目的
本研究的目的是确定压缩衣是否可以改善间歇冲刺表现并辅助表现或自我报告的连续几天高强度训练的恢复情况。
方法
熟悉后，14 名男性橄榄球运动员进行了两种随机测试条件（穿或不穿衣服），涉及连续几天的模拟团队运动锻炼方案，每种条件下间隔 24 小时恢复，条件之间间隔 2 周。每天进行 80 分钟的高强度锻炼，锻炼表现由重复的 20 米冲刺和推车测功机（单人 Scrum 机）上的峰值功率决定。每天记录裸体重、心率、皮肤温度和鼓室温度以及血乳酸（La-）的测量结果；此外，每天和运动后 48 小时记录肌酸激酶 (CK) 和肌肉酸痛情况。
结果
在重复 20 米冲刺训练或推车测力计峰值功率的锻炼方案中，任何一天的条件之间不存在差异（P=0.20 至 0.40）。心率、鼓室温度和体重在不同条件下没有显着差异；然而，压缩衣下的皮肤温度较高。尽管 La- 或 CK 不存在差异 (P=.50)，但参与者在穿着服装后的运动后 48 小时内感觉肌肉酸痛水平降低（服装和对照组为 2.5+/-1.7 对比 3.5+/-2.1；P=.01）。
结论
使用压缩衣并没有改善或妨碍连续几天的模拟团队运动活动。尽管每天运动期间和运动后穿着服装可以减少自我报告的肌肉酸痛，但运动表现或恢复没有明显改善。
PURPOSE
The aim of this study was to determine whether compression garments improve intermittent-sprint performance and aid performance or self-reported recovery from high-intensity efforts on consecutive days.
METHODS
Following familiarization, 14 male rugby players performed two randomized testing conditions (with or without garments) involving consecutive days of a simulated team sport exercise protocol, separated by 24 h of recovery within each condition and 2 weeks between conditions. Each day involved an 80-min high-intensity exercise circuit, with exercise performance determined by repeated 20-m sprints and peak power on a cart dynamometer (single-man scrum machine). Measures of nude mass, heart rate, skin and tympanic temperature, and blood lactate (La-) were recorded throughout each day; also, creatine kinase (CK) and muscle soreness were recorded each day and 48 h following exercise.
RESULTS
No differences (P=.20 to 0.40) were present between conditions on either day of the exercise protocol for repeated 20-m sprint efforts or peak power on a cart dynamometer. Heart rate, tympanic temperature, and body mass did not significantly differ between conditions; however, skin temperature was higher under the compression garments. Although no differences (P=.50) in La- or CK were present, participants felt reduced levels of perceived muscle soreness in the ensuing 48 h postexercise when wearing the garments (2.5+/-1.7 vs 3.5+/-2.1 for garment and control; P=.01).
CONCLUSIONS
The use of compression garments did not improve or hamper simulated team-sport activity on consecutive days. Despite benefits of reduced self-reported muscle soreness when wearing garments during and following exercise each day, no improvements in performance or recovery were apparent.
