Performing high-intensity physical exercise constitutes an important stressor which produces important alterations in hormonal metabolism. The aim of this study was to assess the acute effect of a competitive handball match on the urinary excretion of steroid hormones in young female players. To that end, the urinary profiles of the free and glucuroconjugated steroid hormone fractions in a group of 19 players (18.47 ± 2.26 years old), belonging to several teams in the Regional Junior-Senior Extremaduran League, were determined both before and after the same match. In order to determine and quantify the steroids, a gas chromatography-mass spectrometry technique (GC/MS) was used. On the one hand, the results obtained after the match showed a significant increase in cortisone, tetrahydrocortisol and total glucocorticoids concentrations. On the other hand, when the ratio of the total amount of anabolic hormones to the total amount of catabolic hormones was analysed, an important decrease was also observed. We can therefore conclude that both acute physical exertion and physcological and emotional stress induced by the competitive handball match, were objectively reflected in an immediate alteration of the urinary steroid profile, a decrease in their anabolic state and an increase in their catabolic state.
