This study explores the relationship between nutritional supplements commonly used by athletes and obesity. The research employs a cross-sectional design, recruiting a convenience sample of athletes aged 20-40 years from local sports clubs and fitness centers. Participants completed a questionnaire regarding demographic information, athletic background, training regimen, and dietary habits. Anthropometric measurements, including height, weight, body mass index (BMI), and body composition, were obtained using standardized procedures. The study assesses the prevalence and patterns of nutritional supplement use among athletes, including protein powders, creatine, branched-chain amino acids (BCAAs), and weight management supplements. Additionally, obesity status is determined based on BMI classifications. Statistical analysis includes descriptive statistics, chi-square tests, and logistic regression analysis to examine the association between supplement use and obesity risk while controlling for potential confounding variables. The study aims to contribute to a better understanding of the impact of nutritional supplements on obesity risk among athletes and inform evidence-based practices in sports nutrition.
