Real-time Videoconference-based Exercise in Eldercare Workers

12-week exercise program consisting of two weekly 45 minute group-based sessions, remotely supervised by a professional via real-time videoconference. Each session will consist of a warm-up (5-10 min), general strengthening (30 min) and cool-down (5-10 min). Warm-up will include general joint mobility and exercises focused on increasing heart rate. General strengthening will include 4 series of 6 exercises (2 for lower limb, 2 for upper limb and 2 for the trunk) performed with minimal equipment, combining body-weight and elastic-band exercises. Three difficulty levels will be set for each of the exercises, and progression will be made at weeks 5 and 9. Participants will be asked to work in a given rate of perceived exertion (between 3 and 5 in Borg's CR10 scale) and not to reach failure in any of the exercises. Cool-down will include stretching and breathing/relaxing exercises.
