A creatine-protein-carbohydrate supplement enhances responses to resistance training.

What Was Tested

The paper reports a study of Creatine, published as a randomized controlled trial.

Studies attributing gains in strength and lean body mass (LBM) to creatine monohydrate (CrM) during resistance exercise (RE) training have not assessed these changes alongside cellular and subcellular adaptations.

Additionally, CrM-treated groups have seldom been compared with a group receiving a placebo similar in nitrogen and energy.

The purpose of this study was to examine the effects of a CrM-containing protein-carbohydrate (PRO-CHO) supplement in comparison with a supplement containing a similar amount of nitrogen and energy on body composition, muscle strength, fiber-specific hypertrophy, and contractile protein accrual during RE training.

Who Took Part

PubMed tags the participants as men only.

How the Study Was Run

In design terms this was a randomized, double-blind and placebo-controlled study.

Because people in this Creatine study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

Blinding on both sides kept the participants and researchers unaware of who received Creatine.

The comparison arm used a placebo, so changes seen with Creatine could be set against what happens without it.

What Was Measured

PubMed files the paper under topics including Body Composition, Creatine, Dietary Carbohydrates, Dietary Proteins, Dietary Supplements, Victoria and Weight Lifting.
