Design and Validation of FEXO: A Playful Exercise Program for Institutionalized Frail Older Adults

A 14-week supervised multicomponent playful exercise program for institutionalized older adults. It consists of 3 sessions per week (55-60 minutes), including aerobic, strength, balance, flexibility, and gait exercises in a group-based, game-like setting. The structure includes 2 weeks of familiarization followed by 3 progressive 4-week levels. The intervention aims to improve intrinsic capacity, reduce frailty, and enhance physical and cognitive function.
