High Intensity Interval Training Versus Moderate Intensity Continuous Training in Frail Elderly

The assessment and systematic integration of physical activity into the care pathway of frail elderly people is essential to prevent loss of independence and improve the quality of life of this population. This project, which is part of routine care, aims to evaluate the practices and, in particular, the effects of different types of physical exercise currently in use at the Health and Sport Center of the Grenoble Alpes University Hospital. It therefore aims to optimize professional practices without changing the standard care provided to patients. Recommendations regarding intensity during cardiorespiratory endurance training sessions (moderate to high, taking into account emotional factors) are broad and vary greatly in their application depending on the facilities that work with older adults. This project aims to compare the exercise methods used on ergocycle at Health and Sport Center of Grenoble Alpes University Hospital: high-intensity interval training (HIIT) vs. moderate-intensity continuous training (MICT) to reverse the functional decline that occurs in frail older adults.
