Effects of Creatine Supplementation on Muscular Strength and Anaerobic Performance

Abstract

Background and Study Aim: Designation amongst the ergogenic aids, Creatine supplementation is a widespread and significantly researched option in gaining muscular strength and anaerobic performance. This paper is an endeavor to assess the implications of creatine supplement on muscular strength and anaerobic performance among trained athletes. Although existing literature has shown considerable gains in the field of strength training, few literature has been devoted to the study of anaerobic capacity that is vital in regard to performance in short-duration high-yield tasks. Material and Methods: This was a randomized, double-blind, placebo-controlled trial of 40 male collegiate athletes (18-30 years old) that participated in routine resistance training. The participants were grouped randomly as creatine (5g/day) or the placeb group (5g/day maltodextrin). Maximal strength (1-RM) and anaerobic performance (Wingate Anaerobic Test) were measured at baseline and post-intervention level. Paired t-tests were used in comparing within group and independent t-tests used in comparing between groups in reference to statistical analysis. Results: A marked improvement was seen in the strength of 1-RM of creatine (p<0.01) and peak power output of the Wingate test (p<0.05). The placebo group did not show any significant changes in either measure ( p>0.05). Conclusion: Creatine supplementation has a great effect as it improves the muscular strength and anaerobic performance of trained athletes which indicates that creatine supplement is a very effective ergogenic aid. These results justify the use of creatine in training sessions especially those involved with maximum efforts in brief intermittent activities.
