A eficácia dos programas de ganho de força muscular nos membros inferiores, na melhora da marcha em idosos comunitários

Abstract

Population aging is now a global phenomenon that not only affects developed countries, as well as the third world countries. The aging characteristics physiological changes lead to changes in movement patterns. Currently, the driving speed has been studied as a marker of health in the elderly.Objective: To evaluate the effectiveness of muscle-building programs of the lower limbs, gait of elderly. Methods: Literature review of studies on the influence of muscle strengthening of the lower limbs in the march of elderly surveyed in Medline, SciELO, PubMed, Capes, Peter, Lilacs. Studies were included with individuals older than or equal to 60 years, submitted to the muscle strength of the lower limbs. Results: Of 210 publications found, 18 met the criteria for inclusion, without restriction for publication period. The studies presented methodological heterogeneity. Most authors based the muscle strength of the lower limbs leads to improved gait. Conclusion: High-intensity muscle strengthening programs provide significant gains in muscle strength and therefore in functional mobility. However, low intensity exercises are able to improve functional performance in elderly despite small gains in muscle strength. A strict monitoring of professionals in physical therapy is necessary, at all stages of training in order to prevent any injuries and optimize results.
