High-intensity interval training (HIIT) performed in an "all-out" manner (e.g., repeated Wingate Tests) is a time-efficient strategy to induce skeletal muscle remodelling towards a more oxidative phenotype. A fundamental question that remains unclear, however, is whether the intermittent or "pulsed" nature of the stimulus is critical to the adaptive response. ...
