M1 locate the bones, joints, movement types and muscles used during a range of sporting activities
Example one – a cricket throw
Throwing any type of ball overarm comes in two stages, the preparatory stage and the throwing stage. In the preparatory phase there are two joints involved and these are the shoulder and elbow. The shoulder has two articulating bones – the humerus and the scapula. The action is horizontal hyperextension. The agonist muscle are the posterior deltoids and the latissimus dorsi. The articulating bones in the elbow are the humerus and the ulna. The action is extension and the agonist muscle is the triceps brachii. The joints and articulating bones involved in the throwing phase are the same as the preparatory phase. The action in the throwing phase in the shoulder is horizontal flexion and the agonist muscles are the anterior deltoids and the pectoralis major. The action in the elbow is flexion and the agonist muscle is the biceps brachii.
Example two – kicking a football …show more content…
Kicking a football two parts, the preparatory stage and the kicking phase. The joints involved in both the preparatory stage and the kicking phase are the hip knee and the ankle. The action used in the hip is extension and hyperextension and the agonist muscle is the gluteal muscles. The action in the knee is flexion and the agonist muscles are the hamstrings. The action in the ankle is the plantar flexion and the agonist muscle is the gastrocnemius. During the kicking stage the action is the hip is flexion and the agonist muscle is the iliopsoas. The action in the knee is extension and the agonist muscle is the quadriceps. The action in the ankle is plantar flexion and the agonist muscle is the
