PURPOSE
The purpose of the present study was to investigate the effect of whole-body cryotherapy (WBC) treatment after exercise on appetite regulation and energy intake.
METHODS
Twelve male athletes participated in two trials on different days. In both trials, participants performed high-intensity intermittent exercise. After 10 min following the completion of the exercise, they were exposed to a 3-min WBC treatment (-140 °C, WBC trial) or underwent a rest period (CON trial). Blood samples were collected to assess plasma acylated ghrelin, serum leptin, and other metabolic hormone concentrations. Respiratory gas parameters, skin temperature, and ratings of subjective variables were also measured after exercise. At 30 min post-exercise, energy and macronutrient intake were evaluated during an ad libitum buffet meal test.
RESULTS
Although appetite-regulating hormones (acylated ghrelin and leptin) significantly changed with exercise ( = 0.047 for acylated ghrelin and < 0.001 for leptin), no significant differences were observed between the trials. Energy intake during the buffet meal test was significantly higher in the WBC trial (1371 ± 481 kcal) than the CON trial (1106 ± 452 kcal, = 0.007).
CONCLUSION
Cold exposure using WBC following strenuous exercise increased energy intake in male athletes.
目的
本研究旨在探讨运动后全身冷疗（WBC）对食欲调节和能量摄入的影响。
方法
12 名男性运动员在不同的日子参加了两项试验。在两项试验中，参与者都进行了高强度间歇运动。运动完成后 10 分钟，他们接受了 3 分钟的 WBC 治疗（-140°C，WBC 试验）或休息（CON 试验）。采集血样以评估血浆酰化 ghrelin、血清瘦素和其他代谢激素浓度。运动后还测量了呼吸气体参数、皮肤温度和主观变量的评分。在运动后 30 分钟，进行了随意自助餐测试，评估能量和宏量营养素的摄入。
结果
尽管食欲调节激素（酰化 ghrelin 和瘦素）在运动后明显发生变化（酰化 ghrelin 的 = 0.047，瘦素的 < 0.001），但两个试验之间没有观察到显著差异。自助餐测试期间的能量摄入在 WBC 试验（1371 ± 481 kcal）中明显高于 CON 试验（1106 ± 452 kcal， = 0.007）。
结论
剧烈运动后使用 WBC 进行冷暴露会增加男性运动员的能量摄入。
