1 00:00:00,840 --> 00:00:05,920 Speaker 1: Welcome to Fitness Disrupted, a production of My Heart Radio. 2 00:00:11,880 --> 00:00:19,920 Speaker 1: I am Tom Holland and this is Fitness Disrupted. Went 3 00:00:19,960 --> 00:00:26,440 Speaker 1: out for a run the other day and I enjoyed 4 00:00:26,440 --> 00:00:32,159 Speaker 1: it for a reason that was kind of new for 5 00:00:32,280 --> 00:00:36,600 Speaker 1: even me. And it goes to the topic of today's show. Now, 6 00:00:37,320 --> 00:00:40,159 Speaker 1: the topic of today's show. I have studied and I've 7 00:00:40,240 --> 00:00:44,120 Speaker 1: talked about it here, but for some reason, it's coming 8 00:00:44,159 --> 00:00:46,839 Speaker 1: up more and more in my studies and my research 9 00:00:46,880 --> 00:00:53,360 Speaker 1: and my readings. And it was just a different reason why, 10 00:00:53,920 --> 00:00:56,800 Speaker 1: along with the other things that made that run, that 11 00:00:57,000 --> 00:01:01,880 Speaker 1: exercise so enjoyable, this was up there in a way 12 00:01:01,920 --> 00:01:05,319 Speaker 1: it hadn't been in the past. And you're going, what 13 00:01:05,360 --> 00:01:07,200 Speaker 1: the heck are you talking about? I'm going to get there, 14 00:01:08,319 --> 00:01:12,640 Speaker 1: And in preparing for today's show, these words kept coming 15 00:01:12,720 --> 00:01:16,880 Speaker 1: up over and over again. Control the body, the mind, 16 00:01:17,880 --> 00:01:26,160 Speaker 1: myriad benefits, not weight loss belief over and over and 17 00:01:27,120 --> 00:01:30,920 Speaker 1: the longer I am in this industry, the more that 18 00:01:32,280 --> 00:01:37,560 Speaker 1: not weight loss topic just keeps coming up. Why Because 19 00:01:37,640 --> 00:01:43,880 Speaker 1: that's what exercise and even nutrition has just focused on 20 00:01:45,640 --> 00:01:53,200 Speaker 1: to its detriment. Exercise and that scale so connected with 21 00:01:53,280 --> 00:01:56,000 Speaker 1: so many people. And the problem is is, yes, that 22 00:01:56,080 --> 00:01:58,760 Speaker 1: it matters. It matters. We need to be a healthy weight. 23 00:01:58,800 --> 00:02:02,440 Speaker 1: Carrying around excess weight is a problem, leads to so 24 00:02:02,560 --> 00:02:05,640 Speaker 1: many different problems. So we need to be a healthy way. 25 00:02:05,680 --> 00:02:12,840 Speaker 1: But exercises so much more than that, you know. And 26 00:02:12,840 --> 00:02:15,480 Speaker 1: out of the three some odd shows, I'm not even 27 00:02:15,480 --> 00:02:18,280 Speaker 1: sure have we broken that yet. I gotta look. I mean, 28 00:02:18,360 --> 00:02:20,560 Speaker 1: this topic just keeps coming up over and over and 29 00:02:20,560 --> 00:02:24,720 Speaker 1: over again, but for good reason, for great reason, and 30 00:02:24,840 --> 00:02:27,680 Speaker 1: especially for the topic of today's show. And I'm gonna 31 00:02:27,720 --> 00:02:32,519 Speaker 1: focus on one specific study. You know, the last show, 32 00:02:33,120 --> 00:02:35,239 Speaker 1: I gave you the title of the study right away. 33 00:02:35,240 --> 00:02:37,840 Speaker 1: I gotta do that again. Why not white matter plasticity 34 00:02:37,919 --> 00:02:42,359 Speaker 1: in healthy older adults the effects of aerobic exercise. White 35 00:02:42,400 --> 00:02:47,919 Speaker 1: matter plasticity. Awesome, three awesome words. So today we're talking 36 00:02:47,919 --> 00:02:53,720 Speaker 1: about the brain. And someone reached out social media, going 37 00:02:53,760 --> 00:02:58,360 Speaker 1: back and forth about this very topic, one of the listeners. 38 00:02:58,560 --> 00:03:00,880 Speaker 1: And I always want to thank you for connecting and 39 00:03:00,919 --> 00:03:04,920 Speaker 1: reaching out with comments and questions. Helps me bring you 40 00:03:04,960 --> 00:03:10,079 Speaker 1: the best possible product here that interaction. What are your questions, 41 00:03:10,800 --> 00:03:15,400 Speaker 1: what are your concerns, what what are your obstacles? So 42 00:03:15,600 --> 00:03:20,080 Speaker 1: many emails and direct messages about that, So thank you 43 00:03:20,160 --> 00:03:25,880 Speaker 1: for that, but yes, the mind, the mind, you can't 44 00:03:25,919 --> 00:03:28,880 Speaker 1: measure that on a scale. You can measure it, Mr Eyes, 45 00:03:28,960 --> 00:03:33,200 Speaker 1: And what I'm going to talk about today, and I've 46 00:03:33,240 --> 00:03:37,960 Speaker 1: done the shows on what just feeling good. That exercise 47 00:03:38,000 --> 00:03:39,680 Speaker 1: makes you feel good. So when I went out for 48 00:03:39,720 --> 00:03:46,120 Speaker 1: that run, I felt so good at the end, so 49 00:03:46,200 --> 00:03:48,720 Speaker 1: much better in the middle than I did at the start. 50 00:03:49,960 --> 00:03:52,520 Speaker 1: And we've all had that experience. And it does not 51 00:03:52,760 --> 00:03:54,760 Speaker 1: have to be running, and it isn't for many of you. 52 00:03:55,800 --> 00:04:01,040 Speaker 1: It's biking, it's swimming, it's tennis, it's walk ging the 53 00:04:01,120 --> 00:04:04,160 Speaker 1: number one form of exercise, and then walking is involved 54 00:04:04,160 --> 00:04:09,920 Speaker 1: in this study. But it's not about weight loss. But 55 00:04:10,040 --> 00:04:15,839 Speaker 1: it's that awesome takeaway that I love to give you 56 00:04:16,000 --> 00:04:24,960 Speaker 1: and give you every show, just about that you have control, control, control, control. 