Performance of Repeated Cycling Sprints. Med. Sci. Sports Exerc., Vol. 36, No. 4, pp. 583 …

Oral supplementation with glycine-arginine-α-ketoisocaproic acid (GAKIC) has previously
been shown to improve exhaustive high-intensity exercise performance. There are no …

Background It has been demonstrated that acute GPLC supplementation produces
enhanced anaerobic work capacity with reduced lactate production in resistance trained …

Guanidinoacetic acid (GAA; also known as glycocyamine or guanidinoacetate) is the natural
precursor of creatine, and under investigation as a novel dietary agent. It was first identified …

Production of reactive oxygen species (ROS) during muscle contractions is associated with
muscle fatigue and damage in the short term and adaptive responses in the long term. When …

Background Dietary supplements containing L-arginine are marketed to improve exercise
performance, but the efficacy of such supplements is not clear. Therefore, this study …

The effect of a carbohydrate-arginine supplement on postexercise muscle glycogen storage
was investigated. Twelve well-trained cyclists rode for 2 hr on two separate occasions to …

Background Guanidinoacetic acid (GAA), a natural precursor of creatine, is a new promising
dietary supplement, yet its performance-enhancing effect, if any, has yet to be established …

This study examined the effect of amino acids in a carbohydrate beverage on cycling
performance. Twelve male athletes (28.5 pp2. 1 yr) cycled at 75% VO 2peak for 90 min …

Throughout history, athletes have searched for performance-enhancing agents. Recently,
creatine (N-[aminoiminomethyl]-N-methyl glycine) has been marketed as an ergogenic …
