Effect of Resistance Training on Strength, Postural Control, and Gait Velocity among Older Adults

The purpose of this study was to examine the effects of a 14-week resistance training program on the anile strength training intensity, postural control, and gait velocity of older adults. Forty-two older adults (mean age = 72), 21 in the resistance and control groups, completed the 14-week project. The resistance training group participated in 14 weeks of resistance training three times per week using elastic bands (Theraband) for resistance. Isokinetic ankle strength, training intensity, postural stability, and gait velocity were measured prior to and following the 14-week intervention. Following the training, the resistance group exhibited improved ankle dorsiflexion, training resistances, and gait velocity, but showed no change in plantar flexion or postural control. The control group also exhibited improvements in dorsiflexion, but these gains were approximately one-half of the gains observed in the resistance training group. Finally, when adjusted for baseline differences, subjects in the resistance training group demonstrated no changes in the dependent measures over the control group.
