[Influence of coffee and amphetamine on the concentration of free fatty acids, triglycerides and glucose during exertion and in the restitution phase].

It was studied the effect of coffee and psychedrine on the behaviour of concentrations of free fatty acids, triglycerides and glucose in the blood serum during physical exercise with increasing load performed on bicycle ergometer. 20 healthy men received 200 ml of infusion from 20 g of natural coffee, whereas another 20 men received psychedrine 0.1 mg per kg of body weight. Their results were compared with those of the control group which performed only physical exercise. It was found that during physical exercise the concentration of FFA and triglycerides decreased and glucose concentration increased. These changes are significantly higher than in the control group (p less than 0.02). During the four-hour restitution increased glucose concentration and decreased triglyceride concentration were still persisting. However, during restitution it was not found the increase of FFA concentration which was observed in the control group.
