    5 Hours a Week: Cardio Training Guidance for Recreational Athletes

    You’re a busy person. Career, family, social obligations and everything else. What SHOULD you be doing for your cardio if you have just five hours a week to devote to your training? What’s the proper mix of long, slow effort, interval sessions and tempo bouts? How many times a week should you be getting out? And what’s the ideal duration per workout? To work out the answer, Marty and Stu invite on to the show the science journalist Alex Hutchinson, who has a physics Ph.D. from Cambridge and was on the Canadian national running team. He writes the Sweat Science column, on the science of human performance, for Outside magazine. He’s also the author of the bestselling books Endure and The Explorer’s Gene.  Together, the guys discuss: the challenge of cardio training when you’re not a professional athlete.  the current vogue for Marius Bakken and Norwegian Threshold training Norwegian Threshold Training’s implications for Zone 2 and other training protocols The optimal cardio training regimen for those who have five hours a week for training The challenge of intensity guidance and training thresholds    Send us ideas for future episodes, comments and listener questions at realexercisescience@gmail.com Exercise Science is powered by EverMe, the longevity intelligence app. To get a free, no credit card two-month trial to EverMe exclusively for Exercise Science listeners, go to: everme.ai/exercisescience Thanks also to our sponsor BiaFit, your all-in-one fitness platform designed to help you become the best version of yourself.

    Carbs vs. Keto: Fueling Optimal Performance with Louise Burke, Ph.D.

    What’s the most efficient way to fuel human performance during endurance sports? Australian Louise Burke is one of the best-known sports nutritionists on the planet, known for her Supernova race-walking studies that showed that keto- and low carb, high fat diets don’t fuel endurance athletes as well as carbohydrate-burning approaches. She also practices what she researches, holding the women’s Australian marathon record in her age group—the age group, she jokes, of “never you mind.”  In this episode Dr. Burke walks Stu and Marty through her research that found carb-based approaches to fueling yield about 5% more of the muscle cell’s energy currency, ATP, compared to fat-burning approaches, with carb-burning also yielding 7-8% better performance. She also: —discusses her own approach to fuelling endurance events —provides tips on carbohydrate periodization —answers a listener question about carb-loading —shows that carbs during a race are good for the brain  GUEST BIO Professor Louise Burke OAM, PhD, APD is a sports dietitian with 45 years of experience in the education and counselling of elite athletes. She worked at the Australian Institute of Sport for thirty years, rising to Chief of Nutrition Strategy. She has attended 6 Summer Olympic Games with the Australian Olympic Team. She was awarded a Medal of the Order of Australia in 2009. Louise is the Chair in Sports Nutrition at Australian Catholic University .

    Strength Training for Older People with Ashley Gluchowski, Ph.D.

    You have an older person in your life, or perhaps you are an older person yourself and you need that push to start strength training. This is the episode for you—because today we’re talking with Ashley Gluchowski, Ph.D., one of the most enthusiastic evangelists on strength training around and the University of Salford exercise scientist who helps older adults get stronger, improve balance and reduce risk of falls.   In this episode we discuss: The surprising activities of daily living that require strength as we get olderWhy older adults should be doing strength trainingThe association between strength and decreased dementia risk How to get over being intimidated by strength training The long-term benefits of making exercise social  Tips on how older adults can stick with strength-building programs Ashley is a clinical exercise physiologist and former student of Stu Phillips’ who has gone on to found Stronger At Home, a program designed to get older adults to start and stick with strength training (link below). She has years of experience working with older adults on how to start and stick with strength training—and in this episode, Stu and Marty interview her about what works (exercise classes), and what doesn’t (patronizing trainers). According to Ashley, “the short-term benefits of becoming stronger and more active include better glucose regulation, improved mood, increased energy, and better sleep.” The stereotype is that strength training is just for young people. But older people fighting sarcopenia are the ones who will most benefit from strength training most of all!

    How Much Protein Do You Need? | Stuart Phillips, McMaster University

    It’s no longer just the longevity bros and fitness fiends obsessing over their protein intake. So what does the science actually say about protein consumption? How much do you need, and what’s the best way to get it?  In today’s episode, Marty takes our own in-house world-renowned protein expert Stuart Phillips through the math behind the macros. In this episode Stu and Marty discuss: Stu says why the old guideline of 0.8 g/kg body weight wasn’t enough Does the benefit of protein hit a hard plateau at 1.6 g per kg per day? How much protein do you need if you want to stay strong as you get older? How much protein do you need if you want to lose weight but hold on to muscle? What’s better, vegan or animal protein?

