The Link System B.1. (Motion, plane, axis, type of joint, prime mover) Anatomical Position Upright all joints extended palms facing forward Planes of Motion Sagittal - divides into left and right (cardinal-sagittal goes thru midline) Frontal - front and back Transverse - upper and lower Axis of Rotation (caused by intersection of two planes) Test Item ** Mediolateral - frontal and transverse planes (runs side to side) Anteroposterior - transverse and sagittal planes (runs front and back) Inferiorsuperior - frontal and sagittal planes (runs up and down) Cover movements in/around the planes/axis (overhead) B.2. Factors contributing to success Alterable: Motivation, nutrition, interest, opportunity for practice Unalterable: Anthropometrics (Kinanthropometrics = having to do with sport) Some sports offer distinct advantages height increasing in those sports that benifits remaining constant in others - Height and weight Ponderal Index = 103 times(cube root WT/HT) Light athletes around 23.0 Larger athletes near 25.0 - Somatotype ectomorph - tall & thin endomorph - short and fat mesomorph - stout and muscular - Other Arm, Leg, & trunk lengths ** Important that these cannot be changed, and at the level most people compete at, are not a critical factor.
