CREATINE & CAFFINE DON'T MIX
This study, hot off the presses, perhaps shows why creatine doesn't always produce positive results for everyone. A group of Belgian scientists examined 9 healthy male subjects (ages 20-23 years) who were physically active but not highly trained. Before and after six days of creatine (.5 g/kg per day), creatine plus caffeine (same dose of creatine plus 5 mg/kg per day of caffeine), and placebo treatment, they found that muscle ATP concentration was the same throughout the experiment. However, phosphocreatine levels increased significantly (4%-6% in both the creatine and creatine plus caffeine groups). Knee extension torque increased 10%-23% only in the creatine group. The creatine plus caffeine and placebo groups didn't exhibit increases in muscle torque. This study demonstrates that caffeine can negate the ergogenic effects of creatine.
