- 1From: Journal of the International Society of Sports Nutrition. (Vol. 9, Issue 1) Peer-ReviewedBackground We examined the effect of four weeks of [beta]-alanine supplementation on isometric endurance of the knee extensors at 45% maximal voluntary isometric contraction (MVIC). Methods Thirteen males (age...
- 2From: Journal of the International Society of Sports Nutrition. (Vol. 9, Issue 1) Peer-ReviewedBackground Probiotics are an upcoming group of nutraceuticals claiming positive effects on athlete's gut health, redox biology and immunity but there is lack of evidence to support these statements. Methods We...
- 3From: Journal of the International Society of Sports Nutrition. (Vol. 9, Issue 1) Peer-ReviewedThe purpose of this study was: aim 1) compare insulin and leucine serum responses after feeding a novel hydrolyzed whey protein (WPH)-based supplement versus a whey protein isolate (WPI) in rats during the...
- 4From: Journal of the International Society of Sports Nutrition. (Vol. 9, Issue 1) Peer-ReviewedBackground Exercise is an excellent tool to study the interactions between metabolic stress and the immune system. Specifically, high-intensity exercises both produce transient hyperammonemia and influence the...
- 5From: Journal of the International Society of Sports Nutrition. (Vol. 9, Issue 1) Peer-ReviewedBackground It has been shown that supplementation with creatine (Cr) and glycerol (Gly), when combined with glucose (Glu) necessary for the enhancement of Cr uptake by skeletal muscle, induces significant...
- 6From: Journal of the International Society of Sports Nutrition. (Vol. 9, Issue 1) Peer-ReviewedBackground Intracellular concentrations of adenosine-5'-triphosphate (ATP) are many times greater than extracellular concentrations (1-10 mM versus 10-100 nM, respectively) and cellular release of ATP is tightly...
- 7From: Journal of the International Society of Sports Nutrition. (Vol. 9, Issue 1) Peer-ReviewedBackground A growing consumption of natural (plant-derived) dietary supplements with ergogenic aims, with particular regard for ecdysteroids, phytoestrogen s and vegetal sterols, has been registered over the last...
- 8From: Journal of the International Society of Sports Nutrition. (Vol. 9, Issue 1) Peer-ReviewedBackground [beta]-alanine supplementation has been shown to improve high-intensity exercise performance and capacity. However, the effects on intermittent exercise are less clear, with no effect shown on repeated...
- 9From: Journal of the International Society of Sports Nutrition. (Vol. 9, Issue 1) Peer-ReviewedBackground Creatine monohydrate (CrM) has been consistently reported to increase muscle creatine content and improve high-intensity exercise capacity. However, a number of different forms of creatine have been...
- 10From: Journal of the International Society of Sports Nutrition. (Vol. 9, Issue 1) Peer-ReviewedBackground Although dietary supplements (DSs) in sports are considered a natural need resulting from athletes' increased physical demands, and although they are often consumed by athletes, data on DS usage in Olympic...
- 11From: Journal of the International Society of Sports Nutrition. (Vol. 9, Issue 1) Peer-ReviewedCreatine is one of the most popular and widely researched natural supplements. The majority of studies have focused on the effects of creatine monohydrate on performance and health; however, many other forms of creatine...
- 12From: Journal of the International Society of Sports Nutrition. (Vol. 9, Issue 1) Peer-ReviewedBackground Previous studies reported divergent results on nutraceutical actions and free radical scavenging capability of ginseng extracts. Variations in ginsenoside profile of ginseng due to different soil and...
- 13From: Journal of the International Society of Sports Nutrition. (Vol. 9, Issue 1) Peer-ReviewedBackground Soccer is a form of exercise that induces inflammatory response, as well as an increase in free radicals potentially leading to muscle injury. Balanced nutritional intake provides important antioxidant...
- 14From: Journal of the International Society of Sports Nutrition. (Vol. 9, Issue 1) Peer-ReviewedPurpose To determine the effects of 16 wk. of beta-hydroxy-beta-methylbutyrate (HMB) administration on age-related changes in functionality and diffusion tensor imaging (DTI) determined myofiber dimensions....
- 15From: Journal of the International Society of Sports Nutrition. (Vol. 9, Issue 1) Peer-ReviewedBackground Dietary creatine has been largely used as an ergogenic aid to improve strength and athletic performance, especially in short-term and high energy-demanding anaerobic exercise. Recent findings have also...
- 16From: Journal of the International Society of Sports Nutrition. (Vol. 9, Issue 1) Peer-ReviewedBackground Although studies have investigated the effects of hydration on performance measures, few studies have investigated how the temperature of the ingested liquid affects performance and core temperature during...
- 17From: Journal of the International Society of Sports Nutrition. (Vol. 9, Issue 1) Peer-ReviewedBackground Nutritional supplements designed to increase adenosine 5'-triphosphate (ATP) concentrations are commonly used by athletes as ergogenic aids. ATP is the primary source of energy for the cells, and...
- 18From: Journal of the International Society of Sports Nutrition. (Vol. 9, Issue 1) Peer-ReviewedBackground Dietary supplements containing L-arginine are marketed to improve exercise performance, but the efficacy of such supplements is not clear. Therefore, this study examined the efficacy of acute ingestion of...
- 19From: Journal of the International Society of Sports Nutrition. (Vol. 9, Issue 1) Peer-ReviewedBackground Resistance training (RT) enhances muscle protein synthesis and hypertrophy while increasing strength and power.