57 00:04:27,320 --> 00:04:29,000 Speaker 1: You know, I was thinking as I was walking the 58 00:04:29,040 --> 00:04:31,520 Speaker 1: dogs this morning and thinking about the show, and you know, 59 00:04:31,560 --> 00:04:33,160 Speaker 1: I take notes and then I go for a walk 60 00:04:33,160 --> 00:04:35,680 Speaker 1: and I go over you know the notes in my head. 61 00:04:38,080 --> 00:04:39,880 Speaker 1: What if I turned around, What if people just said 62 00:04:39,880 --> 00:04:44,839 Speaker 1: to you, you're right, all those horrible bogus You know, 63 00:04:44,920 --> 00:04:48,479 Speaker 1: I was gonna say studies, but people interpreting studies erroneously, 64 00:04:48,920 --> 00:04:52,080 Speaker 1: that you don't have control, that you're doomed by your genetics, 65 00:04:53,560 --> 00:04:58,960 Speaker 1: and all of those completely false narratives. But if I 66 00:04:59,000 --> 00:05:00,880 Speaker 1: just said to your shirt, you're you forget it, You're 67 00:05:00,880 --> 00:05:03,320 Speaker 1: gonna die young. You have no control, just give up. 68 00:05:04,880 --> 00:05:10,239 Speaker 1: That's what they're saying, and it's wrong. And this study 69 00:05:10,440 --> 00:05:18,039 Speaker 1: will add fuel to that fire of control. And I'm 70 00:05:18,080 --> 00:05:21,240 Speaker 1: going to bring you this stuff over and over and 71 00:05:21,400 --> 00:05:23,600 Speaker 1: over again, because that's what it takes. I gonna take 72 00:05:23,600 --> 00:05:27,080 Speaker 1: one study to convince you, and it shouldn't one study. 73 00:05:27,120 --> 00:05:29,600 Speaker 1: There's if we could do just one study and that 74 00:05:29,640 --> 00:05:34,279 Speaker 1: would prove something, that would be awesome, but that's not 75 00:05:34,320 --> 00:05:38,360 Speaker 1: how it works. But I'm gonna hammer home over and 76 00:05:38,440 --> 00:05:41,760 Speaker 1: over with all of these different studies and all the 77 00:05:41,800 --> 00:05:46,039 Speaker 1: different clients stories and experiences the control issue because it's 78 00:05:46,120 --> 00:05:49,360 Speaker 1: so darn important. All right, quick break, when we come 79 00:05:49,360 --> 00:05:53,919 Speaker 1: back and get right into it. Amazing study White Matter 80 00:05:53,960 --> 00:05:57,600 Speaker 1: Plasticity and healthy older adults the effects of aerobic exercise. Now, 81 00:05:57,800 --> 00:06:01,120 Speaker 1: don't let that title scare you away. It's a really 82 00:06:01,240 --> 00:06:14,880 Speaker 1: amazing takeaway. We'll be right back and we are back 83 00:06:14,880 --> 00:06:20,840 Speaker 1: talking about exercise, specifically aerobic exercise. But that's what this 84 00:06:20,880 --> 00:06:26,800 Speaker 1: study looked at but strength training as well preserves the 85 00:06:26,960 --> 00:06:33,320 Speaker 1: muscles and your mind both. Do you ever hear that 86 00:06:33,440 --> 00:06:35,080 Speaker 1: on TV? That's what I was thinking about this morning 87 00:06:35,120 --> 00:06:36,919 Speaker 1: again walking the dogs. Do you hear that? No? What 88 00:06:37,000 --> 00:06:40,040 Speaker 1: do you hear? The pills and the products, the drugs 89 00:06:40,839 --> 00:06:43,720 Speaker 1: to help improve your memory, to help improve your muscles, 90 00:06:43,720 --> 00:06:52,680 Speaker 1: the supplements, they are super expensive and they just don't work. 91 00:06:53,480 --> 00:06:56,240 Speaker 1: I'm trying to think of a nice way to say it. 92 00:06:56,400 --> 00:07:00,880 Speaker 1: You know, and you have the solution, that is, and 93 00:07:00,920 --> 00:07:06,719 Speaker 1: not only is it free, it's the myriad benefits. It's 94 00:07:06,760 --> 00:07:11,280 Speaker 1: not one or two or six or ten side effects, 95 00:07:11,280 --> 00:07:15,400 Speaker 1: healthy side effects that come from strength training and aerobic 96 00:07:15,480 --> 00:07:21,040 Speaker 1: exercise and finding your healthy diet. It's dozens and dozens 97 00:07:21,040 --> 00:07:24,560 Speaker 1: and dozens. And so when you think you're not getting one, 98 00:07:24,760 --> 00:07:28,760 Speaker 1: like the scale moving, don't worry. You're getting all of 99 00:07:28,800 --> 00:07:32,440 Speaker 1: the others that you cannot see. And if you go 100 00:07:32,560 --> 00:07:35,920 Speaker 1: for that walk and it's not you know, just something 101 00:07:36,000 --> 00:07:38,280 Speaker 1: feel the way it usually does. You don't get that 102 00:07:38,400 --> 00:07:40,800 Speaker 1: hit of feel good hormones that you always do, or 103 00:07:40,800 --> 00:07:42,720 Speaker 1: maybe you're going a little slower, it feels a little 104 00:07:42,720 --> 00:07:46,280 Speaker 1: harder and you don't know why. Don't worry. You're still 105 00:07:46,280 --> 00:07:51,520 Speaker 1: getting all the other benefits. Every workout matters, every minute counts. 106 00:07:52,600 --> 00:07:54,920 Speaker 1: And so in preparing for the show, I was thinking 107 00:07:54,960 --> 00:07:59,400 Speaker 1: about sarcopenia right, talked about that how strength training is 108 00:07:59,400 --> 00:08:01,960 Speaker 1: the fountain of it because it preserves muscle. Sarcopenia is 109 00:08:02,000 --> 00:08:04,520 Speaker 1: the loss of muscle mass as we age. It is 110 00:08:04,560 --> 00:08:09,000 Speaker 1: not inevitable. It is preventable, and that comes through strength 111 00:08:09,000 --> 00:08:13,320 Speaker 1: training and adequate and take a protein. And that's awesome. 