. 47 00:02:34,880 --> 00:02:38,639 Speaker 1: These are the signs of age, and you just kind 48 00:02:38,680 --> 00:02:40,520 Speaker 1: of take this for granted. I know I did until 49 00:02:40,520 --> 00:02:43,160 Speaker 1: I wrote this article. But it turns out that a 50 00:02:43,160 --> 00:02:46,160 Speaker 1: lot of this stuff can be prevented. And a lot 51 00:02:46,200 --> 00:02:50,080 Speaker 1: of these signs of aging are sarcopenia, which is age 52 00:02:50,080 --> 00:02:53,000 Speaker 1: related muscle loss. Right, And we just want to say 53 00:02:53,040 --> 00:02:56,240 Speaker 1: out there, if you are under forty, like many of 54 00:02:56,240 --> 00:02:59,960 Speaker 1: our listeners probably are, listen up because it will happen 55 00:03:00,080 --> 00:03:03,600 Speaker 1: YouTube and you can remember this one day and and 56 00:03:03,720 --> 00:03:07,280 Speaker 1: use it, or you can advise your parents and grandparents. Yeah. Well, 57 00:03:07,320 --> 00:03:09,600 Speaker 1: actually the whole reason this came up was because I 58 00:03:09,639 --> 00:03:12,800 Speaker 1: was talking to my dad about it. He just turned 59 00:03:12,840 --> 00:03:16,720 Speaker 1: seventy one and July four and um, he's starting to 60 00:03:16,919 --> 00:03:19,600 Speaker 1: he lost a bunch of weight. He's looking like Mr 61 00:03:19,680 --> 00:03:25,600 Speaker 1: Burt Reynolds these days. Um, a lot. Actually only mac though, 62 00:03:25,639 --> 00:03:28,880 Speaker 1: only the good stuff. Um. And he's but he's his 63 00:03:28,960 --> 00:03:31,040 Speaker 1: muscles are starting to actually because he's losing a bunch 64 00:03:31,040 --> 00:03:33,960 Speaker 1: of weight and he's advancing in age, but he's not 65 00:03:34,000 --> 00:03:36,880 Speaker 1: exercising as much. So I said, you know what, You're 66 00:03:36,920 --> 00:03:39,200 Speaker 1: at risk for sarcopania. And I'm going to look up 67 00:03:39,200 --> 00:03:41,760 Speaker 1: this article I wrote. And you were sitting next to me, 68 00:03:41,800 --> 00:03:43,880 Speaker 1: and you said, are we podcasting on that this week? 69 00:03:43,920 --> 00:03:46,280 Speaker 1: And I said, yes, we are, so here we are everyone. 70 00:03:46,440 --> 00:03:48,720 Speaker 1: That's how it happens to the back story. People always 71 00:03:48,760 --> 00:03:51,080 Speaker 1: wonder how we pick. That's how we pick sometimes. Yeah, 72 00:03:51,080 --> 00:03:53,520 Speaker 1: and the whole reason. Um, also because we do have 73 00:03:53,880 --> 00:03:58,520 Speaker 1: a fairly young listener ship. This can be prevented most 74 00:03:58,520 --> 00:04:02,840 Speaker 1: easily by starting. Yeah, starting you. So let's talk about sarcopane. 75 00:04:02,920 --> 00:04:09,119 Speaker 1: Let's talk about muscle loss first. Let's talk about muscle chuck. Protein. Yeah, yes, 76 00:04:09,240 --> 00:04:13,280 Speaker 1: muscle mass is protein basically the end, the end. And uh, 77 00:04:13,400 --> 00:04:15,800 Speaker 1: I like your how you said that in the article 78 00:04:15,880 --> 00:04:19,359 Speaker 1: that the body seeks stasis. So what you want is 79 00:04:19,400 --> 00:04:22,600 Speaker 1: that balance between the production and usage of that protein, right, 80 00:04:22,640 --> 00:04:25,039 Speaker 1: you don't want to overproduce. The body seeks stasis in 81 00:04:25,080 --> 00:04:28,520 Speaker 1: many many ways. Well, yeah, that's that's the that's the yeah, 82 00:04:28,800 --> 00:04:33,480 Speaker 1: that's that's the level that it's it's seeking at all 83 00:04:33,560 --> 00:04:37,320 Speaker 1: times with everything right, equilibrium, equilibrium body. It's a beautiful thing. 