Montmorency cherry supplement does not affect aerobic exercise performance in healthy men.

What Was Tested

This observational study looks at Copper (Supplement).

Aim: To determine the effects of short-term Montmorency cherry (MC) supplementation upon exercise performance, total blood nitrate levels, muscle oxygenation, and slow-component [Formula: see text]O2 kinetics.

Near-Infrared Spectroscopy sensors were used to determine muscle oxygenation.

Why It Was Studied

Blood was collected one hour post-supplement consumption on day one, day six, and one hour post-exercise.

Results: All results are presented as mean ± SEM.

Who Took Part

PubMed tags the participants as men only.

How the Study Was Run

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

The participants were allocated by chance, so the Copper (Supplement) group and the comparison group should start out alike.

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

A placebo (an inactive look-alike) gave the Copper (Supplement) group a baseline to be compared against.

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
