아이스하키 리스트 샷(Wrist shot) 동작의 상지 협응 형태

Abstract

The purpose of this study was to investigate the relations between the segments of the body and to qualitatively analyze coordination pattern of joints and segments during Wrist Shot movement in Ice Hockey, By the utilization the three dimensional anatomical angle cinematography, the angles of individual joint and segment according to Wrist shot in ice hockey. The subjects of this study were five professional ice hockey players. The reflective makers were attached on anatomical boundary line of body. For the movement analysis three dimensional cinematographical method(APAS) was used and for the calculation of the kinematic variables a self developed program was used with the LabVIEW 6.1 graphical programming(Johnson, 1999) program. By using Eular`s equations the three dimensional anatomical Cardan angles of the joint and ice hockey stick were defined. The used coordination variables were angle vs. angle plots. The three dimensional anatomical angular displacement and coordination pattern of trunk and Upper limb(shoulder-elbow-wrist linked system) showed important role in Wrist shot. the most important role is coordination pattern of trunk and shoulder joint and is followed by shoulder and elbow joints, in addition the movement of elbow/wrist joints showed least to the Wrist shot. this study result showed flexion-extension, adduction-abduction and internal-external rotation of trunk are important role of power and shooting direction coordination of upper Limb pattern of Wrist Shot movement in Ice Hockey.