84 00:04:37,560 --> 00:04:41,360 Speaker 1: So chuck, um, muscle is obviously produced in the body. 85 00:04:41,640 --> 00:04:44,000 Speaker 1: We don't just you know, go buy a length of 86 00:04:44,080 --> 00:04:46,600 Speaker 1: muscle and insert it where we want it one day. 87 00:04:46,760 --> 00:04:51,000 Speaker 1: Yeah right yeah, um. We we actually can produce our 88 00:04:51,040 --> 00:04:54,680 Speaker 1: own um through non essential proteins. These are proteins that 89 00:04:54,720 --> 00:04:58,680 Speaker 1: the body produces its on its own. Right. Then we 90 00:04:58,839 --> 00:05:02,200 Speaker 1: have essential protein that we need to build muscle, and 91 00:05:02,440 --> 00:05:05,880 Speaker 1: we derived these by you know, jumping on gazelles and 92 00:05:05,920 --> 00:05:09,480 Speaker 1: eating their throats out, or just eating peanut butter and 93 00:05:09,520 --> 00:05:11,839 Speaker 1: things like that to contain on protein, tuna, tearing the 94 00:05:11,880 --> 00:05:14,400 Speaker 1: throat out of peanut butter. So we gotta tear the 95 00:05:14,400 --> 00:05:16,440 Speaker 1: throat of something to get muscle, right, and those are 96 00:05:16,480 --> 00:05:20,040 Speaker 1: essential proteins. You're right, right, you might have already said that. 97 00:05:20,240 --> 00:05:22,960 Speaker 1: I think I did, but it doesn't matter, buddy. Um. 98 00:05:23,000 --> 00:05:25,599 Speaker 1: So we take this protein, uh and and the stuff 99 00:05:25,640 --> 00:05:28,719 Speaker 1: we produce it's called synthesis, and the stuff we use 100 00:05:28,800 --> 00:05:33,800 Speaker 1: the not the essential proteins, that's metabolism. Right, um, And 101 00:05:33,920 --> 00:05:37,600 Speaker 1: we we never really lose our ability to metabolize proteins 102 00:05:38,000 --> 00:05:41,720 Speaker 1: as we age, but we do tend to lose our 103 00:05:41,760 --> 00:05:45,279 Speaker 1: ability to synthesize our own right. This is where you 104 00:05:45,279 --> 00:05:48,520 Speaker 1: wanted to get into hormones. Correct, you were just setting 105 00:05:48,520 --> 00:05:52,159 Speaker 1: me up all day long, buddy. Uh. Insulin like growth 106 00:05:52,240 --> 00:05:57,039 Speaker 1: hormone I g F one. Yeah, testosterone and growth hormone, 107 00:05:57,360 --> 00:06:00,400 Speaker 1: they all play a role in the product and of 108 00:06:00,800 --> 00:06:03,279 Speaker 1: the protein. Josh, did you know that I did? I 109 00:06:03,320 --> 00:06:07,520 Speaker 1: wrote this article. Well anyway, the point is these hormones, hormones, 110 00:06:07,560 --> 00:06:11,400 Speaker 1: you know, are the chemical messengers in our body. They 111 00:06:11,400 --> 00:06:13,920 Speaker 1: do all sorts of crazy stuff. I just wrote about, um, 112 00:06:13,920 --> 00:06:16,400 Speaker 1: whether or not you can get pregnant while you're breastfeeding. 113 00:06:16,920 --> 00:06:19,360 Speaker 1: And hormones are amazing. And by the way, I know 114 00:06:19,480 --> 00:06:22,520 Speaker 1: everything there is to know about the about the menstrual cycle. 