Dietary supplementation (SUP) has become a significant part of athletic tra
ining. Studies indicate that creatine (Cr) can enhance short-duration, high
-intensity activities. This study examined the effect of 21 days of low dos
e Cr SUP (similar to 7.7 g/day) and resistance training on force output, po
wer output, duration of mean peak power output, and total work performed un
til fatigue. A double-blind protocol was used, where an individual, who was
not part of any other aspect of the study, randomly assigned subjects to c
reatine and placebo groups. Forty-one male university athletes were randoml
y assigned to either Cr (n = 20) or placebo (n = 21) SUP. On the first and
last day of the study, subjects were required to perform concentric bench p
ress movements until exhaustion on an isokinetic dynamometer. The dynamomet
er was hard-wired to a personal computer, which provided force, velocity, a
nd duration measures. Force and power output until fatigue, were used to de
termine total work, force-time, and power-time relationships. ANOVA results
revealed that the Cr subjects performed more total work until fatigue, exp
erienced significantly greater improvements in peak force and peak power, a
nd maintained elevated mean peak power for a longer period of time. These r
esults indicate that Cr SUP can significantly improve factors associated wi
th short-duration, high-intensity activity.