112 00:08:14,400 --> 00:08:21,840 Speaker 1: And just like you can prevent, mitigate, combat sarcopenia, you 113 00:08:21,880 --> 00:08:29,200 Speaker 1: can also combat brain issues white matter disease specifically that 114 00:08:29,280 --> 00:08:31,960 Speaker 1: I'm going to talk about that this study focuses on. 115 00:08:33,400 --> 00:08:36,959 Speaker 1: You can preserve your body and you can preserve your brain. 116 00:08:37,360 --> 00:08:42,760 Speaker 1: You have control. Is it perfect? Of course not, And 117 00:08:42,880 --> 00:08:47,280 Speaker 1: that's the problem. That's human nature to say, see this 118 00:08:47,360 --> 00:08:51,679 Speaker 1: person ended up this way even though they did X healthy. 119 00:08:51,880 --> 00:08:55,079 Speaker 1: The show I did about Jim Fix the quick tip, 120 00:08:55,440 --> 00:09:02,720 Speaker 1: that's the problem. But you have control, and when you 121 00:09:02,800 --> 00:09:07,760 Speaker 1: do healthy things consistently, really good things happen. But that 122 00:09:07,920 --> 00:09:11,360 Speaker 1: is why, as I've said before, I had to start 123 00:09:11,440 --> 00:09:14,400 Speaker 1: my most recent book, The Micro Workout Plan, by in 124 00:09:14,520 --> 00:09:18,240 Speaker 1: the introduction saying, you have to believe you have control, 125 00:09:20,000 --> 00:09:26,000 Speaker 1: incredible control, will things happen, of course, but we never 126 00:09:26,080 --> 00:09:30,120 Speaker 1: know what would have happened had you not done those things. 127 00:09:31,080 --> 00:09:34,640 Speaker 1: You know, Jim Fix dying at fifty two while running 128 00:09:35,240 --> 00:09:38,200 Speaker 1: most likely would have died back when his father did 129 00:09:39,040 --> 00:09:43,840 Speaker 1: in his thirties from a heart attack. But I digress. 130 00:09:43,920 --> 00:09:48,520 Speaker 1: But it's about control, people, and that's why study after 131 00:09:48,559 --> 00:09:51,079 Speaker 1: study I will bring you to show you that I'm 132 00:09:51,120 --> 00:09:53,840 Speaker 1: not just pulling this out of the air. This is science. 133 00:09:54,280 --> 00:09:58,480 Speaker 1: And in a time when science is finally getting it's 134 00:09:58,960 --> 00:10:04,640 Speaker 1: you know do, why don't you start focusing on that 135 00:10:06,160 --> 00:10:08,720 Speaker 1: with your strength, with your cardio, with your nutrition, and 136 00:10:08,800 --> 00:10:11,439 Speaker 1: feeling good about it, feeling so good about it as 137 00:10:11,480 --> 00:10:13,360 Speaker 1: I did during that run that I will get to 138 00:10:14,000 --> 00:10:17,880 Speaker 1: in uh just a few But you gotta look at 139 00:10:17,880 --> 00:10:20,360 Speaker 1: it that way. The same way you can preserve in 140 00:10:20,400 --> 00:10:23,960 Speaker 1: a similar fashion, you can preserve your muscle as you age. 141 00:10:24,080 --> 00:10:27,360 Speaker 1: You can preserve your mind. And it's use it or 142 00:10:27,440 --> 00:10:31,880 Speaker 1: lose it. For your body and your mind. We were 143 00:10:31,920 --> 00:10:35,280 Speaker 1: meant to move, we were meant to move forward. We're 144 00:10:35,320 --> 00:10:38,959 Speaker 1: not meant to sit. We're not meant to eat what 145 00:10:39,040 --> 00:10:43,760 Speaker 1: we eat today. But when you make small changes in 146 00:10:43,840 --> 00:10:47,560 Speaker 1: both of those areas, you will live your best life 147 00:10:47,559 --> 00:10:49,880 Speaker 1: because it's about quality of life for your body and 148 00:10:49,880 --> 00:10:51,560 Speaker 1: your brain. You can live to be a hundred, you 149 00:10:51,559 --> 00:10:54,679 Speaker 1: can live to be ninety, You'll live to be a 150 00:10:54,800 --> 00:10:57,120 Speaker 1: hundred and ten. But what are those years going to 151 00:10:57,160 --> 00:11:00,840 Speaker 1: be like? Will you be mobile? Will you be cognizant? 152 00:11:01,440 --> 00:11:06,960 Speaker 1: Or really have issues? So why white matter matters is 153 00:11:06,960 --> 00:11:10,280 Speaker 1: what we're going to talk about here, White matter disease. 154 00:11:11,600 --> 00:11:14,760 Speaker 1: I'm going to read you the definition. Okay, white matter disease. 155 00:11:14,760 --> 00:11:17,040 Speaker 1: We're talking about the brain here, people, is the wearing 156 00:11:17,040 --> 00:11:19,760 Speaker 1: a way of tissue in the largest and deepest part 157 00:11:19,800 --> 00:11:23,360 Speaker 1: of your brain that has a number of causes, including aging. 158 00:11:23,760 --> 00:11:27,320 Speaker 1: But we can't control aging, can we. This tissue contains 159 00:11:27,440 --> 00:11:31,560 Speaker 1: millions of nerve fibers or axons that connect other parts 160 00:11:31,600 --> 00:11:35,040 Speaker 1: of the brain and spinal cord and signal your nerves 161 00:11:35,440 --> 00:11:39,600 Speaker 1: to talk to one another. A fatty material called myelin 162 00:11:40,040 --> 00:11:43,600 Speaker 1: protects the fibers and gives white matter its color. I 163 00:11:43,600 --> 00:11:46,840 Speaker 1: feel like I'm back in my master's program studying myelin 164 00:11:47,080 --> 00:11:51,439 Speaker 1: and dendrites, all those kind of things. All right, This 165 00:11:51,520 --> 00:11:55,600 Speaker 1: type of brain tissue helps you think fast, walks straight, 166 00:11:56,360 --> 00:12:00,840 Speaker 1: and keeps you from falling. Mm hmm. These are important things. 