The Combined Effect of Glutamine and Creatine Supplementation on Body Hydration Level and Some Performance Parameters in Football Players

Abstract

The aim of this study was to investigate the combined effect of glutamine (GLU) and creatine (CRE) supplementation on body composition, body hydration levels, and selected performance parameters in football players. Eight volunteer licensed male football players aged 19 to 23 participated in this study. The study was randomized and single-blinded. In the study, athletes were administered 10 g of glutamine and creatine before and after training for seven days. Some tests, measurements, and analyses were performed in equal physical conditions with seven-day intervals using a pre-test/post-test experimental design. The research data were analyzed with a dependent sample t-test. In the comparison of the parameters pre- and post-supplementation, statistically significant differences were found in body mass, skeletal muscle mass, total body water, body mass index (BMI), metabolic rate, protein, and mineral values (p
