Abstract des Autors

This study was performed on 13 professional race-cyclists to examine changes in sex hormone binding globulin (SHBG), high density lipoprotein cholesterol (HDL-C) and serum lipid concentrations after training and after competition. While SHBG, total cholesterol and phospholipids increased and free fatty acids (FFA) decreased significantly during training, HDL-C and FFA increased and SHBG and triglycerides (TG) decreased significantly during the competition period. These latter changes in serum lipids and lipoproteins were assumed to be a direct effect of utilisation of muscle and plasma TG as fuels for exertion occurring only in extreme exercise. Changes in SHBG concentrations indicated that they were dependent on the conditions of the physical effort and could be related not only to the concentrations of androgens but also to the reduction in body mass.
