The purpose of this study was to analyse the joint angular impulse-effect on knee joint extension-flexion angle on a sample of bowlers, determining whether front-leg technique is predominantly dependent on local joint torques or non-local cumulative effects generated elsewhere in the kinetic link chain. Elite young fast bowlers (n=13) were recruited for a motion analysis of their bowling actions in a biomechanics laboratory. Their fast bowling actions were classified according to front-leg technique and their changes in front knee extension-flexion angle related to corresponding joint angular impulse motion-effects. The majority of bowlers (61.5%) bowled with a bent-leg lever. Only 3.4% of knee extension-flexion periods were subject to an active angular impulse motion-effect. This result implies that knee extension-flexion angle in fast bowlers is also dependent on motions occurring away from knee joint, remotely located in the kinetic link chain.
