Brief summary
This is a pilot study for evaluating the feasibility of using High Intensity Interval Training in geriatric hospitalized patients compared to the standard current rehabilitation practice.
Detailed description
High Intensity Interval Training (HIIT) has shown a superior effectiveness and efficiency when compared to Moderate Intensity Continuous Training (MICT) in several types of patients and in healthy subjects. There are no data on HIIT in a general geriatric population. This study is a pilot study evaluating the feasibility of using HIIT in geriatric hospitalized patients compared to the standard current rehabilitation practice without HIIT. It is our desire to perform a larger randomized comparative trial between HIIT and MICT if the pilot study proves its feasibility.
Interventions
HIIT 4 times a week, 30 minutes duration
Traditionnal group rehabilitation, 3 times a week, 1 hour duration