167 00:12:00,840 --> 00:12:04,200 Speaker 1: As we age. Yes, when it becomes diseased, the mile 168 00:12:04,280 --> 00:12:07,480 Speaker 1: in breaks down. The signals that help you do these 169 00:12:07,520 --> 00:12:11,600 Speaker 1: things can't get through. Your body stops working like it should, 170 00:12:11,960 --> 00:12:14,240 Speaker 1: much like a kink in a garden hose makes the 171 00:12:14,280 --> 00:12:18,880 Speaker 1: water that comes out go awry. White matter disease happens 172 00:12:18,920 --> 00:12:22,840 Speaker 1: in older or elderly people. There are ways to prevent 173 00:12:22,960 --> 00:12:26,559 Speaker 1: or even reverse this condition, but you need to start now. 174 00:12:28,160 --> 00:12:30,440 Speaker 1: Let me go back. This type of brain tissue helps 175 00:12:30,480 --> 00:12:34,240 Speaker 1: you to think fast, important, walk straight, and keeps you 176 00:12:34,280 --> 00:12:38,640 Speaker 1: from falling. And as I read that preparing for the show, 177 00:12:38,679 --> 00:12:42,679 Speaker 1: I thought, well, strength training does that too, right, walk straight, 178 00:12:42,800 --> 00:12:45,840 Speaker 1: keep you from falling? You can control that as you age. 179 00:12:46,240 --> 00:12:48,480 Speaker 1: When you age and you fall and you break a hip, 180 00:12:50,160 --> 00:12:57,800 Speaker 1: not good, not good, And so control through strength training 181 00:12:58,240 --> 00:13:03,360 Speaker 1: and through exercise for the brain. All right, And what 182 00:13:03,400 --> 00:13:06,439 Speaker 1: we are talking about here I have talked about a 183 00:13:06,480 --> 00:13:09,320 Speaker 1: little bit prior episodes, and we will continue too because 184 00:13:09,320 --> 00:13:13,640 Speaker 1: it is so exciting. Is that enormous benefit of exercise 185 00:13:13,640 --> 00:13:19,080 Speaker 1: that has not talked about enough. Neuroplasticity or brain plasticity. 186 00:13:19,120 --> 00:13:22,400 Speaker 1: What is that? The ability of the brain to modify 187 00:13:22,640 --> 00:13:26,520 Speaker 1: its connections or rewire itself. You can make changes in 188 00:13:26,559 --> 00:13:29,439 Speaker 1: your body, and you can make changes in your brain. 189 00:13:31,120 --> 00:13:35,120 Speaker 1: And so here's the study, White matter plasticity and healthy 190 00:13:35,120 --> 00:13:42,600 Speaker 1: older adults the effects of aerobic exercise. This was October NeuroImage. 191 00:13:43,000 --> 00:13:46,199 Speaker 1: All right, First, I have to I have to say 192 00:13:46,240 --> 00:13:50,520 Speaker 1: that in researching this episode and this study in particular, 193 00:13:51,520 --> 00:13:54,440 Speaker 1: an article came up and it was all about the 194 00:13:54,480 --> 00:13:58,480 Speaker 1: best and how this study shows that aerobic exercise is 195 00:13:58,520 --> 00:14:05,400 Speaker 1: the best for the brain. Okay, we don't have to 196 00:14:05,440 --> 00:14:08,120 Speaker 1: focus on the best. Obviously there's value to knowing what 197 00:14:08,360 --> 00:14:12,000 Speaker 1: is effective and more effective, but it all matters. So 198 00:14:12,040 --> 00:14:14,920 Speaker 1: it's not that you're going to do just aerobic exercise 199 00:14:14,920 --> 00:14:20,160 Speaker 1: for your brain, because there are cognitive benefits of strength 200 00:14:20,160 --> 00:14:23,640 Speaker 1: training as well. So I understand why that article was 201 00:14:23,680 --> 00:14:25,520 Speaker 1: written the way it was, but I don't like it. 202 00:14:26,160 --> 00:14:28,440 Speaker 1: I don't need to know the best necessarily. You don't 203 00:14:28,440 --> 00:14:30,320 Speaker 1: need to know the best type of protein. You need 204 00:14:30,360 --> 00:14:32,320 Speaker 1: to eat your protein. You don't need to know the 205 00:14:32,360 --> 00:14:34,840 Speaker 1: best type of exercise for your brain. You need to 206 00:14:34,880 --> 00:14:39,240 Speaker 1: do cardio and strength. End of story. Two buckets. Now, yes, 207 00:14:39,320 --> 00:14:41,560 Speaker 1: the study will look at the better types and and 208 00:14:41,640 --> 00:14:46,160 Speaker 1: that bears discussion, and it will make sense for the brain, 209 00:14:46,640 --> 00:14:50,280 Speaker 1: not best, but effective in a certain way. And so 210 00:14:50,360 --> 00:14:53,200 Speaker 1: that word best needs to be parsed out, and it 211 00:14:53,400 --> 00:14:57,760 Speaker 1: never is except on this show, all right, So how 212 00:14:57,840 --> 00:14:59,880 Speaker 1: to how to get that off my chest? So let 213 00:14:59,880 --> 00:15:03,520 Speaker 1: me just read you the introduction to this study. Global 214 00:15:03,600 --> 00:15:07,680 Speaker 1: incidence of dementia is projected to double every twenty years, 215 00:15:08,120 --> 00:15:12,080 Speaker 1: Thus developing effective strategies to reduce the risk of cognitive 216 00:15:12,120 --> 00:15:18,520 Speaker 1: decline is critical. Cortical disconnection due to white matter degeneration 217 00:15:19,040 --> 00:15:23,080 Speaker 1: is considered one of the primary mechanisms of cognitive decline 218 00:15:23,120 --> 00:15:26,400 Speaker 1: in healthy aging. So think of white matter degeneration again 219 00:15:26,400 --> 00:15:30,880 Speaker 1: a sarcopenia of the brain. Okay, and maybe not not 220 00:15:30,960 --> 00:15:34,240 Speaker 1: the perfect analogy, but for our purposes it will help 221 00:15:34,760 --> 00:15:39,960 Speaker 1: and may proceed gray matter pathology in Alzheimer's disease. White 222 00:15:39,960 --> 00:15:43,800 Speaker 1: matter integrity decreases in healthy aging and dementia, as demonstrated 223 00:15:43,800 --> 00:15:48,520 Speaker 1: by studies using diffusion tensor imaging. As within person. Declines 224 00:15:48,600 --> 00:15:52,120 Speaker 1: in white matter integrity can occur over a period as 225 00:15:52,160 --> 00:15:57,600 Speaker 1: brief as six months, quickly people in cognitively healthy older adults. 