Effects Of Aerobic Exercise And Creatine Monohydrate Supplementation On Oxidative Stress And Body Composition In Athletes

The purpose of the present study was to examine the effects of 7 days creatine monohydrate (CrM) supplementation on lipid peroxidation and body composition after aerobic exercise to exhaustion in athletes. Therefore, thirty one young male wrestlers (age 19.52±2.75 years, body mass 79.24±16.13 kg, height 173±6.49 cm, and body fat 16.37±5.92 %) volunteered to participate in this double-blind, placebo controlled study and were randomly placed into either placebo (PL; 4 × 5 g.day-1 of maltodextrine powder; n=16) or creatine monohydrate (CrM: 4 × 5 g.day-1 CrM, n=15) groups. Prior to and following supplementation, subjects performed aerobic exercise to exhaustion on cycle ergometer. Urine samples were collected before (Pre), after (Post) and 24 h after (24h Post) exercise tests to determine lipid peroxidation. We observed a non-significant trend toward a small increase in lipid peroxidation by 0.43% in CrM and 3.06% in PL group after exercise to exhaustion in young wrestlers (p>0.05). significant increases were observed in body mass (3.71 %), soft lean mass (4.04%), intracellular fluid (3.9%) and extracellular fluid (4.28%) (P<0.05). The results of this study showed that short-term CrM supplementation didn’t affect on lipid peroxidation induced by aerobic exercise to exhaustion but, short-term CrM supplementation improved wrestlers’ body composition.
