- University of Avignon
- Brief Summary
The main objective is to measure the effects of intense brief exercise program in the workplace of administrative staff on the cardio-metabolic health
- Detailed Description
Backgrounds: Very short (\< 1 minute) and intense exercises, entitled "exercise-snacks", have been reported to be effective 1) in improving physical fitness over 6 weeks and 2) in improving vascular function and lowering blood glucose levels over one day. These studies were all carried out in the laboratory. The question therefore arises as to whether these acute vascular and metabolic benefits, as well as those on physical fitness, are sustainable over time following a chronic "exercise-snacks" program applicable in the professional environment to sedentary, overweight people.
Aims of this project is therefore to measure the effects of an "exercise-snacks" type physical activity program in the workplace of administrative staff on the cardio-metabolic health and sedentary behaviour of staff.

Group Intervention Description Exercise-snacks group Exercise-snacks program They will perform a "exercise-snacks" program and receive information about physical activity
- Primary Outcome Measures