226 00:15:58,000 --> 00:16:00,760 Speaker 1: And here's what I underlined. Here's the final sentence, here's 227 00:16:00,760 --> 00:16:05,760 Speaker 1: the takeaway, Here's the really important line. It is critical 228 00:16:06,160 --> 00:16:11,880 Speaker 1: to determine whether white matter deterioration is reversible or malleable, 229 00:16:12,400 --> 00:16:18,040 Speaker 1: can it be changed? And if so how? All right, 230 00:16:19,040 --> 00:16:22,160 Speaker 1: here's part of the abstract for you. White matter deterioration 231 00:16:22,320 --> 00:16:25,320 Speaker 1: is associated with cognitive impairment. We just read that. Learned 232 00:16:25,360 --> 00:16:29,040 Speaker 1: that in healthy aging in Alzheimer's disease, it is critical 233 00:16:29,040 --> 00:16:33,440 Speaker 1: to identify interventions that can slow down white matter deterioration. Yes, 234 00:16:33,480 --> 00:16:37,320 Speaker 1: repeating ourselves. So far clinical trials have failed to demonstrate 235 00:16:37,320 --> 00:16:40,320 Speaker 1: the benefits of aerobic exercise on the adult white matter 236 00:16:40,480 --> 00:16:45,400 Speaker 1: using diffusion magnetic resonance imaging m r S people. Here 237 00:16:45,440 --> 00:16:49,040 Speaker 1: we report the effects of a six month aerobic walking 238 00:16:49,160 --> 00:16:52,240 Speaker 1: and dance interventions. So now you're learning about this study 239 00:16:52,400 --> 00:16:56,880 Speaker 1: on white matter integrity and healthy older adults. Okay, six 240 00:16:56,960 --> 00:17:01,040 Speaker 1: month aerobic walking and dance interventions on the white matter 241 00:17:01,120 --> 00:17:05,320 Speaker 1: in healthy older adults hundred and eighty aged sixty to 242 00:17:05,560 --> 00:17:09,040 Speaker 1: seventy nine years. And they did this by measuring changes 243 00:17:09,119 --> 00:17:12,480 Speaker 1: in the ratio of calibrated T one to T two 244 00:17:12,480 --> 00:17:16,320 Speaker 1: weighted images. We don't need to understand that, and we continue. 245 00:17:16,800 --> 00:17:21,240 Speaker 1: Participants were community dwelling older adults again, average age about 246 00:17:21,280 --> 00:17:25,119 Speaker 1: sixty five years sixty were women enrolled in a twenty 247 00:17:25,119 --> 00:17:29,000 Speaker 1: four week randomized controlled exercise trial that examined the effects 248 00:17:29,040 --> 00:17:36,480 Speaker 1: of aerobic exercise on cognitive performance and brain health. All Right, 249 00:17:37,680 --> 00:17:40,399 Speaker 1: so they collected baseline data, don't need to give you 250 00:17:40,440 --> 00:17:43,080 Speaker 1: all that, and then they were assigned to one of 251 00:17:43,280 --> 00:17:48,240 Speaker 1: four interventions implemented over four waves from October two eleven 252 00:17:48,560 --> 00:17:52,159 Speaker 1: to November two fourteen. When we come back from the 253 00:17:52,280 --> 00:17:56,160 Speaker 1: final break, I'm going to give you those four interventions 254 00:17:56,560 --> 00:17:58,359 Speaker 1: and what they found. All right, final break, we'll be 255 00:17:58,440 --> 00:18:16,760 Speaker 1: right back talking about exercise preserving your mind, helping to 256 00:18:16,880 --> 00:18:21,879 Speaker 1: improve your cognitive health. Benefit of exercise that is not 257 00:18:22,000 --> 00:18:26,640 Speaker 1: found on your scale, people, or in the mirror. Let's 258 00:18:26,640 --> 00:18:30,280 Speaker 1: stop looking at the scale and the mirror, or stop 259 00:18:30,320 --> 00:18:34,360 Speaker 1: looking at it as much. Both of those things will 260 00:18:34,480 --> 00:18:36,880 Speaker 1: change when you take the focus off. As I've said 261 00:18:36,880 --> 00:18:40,040 Speaker 1: in the past. All Right, For intervention groups for this study, 262 00:18:40,040 --> 00:18:47,000 Speaker 1: whereas follows, The active control involved exercises designed to improve flexibility, strength, 263 00:18:47,040 --> 00:18:50,320 Speaker 1: and balance with the aid of yoga mats and blocks, chairs, 264 00:18:50,320 --> 00:18:54,240 Speaker 1: and resistance bands specifically designed for individuals sixty years of 265 00:18:54,280 --> 00:18:58,040 Speaker 1: age and older. This intervention served as the active control 266 00:18:58,080 --> 00:19:00,800 Speaker 1: group to account for the social engage each mint and 267 00:19:00,960 --> 00:19:04,119 Speaker 1: novelty in the other interventions. With the difference than the 268 00:19:04,359 --> 00:19:07,879 Speaker 1: that the active control was not aimed to increase cardio 269 00:19:07,920 --> 00:19:12,240 Speaker 1: respiratory fitness. Okay, interesting. The walking intervention was designed to 270 00:19:12,320 --> 00:19:16,520 Speaker 1: increase cardio respiratory fitness. Thus it involved walking sessions at 271 00:19:16,600 --> 00:19:21,439 Speaker 