Changes in body composition, anaerobic power and muscular endurance of elite wrestlers after short and long duration of creatine consumption

The purpose of this study was to examine the efficacy of creatine consumption on body composition, anaerobic power and muscular endurance of elite wrestlers. Thirteen elite wrestlers (aged 21.09±2.91 years; height 175.63±3.97 cm; weight 78.6±4.6 kg) in a randomized and semi experimental design were divided into experimental (n=7) and control (n=6) groups. Experimental group ingested 20 grs CrM for 5 days and then 5grs CrM for 25 days; while control group in this period ingested placebo. Measurement of weight, fat percent (under skin fat of abdomen, triceps and Ilium), fat mass, fat free mass, upper body and lower body anaerobic power, muscle endurance of abdominal and shoulder muscles was measured in 3 phase (pre test, after 5 days and after 30 days). Data were analyzed by using Analysis variance repeated measure. Results showed that consumption of 20 gr /day creatine for 5 days (loading phase) result in significant increase in weight, fat free mass and upper body anaerobic power (P<0.05) and there was no significant change in fat percent, fat mass, lower body anaerobic power and muscle endurance (P>0.05). Consumption of 5 gr creatine per day for 25 days (maintenance phase) result in no significant change in any factors of study than loading phase (P>0.05). Notice to the results, It seems that creatine loading result in significant increase in weight, fat free mass and upper body anaerobic power of elite wrestler and however maintenance phase result in no significant increase in these factors, but remain loading phase changes.
