The effects of pace variation on the cost of running in trained runners

Abstract

This study was designed to evaluate the effects of pace variation on the cost of running (CR) in trained runners. Twenty runners (12 males and 8 females) completed a VO2max test to determine aerobic capacity and ventilatory threshold (VT). Subjects then ran four, 6-minute intervals on the treadmill with 2 minutes of walking in between each interval.
