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 stance time in elderly women.
30 elderly women (66.1 5 5.7) with no history of falls voluntarily participated in this study. They were divided into 3 equal groups according to age and pre-test balance. 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 stance 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).
The results of this study showed that 6 weeks of isometric and concentric resistance training had a significant effect on improving gait speed (P: 0.001) and decreasing the double stance time (P: 0.001) in older women compared to the control group. As the effect of isometric training on the double stance time is more than concentric training. In contrast, the effect of concentric resistance training on walking speed was longer than training.
Isometric resistance training also reduces the double stance time, and concentric training improves walking speed. As a result, this type of exercise can effectively improve walking parameters in the elderly.
