The purpose of this study was to compare the physiological and biomechanical differences between heel-toe running and the Pose technique. After 15 heel-toe runners (age: 22.5±5.8 years, wt: 65.5±13.5 kg) performed Bruce Protocol VO2max tests, gross efficiency was determined by a 20-minute run performed at 70% of each subject’s VO2max. Running mechanics at this speed were analyzed using Peak Motus; three strides with ground reaction force data were used. After 5 consecutive days (1.5 hours/day) of Pose technique training, the pretest procedures were repeated. Paired t-tests were used to compare pretest and posttest data. The Pose technique significantly decreased knee angles at foot-strike, maximum knee flexion during swing, and support time, while significantly increasing non-support time and peak anteroposterior propulsive force from heel-toe running (p<0.05). The Pose technique significantly decreased cardiovascular efficiency (p<0.05) compared to heel-toe running. The Pose technique may not improve running efficiency or mechanics.
