Recent meta-analyses on compression garments have reported faster recovery of muscle function particularly after intense eccentric power or resistance exercise. However, due to the complex interaction between cohorts included, exercises involved and compression applied, recovery length and modalities, and outcome parameters selected, only limited practical recommendations can be drawn from these studies. Thus, our aim was to determine the effect of compression tights on recovery from high mechanical and metabolic stress monitored over a longer recovery period.
Using a crossover design, 19 resistance-trained 4/5 Division German handball players (31.3±7.7 years; 24.1±3.8 kg/m) were randomly assigned at the start of the project to the compression tight (recovery-pro-tights, cep, Bayreuth, Germany) or the control group. Immediately after a combined lower extremity resistance training and electromyostimulation, participants had to wear compression tights. Compression was applied initially for 24 h and then 12 h intermitted by 12 h of nonuse for a total of 96 h. Primary study endpoint was maximum isokinetic hip/leg-extensor strength (MIES) as determined by a leg-press. Secondary endpoint was lower extremity power as assessed by a counter movement jump. Follow-up assessments were conducted 24, 48, 72, and 96 h postexercise. Outcomes were analyzed using a linear mixed effect model with spherical symmetric within-condition correlation.
All 19 participants underwent their allocated treatment and passed through the project strictly according to the study protocol. MIES demonstrated significantly (p=0.003) lower overall reductions (155 N) after wearing compression tights. In parallel, lower extremity power significantly (p<0.001) varies between both conditions with lower reductions in favor of the compression condition. Of importance, full recovery for lower extremity muscle strength or power was still not reached 96 h postexercise.
Based on our results we recommend athletes wear compression tights for faster recovery, particularly after intense exercise with a pronounced eccentric aspect.
近期关于压缩服装的荟萃分析报告称，肌肉功能恢复更快，尤其是在进行高强度离心力量或阻力训练之后。然而，由于纳入的队列、所涉及的运动、施加的压力、恢复时长和方式以及所选的结果参数之间存在复杂的相互作用，从这些研究中只能得出有限的实用建议。因此，我们的目的是确定压缩紧身裤对在较长恢复期内监测到的高机械和代谢应激恢复的影响。
采用交叉设计，19名经过阻力训练的德国手球4/5级运动员（年龄31.3±7.7岁；体重指数24.1±3.8kg/m）在项目开始时被随机分配到压缩紧身裤组（恢复专业紧身裤，cep，德国拜罗伊特）或对照组。在进行下肢联合阻力训练和肌电刺激后，参与者必须立即穿上压缩紧身裤。最初施加压力24小时然后间歇12小时（不使用12小时），共96小时。主要研究终点是通过腿举测定的最大等速髋/腿伸肌力量（MIES）。次要终点是通过反向移动跳评估的下肢功率。在运动后24、48、72和96小时进行随访评估。使用具有球对称条件内相关性的线性混合效应模型分析结果。
所有19名参与者都接受了分配的治疗，并严格按照研究方案完成了项目。穿着压缩紧身裤后，MIES总体下降幅度显著较小（155牛）（p = 0.003）。同时，两种情况下下肢功率显著不同（p < 0.001），压缩条件下下降幅度较小。重要的是，运动后96小时下肢肌肉力量或功率仍未完全恢复。
根据我们的结果，我们建议运动员穿着压缩紧身裤以加快恢复，特别是在具有明显离心成分的剧烈运动之后。
