Subjects | Supplementation Protocol | Test Protocol | Results | |
---|---|---|---|---|
Burke et al. 1996 | 32 (18 Male; 14 Female) 17-25 yrs National level swimmers |
5g Creatine monohydrate + 2g sucrose OR 5g polyglucose + 2g sucrose 4 x per day, 5 Days Randomised, double blinded |
Cycle ergometer 2 x 10sec maximal effort sprints 10mins rest between sprints |
No differences in work performed, peak power, or time to peak power between trials or between groups. |
Grindstaff et al. 1997 | 18 (7 Male; 11 Female)~ 15 yrs Regionally / nationally competitive amateur swimmers | 21g Creatine monohydrate + 4.2g maltodextrin OR 25.2g maltodextrin 9 Days Randomised, double blinded |
Swim bench ergometer 3x20sec maximal effort sprints 60sec rest between sprints | Greater overall changes in work performed by the creatine group than the placebo group Significant improvements in work performed during sprint 1 only (7.8%) for the creatine group only. No differences in peak power output between trials or between groups. |
Dawson et al. 2002 | 20 (10 Male; 10 Female) ~ 16 yrs Competitive swimmers |
Acute loading period: 5g creatine monohydrate + 1g glucose polymer OR 6g glucose polymer 4 x per day, 5 days Maintenance period: 5g creatine monohydrate OR 5g glucose polymer 1 x per day, 22 days Randomised, single blinded |
Swim bench ergometer 2x30sec maximal effort sprints 10mins rest between sprints | Significantly greater increases in total work performed in the creatine group (7.5%) compared to the placebo group (2.0%) |
