The present study investigated the effects of a series of 10 whole-body cryostimulation (WBC) sessions (3 min; -110 °C) on physiological and thermal responses to a submaximal exercise test in 17 elite athletes. Participants performed an exercise test twice at similar levels of intensity before and after a series of ten WBC sessions. Before and during the test, each participant's oxygen uptake (VO), heart rate (HR), internal temperature (Ti), and skin temperature in selected areas of the skin were measured, and the mean arterial pressure (MAP), physiological strain index (PSI), and mean skin temperature (Tsk) were calculated. The results show that during exercise, increases in Ti and the PSI were significantly lower after the WBC sessions, and although there were no significant changes in HR or the MAP, the Tsk was significantly higher. Following exercise, an increase in skin temperature asymmetry over the lower-body muscles was detected. A series of WBC sessions induced a tendency toward a decrease in temperature asymmetry over the thigh muscles. In conclusion, a series of ten WBC sessions does not induce significant modifications in physiological variables but does influence the PSI and Ti during exercise. Moreover, a series of ten WBC sessions influences the distribution of skin temperature and the magnitude of temperature asymmetries in the early phase of recovery.
本研究调查了17名精英运动员接受10次全身冷冻刺激（WBC）疗程（每次3分钟，-110°C）对次最大运动测试的生理和热反应的影响。参与者在接受10次WBC疗程前后，以相似的强度水平进行了两次运动测试。在测试前和测试期间，测量了每位参与者的摄氧量（VO）、心率（HR）、体内温度（Ti）以及选定皮肤区域的皮肤温度，并计算了平均动脉压（MAP）、生理应变指数（PSI）和平均皮肤温度（Tsk）。结果显示，在运动期间，WBC疗程后Ti和PSI的升高显著降低，并且尽管HR或MAP没有显著变化，但Tsk显著升高。运动后，检测到下半身肌肉的皮肤温度不对称性增加。一系列WBC疗程导致大腿肌肉温度不对称性有降低的趋势。总之，10次WBC疗程不会引起生理变量的显著改变，但会在运动期间影响PSI和Ti。此外，10次WBC疗程会在恢复早期影响皮肤温度分布和温度不对称程度。
