[Adaptation of blood sugar regulation during muscular activity. Effects of training].

Our aim was to study the adaptation of energetic metabolism to muscular activity and the effects of training upon these adaptations. So we realized swimming and running tests on young healthy adults, selected in "trained" and "untrained". The effects of muscular activity were reflected by a raise of serum F.F.A., clearly noted in "untrained" subjects ; the levels of glucose and growth hormone both raised, but especially in "trained" subjects. Cortisol level raised in varying degrees while insulinemia presented little changes.
