Caffeine Effects Oxidative Stress

Caffeine Effects Oxidative Stress Caffeine is the world's most popular pick-me-up. It's also a favorite of athletes who harness its potential to improve both aerobic and anaerobic performance. A study published in the journal Medicine and Science in Sports and Exercise suggests pre-workout caffeine can also increase the inflammation and oxidative stress you'd experience as a result of intense training.

Thirty-three runners competed in a 15 km event supplemented with 6 mg of caffeine per kg of body weight or a placebo. Blood samples taken immediately after the race and 2 hours later showed higher increases of adrenaline, glucose and lactate in the caffeinated runners. A greater degree of post-exercise inflammation and oxidative stress was also recorded.

True Strength Moment: Since 6 mg per kg of body weight works out to 462 mg of caffeine for a 170 pound runner, it's safe to assume that caffeine outperformed the placebo group. Was it the extra effort or the caffeine that elevated the oxidative and inflammatory response to exercise? If your pre-workout formula includes anti-oxidant support, there's a chance it might help balance the effect.
