KINESIOLOGY
PURPOSE OF STUDYING CLINICAL KINESIOLOGY
The purpose of studying clinical kinesiology is to understand the forces acting on the human body and to manipulate these forces in treatment procedures so that human performance may be improved and further injury may be prevented 了解动作

THREE ELEMENTS
the first;
identifies the sequence of activities performed from the start to the completion of the activity the second; presents a description of the joint movements throughout the activity the third;
了解作用在人体的力量 优化运动效能

REFERENCE
Cardinal planes of motion
Planes of Motion
Transverse Plane Frontal Plane (YZ plane) (XY plane)
Sagittal Plane (XZ plane)
WHAT KIND OF KINEMATIC CHAIN IS PERFORMED AS
chin-up (引體向上)?
one-legged squatting?
BASIC ARTHROKINEMATIC JOINT MOTIONS
(1) rolling or rocking,
(2) sliding or gliding, (3) spinning
Rolling
Developmental direction： nonsegmental ---segmental Supine to prone more individual variation more difficult than prone to supine
SUPINE TO PRONE ( ROLL TO THE RIGHT)
open kinematic chain motion 开链运动 • the joint motion with the distal segment moves free in space, e.g. raising lower leg or throwing a ball closed kinematic chain motion 闭链运动 • the joint motion with the distal segment is fixed, e.g. standing up or squatting down
使用動作量測分析系統的目 的
了解人體動作，肢幹間的相關性
• 運動學，動力學參數 設計、提升與評估人體運動、手工具、運動器材與醫療輔具等的功 能與成效
