Intra- and inter-observer reliability in selection of the heart rate deflection point during incremental exercise: comparison to a computer-generated deflection point.

Abstract

This study was designed to 1) determine the relative frequency of occurrence of a heart rate deflection point (HRDP), when compared to a linear relationship, during progressive exercise, 2) measure the reproducibility of a visual assessment of a heart rate deflection point (HRDP), both within and between observers 3) compare visual and computer-assessed… (More)
