In this episode, I (Laurent Bannock) discuss "Energy Availability: From Health to Performance" with Jose Areta PhD, Liverpool John Moores University, UK). Discussion Topics Include: Energy Availability (EA): an overview Energy Balance, Energy Deficit, and Energy Availability  EA and impact on training adaptions incl down-regulation of skeletal muscle protein synthesis and autophagy EA and impact on health (incl menstrual function and bone metabolism) Case study of an athlete in chronic low energy availability Training with low carbohydrate availability AND low energy availability Key Paper(s) Discussed / Referred to: Skeletal muscle glycogen content at rest and during endurance exercise in humans: a meta-analysis Effects of sleeping with reduced carbohydrate availability on acute training responses Case study: Resumption of eumenorrhea in parallel with high training load after 4 years of menstrual dysfunction: a 5-year follow-up of an elite female cyclist Modulation of autophagy signaling with resistance exercise and protein ingestion following short-term energy deficit Related Podcast Episodes: #132 - "Nutrition and Athlete Bone Health" with Prof Craig Sale and Dr Kirsty Elliot-Sale #121 - "Protein and Endurance Athletes" with Dan Moore PhD #119 - "Fuel for the Work Required" with Mark Hearris PhD(c) #106 - "The Female Athlete" with Dr Kirsty Elliot-Sale #51 - 'Carbohydrate Availability & Training Adaptation' with Professor John Hawley #17 - 'Carbohydrates' with James Morton PhD Check out our other podcasts, publications, events, and professional education programs for current and aspiring sports nutritionists at www.TheIOPN.com and follow our social media outputs via @TheIOPN
