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.

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.

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. LVFG supplementation dose-dependently improved exercise performance and nitric oxide content, and it dose-dependently decreased serum ammonia and CK activity after exhaustive swimming test. Taken together, our results show that LVFG could have the potential for alleviating physical fatigue due to its pharmacological effect of increasing serum nitric oxide content. Nitric oxide synthases NOS are enzymes containing heme prosthetic groups, which are responsible for the synthesis of NO from L-arginine [ 1 , 2 ].

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. Twenty-two trained males consumed 2.

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. Arginine is a basic amino acid and is classified as a conditionally essential amino acid.

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. Maximal endurance activity and body composition were assessed, and muscle protein metabolism protein synthesis, proteomic approach and energy metabolism [energy expenditure, mitochondrial metabolism] were explored. Results: Body composition was affected by exercise but not by CIT supplementation. Mitochondrial metabolism was modulated by exercise but not directly by CIT supplementation. However, the proteomic approach demonstrated that CIT supplementation was able to affect energy metabolism, probably due to activation of pathways generating acetyl-CoA.

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.

 Какой-то турист. - Вы уверены. - Туризм - моя профессия! - отрезал Клушар.  - Я их сразу узнаю.

Голый ландшафт испанской нижней Эстремадуры бежал за окном, слившись в неразличимый фон, затем замедлил свой бег. - Мистер Беккер! - послышался голос.  - Мы на месте. Беккер встал и потянулся.

В таком случае ему не нужно будет передавать пароль кому-то. Возможно, он работал в одиночку. Стратмор хмыкнул. Мысль Сьюзан показалась ему достойной внимания.

Ясно, конечно, что это никакой не полицейский, это Клиент с большой буквы.  - Дайте мне угадать: наш номер вам дал приятель. Сказал, чтобы вы обязательно нам позвонили.
