Effects of differential external pneumatic compression pressures on recovery and repeated sprint performance: a randomized placebo-controlled crossover study

This dataset contains the anonymized raw data supporting the study entitled "Effects of differential external pneumatic compression pressures on recovery and repeated sprint performance: a randomized placebo-controlled crossover study." Twelve recreationally trained men completed four experimental conditions in a randomized, single-blind, placebo-controlled crossover design: passive control (CON), placebo compression (PLA), external pneumatic compression at 90 mmHg, and external pneumatic compression at 190 mmHg. Each trial included a repeated-sprint cycling fatigue protocol, a 20-min condition-specific recovery intervention, a subsequent repeated-sprint performance test consisting of five 10-s maximal sprints separated by 60 s of passive recovery, and a final 30-min passive recovery period. The dataset includes participant characteristics, the number of sprints completed during the fatigue protocol, mean and peak power output, blood lactate concentration, mean arterial pressure, vastus lateralis muscle oxygen saturation, total hemoglobin, and rating of perceived exertion. Blood lactate, mean arterial pressure, and perceived exertion were assessed at predefined time points throughout the experimental protocol. Muscle oxygen saturation and total hemoglobin were recorded during each sprint and recovery interval of the repeated-sprint performance test and normalized to the trial-specific baseline value. All participant data have been anonymized.本数据集包含支撑题为《差异式外部气动加压压力对恢复与重复冲刺表现的影响：一项随机安慰剂对照交叉研究》的科研项目的匿名原始实验数据。 12名接受休闲训练的男性受试者采用随机单盲、安慰剂对照的交叉实验设计，完成了四类实验条件：被动对照组（passive control, CON）、假加压对照组（placebo compression, PLA）、90mmHg外部气动加压组，以及190mmHg外部气动加压组。每项实验流程均包含重复冲刺自行车疲劳方案、20分钟的针对性恢复干预、后续的重复冲刺表现测试——该测试由5次10秒全力冲刺组成，每次冲刺间隔60秒被动恢复——以及最终30分钟的被动恢复期。 本数据集涵盖受试者基线特征信息、疲劳方案中完成的冲刺总次数、平均功率输出与峰值功率输出、血乳酸浓度、平均动脉压、股外侧肌血氧饱和度、总血红蛋白含量，以及自觉劳累分级评分（rating of perceived exertion）。血乳酸浓度、平均动脉压与自觉劳累分级评分在整个实验流程的预设时间点进行评估。在重复冲刺表现测试的每次冲刺与恢复间隔期间，均记录了肌血氧饱和度与总血红蛋白含量，并将其标准化至对应实验的个体基线值。所有受试者的相关数据均已完成匿名化处理。