115 00:06:22,839 --> 00:06:26,080 Speaker 1: You know everything. I'll ask me any question later, I'll 116 00:06:26,120 --> 00:06:30,600 Speaker 1: tell you many minarchy. The problem, Josh, is that the 117 00:06:31,440 --> 00:06:34,640 Speaker 1: pro these hormones decline as we age, right, So the 118 00:06:34,640 --> 00:06:38,440 Speaker 1: the the um the protein production is aren't getting it's 119 00:06:38,480 --> 00:06:41,960 Speaker 1: not getting the signals that it used to through the hormone, 120 00:06:42,000 --> 00:06:46,120 Speaker 1: so non essential protein production slips leaving only essential production 121 00:06:46,880 --> 00:06:49,960 Speaker 1: or I'm sorry, essential proteins that you ingest. And I 122 00:06:50,000 --> 00:06:52,560 Speaker 1: think you you indicated that as we get older, we 123 00:06:52,560 --> 00:06:54,440 Speaker 1: actually need more proteins. So that's kind of like a 124 00:06:54,480 --> 00:06:56,920 Speaker 1: one to punch, right, and we don't necessarily get more 125 00:06:56,960 --> 00:07:00,760 Speaker 1: proteins once you Once you establish a diet in your lifetime, 126 00:07:01,200 --> 00:07:03,760 Speaker 1: you usually kind of stick to it, especially in your 127 00:07:03,760 --> 00:07:06,440 Speaker 1: seventies and right. I mean people may you know, kind 128 00:07:06,440 --> 00:07:10,000 Speaker 1: of come to understand their bodies. I can't remember how 129 00:07:10,040 --> 00:07:12,680 Speaker 1: Douglas Copeland put it in. Generates an X, I think 130 00:07:12,720 --> 00:07:15,760 Speaker 1: aware of your body. People become aware of their bodies 131 00:07:16,040 --> 00:07:18,440 Speaker 1: later in life, so they may change their diet some 132 00:07:18,640 --> 00:07:22,040 Speaker 1: but generally, you're your protein intake will remain the same 133 00:07:22,080 --> 00:07:24,960 Speaker 1: even though you need it more. So you've got hormone 134 00:07:25,000 --> 00:07:29,400 Speaker 1: decline and protein deficiency. So that's two of the three. 135 00:07:29,440 --> 00:07:31,840 Speaker 1: Actually we didn't even mention the third yet. Well this 136 00:07:31,880 --> 00:07:33,840 Speaker 1: is the most this is the most vital one motor 137 00:07:33,920 --> 00:07:37,680 Speaker 1: unit restructuring. So you've got these three things, hormone decline, 138 00:07:37,680 --> 00:07:41,360 Speaker 1: protein deficiency, and motor unit um restructuring, which we were 139 00:07:41,360 --> 00:07:43,560 Speaker 1: about to get into, and all of a sudden, you've 140 00:07:43,600 --> 00:07:47,800 Speaker 1: got sarcopenia because you're stooped over. Your face is sagging again. 141 00:07:47,840 --> 00:07:50,720 Speaker 1: You look like the old guy from the Unforgiven video. 142 00:07:50,960 --> 00:07:54,720 Speaker 1: You're walking slow. What is the Unforgiven video? You know 143 00:07:54,760 --> 00:08:01,240 Speaker 1: that Metallica song Unforgiven. It came out post Good Metallica, 144 00:08:02,040 --> 00:08:07,000 Speaker 1: before Horrible Metallica. So it was during the after Ride, 145 00:08:07,000 --> 00:08:12,600 Speaker 1: the Lightning before whatever, that Lala Pellusa tour when they 146 00:08:12,600 --> 00:08:15,600 Speaker 1: started wearing eyeliner and stuff, when they cut their hair. 147 00:08:16,040 --> 00:08:19,160 Speaker 1: So we've got we've got sarcopenia um, but we haven't 148 00:08:19,160 --> 00:08:21,880 Speaker 1: really talked about that motor unit restructuring. This is the 149 00:08:21,920 --> 00:08:25,920 Speaker 1: most important factor, right, So let me tell them what 150 00:08:25,920 --> 00:08:29,960 Speaker 1: a motor unit is. Yes, So, Joshua, things called motor neurons, 151 00:08:30,000 --> 00:08:34,120 Speaker 1: and they