Abstract
Aging has a direct impact on balance due to changes in sensory and motor response, sarcopenia, reduced muscle strength and range of motion that occur in the elderly. In this context, strength training (ST) programs are seen as a valuable strategy to minimize the deleterious effect of aging on strength production and balance in this population. The purpose of the study was to evaluate the effect of 12 weeks of progressive intensity ST on static balance variables in the elderly. The study included 23 elderly with an average age of 65±8.61 years, of both sexes, who performed a twelve-week strength training program, with a frequency of three times a week and with progressive intensity (60 - 85% of 1-RM). Balance was assessed before and after the intervention period, through stabilometric assessment on a force plate. After the intervention, there was a reduction in the anteroposterior amplitude (p=0.01), in the anteroposterior velocity (p=0.01) and in the total displaced area (p=0.04). It is concluded that the strength training can be used as a key tool to minimize the deleterious effect of aging on the maintenance of static balance.
