Dietary supplements for exercise and athletic performance
Creatine is one of the few supplements on the market, with a whole bevy of studies supporting its effects on exercise performance and muscle growth. Supplement makers are now competing to have their product included in a growing number of research studies and the FDA is preparing to approve new products. The latest supplement study, published in the American Journal of Clinical Nutrition on Tuesday, was an enormous surprise: creatine helped increase high intensity exercise performance by up to 30 percent in men after 6 weeks of supplementation. "Our study represents a major breakthrough because it's the first report in which creatine supplementation resulted in an improvement in elite running performance, and it was done at a large, rigorous, well-controlled laboratory testing facility in San Diego," study researcher and lead investigator John Berardi said, for performance dietary exercise and athletic supplements. It's unclear if this boost in performance was due to the extra dose of creatine, the result of a better workout regimen and/or the fact that men who took the creatine supplement reported greater muscle hypertrophy than men who did not. However, the researchers believe that these results are probably driven by the increase in strength produced by the creatine – which has been shown to increase muscle protein synthesis – as well as by the improvement in mental focus, memory and concentration during the exercise protocol, hitachi uae. While creatine supplementation may help boost performance for some, it's not necessarily the most effective approach for everyone. This study is small, relatively low volume, not placebo-controlled, and the results are likely to be biased either way since the test subjects didn't take any vitamins or minerals to improve performance or the placebo group consumed no creatine. If you do decide to take creatine, don't be alarmed if your results fall short of expectations – it's a natural supplement that works, dietary supplements for exercise and athletic performance.
