The Effect of a Multi-Ingredient Pre-Workout Supplement on Time to Fatigue in NCAA Division I Cross-Country Athletes.

What Was Tested

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

This investigation aimed to determine the effect of a multi-ingredient pre-workout supplement (MIPS) on heart rate (HR), perceived exertion (RPE), lactate concentration, and time to fatigue (TTF) during a running task to volitional exhaustion.

Why It Was Studied

Eleven NCAA Division I cross-country runners (20 ± 2 year; height: 171 ± 14 cm; weight: 63.5 ± 9.1 kg) participated in this randomized, double-blind, placebo-controlled cross-over study.

Who Took Part

The age groups tagged for this paper are teenagers, young adults and adults, both men and women.

How the Study Was Run

The researchers set it up as a randomized, double-blind, placebo-controlled and crossover study.

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

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

Some participants received a placebo instead of Copper (Supplement), giving a reference point.

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

The subject headings attached to it are Athletes, Beta vulgaris, Caffeine, Dietary Supplements, Lactic Acid, Muscle Fatigue and Performance-Enhancing Substances.

Author keywords: acute, endurance, ergogenic aid, multi-ingredient pre-workout supplement, running performance and sports nutrition.