1: fifty to six maximum heart rate, so not easy but 272 00:19:21,480 --> 00:19:25,840 Speaker 1: not super hard. As ascertained from a maximum graded exercise test, 273 00:19:26,200 --> 00:19:29,439 Speaker 1: walking duration increased from twenty to forty minutes during the 274 00:19:29,440 --> 00:19:33,040 Speaker 1: first six weeks of the program. During the remaining eighteen weeks, 275 00:19:33,040 --> 00:19:37,080 Speaker 1: participants walked for forty minutes at six their maximum heartrate 276 00:19:37,119 --> 00:19:39,400 Speaker 1: each session. So now that's pushing it. That's a that's 277 00:19:39,400 --> 00:19:42,600 Speaker 1: a good walk, a good intensity. Frequent assessment of heart 278 00:19:42,720 --> 00:19:47,879 Speaker 1: rate using either palpatient or polar heart rate monitors, and 279 00:19:48,040 --> 00:19:52,439 Speaker 1: rating of perceived exertion ensured that participants exercise was performed 280 00:19:52,520 --> 00:19:54,960 Speaker 1: at the prescribed intensity. So that's good. They're they're monitory. 281 00:19:55,000 --> 00:19:57,560 Speaker 1: They this is not not just uh, you know, hey, 282 00:19:57,600 --> 00:19:59,240 Speaker 1: on a scale of one to ten, how do you feel? 283 00:19:59,840 --> 00:20:03,240 Speaker 1: H um. They're using that, but they're also using heart rate. 284 00:20:03,400 --> 00:20:08,200 Speaker 1: Exercise logs were completed after each exercise session. The walking 285 00:20:08,240 --> 00:20:10,800 Speaker 1: plus nutrition group, so this is the third one. In 286 00:20:10,840 --> 00:20:14,200 Speaker 1: addition to the above, walking intervention received a nutritional supplement 287 00:20:14,200 --> 00:20:19,920 Speaker 1: containing antioxidants, anti inflammatories, vitamins, minerals, and beta alanine. Beta 288 00:20:19,960 --> 00:20:22,639 Speaker 1: alanine is thought to promote the effect of increased cardio 289 00:20:22,640 --> 00:20:28,080 Speaker 1: respiratory fitness by increasing lean muscle mass. However, the analyses 290 00:20:28,119 --> 00:20:30,960 Speaker 1: of the primary outcomes indicated no difference in gain in 291 00:20:31,000 --> 00:20:35,280 Speaker 1: cardio respiratory fitness between the walking interventions. Therefore, walking and 292 00:20:35,400 --> 00:20:39,520 Speaker 1: nutrition were combined. That's interesting. And finally, the dance intervention 293 00:20:39,640 --> 00:20:44,480 Speaker 1: was designed to provide simultaneous cognitive and social enrichment combined 294 00:20:44,520 --> 00:20:49,480 Speaker 1: with aerobic physical activity. The choreographed dance combinations became progressively 295 00:20:49,560 --> 00:20:53,600 Speaker 1: more challenging over the course of the six months program groups. 296 00:20:53,640 --> 00:20:57,280 Speaker 1: Social dance styles were selected to minimize lead follow rules. 297 00:20:57,600 --> 00:21:01,200 Speaker 1: In each session, participants learned for dance and recorded their 298 00:21:01,240 --> 00:21:05,520 Speaker 1: heart rate and perceived exertion after each dance. Each participant 299 00:21:05,640 --> 00:21:08,720 Speaker 1: learned and alternated between the two roles for each dance. 300 00:21:08,800 --> 00:21:11,879 Speaker 1: Increasing the cognitive challenge is a really interesting study. So 301 00:21:11,920 --> 00:21:16,480 Speaker 1: they're challenging them mentally, They're doing different types of exercise 302 00:21:16,600 --> 00:21:19,679 Speaker 1: to get the heart rate up. There's the social component 303 00:21:20,040 --> 00:21:23,000 Speaker 1: they tried to add that nutrition in, decided hey, that's 304 00:21:23,040 --> 00:21:26,000 Speaker 1: not really making a difference, and combined them and let's 305 00:21:26,000 --> 00:21:30,560 Speaker 1: see what they found. Specifically, the aerobic walking and social 306 00:21:30,640 --> 00:21:35,359 Speaker 1: dance interventions resulted in positive changes in the T one 307 00:21:35,600 --> 00:21:39,600 Speaker 1: W T two W signal in late milinating regions. It's 308 00:21:39,600 --> 00:21:41,919 Speaker 1: gonna make sense in the second people, as compared to 309 00:21:41,960 --> 00:21:45,119 Speaker 1: widespread decreases in the T one W T two W 310 00:21:45,359 --> 00:21:49,680 Speaker 1: signal in the active control. Notably, in the aerobic walking group, 311 00:21:49,720 --> 00:21:52,560 Speaker 1: positive change in the T one W T TWOW signal 312 00:21:52,880 --> 00:21:58,320 Speaker 1: correlated with improved episodic memory performance. Okay, pulling this stuff out, 313 00:21:58,400 --> 00:22:01,919 Speaker 1: that's what That's what's important, right are So in the 314 00:22:01,960 --> 00:22:08,760 Speaker 1: walking group it correlated with positive improved memory performance. Episodic 315 00:22:08,800 --> 00:22:16,080 Speaker 1: memory performance. Walking is helping your memory. Lastly, intervention induced 316 00:22:16,119 --> 00:22:20,080 Speaker 1: increases in cardio respiratory fitness did not correlate with changes 317 00:22:20,119 --> 00:22:22,720 Speaker 1: in the T one W T two signal T two 318 00:22:22,800 --> 00:22:28,120 Speaker 1: W signal. So don't worry about your fitness level, don't 319 00:22:28,119 --> 00:22:31,760 Speaker 1: worry about how fast you're going. At least at the start. 