A collection of podcasts that I’ve found interesting over time on fitness, training or nutrition. Some are extremely technical, and some fairly straight forward. I’ve included some of my commentary that I’ve shared with other coaches and some of my athletes. They are in no particular order:
Anyone can qualify for Kona. Although geared toward triathlon, some good general concepts on limiters and VO2 max trainability. https://podcasts.apple.com/si/podcast/anybody-can-be-kona-qualifier-genetics-is-not-your/id1209821045?i=1000441749964
Here’s an article based on this as well.
Improve your running speed and performance. Not necessarily what I’d consider one of my favorites, but pretty practical overall. https://podcasts.apple.com/us/podcast/that-triathlon-show/id1209821045?i=1000453394957
Sports psychology https://podcasts.apple.com/us/podcast/faster-podcast-by-flo-episode-9-sports-psychology-master/id1368799871?i=1000417213893
These three go together… and somewhat mirror what Alan Couzens said. This is a sports scientist who really focuses on (or made popular) the idea of “polarized” training… keeping easy work easy and doing hard work hard… and the “ideal” ratio is 90% easy and only 10% hard. He feels that it’s not productive to spend time between LT1 (lactate threshold point 1… where lactate starts increasing more significantly above baseline) and LT2 (where lactate is no longer steady state… it builds fast meaning you can’t spend a lot of time there. FTP tests estimate this point). So, depending on where LT1 is, he advocates not doing tempo or sweet spot work. I don’t necessarily think this is optimum per se… but there are a lot of valid points here. The reason I say this is Seiler’s hedges at is that when he starts talking about transition points… sometimes it seems to work up to around 80% intensity (on the bike), which would be low tempo. Likewise, his threshold workout cutoffs seem to extend a little lower than threshold too, when limited by HR high limits (from a practical standpoint). Still… I think it’s good to understand, as well as understanding some of the limitations. From my experience, I think that tempo and sweet spot work can improve stamina (ability to hold intermediate power longer) as well as bumping FTP. They may not necessarily improve VO2 max, but they can help increase your FTP relative to VO2 max. And these are somewhat practical operating points for long-course triathletes and ultra-cyclists. A 70.3 bike is executed typically in a low tempo range, from 78-83% of FTP. Practicing this… getting your body and mind around holding this for several hours… provides race specific benefits. Again, I do think there is value in understanding this methodology as a whole, and the importance of not getting too overboard with too much high intensity training. Three podcasts, in order:
Polarized training: https://www.velonews.com/2018/07/podcast/fast-talk-podcast-ep-51-polarizing-your-training-with-dr-stephen-seiler_473325
Applying polarized training: https://www.velonews.com/2018/08/podcast/fast-talk-podcast-ep-54-applying-the-polarized-training-model-with-dr-seiler_477253
High intensity training: https://www.velonews.com/2019/05/training/fast-talk-podcast-ep-75-high-intensity-training-with-dr-stephen-seiler_494377
Now on the other end of the spectrum… these podcasts sort of go together. These tend to focus more training on that middle area, and some of the benefits… particularly around improving fat oxidation rates. Being a better fat burner significantly improves the margin for error on nutrition when doing long events. If you are a high carb burner, you need to take in a lot of carbs while you ride or run, increasing the risk of GI distress. These discussions lead me to adopting the INSCYD testing methodology for some athletes, with the goal of helping people becoming better fat burners.

FTP, VO2Max and VLaMax. This is the person who created INSCYD, and this helps providing some understanding the background. It’s a bit technical, but a good reference. There’s a really important point to grasp in this one on VLaMax (anaerobic capacity) and VO2Max (anaerobic capacity), and how building too much VLaMax can negatively impact your threshold power: https://scientifictriathlon.com/tts169/

