Abstract
PURPOSE:The purpose of this study was to investigate the relationships between physiological and psychological variables by comparing the stress hormones (DHEA-S and cortisol) levels and anxiety responses prior to basketball competitions. METHODS: Twenty one male professional basketball athletes (age 19.8 ± 0.3 years) were recruited in this present study. All the subjects completed the questionnaire CSAI-2. Blood samples were collected on two separated day: before training (training state) and prior to basketball game (pre-competitive states). Dehydroepiandrosterone sulfate (DHEA-S) and cortisol levels were measured in the blood for all subjects. RESULTS:Self-confidence was significantly lower in competitive state compared to training state, whereas cognitive and somatic anxieties were not significant altered. No significant difference in DHEA-S and cortisol levels between competitive state and training state. Negative correlation between DHEA-S concentration under competitive state and change in cognitive anxiety was observed. Cortisol concentration under competitive states had negative relationship with change in somatic anxiety. CONCLUSIONS:According to above evidence, we suggested that blood stress hormone can provide a prediction to anxiety in pre-competition condition.
