Questioning Limiters in Endurance - Dr Andrew Koutnik

Another week another bunch of running records which we cover. After this we chat a bit about Tarawera Ultramarathon results and the Tyreek Hill vs Noah Lyles showdown before touching on a new form of doping - Mitochondrial Transplants. We then get to an interview with Dr Andrew Koutnik a researcher  studying the influence of nutrition and metabolism on health, disease, and performance about a paper he was an author on; “Carbohydrate Ingestion Eliminates Hypoglycemia & Improves Endurance Exercise Performance in Triathletes Adapted to Very Low & High Carbohydrate Isocaloric Diets”(00:00) Introduction(07:17) David’s Heat Training(10:15) Xylon Turns a Corner (14:00) Community Shoutouts (17:12) Indoor Track Records (21:30) New Half Marathon WR (26:16) Tarawera Results (29:50) Noah Lyles vs Tyreek Hill (32:40) Mitochondrial Transplants (40:30) Interview Starts(42:40) Importance of Science Communication (46:02) What Was Done in the Study? (48:20) Timeline of Adaptation to Low Carb Diets(53:05) Study Design (61:20) Findings of the Study (63:00) Study Population and Applicability (74:00) Metabolically Unhealthy Athletes (78:29) Outro and Review (84:40) Doctor’s Office (89:20) What We’ll Be Watching Thanks to Precision Fuel and Hydration for their sponsorship, use the link below to get 15% off your first order and support the podcast: https://visit.pfandh.com/theonepercentbetterpodcastIf you’re unsure how which products to use or how to plan your race nutrition check out Precision’s Fuel & Hydration Planner (if you follow this you will have your discount applied automatically on your first order too): https://visit.pfandh.com/onepercentfuelplannerLinks to Andrew: Instagram: @andrewkoutnikphdX: @AKoutnikArticle on Mitochondrial Transplantation as Dopinghttps://www.telegraph.co.uk/news/2025/02/14/new-doping-trick-why-scientists-fear-athletes-already-using/ David’s Article on Mitochondrial Transplantshttps://open.substack.com/pub/healthperformancenexus/p/mitochondrial-transplantationArticle Discussed with Andrew  https://journals.physiology.org/doi/full/10.1152/ajpcell.00583.2024 Article Andrew Mentioned on Runners https://www.frontiersin.org/journals/physiology/articles/10.3389/fphys.2023.1150265/fullArticle on Magnus Ditlev Andrew Mentionedhttps://journals.humankinetics.com/view/journals/ijspp/20/1/article-p161.xml Andrew’s in Depth Breakdown of the Paper on Substackhttps://substack.com/inbox/post/154543219?r=40eopm&utm_campaign=post&utm_medium=web&triedRedirect=true Submit topics, feedback or questions to us on Instagram via DM or to the email address: [email protected] us on Instagram:https://www.instagram.com/onepercentbetterpodFollow us on X:@PodOnepercent Join the Strava Group:https://www.strava.com/clubs/onepercentbetterpod Royalty Free Music from Tunetank.com Track: Trendy Style by PillowVibes https://tunetank.com/track/1027-trendy-style/
