“…Oral supplementation of glutamine (0.35g/kg/day) by 15 non-athlete male students for 8 weeks, caused significantly greater increases in upper and lower body strength, explosive muscular power, blood testosterone, GH and IGF-1 when compared to the placebo group. Furthermore, in the study group there was improved body composition (increased body mass, fat-free mass and reduced body fat) and vertical jump (62.31 ± 5.22 pre-and 67.11 ± 4.44 post-supplementation) [79]. Glutamine supplementation plays a key role in recovery after muscle injury.…”

Glutathione (γ-L-glutamyl-L-cysteinyl-glycine, GSH) plays a very important role in physical exercise by controlling the level of oxidative stress. It is the major endogenous intracellular antioxidant and currently one of the most studied substances of this class. It is synthesized primarily in the hepatic cells and has numerous physiological functions, including protection of cells against oxidative stress, detoxication of toxins and carcinogens, posttranslational regulation of protein function, and maintenance of immune function of the immune system. In human body, GSH is

“…The independent sample t-test in table II showed that glutamine administration affects the vertical jump results 48 hours after hitting the jumping smash. In their research, Hakimi et al (2012) stated that the vertical jump results were better in the group given glutamine than placebo [22].…”

The purpose of this study was to determine the effect of glutamine supplementation on the ability of vertical jump and smash velocity after badminton's jumping smash. The research used a pre-post two-group design using 20 trained male athletes from the State University of Surabaya. The research sample was divided into two groups: the Placebo (PLA) group, which was given exercise + mineral water, and the glutamine (GLU) group, which was given training + glutamine supplement. The movement provided is to do a jumping smash for 20 repetitions, ten sets with 30-second intervals. Glutamine dose of 0.4 gram/Kg BW was given 1 hour after jumping smash activity, 24 hours, and 48 hours after jumping smash activity (3 times). The data collection instrument was a vertical jump test using an MD jump, while the smash velocity was measured using a Bushnell 101922 radar gun. Independent sample t-test showed significant Δ pre-post2 and Δ post1-post2 on the vertical jump variable (p<0.05). On the smash velocity variable, effective results were demonstrated in Δ pre-post3 and Δ post1-post3. In conclusion, glutamine supplementation for three days could improve the vertical jump ability at 48 hours and smash velocity at 72 hours.

“…The GLA-GLN relationship also plays a vital role in muscular metabolism, as GLN is stored and released predominantly by the skeletal muscle [18]. Also, it is the most abundant non-essential amino acid in human muscle [19]. The skeletal muscle amino acid metabolism generates GLN to detoxify the ammonia produced at this level [18].…”

“…Because of its immunomodulatory role, GLN is widely used in sports nutrition as a food supplement [20]. An experimental study concluded that GLN supplementation increases muscular power and strength and enhances performance during resistance training [19]. Also, sports recovery acceleration and muscular fatigue reduction are essential for sports performance.…”

Monosodium glutamate (MSG) is the sodium salt of glutamic acid (GLA), used as a flavour enhancer. MSG is considered a controversial substance. It is incriminated in disturbing the antioxidant system, but also has beneficial effects, as GLA metabolism plays a crucial role in homeostasis. This study highlights which positive or negative aspects of MSG sub-chronic consumption are better reflected in subjects potentially affected by advanced age. Daily doses of MSG were administered to four groups of two-year-old Wistar rats for 90 days: (I) 185 mg/kg bw, (II) 1500 mg/kg bw, (III) 3000 mg/kg bw and (IV) 6000 mg/kg bw, compared to a MSG non-consumer group. Aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, direct and total bilirubin, total cholesterol, triglycerides, creatinine and urea levels were analysed; stomach, liver and kidney samples were subjected to histopathological analysis. Although, in most cases, there were no statistical differences, interesting aspects of the dose–effect relationship were observed. After MSG sub-chronic consumption, the positive aspects of GLA seem to be reflected better than the negative ones. The hormesis effect, with low-level reactive oxygen species’ protective effects and GLA metabolism, may represent the hypothesis of a potential defence mechanism triggered by MSG sub-chronic consumption in ageing rats.