320 00:22:31,920 --> 00:22:37,040 Speaker 1: You're getting the benefit potentially of this memory, of this 321 00:22:37,240 --> 00:22:43,119 Speaker 1: white matter, of the connections of the neural performance from walking. So, 322 00:22:43,160 --> 00:22:45,120 Speaker 1: in other words, those metrics that we get so hung 323 00:22:45,160 --> 00:22:49,520 Speaker 1: up on cardio respiratory fitness, You're going to improve that 324 00:22:49,560 --> 00:22:51,760 Speaker 1: over time, but don't worry about it. Don't get stuck 325 00:22:51,760 --> 00:22:54,200 Speaker 1: in the numbers, is my point. People. So I'm trying 326 00:22:54,240 --> 00:22:57,160 Speaker 1: to go you're getting benefits. You know when people say 327 00:22:57,200 --> 00:22:59,560 Speaker 1: to me, uh, you know, I only walk at this 328 00:22:59,640 --> 00:23:04,520 Speaker 1: pace or I only walk this stop stop. All right, 329 00:23:05,200 --> 00:23:10,200 Speaker 1: So what's the takeaway? You know, talking about milinating regions 330 00:23:10,200 --> 00:23:13,520 Speaker 1: and things like that, you have no idea what that means. Okay, 331 00:23:13,960 --> 00:23:18,960 Speaker 1: two paragraphs for conclusions. Here Together, our findings suggest that 332 00:23:19,040 --> 00:23:23,680 Speaker 1: white matter regions that are vulnerable to aging retain some 333 00:23:23,800 --> 00:23:31,160 Speaker 1: degree of plasticity that can be induced by aerobic exercise training. 334 00:23:31,840 --> 00:23:35,240 Speaker 1: I have that in bold. I have that underlined, and 335 00:23:35,280 --> 00:23:39,240 Speaker 1: I'm going to read it again. Our findings suggest suggest 336 00:23:40,040 --> 00:23:43,280 Speaker 1: does it proof positive? Of course, not suggest that white 337 00:23:43,280 --> 00:23:48,040 Speaker 1: matter regions we just learned it's important that are vulnerable 338 00:23:48,080 --> 00:23:53,240 Speaker 1: to aging retains some degree. Some degree. I'll take some degree, people, 339 00:23:54,359 --> 00:23:56,160 Speaker 1: and then if I'm eating healthy and doing other things, 340 00:23:56,200 --> 00:23:59,120 Speaker 1: maybe that's some degree turns into a large degree. There's 341 00:23:59,160 --> 00:24:02,960 Speaker 1: no one thing, some degree of plasticity that can be 342 00:24:03,040 --> 00:24:11,200 Speaker 1: induced by aerobic exercise training. That's great news. That's amazing news. 343 00:24:11,920 --> 00:24:16,639 Speaker 1: That's news that we don't hear enough. Where Where are 344 00:24:16,680 --> 00:24:21,720 Speaker 1: the Instagram posts about exercise and your brain? No, you 345 00:24:21,760 --> 00:24:25,240 Speaker 1: see the body, you see the butts there? I said it, 346 00:24:25,320 --> 00:24:27,480 Speaker 1: had to say it. Oh my god, I'm so tired 347 00:24:27,480 --> 00:24:32,040 Speaker 1: of those pictures. I digress. I didn't think I'd go 348 00:24:32,119 --> 00:24:36,440 Speaker 1: there anyway. In addition, we provided evidence that the T 349 00:24:36,600 --> 00:24:39,760 Speaker 1: one W T two W signal may be a useful 350 00:24:39,840 --> 00:24:43,800 Speaker 1: and broadly accessible measure for studying short term within person 351 00:24:43,840 --> 00:24:47,480 Speaker 1: plasticity and deterioration in the adult human white matter. Okay, 352 00:24:47,520 --> 00:24:53,040 Speaker 1: great news for future study. And one more concluding paragraph 353 00:24:53,119 --> 00:24:57,280 Speaker 1: reiterates what we just read. Our study provides evidence for 354 00:24:57,320 --> 00:25:00,240 Speaker 1: white matter plasticity and older adults induced by a bick 355 00:25:00,320 --> 00:25:05,359 Speaker 1: walking and dance and dance. So aerobic walking worked, and dance. 356 00:25:06,400 --> 00:25:09,120 Speaker 1: Move your body, get your heart rate up. I don't 357 00:25:09,160 --> 00:25:13,720 Speaker 1: care how you do it. There is no one best way. 358 00:25:13,840 --> 00:25:15,840 Speaker 1: The best way is the one you enjoy, do frequently, 359 00:25:16,000 --> 00:25:19,680 Speaker 1: and ideally mix it up as well. Measured by an 360 00:25:19,680 --> 00:25:23,080 Speaker 1: increase in T one W T two W signal, the 361 00:25:23,119 --> 00:25:25,520 Speaker 1: findings suggests that the white matter in the adult brain 362 00:25:25,680 --> 00:25:29,080 Speaker 1: retains plasticity in voldnemble regions and reading it again, just 363 00:25:29,160 --> 00:25:33,119 Speaker 1: written slightly differently, and that these changes can be observed 364 00:25:33,160 --> 00:25:37,959 Speaker 1: on a short term scale. So it's a short study 365 00:25:38,000 --> 00:25:44,000 Speaker 1: relatively speaking, and they saw positive changes. Further studies are 366 00:25:44,000 --> 00:25:46,879 Speaker 1: needed to understand that exercise induced adaptations that lead to 367 00:25:47,000 --> 00:25:50,439 Speaker 1: increased T one W T two W and that mediate 368 00:25:50,480 --> 00:25:59,280 Speaker 1: effects on episodic memory function. All workouts matter, and when 369 00:25:59,320 --> 00:26:02,639 Speaker 1: people ask and I understand it, I get it. You 370 00:26:02,640 --> 00:26:06,840 Speaker 1: know if I stop exercising, you know how soon will 371 00:26:06,920 --> 00:26:11,399 Speaker 1: I lose muscle? How soon? Don't worry about those things 372 00:26:12,400 --> 00:26:16,160 Speaker 1: worry about focus on the benefits of every single one 373 00:26:17,240 --> 00:26:23,200 Speaker 1: of preserving now that you know white matter your brain. 