Abstract
The purpose was to assess the effect of oral glutamine supplementation combined with resistance training in young adults. Thirty-one subjects, aged 18- 24, were randomized (double blind) to receive glutamine (0.9g/kg lean tissue mass; n=17) or placebo (0.9g/kg lean tissue mass; n=14) during 6 weeks of total body resistance training. Exercises were performed for 4-5 sets of 6-12 repetitions at intensities ranging from 60-90% 1-RM. Before and after training, measures were taken for 1-repetition maximum squat and bench press strength, peak knee extension/ flexion torque (Biodex isokinetic dynamometer), lean tissue mass (dual energy X-ray absorptiometry) and muscle protein degradation (urinary 3-Methylhistidine by high performance liquid chromatography [HPLC]). Repeated measures ANOVA showed that strength, torque, lean tissue mass and 3- Methylhistidine increased with training (p<0.05), with no significant difference between groups. Both groups increased their 1-RM squat by 30% and 1-RM bench press by 13 .5%. The glutamine group had increases of 6% for knee extension torque, 5% for knee flexion torque, 2% for lean tissue mass and 41% for 3-Methylhistidine excretion. The placebo group increased knee extension torque by 2%, lean tissue mass by 1. 7% and 3-Methylhistidine by 56%. However, knee flexion torque decreased by 2%. We conclude that glutamine supplementation during resistance training has no significant effect on muscular performance, body composition or muscle protein degradation in young healthy adults.