command the muscle fibers to voluntary muscle fibers 152 00:08:34,160 --> 00:08:37,280 Speaker 1: voluntary muscifibers to do things. Right, So that's a motor 153 00:08:37,360 --> 00:08:39,920 Speaker 1: unit as those two things together, right, the muscle fibers 154 00:08:39,920 --> 00:08:43,640 Speaker 1: they command, and the neurons the muscle fibers and the 155 00:08:43,679 --> 00:08:46,520 Speaker 1: neurons that command them. That's a motor unit, right. And 156 00:08:46,520 --> 00:08:50,080 Speaker 1: and again it's strictly voluntary muscle we're talking about. So 157 00:08:50,120 --> 00:08:52,640 Speaker 1: the neuron gets a command from the brain. I think. 158 00:08:52,640 --> 00:08:54,560 Speaker 1: In the article I used the example of raised right 159 00:08:54,720 --> 00:08:57,240 Speaker 1: arm and punch chuck in the neck. I would never 160 00:08:57,280 --> 00:09:01,160 Speaker 1: do that. I'd say, shut up, brain. Um. So the 161 00:09:01,240 --> 00:09:04,320 Speaker 1: brain sends the signal to the neurons involved in raising 162 00:09:04,320 --> 00:09:10,479 Speaker 1: your right arm and they fire um and contract the muscles. Innervation, 163 00:09:10,559 --> 00:09:12,520 Speaker 1: which is what's going on, like you're lifting your arm. 164 00:09:12,640 --> 00:09:15,640 Speaker 1: It's really a bunch of muscles contracting. And when I 165 00:09:15,679 --> 00:09:17,520 Speaker 1: think about it like that, I think about like little 166 00:09:17,559 --> 00:09:22,960 Speaker 1: tiny like pirates, like pulling on the um, the hoisting, 167 00:09:22,960 --> 00:09:26,680 Speaker 1: the sale sure like that like he ho he, and 168 00:09:26,679 --> 00:09:29,760 Speaker 1: all of a sudden, your your your arm is raised. 169 00:09:29,960 --> 00:09:32,840 Speaker 1: Right there. You have it. It's called innervation. Technically, when 170 00:09:32,920 --> 00:09:35,240 Speaker 1: the muscle fibers are caused to contract from the neurons 171 00:09:35,360 --> 00:09:38,880 Speaker 1: right um, now raising your arm, that would be pretty 172 00:09:38,960 --> 00:09:43,880 Speaker 1: much probably exclusively the result of slow twitch neurons. Yeah, 173 00:09:43,960 --> 00:09:45,920 Speaker 1: lets we need to explain the difference here. There's two 174 00:09:45,960 --> 00:09:49,480 Speaker 1: kinds of neurons. There's fast twitch and they're slow twitch 175 00:09:49,960 --> 00:09:55,760 Speaker 1: ft and st and fast hitch fast twitch fast twitch fastitch. 176 00:09:56,160 --> 00:09:59,280 Speaker 1: I like fast twitch fast twitch. That's really hard to say. 177 00:09:59,720 --> 00:10:03,839 Speaker 1: Is it's like Irish wristwatch? Yeah, exactly. It's very specialized 178 00:10:03,840 --> 00:10:08,240 Speaker 1: because they command like only fast movements like when you run, 179 00:10:08,360 --> 00:10:11,800 Speaker 1: or like eye twitches your eyelids. Yeah, like really precise movement. 180 00:10:11,920 --> 00:10:13,760 Speaker 1: But there aren't as many of them because they only 181 00:10:13,800 --> 00:10:17,000 Speaker 1: command a certain you know, limited number of functions. Right. Well, 182 00:10:17,040 --> 00:10:20,400 Speaker 1: one one fast twitch neuron will command, um, say, just 183 00:10:20,480 --> 00:10:23,120 Speaker 1: a few muscle fibers because it has to be precise, 184 00:10:23,559 --> 00:10:25,840 Speaker 1: so it can't be concerned with a whole bunch at once. 185 00:10:26,120 --> 00:10:29,080 Speaker 1: Slight twitch, on the other