Creatine has become a popular nutritional supplement among athletes. Recent research has also suggested that there may be a number of potential therapeutic uses of creatine. This paper reviews the available research that has examined the potential ergogenic value of creatine supplementation on exercise performance and training adaptations. Review of the literature indicates that over 500 research studies have evaluated the effects of creatine supplementation on muscle physiology and/or exercise… Expand
Creatine supplementation with specific view to exercise/sports performance: an update
TLDR
Although presently ingesting creatine as an oral supplement is considered safe and ethical, the perception of safety cannot be guaranteed, especially when administered for long period of time to different populations (athletes, sedentary, patient, active, young or elderly). Expand
Scientific basis and practical aspects of creatine supplementation for athletes.
TLDR
The predominance of research indicates that creatine supplementation represents a safe, effective, and legal method to enhance muscle size and strength responses to resistance training. Expand
Sports Applications of Creatine
TLDR
In regard to athletes, creatine has continually proved itself to be one of the most effective and safe nutritional supplements to increase strength, muscle mass, and performance. Expand
Creatine Use in Sports
TLDR
While creatine appears to be safe and effective for particular settings, whether creatine supplementation leads to improved performance on the field of play remains unknown. Expand
Beyond muscles: The untapped potential of creatine.
TLDR
There is evidence to suggest that individuals with certain neurological conditions may benefit from exogenous creatine supplementation if treatment protocols can be optimized and there is increasing evidence that creatine may have a regulatory impact on the immune system. Expand
MECHANISMS OF MUSCULAR ADAPTATIONS TO CREATINE SUPPLEMENTATION
TLDR
Creatine supplementation may alter skeletal muscle directly, by increased muscle glycogen and phosphocreatine, faster phosphocreatedine resynthesis, increased expression of endocrine and growth factor mRNA, or indirectly, through increased training volume. Expand
Creatine supplementation improves performance, but is it safe? Double-blind placebo-controlled study.
TLDR
Despite the expected weight increase, the creatine monohydrate supplementation is safe for health and no detrimental effects on different organs and physiological systems were observed in the cohort of volunteers. Expand
Creatine for Exercise and Sports Performance, with Recovery Considerations for Healthy Populations
TLDR
The purpose of this review was to summarize the existing literature surrounding the efficacy of creatine supplementation on exercise and sports performance, along with recovery factors in healthy populations. Expand
Creatine Supplementation
Creatine monohydrate is a dietary supplement that increases muscle performance in short-duration, high-intensity resistance exercises, which rely on the phosphocreatine shuttle for adenosineExpand
International Society of Sports Nutrition position stand: safety and efficacy of creatine supplementation in exercise, sport, and medicine
TLDR
An update to the current literature regarding the role and safety of creatine supplementation in exercise, sport, and medicine is provided and the position stand of International Society of Sports Nutrition (ISSN) is updated. Expand

Creatine supplementation and exercise performance: an update.
TLDR
Short-term creatine supplementation appears to increase body mass in males, although the initial increase is most likely water, and chronic creatine supplementation, in conjunction with physical training involving resistance exercise, may increase lean body mass, however, confirmatory research data are needed.

Oral Creatine Supplementation and Athletic Performance: A Critical Review

TLDR
In laboratory settings, creatine supplementation is ergogenic in repeated 6–30-second bouts of maximal stationary cycling sprints and suggests that creatine improves strength, possibly by increasing myofibrillar protein synthesis; however, more study is needed to prove this. Expand
Creatine supplementation as an ergogenic aid for sports performance in highly trained athletes: a critical review.
TLDR
The widespread use of creatine ingestion to improve competition performance does not seem to be justified and the potential interest of creatine supplementation for elite athletes could be related to an increased ability to perform repeated high-intensity exercise bouts, either during training or during competition in sports in which repeated efforts are required. Expand
Long-Term Effects of Creatine Monohydrate on Strength and Power
TLDR
The results indicate that 10 weeks of creatine monohydrate supplementation while participating in a resistance training program significantly increases strength and power indices compared with placebo supplementation, and indicates that lower doses of Creatine monohydrate may be ingested, without a short-term, large-dose loading phase, for an extended period to achieve significant performance enhancement.

TLDR
Future studies will be required to address the potential for creatine monohydrate supplementation to attenuate age-related muscle atrophy and strength loss, as well as to protect against age-dependent neurodegenerative disorders such as Parkinson's disease and Alzheimer's disease. Expand
Long-term creatine intake is beneficial to muscle performance during resistance training.
TLDR
It is concluded that long-term creatine supplementation enhances the progress of muscle strength during resistance training in sedentary females. Expand
The Effect of Creatine Supplementation on Anaerobic Performance in Moderately Active Men
The effect of creatine monohydrate (Cr) supplementation on anaerobic performance was investigated in 21 (treatment = 11; placebo = 10) moderately active males. Supplementation included 20 g·d−1 of CrExpand
Creatine monohydrate supplementation enhances high-intensity exercise performance in males and females.
TLDR
It is concluded that short-term Cr supplementation can increase indices of high-intensity exercise performance for both males and females. Expand
Creatine: a review of efficacy and safety.
TLDR
While creatine may enhance the performance of high-intensity, short-duration exercise, it is not useful in endurance sports and consumers should balance the quality of information supporting the use of creatine with the known and theoretical risks of using the product, including possible renal dysfunction. Expand
Performance and muscle fiber adaptations to creatine supplementation and heavy resistance training.
TLDR
Creatine supplementation enhanced fat-free mass, physical performance, and muscle morphology in response to heavy resistance training, presumably mediated via higher quality training sessions. Expand
