Abstract

Purpose: Power output at the moderate-to-heavy intensity transition decreases during prolonged exercise. Resilience to this has been termed ‘durability’. The relationship between durability and performance, and the mechanistic determinants of durability, are not well-characterised. The purpose of th...
