Anatomy: Study of body structure (from Greek 'to cut open').
Physiology: Study of how body functions.
Both necessary for understanding the human body.
Importance of Kinesiology
Applies knowledge of anatomy and physiology to understand and analyze movement.
Subdivisions of Kinesiology
Kinetics
Study of forces producing or resisting movement.
Example: Calculating needed force to move a box considering friction.
Kinematics
Study of movement without regard to forces involved.
Example: Analyzing the movement of a person doing a seated Russian twist.
Focus Areas:
Type of movement
Position of body or its segments
Direction of movement
Subdivisions of Kinematics
Osteokinematics
Root Word: "osteo" (bone).
Relates to movement produced by bones forming joints.
Arthrokinematics
Root Word: "arthro" (joint).
Refers to minute movements within and between joint surfaces.
Tools
Goniometer: Measures joint range of motion, used in kinematics to measure joint angles.
Summary
Understanding both structure and function is crucial in kinesiology.
Kinesiology integrates anatomy and physiology to apply knowledge to movement studies, exploring both kinetics and kinematics and their detailed subdivisions.
