It has been reported that abundant nitric oxide content in endothelial cells can increase exercise performance. The purpose of this study was to evaluate the potential beneficial effects of a combined extract comprising L-arginine, L-glutamine, vitamin C, vitamin E, folic acid, and green tea extract LVFG on nitric oxide content to decrease exercise fatigue. Antifatigue activity and exercise performance were evaluated using forelimb grip strength, exhaustive swimming test, and levels of serum lactate, ammonia, glucose, and creatine kinase CK after an acute swimming exercise.

Online ahead of Print ; 10 2 :e Background: Football players often experience muscle fatigue leading to impaired performance in the middle of the game. Watermelon contains citrulline which may detox ammonia and lactic acid in the urea cycle thus could help relieve muscle fatigue. Objectives: This study analyzed the effect of watermelon beverage ingestion on fatigue index FI in young-male, recreational football players. Methods: A randomized, 2-periods crossover design involving 26 young-male, recreational football players aged 15 - 17 years was performed. They consumed mL of watermelon beverage in 1 of the 2 periods, and mL of red sucrose syrup as placebo in the other for 7 days respectively.

Metrics details. Many human studies report that nitric oxide NO improves sport performance. This is because NO is a potential modulator of blood flow, muscle energy metabolism, and mitochondrial respiration during exercise. L-Citrulline is an amino acid present in the body and is a potent endogenous precursor of L-arginine, which is a substrate for NO synthase. Here, we investigated the effect of oral L-citrulline supplementation on cycling time trial performance in humans. A double-blind randomized placebo-controlled 2-way crossover study was employed.

Elizabeth A. Applegate, Louis E. The premise and promise of ergogenic aid use is rooted in antiquity and is based upon superstition and ritualistic behavior of athletes who perceive that past performances were predicated upon unique dietary constituents or dietary manipulation. Accounts from ancient times recommended that athletes and soldiers preparing for battle consume specific animal parts to confer agility, speed or strength associated with that animal. Ergogenic aids such as alkaline salts, caffeine, carbohydrate and protein have been used by athletes with variable success. As nutritionists and exercise physiologists discovered and perfected the scientific understanding of metabolic reactions, athletes in turn experimented with the amount, form and timing of administration in the search for optimal performance.

The ergogenic response of L-citrulline or L-arginine supplements depends on the training status of the subjects. Studies involving untrained or moderately healthy subjects showed that NO donors could improve tolerance to aerobic and anaerobic exercise.

Clin Sci Lond 25 April ; 8 : — Background: Exercise and citrulline CIT are both regulators of muscle protein metabolism. However, the combination of both has been under-studied yet may have synergistic effects on muscle metabolism and performance.

Oral l -citrulline Cit increases plasma l -arginine Arg concentration and the production of nitric oxide NO. NO dilates blood vessels and potentially improves sports performance. Seven days of oral Citrulline 1. Nitric oxide NO dilates blood vessels, enhancing circulation and improving mitochondrial efficiency Albrecht et al. In addition, NO exerts a range of physiological functions [e. Therefore, efforts have been directed towards strategies that promote NO production. Arg is a conditionally essential amino acid that exerts various physiological actions by improving vascular endothelial Bode-Boger et al.

Exercise, sports nutrition, dietary supplements, nitric oxide, arginine, citrulline, ornithine, cocoa, caffeine, recovery. Background: The beneficial effect of popular supplements and use of nitric oxide NO precursor nutrients in athletes which aim at increase of sports performance. Objective: The aim of this study is to investigate the effect of nitric oxide precursor nutrients and some nutrients with the ability to increase NO levels in the body on increased NO production in metabolism and on the recovery after acute exercise. Materials and Methods: 8 volunteers, male athletes, in shape and trained participated into this study. Athletes were subject to research protocol every other day, a total of three times. Heart rate and lactate levels were determined at resting and recovery.

Arginine is a conditionally essential amino acid that is involved in protein synthesis, the detoxification of ammonia, and its conversion to glucose as well as being catabolized to produce energy. In addition to these physiological functions, arginine has been purported to have ergogenic potential. Athletes have taken arginine for three main reasons: 1 its role in the secretion of endogenous growth hormone; 2 its involvement in the synthesis of creatine; 3 its role in augmenting nitric oxide. These aspects of arginine supplementation will be discussed as well as a review of clinical investigations involving exercise performance and arginine ingestion.
