In this podcast Maddy talks to James Spragg, a cycling coach and physiologist, about energy systems. James talks through the different energy systems, the relationship between intensity and energy system contribution, takes a deep dive into the aerobic energy system and how to train it effectively, and talks about profiling our energy systems in order to inform training.Topics covered:1:30 - A bit about James and his journey in cycling, academia and coaching3:35 - James’ PhD7:30 - Overview of energy systems 13:06 - Energy systems are synergistic14:01 - The hyperbolic force-time relationship18:03 - The relationship between intensity and energy system contribution21: 40 - Cause of muscle fatigue27:45 - The aerobic system and sustainable exercise29:52 - The importance of capillarisation and training the aerobic system37:30 - Lactate.
