Caffeine Increases Anaerobic Work Capacity

February 28, 2012

Caffeine is a popular pre-workout energy and alertness booster for all types of athletes. There have been many studies measuring the effects active adults can expect from performance beverages containing caffeine, and a new one published in the International Sportmed Journal found a 23% increase in anaerobic work capacity.

Researchers had 8 men in their mid-20s ride a stationary bike to exhaustion at 80%, 90%, 100% and 110% of their peak power output. Subjects who has 6 mg of caffeine per kg of body weight (about 400 mg for a 150 pound guy) were able to ride further to exhaustion in the 100% and 110% trials when compared to subjects who got a placebo. The caffeinated cyclists also exhibited significantly improved anaerobic work capacity. If you get your caffeine from green tea, check out today's Breaking News post at optimumnutrition.com
