Effects of Chinese fitness dancing on lower limb strength and fall risk in middle-aged and older women: A cross-sectional study.

Abstract

This study sought to identify the effect of Chinese fitness dancing on lower limb strength and fall risk in middle-aged and older women. The MicroFET3 portable muscle strength tester, the FreeStep test system, and tests to evaluate fall risk were used to measure the maximum muscle strength, fall risk index, and static balance ability of extensor muscle groups in the lower limbs. Compared with the irregular exercise group, the maximum muscle strength of extensor muscle groups in the lower limb, five sit-to-stand test timings, fall risk index, static balance ability, and lower limb flexibility did not improve significantly in the 1-year regular exercise group (p > 0.01). However, these indicators were significantly improved in the 10-year regular exercise group compared with the 1-year regular exercise group (p < 0.01). Long-term regular participation in Chinese fitness dancing significantly increased muscle strength in the lower limbs and effectively lowered the fall risk index in middle-aged and older women. Thus, long-term regular participation in Chinese fitness dancing can be used as a preventive measure to increase muscle strength in the lower limbs and reduce the risk of falls in middle-aged and older women.
