The aim was to examine certain aspects of circulatory, metabolic, hormonal, thermoregulatory, cognitive, and perceptual responses while sitting following a brief session of high-intensity interval exercise. Twelve students (five men; age, 22 ± 2 years) performed two trials involving either simply sitting for 180 min (SIT) or sitting for this same period with a 6-min session of high-intensity exercise after 60 min (SIT+HIIT). At T (after 30 min of resting), T (after a 20-min breakfast), T (after sitting for 1 h), T (immediately after the HIIT), T, T, T, and T (30, 60, 90, and 120 min after the HIIT), circulatory, metabolic, hormonal, thermoregulatory, cognitive, and perceptual responses were assessed. The blood lactate concentration (at T-T), heart rate (at T-T), oxygen uptake (at T-T), respiratory exchange ratio, and sensations of heat (T-T), sweating (T, T) and odor (T), as well as perception of vigor (T-T), were higher and the respiratory exchange ratio (T-T) and mean body and skin temperatures (T) lower in the SIT+HIIT than the SIT trial. Levels of blood glucose and salivary cortisol, cerebral oxygenation, and feelings of anxiety/depression, fatigue or hostility, as well as the variables of cognitive function assessed by the Stroop test did not differ between SIT and SIT+HIIT. In conclusion, interruption of prolonged sitting with a 6-min session of HIIT induced more pronounced circulatory and metabolic responses and improved certain aspects of perception, without affecting selected hormonal, thermoregulatory or cognitive functions.
目的是在进行一小段高强度间歇运动后就坐时，检查循环、代谢、激素、体温调节、认知和感知反应的某些方面。12名学生（5名男性；年龄22±2岁）进行了两项试验，一项是单纯就坐180分钟（SIT），另一项是在60分钟后进行6分钟的高强度运动，然后同样就坐180分钟（SIT+HIIT）。在T（休息30分钟后）、T（进食20分钟早餐后）、T（就坐1小时后）、T（高强度间歇运动后即刻）、T、T、T和T（高强度间歇运动后30、60、90和120分钟）时，评估循环、代谢、激素、体温调节、认知和感知反应。与SIT试验相比，SIT+HIIT组的血乳酸浓度（在T-T）、心率（在T-T）、摄氧量（在T-T）、呼吸交换率以及热感（T-T）、出汗（T、T）和气味感（T）更高，而呼吸交换率（T-T）以及平均体温和皮肤温度（T）更低。SIT和SIT+HIIT组之间的血糖和唾液皮质醇水平、脑氧合以及焦虑/抑郁、疲劳或敌意感，以及通过斯特鲁普测试评估的认知功能变量没有差异。总之，用6分钟的高强度间歇运动打断长时间就坐会引起更明显的循环和代谢反应，并改善感知的某些方面，而不影响所选的激素、体温调节或认知功能。
