The purpose of this investigation was to determine if creatine supplementation assisted with reducing the amount of exercise induced muscle damage and if creatine supplementation aided in recovery from exercise induced muscle damage. Two groups of subjects (group 1 = creatine; group 2 = placebo) participated in an eccentric exercise protocol following 7 and 30 days of creatine or placebo supple...
A large number of studies have been published on creatine supplementation over the last decade. Many studies show that creatine supplementation in conjunction with resistance training augments gains in muscle strength and size. The underlying physiological mechanism(s) to explain this ergogenic effect remain unclear. Increases in muscle fiber hypertrophy and myosin heavy chain expression have b...
Creatine monohydrate has become one of the most popular ergogenic sport supplements used today. It is a nonessential dietary compound that is both endogenously synthesized and naturally ingested through diet. Creatine ingested through supplementation has been observed to be absorbed into the muscle exclusively by means of a creatine transporter, CreaT1. The major rationale of creatine supplemen...
conclusions beta-alanine supplementation has limited antioxidant effect during the repeated wts. background carnosine is a dipeptide formed from the β-alanine and histidine amino acids and found in mainly in the brain and muscle, especially fast twitch muscle. carnosine and creatine has an antioxidant effect and carnosine accounts for about 10% of the muscle's ability to buffer the h+ ions prod...
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...
Although physical activity and creatine supplementation have been a documented beneficial effect on neurological disorders, its implications for epilepsy are still controversial. Thus, we decided to investigate the effects of 6 weeks swimming training, creatine supplementation (300 mg/kg; p.o.) or its combination seizures and neurochemical alterations induced by pentylenetetrazol (PTZ). We foun...
PURPOSE To assess the effects of creatine supplementation, associated or not with strength training, upon emotional and cognitive measures in older woman. METHODS This is a 24-week, parallel-group, double-blind, randomized, placebo-controlled trial. The individuals were randomly allocated into one of the following groups (n=14 each): 1) placebo, 2) creatine supplementation, 3) placebo associa...
Most research on creatine has focused on short-term creatine loading and its effect on high-intensity performance capacity. Some studies have investigated the effect of prolonged creatine use during strength training. However, studies on the effects of prolonged creatine supplementation are lacking. In the present study, we have assessed the effects of both creatine loading and prolonged supple...
The effect of dietary creatine and supplementation on skeletal muscle creatine accumulation and subsequent degradation and on urinary creatinine excretion was investigated in 31 male subjects who ingested creatine in different quantities over varying time periods. Muscle total creatine concentration increased by approximately 20% after 6 days of creatine supplementation at a rate of 20 g/day. T...
Creatine is one of the most popular nutritional ergogenic aids for athletes. Studies have consistently shown that creatine supplementation increases intramuscular creatine concentrations which may help explain the observed improvements in high intensity exercise performance leading to greater training adaptations. In addition to athletic and exercise improvement, research has shown that creatin...
