Effects of resistance- and flexibility-exercise interventions on balance and related measures in older adults

J Aging Phys Act. 2009 Oct;17(4):444-54. doi: 10.1123/japa.17.4.444.

Abstract

This research explored the balance benefits to untrained older adults of participating in community-based resistance and flexibility programs. In a blinded randomized crossover trial, 32 older adults (M = 66.9 yr) participated in a resistance-exercise program and a flexibility-exercise program for 16 weeks each. Sway velocity and mediolateral sway range were recorded. Timed up-and-go, 10 times sit-to-stand, and step test were also assessed, and lower limb strength was measured. Significant improvements in sway velocity, as well as timed up-and-go, 10 times sit-to-stand, and step test, were seen with both interventions, with no significant differences between the 2 groups. Resistance training resulted in significant increases in strength that were not evident in the flexibility intervention. Balance performance was significantly improved after both resistance training and standing flexibility training; however, further investigation is required to determine the mechanisms responsible for the improvement.
