The influence of the pre-delivery stride on subsequent fast bowling technique in elite male cricketers

Research in cricket fast bowling has primarily investigated technique from back foot contact onwards. This study aims to explore the effect of the pre-delivery stride (step pre-back foot contact) on technique characteristics previously linked with performance and injury risk. Six pre-delivery stride, and 16 performance or lumbar bone stress injury-related technique characteristics were determined for 29 elite male fast bowlers. Fifteen significant correlations were observed between the pre-delivery stride and the performance and injury-risk characteristics (<i>p</i> < 0.05). From a performance perspective, greater pre-delivery run-up velocity and lower take-off angles were associated with increased front leg plant angles at front foot contact and knee flexion at ball release. From an injury perspective, greater anterior pelvic tilt at take-off, jump height, and landing vertical velocity at back foot contact were associated with more flexed rear leg kinematics at back foot contact and anterior pelvic tilt at front foot contact. These findings suggest individual-specific pre-delivery stride run-up velocities and take-off angles exists to synchronously optimise technique to enhance performance and reduce injury risk. This knowledge is essential for enhancing the coaching and rehabilitation of fast bowlers, supporting coaches to account for the effect of the pre-delivery stride on subsequent fast bowling technique.
