目的：检查全身冷冻疗法（WBC）方案（-110 ℃下3分钟）对热中性环境中高强度间歇性运动期间急性恢复和耐力表现关键变量的影响。研究方法：11名耐力运动员在随机交叉设计中进行了两次测试，其中5 x 5分钟的高强度跑步（HIR）之后是1小时的被动休息，温度接近22 ℃，包括3分钟的全身暴露于-110 ℃（WBC）或3分钟步行（PBO）的安慰剂干预。在HIR之前（R1）和1小时恢复期之后（R2）执行斜坡测试方案。沿着股肌氧含量的变化，测量至力竭时间（t（lim））。在次最大和最大跑步过程中，侧肌（TSI）、氧消耗量（VO 2）、毛细血管血乳酸、心率（HR）和感知用力等级（RPE）。结果：R1和R2之间t（lim）的差异在WBC中低于PBO（P <0.05，效应量d = 1.13）。在R2期间，亚极量和极量跑期间的白细胞TSI较高（P <0.01，d = 0.68-1.01）。此外，WBC后次最大R2水平下的VO 2、HR和RPE低于PBO（P= 0.04至0.05）。
Purpose: To examine the effects of a whole-body cryotherapy (WBC) protocol (3 min at -110 degrees C) on acute recovery and key variables of endurance performance during high-intensity intermittent exercise in a thermoneutral environment. Methods: Eleven endurance athletes were tested twice in a randomized crossover design in which 5 x 5 min of high-intensity running (HIR) were followed by 1 h of passive rest at similar to 22 degrees C, including either 3 min of whole-body exposure to -110 degrees C (WBC) or a placebo intervention of 3 min walking (PBO). A ramp-test protocol was performed before HIR (R1) and after the 1-h recovery period (R2). Time to exhaustion (t(lim)) was measured along with alterations in oxygen content of the vastus. lateralis (TSI), oxygen consumption (VO2), capillary blood lactate, heart rate (HR), and rating of perceived exertion (RPE) during submaximal and maximal running. Results: The difference in t(lim), between R1 and R2 was lower in WBC than in PBO (P < .05, effect size d = 1.13). During R2, TSI was higher in WBC during submaximal and maximal running (P < .01, d = 0.68-1.01). In addition, VO2, HR, and RPE were lower at submaximal level of R2 after WBC than in PBO (P=.04 to
