ABSTRACT
In this study, our objective was to assess the influence of sixty-meter speed running as
applied once with maximal load on sudden changes in the levels of total testosterone, growth
hormone, cortisone and insulin.Twenty-two healthy male students aged from 18 to 23 years who were
attending to High school of Physical Education and Sports were included in the study. 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 (%). 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 (%). In conclusion, sixtymeter
speed running as applied once with maximal loading causes a significant increase in the serum
total testosterone level (p<0.01) and decrease in serum insulin level (p<0,001) after the race. Although
the level of growth hormone increased after the race, this increase was not statistically significant
(p>0,05). Serum cortisone levels measured before and after the race were not significantly different
(p>0,05). There was a significiant increase in the mean hematocrit level after the race (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
