ABSTRACT=The study aimed to explore the associations between water intake and body composition and differences of body composition in different water itake and hydration statuses among young male athletes. A cross-sectional study was conducted among 111 young male athletes in Beijing, China. Total drinking fluids (TDF) and water from food were assessed using a 7-day, 24-hour fluid intake record questionnaire and the duplicate portion method, respectively. The osmolality of 24hour urine and blood samples was tested. Body composition was measured using a bioelectrical impedance analyzer twice at 5-minute intervals. Participants were divided into two groups based on the recommendations of total water intake (TWI) and TDF in China, as well as into three groups based on 24-hour urine osmolality.Pearson's correlation coefficients were calculated to determine the relationship between water intake and body composition. Chi-square tests and Student's t-tests were used to compare differences. A total of 109 participants completed the study.
