Types of joint movement in the movement Flashcards
Flexion
Bending a joint. This occurs when the angle of a joint decreases. For example, the elbow flexes when performing a bicep curl. The knee flexes in preparation for kicking a ball.
Extension
Straightening a joint. This occurs when the angle of a joint increases, for example the elbow when throwing a shot put. The take-off knee extends when a high-jumper takes off (the other knee is flexed).
Flexion
At the shoulder joint occurs when the humerus (upper arm) moves forwards from the rest of the body, which happens at the end of an underarm throw or bowl in rounders.
Abduction
Movement away from the mid-line of the body. This occurs at the hip and shoulder joints during a jumping jack movement.
Adduction
Movement towards the mid-line of the body. This occurs at the hip and shoulder, returning the arms and legs back to their original position from a jumping jack movement or when swimming breaststroke.
Circumduction
This is where the limb moves in a circle. This occurs at the shoulder joint during an overarm tennis serve or cricket bowl.
