This study investigated the acute effects of compression garments (CG) on balance control in elite athletes. 15 male professional handball players were recruited. They had to stand as motionless as possible in a monopedal stance on a force plate with the eyes closed and on a wobble board with the eyes open, while wearing CG or not. Centre of foot pressure mean velocity and surface area were calculated. Statistics were first calculated with the data from the whole sample. A hierarchical cluster analysis was also performed in order to categorize the participants' behaviours into subgroups with similar characteristics. The whole group analysis showed that there were no significant effects attributed to CG. The clustering analysis identified two distinct and homogeneous subgroups of participants. Only athletes with the best balance abilities at baseline could benefit from CG wearing to improve their balance control. These athletes, who swayed less and were more sensitive to somatosensory manipulation due to CG wearing, seem to control balance by adopting a support-dependent preferred sensorimotor tactic. Our findings suggest that amongst high-level athletes, the ability to benefit from CG wearing to improve balance control seems to depend on participants' intrinsic balance skills and/or preferred sensorimotor tactics.
本研究调查了压缩服装(CG)对精英运动员平衡控制的急性影响。招募了 15 名男性职业手球运动员。他们必须在闭眼单足站立在测力板上和睁眼站在平衡板上尽可能保持不动,同时穿着 CG 或不穿。计算了足底压力的平均速度和表面积。首先用整个样本的数据进行了统计计算。还进行了层次聚类分析,以便根据参与者的相似特征将他们的行为分为不同的亚组。全组分析显示,CG 没有产生显著影响。聚类分析确定了两个截然不同且同质的参与者亚组。只有在基线时平衡能力最好的运动员才能从 CG 穿着中受益,从而改善他们的平衡控制。这些运动员由于 CG 的穿着而摆动幅度更小,对躯体感觉的操纵更敏感,他们似乎通过采用依赖支撑的首选感觉运动策略来控制平衡。我们的研究结果表明,在高水平运动员中,从 CG 穿着中受益以改善平衡控制的能力似乎取决于参与者的内在平衡技能和/或首选感觉运动策略。
