| Research Abstract |
The purpose of this research was to evaluate to dehydroepiandrosterone (DHEA) derive from the adrenal-cortex origin as an index reflecting the anabolic hormone response to exercise in female.
I : This study examined changes among young females of resting serum dehydroepiandrosterone sulfate (DHEAS) concentration after an eight-week period of resistance training. In the training group, resting concentration of serum DHEAS significantly increased after training (P<0.05). Percent change of DHEAS in the training group was greater than that of the control group (P<0.05). In the training group, the change of DHEAS level was positively correlated with the change of lean body mass during the training (r=0.61 ; P<0.05). The dramatic increase of resting serum DHEAS concentration after training indicates that DHEAS might be an anabolic hormone marker of adaptation to resistance training among young females.
II : The aim of this investigation was to evaluate salivary DHEA responses during a competitive period among female football players. The levels of salivary DHEA significantly increased during competition (2nd days) compared with Pre (p<0.05), and significantly decreased after competition compared with Pre (p<0.05). The levels of salivary cortisol significantly increased during the competition (2nd and 3rd days) compared with Pre (p<0.05). These data suggest that DHEA could be a useful endocrinological indicator for evaluating training status in female athletes.
Our data suggest that DHEA could be a useful endocrinological indicator for evaluating anabolic status to exercise in female athletes.
