Effect of exercise on balance, strength and reaction time in older people

Abstract

Twenty subjects enrolled to take part in an exercise programme (mean age = 62.5 years) and 20 control subjects (mean age = 65.5 years) underwent assessments of strength, reaction time, neuro-muscular control and body sway. The exercisers participated in one hour exercise sessions comprising a cardiorespiratory (walking) component and a gentle exercise component twice weekly for 20 weeks. All subjects were then re-tested for the same measures after the completion of the programme. The exercisers showed improved quadriceps strength, reaction time and reduced body sway when compared with the control group; the exercise group showing continued improvement throughout the programme in tests of body sway. The findings suggest that exercise can improve physical function in older people. © 1994, Australian Physiotherapy Association. All rights reserved.
