M1 locate the bones, joints, movement types and muscles used during a range of sporting activities:
Example 1 – Andy Murray tennis serve.
The Andy Murray serve begins with him lining up at a 45 degree angle to the baseline. His legs are a little more than body width apart with the left foot about 30 degrees off the line. This stance means that he will be using a big turn of the whole body to assist in providing some of the power to his serve. His arms are extended out in front. His left hand holds the ball and supports the racket at the shoulder of the frame. The right hand grips the racket in a continental grip.
The actual motion of the Andy Murray serve begins as he tosses the ball. He loads up his weight on the back foot and his tossing …show more content…
In the first stage the leg muscles are used to gain power for the second phase. The racket is then thrown back and so is the body weight, this involves the abdominals. In the next phase the body is then lifted off the ground and the shoulder muscles and the latissimus dorsi is then used, it adducts, extends and rotates the arm to follow through and hit the ball. The triceps are then used and contract to get full power. The tennis player will then jump and the latissimus dorsi will come in use again. Then the racket will come down over the ball and hit it, the arm will now have done a full rotation. The serve uses a combination of horizontal and vertical movements. Horizontal abduction and external rotation occur during the backswing, with scapular retraction and depression into the loading phase. The leg muscles are
Example 2 – cricket throw.
Throwing a ball comprises of two phases, the preparatory phase and the throwing phase. Most actions are rotational in the transverse plane and longitudinal axis and the two joints primarily involved are the elbow and shoulder. The elbow is a hinge joint formed by the humerus and ulna. The shoulder is a ball and socket joint formed between the humerus and the scapula.
The joints that are involved in a throw are the shoulder and the elbow. The bones in the shoulder are the humerus and the scapula. The bones that are used in the elbow are the humerus and the ulna. In the shoulder the action is horizontal hyperextension and in the elbow it is extension. The muscles that are involved are the posterior deltoids and latissimus dorsi, and triceps
