Creatine-electrolyte supplementation improves repeated sprint cycling performance: A double blind randomized control study.
Study Goal
The researchers aimed to determine whether a six-week creatine-electrolyte (CE) supplementation intervention improved overall and repeated peak and mean power output during repeated cycling sprints with 2-minute recovery periods.
Results Summary
The study found a 4% increase in overall peak power and concluded that CE supplementation improves overall and repeated short-duration sprint cycling performance when sprints are interspersed with adequate recovery periods.

BACKGROUND: Creatine supplementation is recommended as an ergogenic aid to improve repeated sprint cycling performance. Furthermore, creatine uptake is increased in the presence of electrolytes. Prior research examining the effect of a creatine-electrolyte (CE) supplement on repeated sprint cycling performance, however, did not show post-supplementation improvement. The purpose of this double blind randomized control study was to investigate the effect of a six-week CE supplementation intervention on overall and repeated peak and mean power output during repeated cycling sprints with recovery periods of 2 min between sprints. METHODS: Peak and mean power generated by 23 male recreational cyclists (CE group: RESULTS: A supplement-time interaction showed a 4% increase in overall peak power (pre: 734 ± 75 W; post: 765 ± 71 W; CONCLUSION: A CE supplement improves overall and repeated short duration sprint cycling performance when sprints are interspersed with adequate recovery periods.
