This is one of the first intervention studies to examine how low- (LIT) and high-intensity endurance training (HIT) affect durability, defined as 'time of onset and magnitude of deterioration in physiological-profiling characteristics over time during prolonged exercise'. Sedentary and recreationally active men (n = 16) and women (n = 19) completed either LIT (average weekly training time 6.8 0.
