PURPOSE To determine the effects of creatine (Cr) supplementation (20 g x d(-1) during 5 d) on maximal strength, muscle power production during repetitive high-power-output exercise bouts (MRPB), repeated running sprints, and endurance in handball players. METHODS Nineteen trained male handball players were randomly assigned in a double-blind fashion to either creatine (N = 9) or placebo (N = 10) group. Before and after supplementation, subjects performed one-repetition maximum half-squat… 

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.

The Effects of Creatine Monohydrate Loading on Anaerobic Performance and One-Repetition Maximum Strength

It is indicated that loading with 20 g·d−1 of CM for 7 days increased MP (5.4% increase) from the WAnT, but it had no effect on strength (1RM LE and 1RM BP), PP, or BW.

Creatine supplementation improves the anaerobic performance of elite junior fin swimmers.

It is indicated that five day Cr supplementation enhances the dynamic strength and may increase anaerobic metabolism in the lower extremity muscles, and improves performance in consecutive maximal swims in highly trained adolescent fin swimmers.

Short-term creatine supplementation has no impact on upper-body anaerobic power in trained wrestlers

These results suggest that 5-day CR supplementation has no impact on upper-body muscle anaerobic power output in consecutive UBISP an aerobic tests mimicking wrestling matches on a competition day.

Acute effect of betaine supplementation on muscular endurance during resistance exercise in trained men: a pilot and randomized study

Acute betaine supplementation had no effect on muscular endurance performance in the bench press and there were no significant differences in carbohydrates, protein, fat, or total energy consumption in weight training practitioners.

Supplementary Effect of Creatine on Cardiovascular Adaptation and Endurance Performance in Athletes

No significant change has been observed in resting heart, maximal heart rate, recoveryheart rate, body mass, body fat, fat free mass and blood lactate level in the experimental and control groups.

Creatine monohydrate appears to pose no serious health risks when taken at doses described in the literature and may enhance exercise performance in individuals that require maximal single effort and/or repetitive sprint bouts.

Contribution of creatine to protein homeostasis in athletes after endurance and sprint running

The findings suggest that creatine supplementation tended to decrease muscle glycogen and protein degradation, especially after endurance exercise, however, creatine supplementation might induce collagen proteolysis in athletes after sprint running.

Creatine supplementation and sprint performance in soccer players.

In conclusion, acute Cr supplementation favorably affected repeated sprint performance and limited the decay in jumping ability after the IET in highly trained soccer players.

Creatine supplementation enhances muscular performance during high-intensity resistance exercise.

Effects of creatine supplementation on body composition, strength, and sprint performance.

The addition of creatine to the glucose/taurine/electrolyte supplement promoted greater gains in fat/bone-free mass, isotonic lifting volume, and sprint performance during intense resistance/agility training.

Performance and muscle fiber adaptations to creatine supplementation and heavy resistance training.

Creatine supplementation enhanced fat-free mass, physical performance, and muscle morphology in response to heavy resistance training, presumably mediated via higher quality training sessions.

Effect of oral creatine supplementation on isokinetic torque production.

Based on within and between group comparisons, the authors were unable to detect an ergogenic effect of oral creatine supplementation on the decline in peak torque during isokinetic exercise at 180 degrees x s(-1).

Creatine supplementation enhances maximum voluntary isometric force and endurance capacity in resistance trained men.

Muscle hypertrophy in response to Cr supplementation and weight training may explain the findings of the present study.

Effect of oral creatine supplementation on muscle [PCr] and short-term maximum power output.

Findings suggest that 3 d of oral Cr supplementation does not increase resting muscle PCr concentration and has no effect on performance during a single short-term maximal cycling task.

Creatine supplementation increases muscle total creatine but not maximal intermittent exercise performance.

Despite the rise and washout of muscle TCr and CrP, maximal intermittent sprinting performance was unchanged by CrS, and no treatment (CrS) main effect was found on either variable.

Caffeine counteracts the ergogenic action of muscle creatine loading.

The data show that Cr supplementation elevates muscle PCr concentration and markedly improves performance during intense intermittent exercise, however, this ergogenic effect is completely eliminated by caffeine intake.

Creatine supplementation differentially affects maximal isometric strength and time to fatigue in large and small muscle groups.

It is suggested that CR supplementation can increase maximal strength and time to fatigue during isometric exercise, however, the improvements in maximal isometric strength following CR supplementation appear to be restricted to movements performed with a large muscle mass.
