ABSTRACT
Falls among older adults are a growing public health problem. Previous research
suggests that the regular practice of physical activity in older adults improves balance and
reduces falls. The objective of this study was to determine whether balance-specific training,
in addition to regular physical activity, could improve balance in older adults, and whether
there would be a dose-response to frequency of balance training.
A six-week balance-training program was conducted with 60 older adults (60-87
years) who were already participating in a regular program of physical activity. All
participants continued with their regular exercise program while adding balance training in
one of three doses: three 20-minute balance-training sessions/week (3-Day); one 20-minute
balance-training session/week (1-Day); and no additional balance training (Control).
Participants were tested pre-and post-training and a repeated measures ANOVA
revealed significant intervention effects of training for 1) single-leg-stance on the left
(p=.019) and right (p=.026), 2) limits-of-stability 95% area ellipse (p=.036) and
anteroposterior maximum excursion (p=.01), 3) foam eyes closed/foam eyes open
mediolateral difference score (p=.008), and 4) a trend toward significance for alternate
stepping (p=.053). Both 3-Day and 1-Day groups saw more improvement than controls, with
the 3-Day group achieving the greatest improvements overall. The results of this study
suggest that physically active older adults who exercise regularly can benefit from the
addition of balance training to their current exercise program. Three 20-minute sessions per
week led to the greatest improvement; however it appears that even one 20-minute session of
balance training per week may lead to improvement of balance.
