Changes in cortisol and testosterone concentrations were recorded in male (n=5) and female (n=5) elite rowers during an indoor rowing competition at a 2 km distance. In men, who were to win 3 times as high prizes as women, the mean cortisol level increased by 46% from rest to 15 min pre-competition, compared with 27% in women. The post-competition values significantly increased and were higher in men than in women (304+/-34 and 212+/-13 nmol/l, respectively), the levels of glucose and lactate being about the same in both groups. Another group of female rowers (n=5) performed a graded laboratory exercise and an 8 km race, qualifying for the foursome representation team. Both pre- and post-race cortisol levels were significantly higher than in case of laboratory exercise. The data indicate an association between the motivation for maximal exertion and the psychohormonal mobilisation. Verf.-Referat
