INVESTIGATION OF PITUITARY DYSFUNCTION IN RETIRED PROFESSIONAL SOCCER PLAYERS

ABSTRACT Introduction: It is well-known that pituitary dysfunction can develop as a result of traumatic brain injuries. One reason for such injuries is collision during contact sports. Objectives: The aim of this study was to investigate the effects of heading the ball and concussion on pituitary function in retired soccer players. Methods: Thirty-two retired soccer players, with an average age of 43.38 ± 5.49 (35-59) and 26 sedentary individuals with an average age of 43.31±6.38 (35-59) were included in this study. The subjects were questioned about their soccer-playing background, history of head trauma and concussion, and cardiometabolic diseases. One day one, blood samples were taken to investigate the baseline hematologic and biochemical parameters. On day two, the ACTH stimulation test was conducted, and on day three, glucagon stimulation tests were carried out. Resting EKG, transthoracic ECHO and exercise stress tests (for MET values) were also conducted. For the statistical analysis, The Student's t-test was used to compare the results of the two groups. The level of significance adopted was p<0.05. Results: It was identified that 5 out of 32 soccer players (16%) had experienced concussion during their soccer careers. The growth hormone (GH) levels of 3 retired soccer players (9.2%) and 3 sedentary individuals (10%) was below 1 ng/dl, which was accepted as the threshold value. There were no significant differences between hematological, biochemical and cardiometabolic parameters of the soccer players with low GH levels and those with normal GH levels. There was no significant relationship between the number of headers performed and GH deficiency. Conclusion: Although low GH levels were detected in almost 10% of the retired soccer players, the frequency of hypopituitarism was not higher than in the sedentary control group. Level of evidence I; Prognostic Studies.
