Assessment of EPInfant scale for exercise intensity perceptual self-regulation in healthy children.

Introduction: The EPInfant scale has been validated for the perceptual estimation of physical exer tion in Chilean children, but its usefulness for self-regulation of exercise intensity is unknown. The objective of the study was to evaluate the criterion validity of the EPInfant scale to regulate and re produce exercise intensity in a sample of healthy children.

Subjects And Method: 15 children between the ages of eight and 12 were selected for an incremental exercise test (IET) and three perceptually regulated exercise tests (PRET) on a treadmill.
