Actually i disagree with the mono. He will get to much water retention especially in sports with the amount of water intake. And it's just more "weight" to carry around. Maybe can't afford to be more "bulky"
true but ive read articles that said that creatine has benefits for sports. heres the clip from the article I found on BN.com
2.5: What types of athletes can benefit from creatine supplementation?
The effects of creatine in many types of athletes has been researched, sometimes in sport-specific activities. Some of the various populations and exercises that have improved after creatine supplementation are listed here.
Weight lifting
Many studies have examined the effects of creatine on resistance training performance, using one rep maximum as the performance measure. A meta-analysis of sixteen placebo-controlled studies on resistance trained males published in 2002 found creatine supplementation to increase one rep maximum for bench press by an average of 15.07 lbs. and one rep maximum for squat by an average of 21.47 lbs. Another review looked at improvements in 1, 3, and 10 rep maximums following creatine supplementation and found an average of an 8% greater increase compared to placebo. The review also found an improvement of weight lifting performance measured by an increase in the number of repititions at a given percentage of maximal strength of 14% relative to placebo.
Swimming
The effect of creatine (.3 g/kg loading followed by 2.25 g maintenance) or placebo on swimming performance on 50 and 100 y sprints was measured in fifteen Division III swimmers. The subjects given creatine had improved performance compared to pre-supplementation on both events. Another study in junior swimmers found no improvement in single sprints from creatine supplementation, but did find an enhancement of swim bench test performance. Multiple other studies have also found creatine to improve swimming performance.
Soccer
A recent study examined the effects of three doses of 10 g creatine daily or placebo in twenty male soccer players over the course of seven days. Performance on a number of soccer-related tests was measured. Creatine improved performance on the dribble test, sprint-power test, and vertical jump test. These tasks rely primarily on the ATP-PCr system. Creatine failed to improve endurance performance in these subjects. The authors concluded that creatine improved soccer-specific skills in young soccer players. Four previous studies have also found impoved performance on similar tests from creatine supplementation in highly trained soccer players.
Cycling
A number of studies have found creatine to improve cycling performance, especially sprint performance followed by short rest periods. Additionally, creatine may even improve endurance cycling performance.
Sprinting
Creatine appears to improve sprint performance, but not to the same degree as most other forms of exercise. While some studies indicate a benefit, others do not. It is possible that the increase in body mass makes a larger difference here.
Rowing
A study examined the effect of creatine (20 g daily) or placebo for five days on exercise tests in elite rowers. It found that creatine increased the exercise time for anaerobic exercise against a constant load in this study population. However, another study did not find an improvement from creatine supplementation in a high intensity rowing and strength program.
Wrestling
In one study, 20 international level wrestlers were given creatine (four doses of 5 g daily) or placebo and underwent Wingate anaerobic tests. There was significant improvement after supplementation with creatine, but not placebo.
edit- baseball isnt in here but the same concept applies.
