[Hormone reactions to physical exercise following altitude training (author's transl)]

A three weeks physical training program at medium altitude induces some fonctional metabolic and hormonal changes in the response to physical effort. These changes vary, depending on whether the effort occurs on the 3rd or 7th day following return to sea-level. In the former case one observes a decrease in the somatotrophic response whereas in the latter one observes a decrease both in the somatotrophic and glucocorticoide response as well as in the level of blood contained lactic acids. These changes could be related to an improvement in the aerobic metabolism.
