The aim of the present investigation was to determine whether using cryostimulation (partial-body cryostimulation) impacts sleep quality in professional soccer players. Different exposure durations at - 180 °C were tested randomly after standardized training sessions in nine professional soccer players (no cryostimulation, 180-s exposure, two 90-s exposures separated by a 5-min rest at room temperature, and 90-s exposure), and the effects on sleep quality using 3-dimensional accelerometers worn during sleep were assessed.
The number of movements during the night after partial-body cryostimulation was significantly reduced only in the 180-s exposure condition (p < 0.05, very large effect size) compared with the control condition. Partial-body cryostimulation seems to induce a positive impact on sleep quality that may be dose-dependent.

本研究旨在确定使用冷冻刺激（局部身体冷冻刺激）是否会影响职业足球运动员的睡眠质量。在九名职业足球运动员进行标准化训练后，随机测试了在-180°C下不同的暴露持续时间（无冷冻刺激、180秒暴露、两次90秒暴露，中间在室温下休息5分钟，以及90秒暴露），并使用睡眠期间佩戴的三维加速度计评估了对睡眠质量的影响。
与对照条件相比，仅在180秒暴露条件下，局部身体冷冻刺激后夜间的运动次数显著减少（p<0.05，效应量非常大）。局部身体冷冻刺激似乎对睡眠质量有积极影响，且可能存在剂量依赖性。试验注册澳大利亚和新西兰临床试验注册中心（ANZCTR），ACTRN12619000330145，注册日期：2019年3月4日。回顾性注册。
