Telerehabilitation on Physical Fitness, Functional Status, and Quality of Life in Frail Older Adults

Each session will consist of a warm-up activity (5-10 min), main exercise activity (30-40 min), and cool-down activity (5-10 min) following the guidelines of multicomponent exercise program Vivifrail. Exercise intensity will be controlled based on the Rating of Perceived Exertion (RPE) on the Borg scale and heart rate measured with a smartwatch before, during, and after each exercise session according to the guidelines of the American College of Sports Medicine (ACSM), as explained below. The warm-up and cool-down activities will include stretching and walking in place (9≤RPE≤10 and 40\<55% maximum Heart rate (HRmax). While the main exercise activity will consist of strength, resistance exercise, cardiovascular exercises, and balance exercises (to avoid falls) performed using dumbbells, colour-coded resistance bands (Thera-Band; Hygenic Corp.) and a chair (11\<RPE≤15 and 55\<70 HRmax).
