The key requirement of a successful golf swing is an accurate impact. The body and arm motions during the backward and forward swings must be executed in such a way that an accurate impact is secured. Novice golfers experience difficulties in coordinating the arm and body motions due to the complexity of the mobility system formed by the trunk and arms. Differentiation of the abnormal swings causing inaccurate impact from normal swings through in-depth trunk motion analysis is thus of importance. The purpose of this study was to provide a biomechanical profile of the normal golf swing in terms of trunk motion ranges and patterns with the aim of establishing baseline data for comparative studies.
