Effects of timing on energy expenditure during rest and exercise in obese women.

The metabolic rate of obese women and control group was established by indirect calorimetry. Each subject in resting state and during ergometer cycling test was examined three times a day, before meals. The resting metabolic rate of both groups increased during the day. During exercise the energy expenditure of obese subjects was significantly higher than that of the control group. The presented results show that in obese subjects the highest exercise energy expenditure appeared in the evening and in the afternoon.
