Unit 1: Principles of Anatomy and physiology in Sport Joint movements Kevin Browne

Aims of the lesson In relation to the assignment this lesson will focus on P2 P2 Describe the different classifications of joints Identify and describe joint movements in their specific terms Describe at least six different terms of movement and where they occur in the body

General movements General movement apply to more than one joint in the body These type of movement have specific anatomical names For example flexion, extension List as many other anatomical names that you may know for movement( you will have covered these in level 2 sport or GCSE PE.

Decreasing the angle of a joint, or bending a limb Bending the knee Movement type Description Example Flexion Decreasing the angle of a joint, or bending a limb Bending the knee Extension Increasing the angle of a joint, or straightening a limb Straightening the knee Abduction Taking a limb away from the mid-line of the body Lifting the arms from the side of body Adduction Taking a limb towards the mid-line of the body Lowering the arms towards the side of the body Rotation When a limb rotates about it's own axis Looking over your shoulder This can be done as a matching task/ or fill in the blanks

Movement type Description Example Circumduction When one end of the limb describes a circle Doing the butterfly stroke in swimming Supination Rotation of the forearm causing the palm of the hand to face up Turning your hands from facing down, to turning up Pronation Rotation of the forearm causing the palm of the hand to face down Turning your hands from facing up to facing down Eversion At the ankle when the sole of the foot is turned outwards Kicking a football with the instep Inversion At the ankle when the sole of the foot is turned inwards When you twist your ankle it is excessive inversion

Movement type Description Example Dorsi flexion At the ankle joint when the toes are pulled upwards towards the shin When you do a calf stretch Plantar flexion At the ankle when the toes are pointed downwards When you stand on tip toes Depression Downward movement of the shoulder girdle Pushing the shoulder blades down Elevation Upward movement of the shoulder girdle Shrugging the shoulders Horizontal flexion & extension Occurs when the arm (at shoulder height) moves across the body, and back out to the side. Bringing the arm across and then away from the body

Movement type Description Example Hyper extension Excessive extension beyond straight A crab position in gymnastics Lateral flexion Bending to the side Tilting of the head Protraction The shoulders are drawn forwards Rounding of the shoulders Retraction The shoulders are drawn backwards Opening out the chest
