本研究旨在调查半铁人三项赛期间压力袜预防肌肉损伤和保持肌肉表现的有效性。36 名经验丰富的铁人三项运动员自愿参加了这项研究。参与者根据年龄、人体测量数据和训练状态进行匹配，并被分为实验组（N = 19；使用从脚踝到膝盖的分级压力袜）或对照组（N = 17；使用普通袜子）。参与者在 29 +/- A 3 A 摄氏度和 73 +/- A 8 % 相对湿度下参加了半铁人三项赛。比赛时间通过芯片计时来测量。赛前和赛后，在反向运动跳跃期间测量最大高度和腿部肌肉力量。同时，测定血液肌红蛋白和肌酸激酶浓度，并使用经过验证的量表询问铁人三项运动员感知的用力和肌肉酸痛。各组之间的总比赛时间没有差异（对照组为 315 +/- A 45 分钟，实验组为 310 +/- A 32 分钟；P = 0.46）。比赛结束后，各组之间的跳跃高度（-8.5 +/- A 3.0 对比 -9.2 +/- A 5.3 %；P = 0.47）和腿部肌肉力量下降（-13 +/- A 10 对比 -15 +/- A 10 %；P = 0.72）相似。赛后肌红蛋白（718 +/- A 119 对比 591 +/- A 100 μg/mL；P = 0.42）和肌酸激酶浓度（604 +/- A 137 对比 525 +/- A 69 U/L；P = 0.60）在组间没有差异。赛后各组之间感知的肌肉酸痛（5.3 +/- A 2.1 对比 6.0 +/- A 2.0 任意单位；P = 0.42）和感知努力程度评分（17 +/- A 2 对比 17 +/- A 2 任意单位；P = 0.58）没有差异。在铁人三项比赛期间，穿着压力袜对于维持肌肉功能或减少肌肉损伤的血液标志物并不具有任何优势。
This study aimed at investigating the effectiveness of compression stockings to prevent muscular damage and preserve muscular performance during a half-ironman triathlon.Thirty-six experienced triathletes volunteered for this study. Participants were matched for age, anthropometric data and training status and placed into the experimental group (N = 19; using ankle-to-knee graduated compression stockings) or control group (N = 17; using regular socks). Participants competed in a half-ironman triathlon celebrated at 29 +/- A 3 A degrees C and 73 +/- A 8 % of relative humidity. Race time was measured by means of chip timing. Pre- and post-race, maximal height and leg muscle power were measured during a countermovement jump. At the same time, blood myoglobin and creatine kinase concentrations were determined and the triathletes were asked for perceived exertion and muscle soreness using validated scales.Total race time was not different between groups (315 +/- A 45 for the control group and 310 +/- A 32 min for the experimental group; P = 0.46). After the race, jump height (-8.5 +/- A 3.0 versus -9.2 +/- A 5.3 %; P = 0.47) and leg muscle power reductions (-13 +/- A 10 versus -15 +/- A 10 %; P = 0.72) were similar between groups. Post-race myoglobin (718 +/- A 119 versus 591 +/- A 100 mu g/mL; P = 0.42) and creatine kinase concentrations (604 +/- A 137 versus 525 +/- A 69 U/L; P = 0.60) were not different between groups. Perceived muscle soreness (5.3 +/- A 2.1 versus 6.0 +/- A 2.0 arbitrary units; P = 0.42) and the rating of perceived effort (17 +/- A 2 versus 17 +/- A 2 arbitrary units; P = 0.58) were not different between groups after the race.Wearing compression stockings did not represent any advantage for maintaining muscle function or reducing blood markers of muscle damage during a triathlon event.