374 00:26:26,960 --> 00:26:29,159 Speaker 1: It's not how much time you take off. It's not 375 00:26:29,359 --> 00:26:34,760 Speaker 1: how you try to do the best work out possible, 376 00:26:34,800 --> 00:26:43,879 Speaker 1: the hardest. No, it's the consistency and it's the focusing 377 00:26:44,080 --> 00:26:53,719 Speaker 1: on the healthy habits for the multitude of positive health outcomes. 378 00:26:55,840 --> 00:26:57,159 Speaker 1: We all want to look good in the mirror. I 379 00:26:57,200 --> 00:26:59,679 Speaker 1: get it. We all want to fit into our clothes 380 00:26:59,680 --> 00:27:02,199 Speaker 1: as ust as we can, or many people do, and 381 00:27:02,240 --> 00:27:05,520 Speaker 1: we should be that the healthiest weight we can be 382 00:27:06,480 --> 00:27:11,120 Speaker 1: so that we don't have arthritic issues, have increased risk 383 00:27:11,160 --> 00:27:17,600 Speaker 1: of so many things, heart disease, diabetes, multiple cancers. Leave 384 00:27:17,640 --> 00:27:21,359 Speaker 1: you with this same way I started. You have to 385 00:27:21,400 --> 00:27:26,080 Speaker 1: believe you have control, and I'm giving you study after study, 386 00:27:26,680 --> 00:27:32,920 Speaker 1: show after show to reiterate that we do. I will 387 00:27:32,920 --> 00:27:36,879 Speaker 1: give you the science to help strengthen your resolve, to 388 00:27:37,000 --> 00:27:41,880 Speaker 1: help strengthen the habits that you are trying to implement. 389 00:27:43,119 --> 00:27:45,879 Speaker 1: That's the hardest part. I understand. I spent half my 390 00:27:45,960 --> 00:27:49,000 Speaker 1: life training clients, trying to get them to make you 391 00:27:49,119 --> 00:27:52,920 Speaker 1: healthy habits outside of the session. Session in and of itself, 392 00:27:55,119 --> 00:27:57,040 Speaker 1: you know, come to me one to three times a week, 393 00:27:57,080 --> 00:28:01,000 Speaker 1: back and then awesome. But my ultimate was to change 394 00:28:01,000 --> 00:28:06,479 Speaker 1: her habits outside the session and to give you the 395 00:28:06,520 --> 00:28:13,600 Speaker 1: belief that it mattered. So back to my run. This 396 00:28:13,720 --> 00:28:16,639 Speaker 1: was a later in the day run. I'm finding harder 397 00:28:16,680 --> 00:28:19,239 Speaker 1: and harder to do those runs later in the day 398 00:28:19,320 --> 00:28:22,320 Speaker 1: some days that I'm up for it more often than not. 399 00:28:23,200 --> 00:28:25,080 Speaker 1: I wish I would have done it earlier in the day. 400 00:28:27,320 --> 00:28:31,720 Speaker 1: But I just started getting into this study and the 401 00:28:31,760 --> 00:28:35,240 Speaker 1: research for the show when I was getting ready for 402 00:28:35,240 --> 00:28:38,000 Speaker 1: this run, and I thought, you know what I'm gonna 403 00:28:38,480 --> 00:28:40,920 Speaker 1: I'm gonna run because it's it's really good for my head, 404 00:28:41,000 --> 00:28:44,320 Speaker 1: and I knew that my brain, and this research was 405 00:28:44,520 --> 00:28:48,760 Speaker 1: fresh in my mind, pun intended, and it was a 406 00:28:48,840 --> 00:29:00,160 Speaker 1: different enjoyment. It was another box just checked of benefits 407 00:29:00,160 --> 00:29:04,840 Speaker 1: that again I knew, but it was just stronger. I 408 00:29:04,880 --> 00:29:06,840 Speaker 1: felt better about the run in a different way, and 409 00:29:06,880 --> 00:29:08,840 Speaker 1: I felt good from the run. I felt, you know, 410 00:29:09,000 --> 00:29:12,600 Speaker 1: good from being outside. Went longer than I thought I would. 411 00:29:14,040 --> 00:29:17,320 Speaker 1: But as I get older, fifty two, I know that 412 00:29:17,760 --> 00:29:21,240 Speaker 1: I need to protect as much as I can of 413 00:29:21,320 --> 00:29:26,000 Speaker 1: my body and my brain, and I have control and 414 00:29:26,040 --> 00:29:29,240 Speaker 1: I don't have to do a lot, and it all matters, 415 00:29:29,280 --> 00:29:33,840 Speaker 1: and it all adds up and it feels good. But 416 00:29:33,880 --> 00:29:35,880 Speaker 1: when you take your focus off of the weight and 417 00:29:35,920 --> 00:29:41,440 Speaker 1: the scale and all of those other things, those will come. 418 00:29:42,960 --> 00:29:46,480 Speaker 1: They have to come if you are consistent. They have to. 419 00:29:47,360 --> 00:29:49,280 Speaker 1: If you better the way you eat, you're taking in 420 00:29:49,320 --> 00:29:52,840 Speaker 1: fewer calories, you're feeling better about yourself, you are exercising more, 421 00:29:52,880 --> 00:29:55,640 Speaker 1: you're burning more calories. The body will change for the 422 00:29:55,680 --> 00:30:01,360 Speaker 1: positive physically outwardly. But my whole point is that there's 423 00:30:01,560 --> 00:30:03,760 Speaker 1: so much more to it. And when you change from 424 00:30:03,800 --> 00:30:08,080 Speaker 1: the inside and focus on that first stuff, you can't see, 425 00:30:09,360 --> 00:30:12,280 Speaker 1: but you believe that you want to be the best 426 00:30:12,320 --> 00:30:19,520 Speaker 1: you can be at It changes your entire focus, outlook, 427 00:30:19,760 --> 00:30:26,320 Speaker 1: and enjoyment of everything you do. That is healthy. All right? 428 00:30:28,040 --> 00:30:34,520 Speaker 1: That was fun. Why white matter matters. Exercise is awesome 429 00:30:36,080 --> 00:30:40,520 Speaker 1: and we're still learning. We're still learning all the benefits. 430 00:30:41,160 --> 00:30:44,120 Speaker 1: All right.
