Control of exercise intensity using treadmill and music

Abstract

This study examined the relationships among step rate while running (beats per minute; bpm), heart rate, and leg joint characteristics while running at various speeds. Kinematic gait analysis of 81 young people (40 males, 41 females) was performed on a treadmill. Three kinematic parameters (hip, knee, and ankle flection) and heart rate were measured when the subjects ran at speeds of 4, 6, 8, 10, and 12 km/h. The results showed that 1) the distance from the heel to the femoral head is positively correlated with the step rate independent of running speed, and 2) it is possible to devise a suitable training model for individual subjects by measuring the distance from the heel to the femoral head and referring to the relationship of step rate, heart rate, and treadmill speed.
