Beta2-adrenergic stimulation increases energy expenditure at rest, but not during submaximal exercise in active overweight men

Purpose β2-Agonists have been proposed as weight-loss treatment, because they elevate energy expenditure. However, it is unknown what effect β2-agonists have on energy expenditure in overweight individuals. Furthermore, the influence of β2-agonist R- and S-enantiomer ratio for the increased energy expenditure is insufficiently explored.
