Purpose Aging is associated with a progressive decline in overall muscle strength. Loss of lower limb strength leads to an increased risk of falls and a sedentary lifestyle. The purpose of this study was to investigate whether lower limb strengthening exercise leads to improved lower limb strength and balance function for the elderly. Subjects From a total of 74 respondents, 50 subjects were randomly assigned to either a training group (n = 30) or a control group (n = 20). The subjects ranged in age from 65 to 82 years. A randomized controlled trial compared the effects of strengthening exercise and balance function. Methods Leg extension and lower curl exercises were performed during the 12-week study. Results After training, the lower limb strength and balance of the individuals in the training group had significantly improved compared to the baseline. Conclusion Improvement in lower limb strength may lead to balance enhancement in neurologically intact older persons.
