Does exercise intensity and experience differ between online home-based exercise classes and face-to-face exercise classes? A randomised, crossover study.

Twenty-five, healthy, low-moderately active older adults, will be recruited to take part in a 4-week randomised, crossover study. Participants will participate in 4 sessions of exercise classes across the 4-weeks. These will consist of 2 online home-based exercise classes and 2 sessions of face-to-face exercise classes delivered live by a High Life Highland (HLH). Online classes will be provided using Zoom, which enables two-way interaction and communication. Exercise intensity will be monitored throughout the 4 sessions through the deployment of commercially available wearable devices (Polar heart rate monitor (Polar Verity Sense).
