About this study
The aim of this study was to investigate the effects of banned substances on some metabolic functions in male athletes in order to raise awareness among individuals who use these substances by highlighting the potential harms of using banned substances to draw attention to the issue and raise awareness. 2) Methods: The study is a randomised cross-sectional study. The study included 20 male amateur athletes who had actively practised bodybuilding, arm wrestling, powerlifting and weightlifting in the last 5 years and had not participated in competitions. The study group consisted of 10 adult male amateur athletes who had used banned substances at least once a year in the past 5 years, while 10 male amateur athletes who had not used banned substances with similar qualifications formed the control group. Participants were included in the study on a voluntary basis. Participants' age, sports age, height, weight and BMI variables were selected and parameters related to liver, kidney, hormone and lipid profiles were determined. The Shapiro-Wilk test was used to test the normality of the values obtained from the data. The independent t-test was used for the data showing a normal distribution and the Mann Whitney U- test was used for the data not showing a normal distribution.
