Testing the Dose-response of Coordination Training for Older Adults.

The intervention will consist of 8 weeks of exercises to decrease the variability of participants' body and gait coordination. The intervention will consist of 1 training session /week in the Mobility Research Laboratory and 4 days of home-based training. In each session participants will perform 6 trials of 4 body coordination exercises and 1 gait exercise. In the intervention sessions participants will perform interlimb coordination exercises, synchronizing body segments with auditory metronome tones. Participants also will perform a gait exercise by synchronizing steps with an auditory metronome during walking. The metronome will assist participants to retrain their movement timing to decrease coordination variability.
