How important is the interval in high-intensity interval training? What is the main finding and its importance? The intermittent nature of high-intensity interval training (HIIT) is important for maximizing skeletal muscle adaptations to this type of exercise, at least when a relatively small total volume of work is performed in an "all out" manner. The protein signalling responses to an acute bout of HIIT were generally not predictive of training-induced outcomes. Nonetheless, a single session of exercise lasting
