CREATINE AND WEIGHT LIFTING Introduction Creati

Substantial research has examined the effects of creatine as it relates to bodybuilding or weightlifting. In an effort to bring more clarity to the findings of this research, Dempsey, Mazzone, and Meur (2002) investigated whether oral creatine increased maximal strength and power by conducting a meta analysis of research studies that had investigated creatine in relation to bodybuilding. Sixteen studies were identified for inclusion in the conducted meta analysis. Outcome measures in these studies included Pre-supplementation and post-supplementation change in maximal weight lifted, cycle ergometry sprint peak power, and isokinetic dynamometer peak torque.

In almost all studies included in the meta-analysis, findings were said to show that the maximum weight lifted was significantly greater after creatine, greater for bench press and squats in particular. Based on a review of all studies, it was concluded that oral creatine supplementation, when combined with resistance training, increases maximal weight lifted in young men. However, the authors noted that they

upplements among all levels of athletes, clinicians cannot avoid questions about the effectiveness and safety of creatine supplementation. This meta-analysis demonstrated that oral creatine does improve performance during maximal resistance exercises in young men. However, we found no benefit for outcomes other than maximal weight lifted, suggesting that creatine may not improve actual performance in more complex movements requiring strength, speed, and coordination of multiple muscle groups. Studies investigating the effect of creatine in actual athletic performance are lacking. Several important questions remain to be answered about creatine. What are the effects for women and older individuals? Is resistance training necessary to see strength performance improvement? Are these improvements in strength accompanied by improved athletic performance? How long do the effects of creatine remain after discontinuing supplementation? Most importantly, what is the long-term safety profile of creatine? Without further research to answer these questions, we cannot support the use of creatine supplementation for performance enhancement despite evidence for a positive impact on some components of strength.
