摘要:The purpose of this study is to find the effects of Creatin Monohydrate (CrH2O) on athlete performance (isokinetic power measured as a total workout) used as an ergojenic aid in long-term (6 weeks) supplementation. There are 38 participants willing to join to the study. Their ages are between 20 and 27. All of them are choosed from active athletes. From the findings of this study; all the participants’ in the creatin group have increased the total workout production in all cycles of isokinetic exercise. The difference between the values in the first and fifth cycles, (both before and after loading) are statistically significant. In the creatin group the difference between before loading and 15th day values are statistically significant. But the difference between before loading and 50th day values does not have statistical difference. In placebo group, before and after values in all 5 cycles, there is no statistical difference between the total workout production values. There is also no statistical difference between the before loading and 15th day values. As the same there is no statistical difference between the before loading and the 50th day values. The most important finding in this study is that, there is no affect of long term creatin loading (50 days) on maximal voluntary knee extansion, as a total muscle workout values. But the change in values before loading day and 15th day are significantly improved. And so we understand that, for getting better results in total workout production, we better use two weeks period loading instead of long term loading.
