Abstract
Introduction: Elderly age is associated with a decrease in physiological and functional capacity that can lead to increased disability and decreased balance during walking, decreased speed and deformity of walking. The purpose of this study was to compare the effect of isometric and concentric resistance training on walking speed and double support time in elderly women.
Methodology: The present study was a quasi-experimental study with pre-post test design with control group.30 elderly women (66.1±5 5.7) with no history of falls voluntarily participated in this study. They were divided into 3 hhomogenous groups according to age and pre-test balance score. All kinematic information related to the pre-test and post-test was obtained using the motion analyzer and at the preferred speed during the walking. After the pre-test phase, the training program was performed in 18 sessions, which consisted of three sessions per week, and walking speed and double support time were measured by a motion analyzer.Data were analyzed by Mixed factor analysis of variance (2 ×3 ×3) and LSD as a post hoc test (P≤0.05).
Findings: The results of this study showed that 6 weeks of isometric and concentric resistance training had a significant effect on improving walking speed (P= 0.001) and decreasing the double support time (P= 0.001) in older women compared to the control group. As the effect of isometric training on the double support time is more than concentric training. In contrast, the effect of concentric resistance training on walking speed was more than isometric training.
Discussion: In general, resistance training had a positive effect on functional capacity of elderly people. As a result, this type of exercise can effectively improve walking parameters in the elderly.