hand, is uh the mass. 186 00:10:30,080 --> 00:10:32,440 Speaker 1: I think the way I put it in the article was, um, 187 00:10:32,679 --> 00:10:36,440 Speaker 1: the fast twitch neurons are kind of agile, like a 188 00:10:36,520 --> 00:10:40,520 Speaker 1: tightrope walker, where slow twitch or like bulls and China shops, 189 00:10:40,840 --> 00:10:43,640 Speaker 1: they're just kind of big and dumb and lumbering and brewer, 190 00:10:43,880 --> 00:10:46,400 Speaker 1: you know exactly. So the slow twitch neuron is going 191 00:10:46,440 --> 00:10:49,640 Speaker 1: to raise your arm because it's just a bunch of 192 00:10:51,240 --> 00:10:56,360 Speaker 1: just muscle fiber that isn't really involved in anything precise. Big. 193 00:10:56,840 --> 00:11:00,439 Speaker 1: The problem is that the ft the fast twitch, they 194 00:11:00,480 --> 00:11:04,040 Speaker 1: die off as you age, first the first to go. 195 00:11:04,480 --> 00:11:07,400 Speaker 1: So what happens is if if there if if a 196 00:11:07,400 --> 00:11:10,880 Speaker 1: group of muscle fibers are no longer commanded by a neuron, 197 00:11:11,520 --> 00:11:16,680 Speaker 1: they're at risk of um atrophying, right, which is muscle death. Right. 198 00:11:17,080 --> 00:11:18,800 Speaker 1: Uh so then all of a sudden you have muscle 199 00:11:18,840 --> 00:11:22,520 Speaker 1: loss to prevent this body has a pretty cool system. 200 00:11:22,600 --> 00:11:26,239 Speaker 1: This is very cool. Out of nowhere, Um, the closest 201 00:11:26,320 --> 00:11:30,480 Speaker 1: slow twitch neuron that's that's uh, the one that's closest 202 00:11:30,520 --> 00:11:34,000 Speaker 1: to the dead fast twitch neuron will take over, will 203 00:11:34,040 --> 00:11:38,240 Speaker 1: attach itself and take command in place of right. Yes, 204 00:11:38,640 --> 00:11:41,320 Speaker 1: so you still need these precise movements, but now it's 205 00:11:41,400 --> 00:11:47,680 Speaker 1: being um, they're being commanded by a big, dumb, lumbering neuron. Right. 206 00:11:47,720 --> 00:11:51,200 Speaker 1: So that is the restructuring. That's motor motor unit restructuring, right, 207 00:11:51,200 --> 00:11:53,240 Speaker 1: And the result of it is UM. You know if 208 00:11:53,559 --> 00:11:57,960 Speaker 1: a loss of coordination, UM, a loss of quick reaction, yes, 209 00:11:58,040 --> 00:12:01,600 Speaker 1: less precise right, So that's part of that UM, that 210 00:12:01,760 --> 00:12:04,240 Speaker 1: lack of balance that happens as you age. It's actually 211 00:12:04,320 --> 00:12:07,080 Speaker 1: the result of muscle loss, exactly. And that's part three 212 00:12:07,800 --> 00:12:10,240 Speaker 1: of the what you called the perfect storm that can 213 00:12:10,720 --> 00:12:14,000 Speaker 1: increase the onset of sarcopania. And when this happens, especially 214 00:12:14,040 --> 00:12:16,640 Speaker 1: along the spine, the muscle fibers along the spine, when 215 00:12:16,640 --> 00:12:22,280 Speaker 1: there's motor unit restructuring or just straight up neuron death, UM, 216 00:12:22,360 --> 00:12:24,680 Speaker 1: that's that's what gives us our stoop posture because the 217 00:12:24,720 --> 00:12:29,920 Speaker 1: stand upright, it requires muscles going he hoped right, and um, 218 00:12:30,000 --> 00:12:32,200 Speaker 1: when you lose it, you end up being stooped over. 219 00:12:32,559 --> 00:12:35,280 Speaker 1: So these all put together, all these signs of age, 220 00:12:35,320 --> 00:12:39,160 Speaker 1: