High-intensity interval training versus moderate continuous cycling for frail older adults

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is an observational, routine-care project conducted at the Health and Sport Center of Grenoble Alpes University Hospital comparing two real-world exercise approaches on an ergocycle: high-intensity interval training (HIIT) versus moderate-intensity continuous training. Participants are adults aged 70+ meeting at least one Fried frailty criterion who are medically stable and able to use a stationary bike safely. The protocol does not change standard care but records current practices, cardiorespiratory responses, functional mobility, and motivation for physical activity. Results aim to inform how exercise intensity is applied in care pathways for frail older adults.
