A survey was conducted to examine the source of information and usage of nutritional supplements in 115 male and 88 female varsity athletes at a Division I university. The survey asked each athlete to define supplement, and report supplement use and type, source of information, and reasons for use. Supplement use frequencies were determined, and comparisons were made between gender and sport. E...

During the past decade, the nutritional supplement creatine monohydrate has been gaining popularity exponentially. Introduced to the general public in the early 1990s, shortly after the Barcelona Olympic Games, creatine (Cr) has become one of the most widely used nutritional supplements or ergogenic aids, with loading doses as high as 20-30 g·day(-1) for 5-7 days typical among athletes. This pa...

Creatine is an amino acid derivate commonly found in vertebrate muscle tissue. facilitates the recycling of adenosine triphosphate and thus contributes to energy supply muscles as well brain. used a supplement for several reasons its effects humans, particularly sports medicine, have been studied excessively. Also, creatine supplementation has functions benefits terrestrial farm animals. Up dat...

Athletes widely use nutritional supplements to increase muscle strength and endurance. This review aims summarize the effects of commonly used dietary on endurance in athletes. A literature search identified several studied for their impact performance, including protein supplements, creatine, beta-alanine, branched-chain amino acids (BCAAs), caffeine, nitrates, vitamins minerals. The discussed...

Whey protein is a nutritional supplement commonly ingested for recovery following exercise. However, the timing when whey protein supplement must be ingested after muscle-damaging exercise is debatable. Therefore, the present study investigated the effects of the timing of supplement ingestion on muscle damage markers after eccentric or muscle-damaging exercise. In total, 32 collegiate male stu...

You might say the knowledge base on the effects of creatine is a bit? slim. About half of the creatine humans need is made in the body by the liver and kidneys. Outside of the body, the other half is typically obtained from a person?s diet (from eating red meat and seafood). There are also creatine supplements in many forms, including powders, tablets, liquids, and energy bars. Though the use o...

BACKGROUND The objective was to study nutritional supplement use among young elite UK athletes to establish whether a rationale versus practice incongruence exists, and to investigate the sources of information. Survey data were analysed for association between supplements used and motives for using such substances among young athletes along with the sources of advice and literature precedents ...

While the role of creatine in preventing muscle (peripheral) fatigue for high performance athletes is well understood, its biochemical role in prevention of mental (central) fatigue is not. Creatine is abundant in muscles and the brain and after phosphorylation used as an energy source for adenosine triphosphate synthesis. Using double-blind placebo-controlled paradigm, we demonstrated that die...
