RESUMEN
Glutamine plays a key role in cell protection following stress, by causing a simultaneous increase in hsp72 expression, which is dependent on glutamine metabolism and its relation with cortisol levels and gluconeogenesis. To assess the effect of glutamine supplement ingestion on hsp72, cortisol and glucose plasma changes after exercise, 28 soccer players were divided in four groups; the control, supplement, supplement-exercise and the exercise groups.0.5 g/kgBw supplement and placebo consumed 5 ml/kgBw volume of water one hour prior to the exercise protocol, which included 3 stages of 20 minutes running [80% HRmax intensity] with 5 minute rest periods between each stage. Baseline, and pre, post and 90 minutes after exercise, blood sampling was done and cortisol, glucose and hsp72 levels were measured using RIA, Enzymatic, and Elisa tests respectively. Data was analyzed with MANOVA and Bonferoni post hoc tests, P
