Effects of wobble board training on weight distribution on the lower extremities of sedentary subjects

Abstract

Inequality of weight distribution on the lower extremities affects the posture and gait performance of an individual. The effect of wobble board training on weight distribution on the lower extremities is presently unknown. The purpose of this study was to investigate the effects of a six week wobble board exercise training program on the weight distribution in the lower extremities. Subjects (n = 16) in the wobble board group were trained three times a week for the period of six weeks. The subjects in the control group (n = 13) did not receive any training. Weight distribution symmetry scores improved by 9% and 2% in the wobble board and control groups, respectively, no significant difference was found between the two groups' pre-training weight distribution on the lower extremities. The two-ways repeated analysis of variance revealed a significant F ratio between the two groups (P < 0.001). LSD post hoc analysis showed significant improvements in the symmetry of the weight distribution at the 4th and 6th week of training compared to pre-training value within the wobble board group, while no significant improvement was recorded within the control group. Our findings implied that the wobble board exercise program could be used to improve the symmetry of weight distribution on the lower extremities in sedentary subjects.
