Exercise and functional tasks among adults who are functionally limited.

This study compared the efficacy of 16 weeks of either resistance training, aerobic walking, or combined resistance training and aerobic walking on the performance of functional tasks among adults age 65 years and older with limited functional ability. One hundred thirty-one older adult individuals were randomized into four groups: resistance training, aerobic walking, combined resistance and aerobic walking groups, or a nonexercise control group. Each of the exercise groups documented 70% compliance with their respective exercise intervention, which included three weekly exercise sessions. At baseline, and 8 and 16 weeks following baseline, all participants completed six assessments of their functional ability. Analysis of covariance indicated that all three exercise intervention groups significantly improved measures of functional ability, with the resistance group demonstrating the most consistent gains over the six measures. These findings indicate that older adults who are functionally limited can improve their functional ability through a variety of types of exercise.