GI Distress & Gut training… a lot of good nuggets here: https://www.trainingpeaks.com/blog/gut-training-for-endurance-athletes-with-patrick-wilson/
Keto diet. I include this as a reference. There’s a lot of anecdotal stories about the wonders of the keto diet. These RD’s discuss the research, then try it, and discuss the practical side. I don’t advocate one dietary preference or another. I do think it’s good to understand potential limitations associated with different choices by athletes. This is a two part podcast:
i) The science https://www.thenutritionwonk.com/single-post/2018/11/05/n-1-Episode-1-Science-of-Keto
ii) The experience https://www.thenutritionwonk.com/single-post/2018/12/02/n1-Episode-2-The-Keto-ExperienceMetabolism. This is a really interesting discussion on how we cannot increase/decrease metabolism actively… our bodies adjust metabolism to work within a general range to maintain energy balance. Shifted my thinking on the topic substantially: https://podcasts.apple.com/us/podcast/herman-pontzer-phd-burn/id1042673386?i=1000511482369
Male / Female differences in performance and nutrition:
Dr. Stacey Sims: She’s a well known scientist / researcher who has focused on the differences between men and women. She does a nice job of explaining how menstrual cycles impact training, as well as some strategies for mitigating some of the differences. High progesterone (closer to the end of the cycle before progesterone / estrogen drops) can impair intensity capacity, reducing power output, as well as impacting core temp and possibly heat tolerance. Understanding some of the potential impacts of normal hormone changes can better help you set expectations or make adjustments in training as necessary (e.g. if you are impacted and the schedule is for sweet spot work, dropping to tempo may make more sense). She also covers the potential impact from oral contraceptives… with the short version that they can negatively impact overall athletic performance (not making a recommendation with this, just summarizing her comments). Here are some of the podcasts I’ve listened to from Dr Sims that may be of interest.
This is a really great podcast from Dr. Sims… if you want to get one overview, this is it: https://podcasts.apple.com/us/podcast/fast-talk-ep-74-why-women-are-not-small-men-with-dr-stacy-sims/id1151541159?i=1000438699334
Another similar podcast, covering some additional information / nuances (more "how to" in this one, nutritional strategies)… Work with your body rather than against it: https://podcasts.apple.com/us/podcast/099-dr-stacy-sims-on-how-to-work-your-body-not-fight/id1204966485?i=1000433133236
This podcast is also from Dr Sims, on Menopause nutrition:https://podcasts.apple.com/us/podcast/episode-50-dr-stacy-sims-menopause-nutrition-female/id1294337640?i=1000436485087
Dr. Kirsty Elliote-Sale.
Energy availability, and menstrual disorders. I thought this was an extremely informative podcast… I’d put this up with the first Sim’s podcast above and highly recommend listening to it. Having menstrual cycles makes it easier to identify low energy availability (meaning you are consuming less energy than you are expending, at a point where it’s detrimental to performance and possibly health), through observation of variation in cycles: https://sigmanutrition.com/episode280/
She has recently done some great articles on the impact of menstrual cycles and oral contraceptives, that may be less extreme (e.g. the impacts are very individual specific, and the impacts are generally small):
Other non-podcast sources:
This is a fantastic overview of sex differences in training and metabolism. The key point (in terms of endurance sports) is that the most significant differences are related to sex hormones, and that women tend to be more metabolically suited for endurance type work, where men may be more suited for very short intense (non-aerobic) bursts. Most other differences in performance tend to be related to body size and body composition. This article is a great read for a general overview:https://www.strongerbyscience.com/gender-differences-in-training-and-diet/

Super deep dive into “a” theory on improving CV performance, if it is a limiter. This is a 4 part series. This can be slow at times, but an interesting opinion… but you really have to be willing to get through a lot of technical talk:

Strength.
A cyclist’s guide to the weight room: https://www.fasttalklabs.com/fast-talk/a-cyclists-guide-to-the-weight-room/
Tendon strength / health. This is a great podcast. Although the focus is on health / repair strategies (which are often the cause of injuries), Keith also gets into strength training and into the likely causes of interference signalling between endurance and strength. He discusses conceptually the best order to optimize gains (endurance then strength): https://hubhopper.com/episode/177-training-tendons-with-keith-baar-1579467702
This cycling coach gets further into Keith Baar’s studies, and discusses practicaly application of mixing strength & endurance training. Worth the listen: https://www.empiricalcycling.com/podcast-episodes/watts-doc-5-can-you-lift-heavy-while-endurance-training
Here is an alternative discussion on research into collagen specifically (related to tendon health). The key point here was collagen may not provide any unique benefit over other proteins, that are high quality overall. http://fuelthepedal.libsyn.com/ftp-20-sara-oikawa-phd-new-developments-in-collagen-research-implications-for-endurance-athletes
Cardiovascular / Heart.
Can extreme exercise damage the heart? This is a topic that tends to get a lot of press, maybe in a disproportionate amount. This is a great podcast on cardiovascular adaptations, and what has been observed in studies: https://podcasts.apple.com/us/podcast/inside-exercise/id1631457776?i=1000574523959&fbclid=IwAR0babBgwkA4Mp5lijC5yKvMgmbzJAaHhTECp56xJiGw5K6NUjnHhKIYXaY
This study discusses how endurance training (and high intensity training) impacts the heart. It gets into a deeper dive of the impact on the right ventricle, and how this may increase risk of AFib. Overall, it advocates a balanced approach on the topic, in that the benefits of cardiovascular health outweigh the risk of arrhythmias. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5353418/
This podcast discusses the potential negative impact of ultrarunning with Nick Tiller as an expanded discussion of his paper. They cover cardiovascular impact, and discuss right ventricle maladaptation and links to AFib. Key discussion:
Discuss Haywire Heart book, and how the title is a bit misleading… shock value. Nick’s paper is more balanced… exercise is good, while for some, a lot of exercise “may” have negative impact. The problem is there is no single threshold (e.g. over X hours you have problems). One study of people averaging 30 hours a week of exercise showed no adverse cardiovascular impact or mortality as a whole.
Discuss potential negative impact on lung function, heart, kidneys and muscular systems. In particular, some of the discussion revolved around single/multi-day events rather than regular training.
Discussed how detrimental NSAIDs were, and they should NOT be used in exercise.

Muscle Fiber / Training.
A fascinating study on identical twins, and how different their bodies were based on being trained / or untrained, over time. The key message is how adaptable fiber type is, and how the trained twin had significantly more slow-twitch (type I) fibers, whereas the sedentary twin had much more fast-twitch fibers (type IIa / IIx and hybrids): https://www.researchgate.net/publication/326398362_Muscle_health_and_performance_in_monozygotic_twins_with_30_years_of_discordant_exercise_habits
