Purpose: To examine the net oxygen cost, oxygen kinetics, and kinematics of level and
uphill running in elite ultratrail runners. Methods: Twelve top-level ultradistance trail runners
performed two 5-min stages of treadmill running (level, 0%, men 15 km· h− 1, women 13 km·
h− 1; uphill, 12%, men 10 km· h− 1, women 9 km· h− 1). Gas exchanges were measured to
obtain the net oxygen cost and assess oxygen kinetics. In addition, running kinematics were
recorded with inertial measurement unit motion sensors on the wrist, head, belt, and foot …
