The Effect of a Multi-ingredient Supplement on Resistance Training-induced Adaptations.

What Was Tested

This randomized controlled trial looks at Copper (Supplement).

The researchers aimed to determine the effect of a high-quality multi-ingredient nutritional supplement (SUPP) versus an isonitrogenous (lower protein quality), isoenergetic placebo (PL) on RET-induced gains in lean body mass (LBM), muscle thickness, and muscle cross-sectional area (CSA).

The researchers hypothesized that RET-induced gains in LBM and muscle CSA would be greater in SUPP versus PL.

Why It Was Studied

Resistance exercise training (RET) induces muscle hypertrophy that, when combined with co-temporal protein ingestion, is enhanced.

However, fewer studies have been conducted when RET is combined with multi-ingredient supplements.

Who Took Part

By PubMed's age tags, the people studied were young adults, both men and women.

How the Study Was Run

The design is described as randomized, double-blind and placebo-controlled.

Random assignment meant chance, not the researchers, decided who got Copper (Supplement) and who got the comparison, which limits bias.

As a double-blind Copper (Supplement) study, the assignments were hidden from both participants and investigators until the end.

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

What Was Measured

The subject headings attached to it are Adaptation, Physiological, Body Composition, Dietary Supplements, Muscle Strength, Muscle, Skeletal and Resistance Training.
