目的：研究在长时间跑步中穿着不同身体覆盖面积的下半身压缩衣对运动能力和肌肉损伤的影响。研究方法：30名男性受试者被随机分配到三组之一：（1）穿着大腿15 mmHg的压缩紧身衣[n = 10，CT组]，（2）穿着小腿15 mmHg的压缩袜[n = 10，CS组]，和（3）穿着大腿和小腿< 5 mmHg的下身服装[n = 10，CON组]。该运动包括120分钟的上坡跑步，最大氧浓度为55%。心率（HR）、感知用力率（RPE）和跑步经济性运动前评价膝关节伸、跖屈最大自主收缩力（MVC）、反向运动跳跃高度（CMJ）、跳落高度（DJ）以及肌肉酸痛、疲劳主观感觉评分的变化，运动后60和180 min。分别于运动前（休息20 min后）、运动后60 min、运动后即刻、运动后60 min和180 min采集血样，测定血糖、乳酸、血清游离脂肪酸、肌红蛋白（Mb）、超敏C-反应蛋白和血浆白细胞介素-6浓度。结果：三组运动员在运动过程中心率、RPE和跑步经济性的变化无显著差异。运动后膝关节伸、跖屈和DJ的MVC显著降低，组间无差异。所有组的血清Mb浓度均随运动而显著增加，而运动后180 min期间，CT组Mb浓度曲线下面积（13，833 ± 1，397 pg/mL 180 min）显著低于CON组（24，343 ± 3，370 pg/mL 180 min，P = 0.03）。结论：在大腿上穿加压衣可显著降低运动后血清Mb浓度的升高，表明运动性肌肉损伤得到了减轻。
Purpose: To examine the effects of wearing a lower-body compression garment with different body coverage areas during prolonged running on exercise performance and muscle damage. Methods: Thirty male subjects were randomly assigned to one of three groups: (1) wearing a compression tights with 15 mmHg to thigh [n = 10, CT group], (2) wearing a compression socks with 15 mmHg to calf [n = 10, CS group], and (3) wearing a lower-body garment with < 5 mmHg to thigh and calf [n = 10, CON group]. The exercise consisted of 120 min of uphill running at 55% of O2max. Heart rate (HR), rate of perceived exertion (RPE), and running economy (evaluated by VO2) were monitored during exercise every 10 min. Changes in maximum voluntary contraction (MVC) of knee extension and plantar flexion, height of counter movement jump (CMJ) and drop jump (DJ), and scores of subjective feelings of muscle soreness and fatigue were evaluated before exercise, and 60 and 180 min after exercise. Blood samples were collected to determine blood glucose, lactate, serum free fatty acid, myoglobin (Mb), high-sensitivity C-reactive protein, and plasma interleukin-6 concentrations before exercise (after 20 min of rest), at 60 min of exercise, immediately after exercise, and 60 and 180 min after exercise. Results: Changes in HR, RPE, and running economy during exercise did not differ significantly among the three groups. MVC of knee extension and plantar flexion, and DJ decreased significantly following exercise, with no difference among groups. The serum Mb concentration increased significantly with exercise in all groups, whereas the area under the curve for Mb concentration during 180 min post-exercise was significantly lower in the CT group (13,833 ± 1,397 pg/mL 180 min) than in the CON group (24,343 ± 3,370 pg/mL 180 min, P = 0.03). Conclusion: Wearing compression garment on the thigh significantly attenuated the increase in serum Mb concentration after exercise, suggesting that exercise-induced muscle damage was attenuated.
