The objective of this work was to determine the dynamics of maximal anaerobic power (MAP) of the lower limbs, following a single whole body cryostimulation treatment (WBC), in relation to the temperature of thigh muscles.
The subjects included 15 men and 15 women with an average age (± SD) of 21.6 ± 1.2 years. To evaluate the level of anaerobic power, the Wingate test was applied. The subjects were submitted to 6 WBC treatments at -130°C once a day. After each session they performed a single Wingate test in the 15, 30, 45, 60, 75 and 90th min after leaving the cryogenic chamber. The order of the test was randomized. All Wingate tests were preceded by an evaluation of thigh surface temperature with the use of a thermovisual camera.
The average thigh surface temperature (T(av)) in both men and women dropped significantly after the whole body cryostimulation treatment, and next increased gradually. In women T(av) remained decreased for 75 min, whereas in men it did not return to the basal level until 90th min. A statistically insignificant decrease in MAP was observed in women after WBC. On the contrary, a non-significant increase in MAP was observed in men. The course of changes in MAP following the treatment was similar in both sexes to the changes in thigh surface temperature, with the exception of the period between 15th and 30th min. The shorter time to obtain MAP was observed in women till 90th min and in men till 45 min after WBC compared to the initial level.
A single whole body cryostimulation may have a minor influence on short-term physical performance of supramaximal intensity, but it leads to improvement of velocity during the start as evidenced by shorter time required to obtain MAP.
本研究旨在确定单次全身冷冻刺激（WBC）后大腿肌肉温度与下肢最大无氧功率（MAP）的变化关系。
共纳入 15 名男性和 15 名女性受试者，平均年龄（±标准差）为 21.6±1.2 岁。采用测功计试验评估无氧功率。受试者每天接受 6 次-130°C 的 WBC 治疗。每次治疗后，受试者在离开冷冻室后的 15、30、45、60、75 和 90 分钟时进行单次测功计试验。测试顺序随机安排。所有测功计试验前均使用热像仪评估大腿表面温度。
男性和女性的平均大腿表面温度（T（av））在全身冷冻刺激治疗后均显著下降，随后逐渐升高。女性 T（av）在 75 分钟内持续下降，而男性直到 90 分钟才恢复到基础水平。女性在 WBC 后 MAP 出现了统计学上无意义的下降。相反，男性的 MAP 出现了非显著的增加。除了 15 至 30 分钟之间的时间段外，女性和男性 MAP 变化的趋势与大腿表面温度的变化相似。与初始水平相比，女性在 WBC 后 90 分钟内达到 MAP 的时间更短，而男性在 45 分钟内达到 MAP 的时间更短。
单次全身冷冻刺激可能对超最大强度的短期身体表现产生较小影响，但会导致启动速度的提高，表现为达到 MAP 所需的时间更短。
