The purpose of this study was to examine the effect of a practical resistance training program for the lower extremities on mobility in independent, community-dwelling older adults. Twenty-two volunteers with a mean age of 72.9 years underwent two identical pretests 1 month apart. Lower extremity strength, locomotor stability, preferred gait velocity, and step lime in obstacle clearance were assessed. Participants then engaged in an 8-week resistance training program for the lower extremities using adjustable ankle weights. Following a posttest, a repeated-measures ANOVA was used to determine whether changes in strength and mobility when the treatment was interjected differed from when it was not. Results indicated that the training had a limited effect on strength and no effect on mobility. The feasibility of practical resistance training interventions to counteract muscle weakness and associated immobility in independent older adults is discussed.
