Abstract
Plasma testosterone (T) levels, sex-hormone-binding globulin (SHGB) capacitiesand T/SHGB ratios were measured in fifteen athletes during and after shortand long-term running exercises. Plasma SHGB did not change either during or after the running tests. In contrast, exercises of high intensity resulted in a slightly higher T/SHGB ratio during the exercise and a significantly lower T/SHGB ratio a few hours after the exercise. No difference in mean plasma SHGBcapacity was found between trained and untrained men. This study indicates that increases or decreases in total plasma testosterone levels in exercise are associated with parallel changes in the free testosterone fraction. Verf.-Referat
