The purpose was to assess differences in postural response characteristics between two groups of elite athletes having power or endurance training. Participants were all men and included power- (M age = 21 yr., SD = 3, n = 12) and endurance-trained (M age = 22, SD = 3, n = 12) athletes. Muscle response characteristics and center of pressure measures were recorded during recovery from Fast (10 cm at 80 cm/sec.) and Slow (10 cm at 20 cm/sec.) horizontal platform perturbations. In response to Fast perturbations, power-trained athletes responded with significantly shorter times to stabilize the center of pressure, shorter muscle-contraction onset times, and larger muscle response amplitudes than endurance-trained athletes. This suggests power-trained athletes are more effective than endurance-trained athletes in responding to balance threats such as slips and trips in daily life and that power training should be studied to improve balance control of balance-impaired populations.
目的是评估具有力量或耐力训练的两组精英运动员在姿势反应特征方面的差异。参与者均为男性，包括力量训练组（M 年龄=21 岁，SD=3，n=12）和耐力训练组（M 年龄=22 岁，SD=3，n=12）运动员。在从 Fast（80cm/sec 时 10cm）和 Slow（20cm/sec 时 10cm）水平平台扰动中恢复时，记录肌肉反应特征和中心压力测量值。Fast 扰动时，力量训练组运动员稳定中心压力的时间明显更短，肌肉收缩起始时间更短，肌肉反应幅度更大，这表明力量训练组运动员比耐力训练组运动员更有效地应对日常生活中的滑倒和绊倒等平衡威胁，应研究力量训练以改善平衡受损人群的平衡控制。
