Potential ergogenic effects of arginine and creatine supplementation.
The rationale for the use of nutritional supplements to enhance exercise capacity is based on the assumption that they will confer an ergogenic effect above and beyond that afforded by regular food ingestion alone. The proposed or advertised ergogenic effect of many supplements is based on a presumptive metabolic pathway and may not necessarily translate to quantifiable changes in a variable as...
متن کاملThe Ergogenic Potential of Arginine
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 g...
متن کاملErgogenic effects of betaine supplementation on strength and power performance
BACKGROUND We investigated the ergogenic effects of betaine (B) supplementation on strength and power performance. METHODS Twelve men (mean +/- SD age, 21 +/- 3 yr; mass, 79.1 +/- 10.7 kg) with a minimum of 3 months resistance training completed two 14-day experimental trials separated by a 14-day washout period, in a balanced, randomized, double-blind, repeated measures, crossover design. Pr...
متن کاملErgogenic effects of quercetin supplementation in trained rats
UNLABELLED BACKGROUND Quercetin is a natural polyphenolic compound currently under study for its ergogenic capacity to improve mitochondrial biogenesis. Sedentary mice have exhibited increased endurance performance, but results are contradictory in human models. METHODS We examined the effects of six weeks of endurance training and quercetin supplementation on markers of endurance performa...
متن کاملSide effects of creatine supplementation in athletes.
CONTEXT Allegations about side effects of creatine supplementation by athletes have been published in the popular media and scientific publications. PURPOSE To examine the experimental evidence relating to the physiological effects of creatine supplementation. RESULTS One of the purported effects of oral creatine supplementation is increased muscle mass. A review of the literature reveals a...
