. Study of recovery kinetics following SEPT would facilitate the optimization of its frequency during a microcycle. Therefore, this study aimed to (1) determine the recovery kinetics of fatigue, EIMD, and performance following SEPT; (2) examine whether work-to-rest ratio of SEPT affects recovery kinetics

The transition from rest to exercise mandates an immediate increase in skeletal-muscle contractile activity and ATP turnover. In contrast, the rate of pulmonary oxygen uptake ( V ˙ O 2 ) increases with exponential response kinetics, 1 which closely reflects the kinetics of muscle V ˙ O 2 , 2

Pulmonary oxygen uptake kinetics (VO 2 kinetics) is considered a noninvasive measure of an athlete’s capacity to utilize O 2 and respond to variations in energy demands. It is an important assessment of an athlete’s integrative physiological response 1 in both endurance sports 2 , 3 and team
