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.
