Many obese individuals experience difficulties in executing household activities. In this study, we investigate the cardiorespiratory fitness (CRF) of obese vs. non-obese women, and the impact of obesity on cardiorespiratory functioning during daily household activities.
Methods: On 48 sedentary female subjects will be assessed by cardiorespiratory exercise testing with evaluation of peak oxygen uptake (⩒O2), heart rate (HR) and maximal cycling power output. Next, cardiorespiratory functioning will be assessed during household activities such as ironing (A1), cleaning floor (A2), walking and climbing stairs (A3).

The cardiopulmonary exercise testing is performed on a cycle ergometer connected to cardiovascular and respiratory software. Subjects have a facemask, which collected respiratory and metabolic variables.An incremental exercise test is performed up to exhaustion. ⩒O2 is recorded and heart rate is averaged by an electrocardiogram system. Cardiopulmonary exercise testing during household activities Subjects have to perform 3 everyday life household activities: ironing,cleaning floor,walking and climbing stairs.A wearable ambulatory indirect metabolic system is used with Holter mode to record cardiorespiratory measures.Subjects have to breathe through the K4b2 facemask and turbine.

Comparison of relative peak oxygen consumption between obese and non-obese women , mesured with indirect calorimetry
⩒O2 peak comparison between OB vs NO women. For each household activity, the intensity expressed by the ratio ⩒O2 activity/resting ⩒O2 or the ratio ⩒O2 activity /⩒O2 peak will be compared between NO and OB
