This experiment was conducted to compare the effects of a 12-week Smovey-based exercise program and a conventional unloaded multi-component exercise program on functional fitness, handgrip strength, and task-related upper-extremity muscle activity in older women. In this trial, 46 community-dwelling women aged 65 years or older were allo-cated to a Smovey-based multicomponent exercise group (SMG) or a conventional unloaded multicomponent exercise group (CG). One CG participant withdrew (final n=45: SMG, 23; CG, 22). Both groups com-pleted supervised 60-min sessions three times weekly for 12 weeks with identical movement patterns, volume, and perceived-exer-tion-based progression; only the SMG held Smovey rings. Five senior fitness test items, dominant-hand grip strength, and surface electro-myographic activity of six upper-extremity muscles during a standard-ized fixed-load shoulder task, normalized to maximal voluntary contrac-tion (%MVC), were assessed before and after the intervention and ana-lyzed using 2×2 mixed-design analyses of variance. Significant time ef-fects were observed for all functional fitness outcomes and handgrip strength. Group-by-time interactions were significant for the 30-sec arm curl and handgrip strength, but not for the chair stand, 2-min step, back scratch, or 8-foot up-and-go. The %MVC increased in both groups for all six muscles, whereas interactions were significant only for the bi-ceps brachii, triceps brachii, flexor carpi radialis, and brachioradialis, not for the anterior or middle deltoid. Both programs improved function-al fitness. The Smovey-based program produced greater gains in arm-curl performance and handgrip strength, while differential changes in task-related muscle activity were confined to the elbow and forearm muscles rather than the shoulder muscles.
