Aquacycling Clinical Trial
Official title:
Evaluation of Energy Balance During Aquatic Cycling Exercise in Premenopausal Women: Effect of Body Composition Status
Exercise training on an immersible ergocycle is becoming more popular as it appears to be more suitable for men and women even with poor physical activity level. Commercial tagline highlight beneficial effect of this activity on weight management. However there are poor information concerning the energy response induced by this activity. The aim of this project is to investigate energetic response (energy expenditure and food intake) of a single bout of cycling exercise in water vs on dryland in normal weight and overweight premenopausal women.
After inclusion visit, all subject will be submitted to DXA to obtain body composition data.
Then subjects will be submitted to four experimental session in a semi-randomized order. For
all those session, subjects will take a standardized breakfast (570kcal) three hours before
experimental session.
Control session (CON): subject will stand sited without any activity during 30 min.
Water exercise session (WAT): subject will exercise on an immersed ergocycle during 30 min
at 50 rpm.
Dryland session 1 (LAND-1): subject will exercise on dryland, on the same ergocycle than in
WAT session, during 30 min at 50 rpm.
Dryland session 2 (LAND-2): subject will exercise on dryland on the same ergocycle than in
WAT. Intensity of exercise will be set at the same heart rate average than in WAT session,
exercise will be stopped when subject will have reached the same energy expenditure than
during WAT session.
During each session, energy expenditure, heart rate and rate of perceived exertion will be
measured at 15 min and 30min.
Appetite and hunger sensation will be measured with a specific scale at different time point
of each day of experimental session. Thirty minutes after the end of each experimental
session subjects will have a buffet meal for lunch time.
