For this reason, there was interest in determining if creatin subjunction may help hyper-hydrate an athlete and/or improve read attitude when exertion in the heat [76, 115,116,117,118,119,120,121,122,123,124,125,126]. Studies have consistently shown that creatine supplementation increases intramuscular creatine concentrations, can improve employment performance, and/or improve training adaptations. Supplements are also taken to increase creatine in the brain. While in general creatine expanding upon resulted in slightly elevated creatinine levels that remained within normal limits, supplementation did not induce renal damage (P value< 0.
