The role of stride frequency for walk-to-run transition in humans

Abstract It remains unclear why humans spontaneously shift from walking to running at a certain point during locomotion at gradually increasing velocity. We show that a calculated walk-to-run transition stride frequency (70.6 ± 3.2 strides min−1) agrees with a transition stride frequency (70.8 ± 3.1...
