The hockey stride has been described by bio-mechanists as biphasic in nature consisting of alternating periods of single leg and double leg support.  The single support phase corresponds to a period of glide, while the double support phase corresponds to the onset and preparation of propulsion (Marino, 1977).  Both stride rate and stride length have been investigated as a means of measuring/separating the skating velocities of high caliber and low caliber skaters. The purpose of this short blog is to investigate the research in order to answer the question:  which is more important, stride length, or stride rate?

Skating can be described as a bi-phasic activity involving both a support phase and a swing phase  (Garrett & Kirkendall, 2000; Marino, 1977; Upjohn, Turcotte, Pearsall, & Loh, 2008).  The support phase may be further subdivided into both single leg support, corresponding to glide, and double support corresponding to push off.   Propulsion occurs during the first half of single leg support and commences during double leg support as the hip is abducted and externally rotated and the knee is extended (Garrett & Kirkendall, 2000; Marino, 1977).  Skating is a skill, and the differences between elite and non-elite skaters have been investigated by a number of researchers  (Budarick et al., 2018; McPherson, Wrigley, & Montelpare, 2004; Shell et al., 2017; Upjohn et al., 2008)
