Document Summary
A combination of motion at several joints is called a movement pattern: e. g. , kicking, punching. These movement patterns are applied to a range of tasks and the timing of the joints, roms of the joints, trajectories of the segments can differ between people. When the movement pattern is employed for a well-defined activity or for a sport then we refer to it as a skill. The performance and outcome of a skill is more easily quantified than a movement pattern i. e. , kicking a field goal (skill) is harder to do than just kicking a football (movement pattern) Open skill: the motion and environment are unpredictable, i. e. defending in basketball. Closed skill: the motion and environment are predictable and under your control, i. e. basketball free throw. Open kinetic chain: the end of the moving chain of segments is free to move (translate and rotate) i. e. a baseball pitcher(cid:859)s ar(cid:373) More dof; 6 full dof, less stable.
