EFFECTS OF CREATINE SUPPLEMENTATION ON MUSCULAR FITNESS OF HOCHIMINH CITY BASKETBALL PLAYERS AFTER 8-WEEK OF RESISTANT TRAINING

Abstract

The purpose of this research was to examine the effect of creatine monohydrate supplementation on muscle fitness of Ho Chi Minh City (HCMC) basketball players after 8 weeks of resistant training. In this study twelve male athletes of Ho Chi Minh basketball utilized a two–group match. Randomly assigned design in a single-blind fashion to either creatine (n=6, mean age: 25.50±2.95 years) or placebo (n=6, mean age: 23.83± 4.12 years) group with 8 weeks of resistant training was measured for muscular fitness: muscular strength used 1-RM testing for upper body strength (bench press test), leg strength (leg press test), handgrip test, and Sergeant jump test; muscular power used Wingate Anaerobic 30 cycle Test to evaluate Peak Power Output (PP); muscular endurance used Curl Up Test to evaluate abdominal strength. All data were analyzed by computer statistical program. Significant level was set at 0.05

The results of this study showed that there was a significant difference between creatine (105.00±13.784 kg) and Placebo group (85.00 ±15.166 kg) in mean bench press leg press (218.33±23.166(kg); 191.67±13.292 kg) and peak power (898.283±63.590 W; 831.000±32.437 W), relative peak power (11,967±0.585 W/kg; 10.917±0.741W/kg) and anaerobic capacity (9.517±0.256 W/kg; 9.000±0.410 W/kg). The muscular endurance was not statistically significant difference. It was concluded that after 8 weeks using creatine supplementation combined with resistant training and Creatine supplementation did not effect on muscular endurance, but had differences in the aspect of statistic significance in muscular strength and muscular power of HCMC basketball athletes.
