Bliss, M. V., Bellar, D., Kamimori, G. H., Glickman, E. L., Barkley, J. E., Ryan, E. J., & Bellar, A. (2008). The effect of caffeine supplementation on performance in the standing shot put throw. ACSM 55th Annual Meeting Indianapolis, Presentation Number, 2036.

This investigation determined if caffeine had ergogenic effects on performance in the standing shot put event. Male (N = 4) and female (N = 5) small-college shot putters received either a piece of gum designed to deliver 100 mg of caffeine in a buccal manner, or a placebo gum. The gum was chewed for five minutes then discarded. Ss then completed a series of five warm-up throws, followed by six attempts for distance with a shot put (16lbs for males, 4kg for females).

A significant difference (treatment x throw) was found indicating that the caffeine treatment produced better performance improvements over the course of the six attempts.

Implication. Low-dose caffeine increased the performance of standing shot putters over the course of six attempts.
