Abstract

The purpose of this study was to compare the ventilation-carbon dioxide production slope (VE-VCO₂ Slope) of a field walking test, comprising of a six minute walk test (6M) and self-paced walking (SP), with the exercise capacity or VE-VCO₂ Slope obtained by cardiopulmonary exercise testing (CPX). Expiration gas was measured during exercise loading in 25 healthy university students. The VE-VCO ₂ Slopes obtained by 6M and SP were significantly lower than the VE-VCO₂ Slope for CPX (p<0.04, p<0.0001). The 6M VE-VCO₂ Slope showed a significant negative correlation to the CPX VE-VCO₂ Slope (r=-0.41, p<0.02). Consequently, these results revealed the clinical usefulness of the 6M VE-VCO₂ Slope as an evaluation tool since it allows an estimation to be made for the CPX VE-VCO₂ Slope.
