Study Notes
Body Movement
- Comprises both linear and rotary motions, exemplified by walking.
- Focuses on analyzing factors affecting physical activity in daily life, work, recreation, and sports.
Mechanics
- Refers to the scientific study of forces acting upon matter.
- Divisions include:
- Statics: Analyzes bodies at rest or in uniform motion.
- Dynamics: Studies bodies in acceleration or deceleration.
Biomechanics
- Integration of biology and mechanics.
- Divisions include:
- Kinematics: Examines the motion of bodies in space.
- Kinetics: Focuses on the forces that cause motion.
Kinematics
- Utilizes a rectangular coordinate system to describe body motion in space.
- Central points of the Sagittal Plane differ for various body parts:
- Hand: 3rd digit.
- Foot: 2nd toe.
Determinants of Motion
- Defined as the displacement of a body segment from one location to another.
- Variables affecting motion include:
- Type
- Location
- Magnitude
- Direction
- Rate (speed of motion change)
Types of Motion
- Translatory motion involves the movement of a rigid segment along a straight path.
- Rotary motion revolves around an axis.
Magnitude of Motion
- Distance measures how far a force moves a body.
- Linear displacement is measured in straight lines.
- Rotary motion is measured in degrees or radians.
Goniometry
- Involves the application of a coordinate system to measure angles and ranges of motion.
