Brief Summary

The inexorable decline in motor skills during aging provides the investigators with an elderly population with various functional limitations. Among these, the ability to walk, being associated with the risk of falling has been studied by several authors. The adoption of strength and power training as an intervention strategy to reduce the negative effects arising from the physiological or pathological process of aging has been widely discussed in these studies. However, the effects of these interventions on biomechanical gait indicators have not been fully debated yet. Therefore, this study aimed to compare the effects of these two training protocols on functional capacities and biomechanical gait parameters of elderly women.
