AbstractCreatine monohydrate (Cr) is perhaps one of the most widely used supplements taken in an attempt to improve athletic performance. The aim of this review is to update, summarise and evaluate the findings associated with Cr ingestion and sport and exercise performance with the most recent research available. Because of the large volume of scientific literature dealing with Cr supplementation and the recent efforts to delineate sport-specific effects, this paper focuses on research… 

Creatine Supplementation and Women Athletes

The purpose of this chapter was to examine the morphological potential for women to respond to Cr supplementation, and its effects on exercise performance and body composition.

Risk assessment for creatine monohydrate.

MUSCLE METABOLISM AND FATIGUE DURING SPRINT EXERCISE: EFFECTS OF CREATINE SUPPLEMENTATION

Research is needed to investigate and substantiate the effects of combining Cr supplementation with long term training on single and repeated sprints performance, and to show why even a small improvement may be important for competitive athletes.

Creatine Supplementation in Endurance Sports

Aside from the potential ergogenic benefits of caffeine, Cr is the most widely marketed nutritional supplement in the world and currently regarded as a true ergogenic aid.

Effect of different doses of creatine supplementation on endogenous creatine synthesis

The present study investigated the effect of supplementation with 0, 0.75, 1.0 and 6.0 g Cre/kg body weight per d for 4 weeks on L-AGAT activity and GAA concentration in the kidneys and total Cre in the gastrocnemius muscle in adult male Sprague-Dawley rats.

Creatine Supplementation Associated with Resistance Training Does Not Alter Renal and Hepatic Functions 03 ARTIGO RBME 526

It is concluded that creatine supplementation at the dosages used for healthy subjects during eight weeks does not alter hepatic or renal function, hence under the conditions of this study, creatine was considered safe.

Effects of creatine monohydrate supplementation on simulated soccer performance.

Acute short-term Cr supplementation has no beneficial effect on physical measures obtained during a 90-min soccer-simulation test, thus bringing into question its potential as an effective ergogenic aid for soccer players.

Muscle strength and muscle endurance: with and without creatine supplementation.

The results indicated that Muscle endurance was improved better in the EG and supplementation of creatine monohydrate supplements is useful to improve both muscular strength and muscular endurance.

The effects of Creatine Long-Term Supplementation on Muscle Morphology and Swimming Performance in Rats.

Long-term creatine supplementation increase muscle hypertrophy (but not body weight) and enhance endurance swimming performance in rats is suggested to have increased the number of muscle fibers and enhanced endurance swimmingperformance in rats.

Ergogenic dietary aids for the elderly

These studies have confirmed that creatine in older individuals, as in younger individuals, can increase the short-term capacity to perform quick, repeated episodes of intense activity, and further testing has involved the combinations of agents, such as creatine and caffeine, and combinations of b-hydroxy-b-methylbutyrate, showing some small improve- ments in physical function.

Effects of Creatine Supplementation on Exercise Performance

Creatinine is synthesised from the amino acids glycine, arginine and methionine in the kidneys, liver and pancreas, and is predominantly found in skeletal muscle, where it exists in 2 forms.

American College of Sports Medicine roundtable. The physiological and health effects of oral creatine supplementation.

Although Cr supplementation exhibits small but significant physiological and performance changes, the increases in performance are realized during very specific exercise conditions, suggesting that the apparent high expectations for performance enhancement, evident by the extensive use of Cr supplementation, are inordinate.

Oral Creatine Supplementation and Skeletal Muscle Metabolism in Physical Exercise

There is a shortage of scientific evidence concerning the adverse effects following creatine supplementation in healthy individuals even with long-term dosage, so creatine may be considered as a widespread, effective and safe ergogenic aid.

A Review of Creatine Supplementation: Side Effects and Improvements in Athletic Performance

It is recommended that children, adolescents, pregnant women, and people with diabetes or renal disease avoid creatine supplementation due to its unknown effects on these special populations.

In this article, scientific facts and considerations are presented, which support the concept of possible risks of uncontrolled supplementation in athletes with pure Cr.H2O overdosing, and a practical approach for detecting altered links in Cr metabolism and biosynthesis under conditions ofpure Cr.

Adverse Effects of Creatine Supplementation

There is no evidence for deleterious effects in healthy individuals of creatine supplementation, but idiosyncratic effects may occur when large amounts of an exogenous substance containing an amino group are consumed, with the consequent increased load on the liver and kidneys.

Effect of oral creatine supplementation on jumping and running performance.

The results show that Cr supplementation helps to prolong the time during which the maximal rate of power output could be maintained and the time of intensive running up to exhaustion improved by 13%.

The Effect of Creatine Supplementation on Anaerobic Performance in Moderately Active Men

The data suggest that Cr supplementation is ineffective in increasing performance in repeated, short-term, high-intensity anaerobic running.

Effects of 30 days of creatine ingestion in older men

The data suggest that 30 days of Cr-supplementation may have a beneficial effect on reducing muscle fatigue in men over the age of 60 years, but it does not affect body composition or strength.
