Dynamic balance	SA (mm²)	31.0 ± 8.7	21.9 ± 3.1	33.2 ± 9.3	36.1 ± 6.8***^##
	SL (cm)	24.8 ± 4.1	16.0 ± 2.3***	23.0 ± 2.6	11.0 ± 1.9***^##

The Wilcoxon test was conducted to compare differences between before and after exercise in each group (**p<0.01; ***p<0.001). The Mann-Whiteny U test was performed to compare differences between the two groups (#p<0.05; ##p<0.01). SA, sway area; SL, sway length; SS, sway speed.
