Episode overview:

Ed Maunder PhD is an exercise physiologist with expertise in metabolic responses to endurance exercise, and metabolic adaptations to endurance training. Ed is a Lecturer in the School of Sport and Recreation and part of the Sport Physiology and Nutrition Research Group at SPRINZ. His research is focused on understanding the physiological drivers of mitochondrial adaptation to endurance exercise, and the physiological profiling of endurance athletes.

Episode highlights:

(13:42) Lactate threshold durability: before and after 2.5 hours of cycling, average decrease of 10%, athletes saw reduced efficiency and reduced energy expenditure, decreasing efficiency is likely even more of a factor in running

(35:37) Training durability: speculation, training specificity to durability, creating stress early during long runs

(44:44) Takeaways: interpreting research on training interventions, arranging training structure intensity-first versus intensity-last, specificity of durability training
