A Caffeine Fueled 15 KM Run

A Caffeine Fueled 15 KM Run Caffeine is arguably the world's most popular stimulant, and has been shown to enhance both endurance and strength performance. A study published in the journal Medicine and Science in Sports and Exercise looks at caffeine's effect on inflammation and oxidative stress after a 15 kilometer (9.3 mile) run.

Before undertaking this endurance competition, subjects received either 6 mg of caffeine per kg of body weight (420 mg for a 155 pound subject) or a placebo. Blood samples were taken before, immediately following and 2 hours after the 15 KM time trial. Caffeine elevated blood levels of adrenalin, glucose and lactate after exercise, and also contributed to higher levels of oxidative stress.

True Strength Moment: Researchers didn't record finish times for the 15 KM event, but it's safe to assume that caffeine helped runners cross the finish line faster. The question becomes, did caffeine elevated blood markers of inflammation and oxidative stress, or did the increase in exercise performance play a role?
