 A
resent study showed caffeine supplementation had a significant positive impact on short
term running performance.Nine well-trained males performed a preliminary assessment
and, at least 4 days later, a supramaximal run to exhaustion. Their VO2max values were
determined, and the maximal accumulated oxygen deficit (MAOD) test at an exercise
intensity equivalent to 125% VO2max was performed. Caffeine (5 mg per kilogram of
bodyweight) or placebo was administered 1 hour prior to the MAOD in a double-blind,
randomized cross-over study. In comparison to the placebo condition, subjects in the
caffeine condition developed a significantly greater MAOD and increased their run time to
exhaustion.
This study concluded that caffeine supplementation can be an effective ergogenic aid
for short-term, supramaximal running performance and can increase MAOD.
