Abstract
Position Statement: The position of The Society regarding caffeine supplementation and sport performance is summarized
by the following seven points: 1.) Caffeine is effective for enhancing sport performance in trained athletes
when consumed in low-to-moderate dosages (~3-6 mg/kg) and overall does not result in further enhancement in
performance when consumed in higher dosages (≥ 9 mg/kg). 2.) Caffeine exerts a greater ergogenic effect when
consumed in an anhydrous state as compared to coffee. 3.) It has been shown that caffeine can enhance vigilance
during bouts of extended exhaustive exercise, as well as periods of sustained sleep deprivation. 4.) Caffeine is ergogenic
for sustained maximal endurance exercise, and has been shown to be highly effective for time-trial performance.
5.) Caffeine supplementation is beneficial for high-intensity exercise, including team sports such as soccer
and rugby, both of which are categorized by intermittent activity within a period of prolonged duration. 6.) The literature
is equivocal when considering the effects of caffeine supplementation on strength-power performance, and
additional research in this area is warranted. 7.) The scientific literature does not support caffeine-induced diuresis
during exercise, or any harmful change in fluid balance that would negatively affect performance.
