The acute effects of a multi-ingredient pre-workout supplement on resting energy expenditure and exercise performance in recreationally active females.

What Was Tested

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

The purpose of this study was to examine the acute effects of multi-ingredient pre-workout supplement (MIPS) ingestion on resting metabolism and exercise performance in recreationally-active females.

Separate repeated measures analysis of variance (ANOVA) were used to assess differences in REE, cardiovascular responses, and subjective markers between conditions.

Why It Was Studied

Unfortunately, there is a tremendous lack of research being done regarding female athletes and the use of sport supplements.

Who Took Part

PubMed indexes the participants as young adults, women only.

Subjects completed baseline, and two experimental testing sessions in a cross-over design fashion.

Experimental testing included assessment of resting energy expenditure (REE), heart rate, and blood pressure following the ingestion of a MIPS or placebo.

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.

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

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

Each person switched between Copper (Supplement) and the comparison at some point, usually with a gap in between.

Fifteen recreationally-active females participated in a randomized, double-blind, placebo controlled study.

Subjective measurements of energy, focus, and fatigue were also assessed using a 5-point Likert scale.

Performance data were analyzed using paired Student's T-tests.

What Was Measured

PubMed files the paper under topics including Athletes, Basal Metabolism, Blood Pressure, Dietary Supplements, Exercise, Heart Rate and Sports Nutritional Physiological Phenomena.

The authors tagged it with the keywords Ergogenic aid, Fatigue, Muscular endurance and Thermogenic.
