The purpose of this study was to evaluate whether a 12-wk functional circuit-training program (FCT) could alter markers of physical frailty in a group of frail community-dwelling adults. Fifty-one individuals (31 women, 20 men), mean age (+/- SD) 84 (+/- 2.9) yr, met frailty criteria and were randomly assigned into groups (FCT = 26, control group (CG) = 25). FCT underwent a 12-wk exercise program. CG met once a week for health education meetings. Measures of physical frailty, function, strength, balance, and gait speed were assessed at weeks 0, 12, and 36. Physical-frailty measures in FCT showed significant (p < 0.05) improvements relative to those in CG (Barthel Index at weeks 0 and 36: 73.41 (+/- 2.35) and 77.0 (+/- 2.38) for the FCT and 70.79 (+/- 2.53) and 66.73 (+/- 2.73) for the CG. These data indicate that an FCT program is effective in improving measures of function and reducing physical frailty among frail older adults.
