אני לא ראיתי "הוכחות" שגלוטמין לא יעיל...? ועל כל מחקר שתביא אני יכול להביא לך מחקר שאומר שכן יעיל...
ובגדול
כל הספורט הזה אינדיווידואלי יש כאלה שישפיע עליהם יש כאלה שלא....
לי הגלוטמין עוזר מאוד באתאוששות...
לפוסט.. עד שלא תנסה על עצמך לא תדע....

אני מחכה למחקר שאומר שהוא כן יעיל לכל מחקר שהבאתי לך כאן:

The purpose of this study was to assess the effect of oral glutamine supplementation combined with resistance training in young adults. A group of 31 subjects, aged 18-24 years, were randomly allocated to groups (double blind) to receive either glutamine (0.9 g x kg lean t:):):)ue mass(-1) x day(-1); n = 17) or a placebo (0.9 g maltodextrin x kg lean t:):):)ue mass(-1) x day(-1); n = 14 during 6 weeks of total body resistance training. Exercises were performed for four to five sets of 6-12 repetitions at intensities ranging from 60% to 90% 1 repetition maximum (1 RM). Before and after training, measurements were taken of 1 RM squat and bench press strength, peak knee extension torque (using an isokinetic dynamometer), lean t:):):)ue mass (dual energy X-ray absorptiometry) and muscle protein degradation (urinary 3-methylhistidine by high performance liquid chromatography). Repeated measures ANOVA showed that strength, torque, lean t:):):)ue mass and 3-methylhistidine increased with training (P < 0.05), with no significant difference between groups. Both groups increased their 1 RM squat by approximately 30% and 1 RM bench press by approximately 14%. The glutamine group showed increases of 6% for knee extension torque, 2% for lean t:):):)ue mass and 41% for urinary levels of 3-methylhistidine. The placebo group increased knee extension torque by 5%, lean t:):):)ue mass by 1.7% and 3-methylhistidine by 56%. We conclude that glutamine supplementation during resistance training has no significant effect on muscle performance, body composition or muscle protein degradation in young healthy adults.

No one can argue that glutamine has an anti-catabolic/anabolic effect in critically ill patients. In healthy, weight training athletes glutamine supplementation has failed to show any effect on lean body mass or strength. The studies are small and few and usually of fairly short term.
