Core Muscle Strengthening’s Improvement of Balance Performance in Community-Dwelling Older Adults: A Pilot Study
To determine the effect of core muscle strengthening on balance in community-dwelling older adults, 24 healthy men and women between 65 and 85 years old were randomized to either exercise (EX;n= 12) or control (CON;n= 12) groups. The exercise group performed a core strengthening home exercise program thrice weekly for 6 wk. Core muscle (curl-up test), functional reach (FR) and Star Excursion Balance Test (SEBT) were assessed at baseline and follow-up. There were no group differences at baseline. At follow-up, EX exhibited significantly greater improvements in curl-up (Cohen’sd= 4.4), FR (1.3), and SEBT (>1.9 for all directions) than CON. The change in curl-up was significantly correlated with the change in FR (r= .44,p= .03) and SEBT (r> .61,p≤ .002). These results suggest that core strengthening should be part of a comprehensive balance-training program for older adults.
