Biomechanics

• The use of numbers when analysing human movement
• E.g. Six metreres, 3 seconds, 2 platers

• A description of quality without the use of numbers
• E.g. Good, poor, long

• Is the release of the ball taking place at the instant of full elbow extension?
• Is there excessive pronation taking place?

• Why is this shot putter not getting more distance?
• Is the movement being performed through an appropriate ROM?

General motion

• Involves a line that may be straight or curved, with all body parts moving in the same direction, at the same speed
• E.g. Sleeping passenger on an airplane

Rectilinear

Curvilinear

Rotation around a central imaginary line (axis of rotation)

• Involves translation and rotation simultaneously.
• E.g. a football

3 imaginary perpendicular lines that divide the body in half by mass

• The plane in which forward and backward movement of the body and body segments occur
• (left and right sides)
• e.g. Marching, bowling, cycling

• The plane in which lateral movements of the body and body segments occur
• (front and back)
• E.g. Sidestepping and cartwheels

The plane in which horizontal body and body segment movements occur when the body is in an erect standing position
