Sixty meters speed running test was applied to the subjects only once in a dust running track. For hormone measurements, fasting blood samples were obtained form the subjects both before and after the race, and centrifuged during 30 minutes. Hormone level in the serum was measured using electrochemiluminecance method.Before the race, the serum levels of total testosterone, growth hormone, cortisone and insulin were 7,13±2,13 ng/mL, 1,92±2,64 ng/ml, 15,67±4,66 mg/dL and 5,51±2,94 ìIU/mL, respectively. The hematocrit was 46,13±2,11 insert ignore into journalissuearticles values(%);. After the race, the serum levels of total testosterone, growth hormone, cortisone and insulin were 7,53±2,17 ng/mL, 2,50±3,45 ng/mL, 15,06±4,46 mg/dL and 4,41±2,57 ìIU/mL, and hematocrit was 48,62±2,22 insert ignore into journalissuearticles values(%);. In conclusion, sixtymeter speed running as applied once with maximal loading causes a significant increase in the serum total testosterone level insert ignore into journalissuearticles values(p<0.01); and decrease in serum insulin level insert ignore into journalissuearticles values(p<0,001); after the race. Although the level of growth hormone increased after the race, this increase was not statistically significant insert ignore into journalissuearticles values(p>0,05);. Serum cortisone levels measured before and after the race were not significantly different insert ignore into journalissuearticles values(p>0,05);. There was a significiant increase in the mean hematocrit level after the race insert ignore into journalissuearticles values(p<0,001);. Short distance speed race caused sudden change in the serum level of some hormones. As a result of the physical activity, water loss occurs in the body, which in turn may lead to a decrease in the plasma volume. It was concluded that serum testosterone and insulin levels change in a sudden and substantial manner while cortisone and growth hormone levels do not change after sixty-meter speed race applied once with maximal load. Key Words: Speed race, total testosterone, growth hormone, cortisone, insulin Atabesbd 2009; 11 insert ignore into journalissuearticles values(2); : 35-45
