Fasting, Heat and Do Endurance Athletes Have more Daughters?

We have a special guest host this week, Kristi Storoschuk joins the podcast again to help David while Xylon is away. After a listener question on fueling they jump into some research. They discuss some fascinating papers including the impact of heat on carbohydrate and glycogen utilisation rates, the effects of a 7 day fast on performance and a paper looking at whether endurance athletes have more daughters. They then step into Kristi’s world and look at a paper on mitochondria and why they are more than just the powerhouses of the cell!  (00:00) Introduction(00:44) Medical Question(01:40) Kristi’s Madeira Trip(02:38) Kristi’s PhD Update(03:29) Kristi’s Training Update (06:01) Community Shoutouts Listener Question on Fueling(13:21) Heat and Dehydration’s Impact on Carbohydrate & Glycogen Use (24:10) Effect of Sport on Sex of Offspring(32:04) Performance Impacts of 7 Days of Fasting(45:04) MitochondriaThanks 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/onepercentfuelplannerThanks also to Stryd for their sponsorship, check out Stryd:Stryd helps you optimize your training and racing by measuring your running power, providing real-time data to improve efficiency, pace, and performance on any terrain.
