Effects of Theacrine as a Pre-Workout Supplement.

What Was Tested

This randomized controlled trial looks at Copper (Supplement).

However, the studies on this supplement are scarce.

Therefore, this study is a randomized, controlled trial that aimed to verify the effects of theacrine supplementation over physical performance in young male athletes, by applying a battery of physical tests.

Who Took Part

PubMed tags the participants as men only.

Twenty-two male amateur flag-football athletes were recruited.

How the Study Was Run

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

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

Neither the participants nor the staff measuring them knew who was on Copper (Supplement), so expectations could not easily colour the readings.

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

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

What Was Measured

Therefore, this study is a randomized, controlled trial that aimed to verify the effects of theacrine supplementation over physical performance in young male athletes, by applying a battery of physical tests.

The subject headings attached to it are Dietary Supplements, Caffeine and Uric Acid.

The authors tagged it with the keywords alkaloids, dietary supplementation and physical education and training.