the loss of the intercostal muscles between the ribs, stoop postures, 221 00:12:39,200 --> 00:12:42,560 Speaker 1: sagging skin, it's called senile sarcopania. And this is the 222 00:12:42,559 --> 00:12:46,240 Speaker 1: most preventable type of sarcopania. You can also get sarcopania 223 00:12:46,320 --> 00:12:50,680 Speaker 1: from um disease. There's some other much less preventable forms 224 00:12:50,679 --> 00:12:55,600 Speaker 1: of environmental conditions can sure Like basically, if you lay 225 00:12:55,640 --> 00:13:00,440 Speaker 1: down in a highway tunnel for several years and just 226 00:13:00,480 --> 00:13:05,160 Speaker 1: inhale carbon monoxide constantly, you're probably sarcopenia will be among 227 00:13:05,240 --> 00:13:08,199 Speaker 1: the various maladies that developed. Well, the good news though, 228 00:13:08,240 --> 00:13:09,920 Speaker 1: like you said, is that this can be prevented, and 229 00:13:09,960 --> 00:13:12,760 Speaker 1: this is the message that you need to talk to 230 00:13:12,800 --> 00:13:15,360 Speaker 1: your parents and grandparents about and what people like me 231 00:13:15,559 --> 00:13:18,320 Speaker 1: need to remember very soon as I am aging right, 232 00:13:18,360 --> 00:13:23,840 Speaker 1: And there's an easy solution to this waights resistance training. 233 00:13:24,360 --> 00:13:27,199 Speaker 1: So for a long time doctors well they still do, 234 00:13:27,640 --> 00:13:31,359 Speaker 1: but physicians UM have The medical establishment has always recommended 235 00:13:31,440 --> 00:13:35,040 Speaker 1: something like I think, um, thirty minutes of exercise a day. 236 00:13:35,240 --> 00:13:39,160 Speaker 1: It's all about cardio usually cardio like walking, running, wommen, 237 00:13:39,240 --> 00:13:41,400 Speaker 1: getting the heart going, and yeah you need to do that. 238 00:13:41,440 --> 00:13:45,719 Speaker 1: But that has little to no effect on sarcopenia. But 239 00:13:45,920 --> 00:13:49,520 Speaker 1: resistance training does. Um, And they've done a bunch of 240 00:13:49,559 --> 00:13:51,400 Speaker 1: studies on this. I found out this is one of 241 00:13:51,440 --> 00:13:53,160 Speaker 1: those articles, Chuck, where I wrote it and there was 242 00:13:53,200 --> 00:13:56,320 Speaker 1: just so much awesome information out there. There's just a 243 00:13:56,360 --> 00:13:59,360 Speaker 1: really interesting article to write despite when it was assigned 244 00:13:59,360 --> 00:14:01,160 Speaker 1: to me, and I found out with sarcopenia was I 245 00:14:01,240 --> 00:14:03,200 Speaker 1: was like, you gotta be kidding me, right, why would 246 00:14:03,240 --> 00:14:06,760 Speaker 1: I be writing this? Yeah, me of all people, Um, 247 00:14:06,800 --> 00:14:09,360 Speaker 1: I need to write about whiskey. But there there's been 248 00:14:09,400 --> 00:14:11,320 Speaker 1: a bunch of studies that have turned up some really 249 00:14:11,360 --> 00:14:15,120 Speaker 1: surprising results. Right. So um, there was one that I 250 00:14:15,200 --> 00:14:18,840 Speaker 1: came across that put a group of elderly people age 251 00:14:19,560 --> 00:14:22,480 Speaker 1: eighty four. Yeah, this is pretty impressive unresistance training. And 252 00:14:22,800 --> 00:14:26,200 Speaker 1: by resistance training, we're talking about um, oh, I don't know. 253 00:14:26,280 --> 00:14:29,120 Speaker 1: You know where you lift legs weights with your legs 254 00:14:29,120 --> 00:14:31,640 Speaker 1: by just like flexing them out where I can't remember. 