[Effect of 3-month exercise training on daily energy expenditure in formerly obese women with reduced and stable weight].
Predisposition to obesity has been suggested to be related to a low energy expenditure (EE). This condition could be counteracted by physical exercise. In the present study we wanted to elucidate if aerob training could increase sedentary 24-hour energy expenditure in formerly obese subjects. Seven reduced-obese premenopausal women were studied in a respiration chamber before and after a three month period of aerobic training. No significant effects of training were seen on daytime, sleeping or total 24-hour EE. However, the change in daytime EE was positively correlated to the change in VO2max. Sleeping and 24-hour respiratory quotients were slightly increased after the training period. In order to reveal a possible role of the sympathetic nervous system in the observed effect of training, additional experiments were performed with beta blockade. However, no interactions between training and beta blockade were found.
