Abstract :

Objective: It has been aimed to evaluate the response of metabolic factors in elite female and male athletes to increasing maximal aerobic exercise and to evaluate pre-exercise and post-exercise serum levels. Material and Method: 27 young (average age: 19) professional field hockey players (13 female, 14 male) were included in this study. Shutle Run test has been applied to the subjects. The subjects have run the distance between two lines, which was 20 meters, with accelerating (8 km/s) speed. In the running tests, which were performed with signal tone, the test was finished when the subject has missed two signals. The blood samples, which were taken before the exercise, right after the exercise and after 1 hour from the exercise, were kept in 80�C until analysis. In the analysis, serum levels have been measured by using Growth Hormone (GH), Insulin-like Growth Factor-1 (IGF-1), Protein Bound Insulin-like Growth Factor (IGFbp), Gamma glutamyltransferase (GGT) and insulin (INS) original kits. The data have been statistically evaluated separately for male and female athletes. Findings: Immediately after the exercise, GH, IGF-1, IGFbp, GGT and INS serum levels have increased. While this increase was substantial in GH and INS, it was smaller in IGF-1, IGFbp and GGT. After 1 hour from the exercise, GH, INS, IGF-1, IGFbp and GGT serum levels have decreased. GGT\'s response to increasing maximal aerobic exercise is higher in females comp� to males. IGFbp responses are not statistically meaningful in both genders (p<0.05). Result: GH, IGF-1, IGFbp, GGT and INS\'s response to increasing maximal aerobic exercise in elite athletes and post-exercise serum levels are found to be beneficial in terms of health and body position.
