To detect the effect of a strenuous exercise on equilibrium and to quantify its time course.
Body sway area, sway path, and center of foot pressure were recorded in eight young able-bodied subjects, standing quietly with feet together, with eyes open (EO) and eyes closed (EC), on a dynamometric platform, before and after treadmill walking for 25min, during which subjects approached the maximum heart rate.
A significant increase in body sway was observed after exercise. It was present under both visual conditions and affected both sway area and sway path. Sway increased most in the initial few minutes (sway area EO=800.7mm2 [p < .005], EC=1,779.5mm2 [not significant]; sway path EO=545mm [p < .0001], EC=811.8mm [p < .05]) with respect to preexercise values (sway area EO=449.4mm2, EC=1,316.2mm2; sway path EO=369.5 mm, EC=652.5mm) and was followed by a plateau (sway area EO=609.9mm2, EC=1,567.9mm2; sway path EO=431.2mm, EC=710.9mm). Full recovery to basal values occurred within about 15min after the end of the exercise.
Body sway is affected by prolonged fatiguing exercise, such as strenuous walking. This effect is of moderate extent and vanishes within a few minutes.
检测剧烈运动对平衡的影响并对其时间进程进行量化。
在测力平台上，记录8名身体健全的年轻受试者在双脚并拢安静站立、睁眼（EO）和闭眼（EC）状态下，以及在跑步机上行走25分钟（期间受试者接近最大心率）前后的身体摆动面积、摆动路径和足底压力中心。
运动后观察到身体摆动显著增加。在两种视觉条件下均出现这种情况，且对摆动面积和摆动路径均有影响。与运动前值（摆动面积EO = 449.4mm²，EC = 1316.2mm²；摆动路径EO = 369.5mm，EC = 652.5mm）相比，最初几分钟内摆动增加最为明显（摆动面积EO = 800.7mm² [p < 0.005]，EC = 1779.5mm² [无显著性差异]；摆动路径EO = 545mm [p < 0.0001]，EC = 811.8mm [p < 0.05]），随后趋于平稳（摆动面积EO = 609.9mm²，EC = 1567.9mm²；摆动路径EO = 431.2mm，EC = 710.9mm）。运动结束后约15分钟内完全恢复至基础值。
身体摆动受长时间疲劳运动（如剧烈行走）的影响。这种影响程度适中，且在几分钟内消失。
