This study investigated the effects of custom-fitted compression garments (CG) worn during recovery over a multi-day training camp in elite judo players (judoka). A single blind, placebo-controlled study was carried out in 11 elite judoka, using a two-way crossover design. Two three-day training camps were completed in CG and placebo conditions in a random order. Changes in performance and physiological markers were compared between conditions. Judoka were assessed before training for (maximal) isometric knee extension and grip strength, countermovement jump performance and bench-press velocity, alongside soreness, limb circumferences, plasma creatine kinase activity (CK) and perceived bruising. Measurements were repeated after 12, 36 and 43 h of training, whereupon judoka rated the effectiveness of each intervention. Knee extension and bench-press performance demonstrated significant familiarization ( < 0.001), and were excluded from subsequent analysis. Jump performance was unaffected by training (> 0.05). Grip strength declined throughout training (< 0.001), with peak decrements of -9.7% indicating mild muscle damage. Increases in bruising, CK and soreness demonstrated highly variable, if significant (< 0.001) responses. Although CG were perceived as significantly more effective than placebo for recovery (= 0.046), no effects were observed for any other outcome (> 0.05). Compression conferred no statistically significant impact upon recovery markers in elite judoka throughout training. Muscle damage responses were inconsistent in this population. Individual athletes would be advised to monitor habitually-used performance measures while using CG to ascertain whether perceptual benefits translate into enhanced recovery.Compression garments were perceived as more effective for recovery than placebo by elite judoka.However, no measures of performance or muscle damage were enhanced by CG.Randori was associated with inconsistent muscle damage responses in elite judoka, while lower-body performance was not impaired.Individual athletes would be advised to monitor habitually-used performance measures while using CG to ascertain whether perceptual benefits translate into enhanced recovery.
本研究调查了精英柔道运动员（柔道选手）在多日训练营恢复期间穿着定制压缩服装（CG）的效果。在11名精英柔道选手中进行了一项单盲、安慰剂对照研究，采用双向交叉设计。以随机顺序在CG和安慰剂条件下完成了两个为期三天的训练营。比较了不同条件下的运动表现和生理指标变化。在训练前评估柔道选手的（最大）等长膝关节伸展和握力、反向移动跳跃表现和卧推速度，以及酸痛感、肢体周长、血浆肌酸激酶活性（CK）和瘀伤感知。在训练12、36和43小时后重复测量，届时柔道选手对每种干预措施的有效性进行评分。膝关节伸展和卧推表现显示出显著的适应性（<0.001），并被排除在后续分析之外。跳跃表现不受训练影响（>0.05）。握力在整个训练过程中下降（<0.001），峰值下降-9.7%表明有轻度肌肉损伤。瘀伤、CK和酸痛感的增加显示出高度可变但显著的反应（<0.001）。尽管CG被认为在恢复方面比安慰剂显著更有效（=0.046），但在任何其他结果中均未观察到效果（>0.05）。在整个训练过程中，压缩对精英柔道选手的恢复指标没有统计学上的显著影响。该人群的肌肉损伤反应不一致。建议个体运动员在使用CG时习惯性地监测常用的运动表现指标，以确定感知到的益处是否转化为更好的恢复。精英柔道选手认为压缩服装在恢复方面比安慰剂更有效。然而，CG并没有提高运动表现或肌肉损伤的测量指标。自由对打与精英柔道选手不一致的肌肉损伤反应相关，而下半身表现未受损害。建议个体运动员在使用CG时习惯性地监测常用的运动表现指标，以确定感知到的益处是否转化为更好的恢复。
