Effects of Multi-Ingredient Pre-Workout Supplement and Caffeine on Bench Press Performance: A Single-Blind Cross-Over Study.

What Was Tested

The paper reports a study of Copper (Supplement), published as a clinical trial.

A group of fifteen resistance-trained males, weighing 83.92 ± 8.95 kg and having an average of 5.6 ± 3.38 years of training experience, tested their bench press 10 repetition maximum (79.01 ± 12.13).

Who Took Part

PubMed tags the participants as men only.

In a cross-over manner, they participated in two sessions where they were blinded to the order of supplementation they were given: either a MIPS including caffeine or caffeine alone.

How the Study Was Run

In design terms this was a double-blind, single-blind and crossover study.

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

Only one side, usually the participants, was kept unaware of whether Copper (Supplement) was given.

In the crossover set-up each of the participants took both Copper (Supplement) and the comparison in turn, acting as their own control.
