Previous studies have shown that time-dependent cardiorespiratory responses before and after the onset of dynamic exercise at various intensities depend on the relationship between exercise training and its exercise intensity. However, it is not clear when and to what extent such differences in training intensity for the development of short- and long-term physiological adaptations affect cardiorespiratory function during exercise. The subjects were 16 college student athletes who were divided into 95% and 80% intensity training groups. After HIT, maximal oxygen uptake increased significantly in both groups. After HIT, maximal heart rate during step exercise increased significantly only in the 95% training group after HIT after 6 weeks, and an increase in heart rate immediately after the start of exercise was observed after HIT. We concluded that HIT intensity-dependent adaptive changes in cardiorespiratory function during exercise appear mainly in the cardiovascular system after 6 weeks.
