Abstract
Creatine (Cr) supplementation has yielded inconsistent results when applied to competitive swimming. To further define the role of Cr, we tested the hypothesis that a Cr supplementation group of Division III swimmers would demonstrate enhanced performance when compared with placebo. In order to test this hypothesis, 8 male and 7 female collegiate Division III swimmers were assigned in a random, double-blind manner into either a Cr supplementation group (0.3 g Cr-kg− 1 body mass) or a placebo group. Loading was maintained for 5 days followed by a 9-day period where Cr-supplemented subjects consumed 2.25 g Cr regardless of body weight. A 50-and 100-yd sprint was performed prior to and following the supplementation regimens. The Cr supplementation group decreased their finish times in both the 50-and 100-yd sprints. Support of the hypothesis suggests that Cr supplementation for swimming events is effective for singular effort sprints of 50 and 100 yd in Division III athletes.
