Ground reaction force characteristics during each subject group in mean (standard deviation).

BW = body weight; η2 = partial eta squared; β = observed power. Significant P-values (< 0.05) are shown in bold. (raw data found in S1 File).BW即体重（body weight）；η2为偏Eta平方（partial eta squared）；β为观测功效（observed power）。P值小于0.05的显著性结果以粗体显示。原始数据详见S1文件。