    Exercise Snacks & VILPA: The Ultimate Explainer

    A little morsel of an episode on exercise snacks and Vigorous Intermittent Lifestyle Physical Activity, known as VILPA. Along with a handful of scientists around the world, Marty is leading research into the health benefits of short, vigorous bouts of exercise that are scattered through the day.  One key finding is that just four minutes of vigorous physical activity can decrease risk of all-cause mortality by 25%.  So in our eighth episode, Stu leads Marty through a discussion of the research into the benefits of short, vigorous bouts of physical activity. The guys discuss: —What’s the difference between exercise snacks and VILPA? —What health benefits are provided by short, vigorous bursts of exercise scattered throughout the day? —What are some examples of great exercise snacks that anyone can do? —What’s the shortest amount of exercise that will make a difference to one’s health? Finally, we explore the idea that exercise snacks and VILPA may be able to liberate physical activity from the confines of planned gym visits that require special clothing and fancy equipment.  Send us ideas for future episodes, comments and listener questions at realexercisescience@gmail.com Exercise Science is powered by EverMe, the longevity intelligence app. To get a free two-month trial to EverMe exclusively for Exercise Science listeners, go to: everme.ai/exercisescience Thanks also to our sponsor BiaFit, your all-in-one fitness platform designed to help you become the best version of yourself.

    Mythbusting the Most-Hyped Peptides

    Peptides like BPC-157, TB-500, CJC-1295 and retatrutide are among the hottest trends for optimizers, gym bros, looksmaxxers and the longevity crowd. But is it wise to inject bioactive molecules into the bloodstream that haven’t passed the drug approval process?   In this episode, Marty and Stu welcome the Harvard- and Stanford-educated Leigh Baxt, who mythbusts about peptides and other panaceas on Instagram @sciencemomscicomm.  Baxt is a translational scientist who specializes in drug development. She points out the many problems with injecting peptides into the body, including the major one that many of these peptides are activating biological pathways that cancer cells love.  In this episode we discuss the following questions:  What are peptides? Are peptides safe?  Quick guide to peptides like BPC-157, TB-500, CJC-1295 and retatrutide What do peptides do? What is a wolverine stack? Finally, we also walk through the drug-approval process that protects human beings from predatory marketing, and say what Marty, Stu and Leigh think is so wrong about promoting peptides to young people.  What scientific evidence supports peptide use?

    What to Do Instead of Zone 2 | Mike Joyner, Mayo Clinic

    If you’re a serious recreational athlete but you have a job and a life, and only five hours a week to train — what should you be doing? This week, Stu and Marty provide the answer with the help of one of the world’s foremost experts on aerobic conditioning and the limits of human performance, Dr. Michael Joyner of the Mayo Clinic. Dr. Joyner is a legend of the exercise science field and an elite runner himself, who back in 1991 conducted the first analysis establishing the physiologic possibility of a sub-two-hour marathon. Since our conversation with Joyner happened to fall just days after Sabastian Sawe achieved the first official sub-2:00 marathon times earlier this spring, the conversation begins with a discussion of Joyner’s 1991 analysis. Then Marty and Stu challenge Joyner to get specific about what amateur athletes should be doing, if they want to achieve the best possible aerobic fitness for health. How much vigorous training should we all be doing, relative to moderate- and low-intensity training? Plus a listener question asking how to know when you’re training too much.

    Muscle Mass & Weight Loss Drugs: Overblown Fears or Justified Concerns?

    Semaglutide, sold as Ozempic and Wegovy, and tirzepatide, sold as Zepbound and Mounjaro, are new weight loss drugs that actually work, helping millions around the world to feel better and become healthier. But some people are fearful of side effects, such as loss of muscle mass. Are their fears warranted?  To find out, Marty and Stu talk to the two University of Kansas weight-loss scientists, Renee Rogers and ACSM president-elect John Jakicic, who are leading a clinical trial investigating the way aerobic and resistance training can affect the muscle mass of people who are on GLP-1s, or the other new weight loss drugs.  In this episode: —how GLP-1s affect muscle mass —the difference between lean and muscle mass —the research that Jakicic and Rogers are doing into GLP-1s —guidance on whether people should be concerned about GLP-1s and muscle mass —how to minimize muscle loss while on GLP-1s  Plus, whether the new weight loss drugs affect men and women differently.  Have a listener question?
