AIM: This study aimed at describing the impact of the five-day handball competitions on the total and free testosterone hormone levels in handball players.
METHODS: Twelve handball players having played handball for five years or more with averages of 22.16±1.85 years of age, 181.16 ±5.18 cm in height and 81.59±11.99 kg body weight took part in the study on voluntary basis. Measurements were made after the subjects were briefed about the tests. Blood samples were taken in the morning between 9:00 and 10:00 hours in a laboratory. The 5-mL blood samples of the subjects which were taken from the forearm antecubital area into yellow-capped gel tubes in line with the hygiene rules were analyzed in the central laboratory to check the testosterone hormone levels by using auto-analyzer. Student’s t test was made in dependant samples to define the difference between before and after the competition. The significance level was defined as 0.05.
RESULTS: It was found out that there were increases in testosterone levels of the handball players before and after competitions (P<0.05).
CONCLUSION: In conclusion, it is considered that the increase in testosterone hormone levels of the participating handball players was due to the acuteness of the loading during the five-day intensive competitions.