255 00:14:31,640 --> 00:14:35,040 Speaker 1: I don't know what it's called like bringing your I've 256 00:14:35,080 --> 00:14:40,040 Speaker 1: done it before, probably a doubt. If they recommend that 257 00:14:40,080 --> 00:14:42,440 Speaker 1: the elderly go in there and start hitting the bench press. No, 258 00:14:42,600 --> 00:14:45,120 Speaker 1: as a matter of fact, they recommend that the elderly 259 00:14:45,200 --> 00:14:49,080 Speaker 1: not try this first by themselves. They need at the 260 00:14:49,160 --> 00:14:51,960 Speaker 1: very least the advice of somebody who knows what they're 261 00:14:51,960 --> 00:14:53,840 Speaker 1: talking about at the gym, who works at the gym, 262 00:14:53,920 --> 00:14:56,360 Speaker 1: and they're not a personal trainer. You want to talk 263 00:14:56,400 --> 00:14:58,920 Speaker 1: to your doctor first if you're if you're elderly, but 264 00:14:59,120 --> 00:15:02,360 Speaker 1: we're The point here is is that if you are 265 00:15:02,400 --> 00:15:06,400 Speaker 1: elderly and you are developing circopania, it can actually be 266 00:15:06,480 --> 00:15:09,400 Speaker 1: reversed by resistance training. It was like, these signs of 267 00:15:09,440 --> 00:15:13,320 Speaker 1: aging can be reversed. Um. These this this study that 268 00:15:13,400 --> 00:15:15,800 Speaker 1: had seventy eight to eighty four year olds. They put 269 00:15:15,840 --> 00:15:19,040 Speaker 1: them on a resistance training program um and they saw 270 00:15:19,080 --> 00:15:22,760 Speaker 1: an increase of protein synthesis. Remember that's the stuff that 271 00:15:22,800 --> 00:15:24,880 Speaker 1: we that's the ability with los as we get older. 272 00:15:25,200 --> 00:15:28,040 Speaker 1: The increase was a hundred and eighty two percent. That's unreal. 273 00:15:28,800 --> 00:15:33,240 Speaker 1: That's huge because normally there's like increases and whenever you 274 00:15:33,280 --> 00:15:34,880 Speaker 1: look at a study it's like, oh, there was a 275 00:15:34,920 --> 00:15:39,920 Speaker 1: two percent change. That's significant different, This is enormously significant. 276 00:15:41,080 --> 00:15:44,640 Speaker 1: Just by doing weights, we can synthesize protein, right, yeah, 277 00:15:44,640 --> 00:15:47,360 Speaker 1: I can I tell them about the other one. Please do? Uh. 278 00:15:47,480 --> 00:15:48,840 Speaker 1: The U s d A did this one and they 279 00:15:48,880 --> 00:15:52,360 Speaker 1: said that the elderly participants who did resistance training for 280 00:15:52,360 --> 00:15:55,920 Speaker 1: forty five minutes three times a week saw for twelve 281 00:15:55,920 --> 00:15:58,680 Speaker 1: week over three month spans, on average, increase of thirty 282 00:15:59,440 --> 00:16:04,040 Speaker 1: muscle five increase in strength. Yeah, and that's huge, man, 283 00:16:04,600 --> 00:16:07,720 Speaker 1: that's forty five minutes three times a week in twelve weeks. 