PURPOSE: This study compared ankle joint exercise and thigh exercise on the isometric strength of the lower limb and balance ability.
METHODS: Twenty-seven subjects were divided into ankle joint exercise (AEG, n=9), tight exercise (TEG, n=9), and control group (CON, n=9). AEG and TEG performed ankle joint and tight exercises three times a week for four weeks. The following were measured before and four weeks after each exercise: isometric strength at knee flexion and extension of the lower limb; isometric strength at ankle plantar flexion and dorsiflexion of the lower limb; static balance of trace length and C90 area; and the dynamic forward, backward, leftward, and rightward balance for each region.
RESULTS: The results showed that the isometric strength of plantar flexion (p<.05) was increased significantly in AEG compared to those in TEG and CON. The dynamic leftward (p<.05) and rightward balance (p<.05) were increased significantly in both AEG and TEG compared to that in CON. On the other hand, the static balance of the trace length and C90 area, isometric strength of ankle dorsiflexion, knee flexion and extension of the lower limb, and dynamic forward and backward balance did not show significant differences between the groups.
CONCLUSION: Ankle joint exercise improves the isometric strength of plantar flexion compared to tight exercise.
