Brief Summary:
The purpose of this study is to investigate the acute effects of different intensities (i.e., 50, 75, and 100% of maximal anaerobic power) of 4-s sprint interval exercise on physiological responses. Secondly, it will determine the relationship between intensity and recovery duration (i.e., 15, 30, or 45-s) that will stimulate the cardiovascular and metabolic systems.
Detailed Description:
Background Short sprint interval training (sSIT) is typically performed at maximal intensity, generating power far above what is needed to reach peak oxygen consumption (VO₂peak). However, the physiological effects of submaximal sprint intensities and different recovery periods are not well understood.
Study Aim This study examined how power output and oxygen consumption (VO₂) respond to repeated 4-second sprints at 50%, 75%, and 100% of maximal power (Pmax) with rest periods of 15, 30, or 45 seconds.
Methods Eleven recreationally active participants completed nine trials, each consisting of thirty 4-second cycling sprints under different intensity and recovery conditions.