284 00:16:07,760 --> 00:16:11,200 Speaker 1: It's nothing. No, not much. And if you're seventy or eighty, 285 00:16:11,240 --> 00:16:14,480 Speaker 1: what else do you're not working? Yeah? Get the gym? Yeah, 286 00:16:14,720 --> 00:16:18,440 Speaker 1: Wapner commands you should we talk about astronauts well this Yeah, 287 00:16:18,480 --> 00:16:20,120 Speaker 1: I was hoping we get to this. The whole the 288 00:16:20,160 --> 00:16:23,160 Speaker 1: whole reason that we know that resistance training works is 289 00:16:23,240 --> 00:16:25,880 Speaker 1: thanks to our friends at NASA. This is weird, man. 290 00:16:26,360 --> 00:16:32,080 Speaker 1: What happens is astronauts have a similar existence as elderly 291 00:16:32,120 --> 00:16:34,440 Speaker 1: because it's very sedentary. They're in a space shuttle and 292 00:16:34,480 --> 00:16:37,000 Speaker 1: there's not much room. They're waitless. They're just hanging around, 293 00:16:37,080 --> 00:16:40,200 Speaker 1: drinking tang doing nothing. They never did nothing. For nobody. 294 00:16:40,440 --> 00:16:43,360 Speaker 1: Here's the interesting thing, Josher's and I know you know this. 295 00:16:43,760 --> 00:16:48,880 Speaker 1: They have an opposite effect. They're slow twitch. Well weightlessness, 296 00:16:48,960 --> 00:16:52,000 Speaker 1: weightlessness does well yeah, not not just if you're an astronaut, 297 00:16:52,720 --> 00:16:57,880 Speaker 1: but yeah, being being waitless. Uh, the fast twitch ones actually, uh, 298 00:16:58,000 --> 00:17:00,440 Speaker 1: the slow twitch ones dial first and in the fast 299 00:17:00,480 --> 00:17:03,160 Speaker 1: which ones to pick up the slack right rather than 300 00:17:03,360 --> 00:17:05,880 Speaker 1: down here on Earth where the fast twitched size off 301 00:17:05,920 --> 00:17:08,360 Speaker 1: first and then slow twitch picks up. And I've heard 302 00:17:08,359 --> 00:17:09,879 Speaker 1: of this. I didn't know the science behind it, but 303 00:17:09,920 --> 00:17:12,639 Speaker 1: I had heard that if you're weightless in space, like 304 00:17:12,680 --> 00:17:14,280 Speaker 1: these people that are up there for like a year 305 00:17:14,280 --> 00:17:17,040 Speaker 1: at the space station are coming back and like tearing 306 00:17:17,040 --> 00:17:19,920 Speaker 1: calf muscles, Like, yeah, that's the result of it. It's 307 00:17:19,960 --> 00:17:23,399 Speaker 1: not a loss of coordination, but very easily torn muscles 308 00:17:23,400 --> 00:17:27,240 Speaker 1: because the little the little precise, uh, fast twitch neurons 309 00:17:27,240 --> 00:17:29,919 Speaker 1: are not used to controlling like these huge you know, 310 00:17:30,200 --> 00:17:32,879 Speaker 1: they don't do the heave hoe that well. Yeah, so 311 00:17:32,960 --> 00:17:35,399 Speaker 1: that's to work this all out, if you know, and 312 00:17:35,440 --> 00:17:37,760 Speaker 1: outer space one day. Yeah. And I think the last 313 00:17:37,800 --> 00:17:40,719 Speaker 1: point is is, yes, you're supposed to do cardio. You're 314 00:17:40,760 --> 00:17:42,920 Speaker 1: supposed to do the thirty minutes of walking every day 315 00:17:42,960 --> 00:17:45,400 Speaker 1: to stay alive and all that. But the point is 316 00:17:45,400 --> 00:17:49,120 Speaker 1: is you can't walk. If you can't stand up straight right, 317 00:17:49,359 --> 00:17:51,600 Speaker 1: you can't walk away your sarcopanian. So you want to 318 00:17:51,720 --> 00:17:54,160 Speaker 1: you want to do the resistance training first. You want 319 00:17:54,160 --> 00:17:56,360 Speaker 1: to start on that. You want to start that regimen 320 00:17:56,440 --> 00:18:00,600 Speaker 1: first and then move into walking. And again, if you're 321 00:18:00,800 --> 00:18:03,719 Speaker 1: twelve years old and you're listening to us, you have 322 00:18:03,800 --> 00:18:05,959 Speaker 1: no idea how this applies to you, But my friends, 323 00:18:06,240 --> 00:18:12,480 Speaker 1: it does. Sarah, Sarah are no, she's twelve.
