PURPOSE: This study compared cognitive task-directed functional motor control ability for reaching and kicking movements in younger and older adults. METHODS: Subjects were divided into two groups of younger and older adults, with 13 subjects in each group. Subjects were required to perform a dual task combining a functional movement and cognitive component. The task consisted of reaching and kicking movements. Participants performed indicated movements when a target appeared on a monitor. The target randomly appeared on the monitor every 10 seconds. The total performance time (TPT), joint angular velocity (JAV), and muscle activation time were used to evaluate motor control ability. RESULTS: There were significant differences in all evaluation factors in a comparison of younger and older adults (p<.05). TPT was significantly shorter in older adults, and JAV and muscle activation time were significantly slower than that in the younger adult group. Although the results for older adults were within the normal range for functional assessment, their motor control abilities were significantly worse for cognitive tasks compared with those of younger adults. CONCLUSION: The results of this study indicated that a motor control assessment tool using a cognitive task would be helpful in assessment of motor control ability in healthy older adults.

We developed research strategies for measuring functional performance and proprioception. We determined whether resistance training improves functional performance in the older adult, whether resistance training improves proprioceptive sense, and whether improvement in functional performance and/or proprioception are a direct result of the resistance training or a result of movement independent of strength gains. The answer to these questions will enable those in the sport fitness industry and medical practioners to better advise the growing number of older adults about the benefits of specific types of exercise. The will also enable the medical practitioner to prescribe appropriate exercise to those with limitations in functional ability in attempts to restore independent living.
