Cocoa-flavanols enhance moderate-intensity pulmonary [Formula: see text] kinetics but not exercise tolerance in sedentary middle-aged adults.

ABSTRACT:

Introduction

Cocoa flavanols (CF) may exert health benefits through their potent vasodilatory effects, which are perpetuated by elevations in nitric oxide (NO) bioavailability. These vasodilatory effects may contribute to improved delivery of blood and oxygen (O₂) to exercising muscle.

Purpose

Therefore, the objective of this study was to examine how CF supplementation impacts pulmonary O₂ uptake ([Formula: see text]) kinetics and exercise tolerance in sedentary middle-aged adults.

Methods

We employed a double-blind cross-over, placebo-controlled design whereby 17 participants (11 male, 6 female; mean ± SD, 45 ± 6 years) randomly received either 7 days of daily CF (400 mg) or placebo (PL) supplementation. On day 7, participants completed a series
