Soccer players' agility can be affected by many factors, including nutrition and body composition. The primary objective of our study is to reveal the relationship between nutritional attitudes and anthropometric measurements and agility in elite adolescent soccer players. Our secondary objective is to determine the effect of daily fluid intake and daily sleep duration on anthropometric measurements, nutrition attitude scores, and agility in soccer players. Study was conducted on 51 male soccer players aged 14-18. Information on the soccer players' sociodemographic characteristics and lifestyles was obtained via a questionnaire. Body composition analysis was measured using a Bioelectrical Impedance Analysis (BIA) device, and hand grip strength was measured using a hand grip dynamometer. Height, waist circumference, and hip circumference were measured. Soccer players' attitudes toward nutrition were assessed using the Nutrition Attitude Scale (NAS), and their agility was assessed using the Agility T-Test.
