In today’s episode, I talk about a study looking at whether more or less (frequency) is better when it comes to high intensity interval training.

In episode 11 of Science and Chill, I interview Dr. Michelle Cardel. 

Dr. Cardel is a researcher and scientist in obesity and nutrition and also a registered dietitian working in the Department of Health Outcomes and Biomedical Informatics at the University of Florida; she’s a fellow gator. 

Dr. Cardel’s education background includes a Bachelor’s degree in biology from Florida State University, a Master’s degree in clinical nutrition from the University of Alabama at Birmingham, and a PhD from UAB as well. After earning her PhD, Dr. Cardel completed a dietetics internship at UAB and the Alaskan Native Medical Center located in Anchorage, Alaska, and she also completed postdoctoral work at the University of Colorado Medical Center. She’s a member of the Academy of Nutrition and Dietetics, the Obesity Society, and the American Society for Nutrition.

Her current focus includes nutrition, obesity, weight management, pediatric obesity, and the psychosocial factors that contribute to obesity and health disparities in underserved and minority populations. 

In addition to talking about some of the causes and treatments for obesity, we cover a paper that Dr. Cardel recently published on the reasons for gender inequity in the ranks of academia and higher level positions with the university system.

In this week's installment of Physiology Friday, I discuss a recent studying showing that an exogenous ketone ester has no effect on glycogen utilization or high-intensity cycling performance above consuming carbohydrates alone.  Link to study:Exogenous ketosis impacts neither performance nor muscle glycogen breakdown in prolonged endurance exercise

In this special, off-beat episode of Science & Chill, I sit down with my great friends Kyle and Corey to record a "hybrid" episode of our podcasts. 

 

The conversation is wide ranging, and we touch upon things like weight stigma, COVID-19, morning routines, sports, and much more.

In this week's episode of Physiology Friday, I discuss a recent study that investigated the effects of a high-salt diet on the blood pressure response to exercise and endothelial function. Enjoy!  Study: High Salt Intake Augments Blood Pressure Responses During Submaximal Aerobic Exercise

In this episode of the podcast, I interview my longtime friend Jack Butler. Jack and I met each other through the sport of running, and have continued our personal and athletic relationship to this day.

Jack was also interviewing me for HIS podcast, so this is a bit of a two-way interview. We talk about our history in running, why we still run, and our thoughts on some of the more "cultural" aspects of running.

In addition, we speak on some topics concerning human longevity and why we do or don't want to live forever.

I hope you enjoy this conversation...I had a blast!

In this week's installment of Physiology Friday, I review a recent study which looked at whether breaking up sitting time with short bouts of 4-second sprints could improve the metabolic response to a high-fat, high-carbohydrate meal the next day.

Jason Koop is the head coach for CTS-ultrarunning, where he has managed hundreds of coaches and athletes to ultra marathon running success. But he doesn’t just coach, Jason is a talented and experienced ultrarunner himself, having finished ultramarathon races including the Badwater 135, Leadville trail 100, and the Western States 100.

Jason is also the author of the book “Training Essentials for Ultra Running: How to Train Smarter, Race Faster, and Optimize Your Ultramarathon Performance." Jason is also a podcaster in his own right; he hosts a podcast called The Koop Cast, which can be found on all major podcast platforms. I definitely suggest you check that out after you’ve listened to our conversation if you want to learn even more about the science behind running and some of Jason’s coaching philosophy.

In this episode, we cover a variety of topics including the science of low-carb diets and fat adaptation for endurance performance, how to coach and train for an ultramarathon, and what types of variables you should monitor to guide training. We also dig into Jason's coaching philosophy, how he determines which research is valuable, and the benefits and risks of "junk miles."

In episode 7 of Science & Chill, I talk with Dr. Nicholas Saner, a clinical research administrator at the Baker Institute in Melbourne Australia.

Dr. Saner completed his PhD in physiology from Victoria University, where his final project focused on the effects of sleep restriction on muscle protein synthesis and metabolic function. This paper caught my eye, and I wanted to interview Nick about this study in particular, as well as some of his other research pursuits, which have including genetics and their influence on army recruit performance and injury risk, as well as his current work using exercise for cancer therapy.

I hope you enjoy this episode. You can find links to relevant papers, Dr. Saner's research, and other topics in the show notes below.

In episode 6 of Science and Chill, I interview Dr. Brianna Stubbs, a translational scientist at the Buck Institute.

Dr. Stubbs earned her PhD from Oxford University in metabolic biochemistry, where she began her work on studying the effects of exogenous ketones in health and performance. She continues this work at the Buck and has published many studies on how exogenous ketone supplements might be used for athletic performance, metabolic diseases, and neurological conditions.

We talk ketosis, nerd out on endurance performance, and talk about her rich history as a world-champion rower and her current interests as a triathlete.

I hope you enjoy this wide-ranging conversation with a fascinating researcher!
