School Hammer Throwing

The hammer throw is one of the three kinds in throwing and an event in track and field . It is described as a loopy upside-down throw and apparently a hard one to master

There are four basic steps in throwing a hammer : the winds , transition to the turn , turn , and the release . Each step or phase involves shifting , bending , rotating and balancing and one must have well coordinated muscles movement . Attention must be given to the

five bio-motor elements : skill , speed , strength , suppleness , and stamina

The winds give special attention with the grip or holding of the hammer . The hammer must be gripped by the left hand (for right handed while the right hand is on top and the ball on the right side of the body . It involves swinging of the hammer around the head at the same time bending of the legs . This phase mostly involves the use of neck shoulder , arm and hand muscles when swinging and rotating the hammer and the lower body muscles when maintaining balance . The major head and neck muscle is the sternocleidomastoid . Trapezius muscle pulls the head and shoulder backwards and the deltoid muscles enable the movement of the shoulder and the upper arm . Pectoralis major muscle of the chest is also involve . Arm muscles like the biceps and triceps bend and straighten the arms . Involve are the extensors : extensor carpi radialis brevis and longus , extensor carpi ulnaris , extensor digiti minimi extensor digitorum , extensor indicis , abductor pollicis longus , the extensor pollicis brevis , triceps brachii , and anconeus the flexors flexor carpi radialis , flexor digitorum profundus , flexor digitorum superficialis , flexor pollicis longus , palmaris longus , and flexor retinaculum and the rotators : pronator quadratus , pronator teres supinator brevis , and supinator longus (brachioradialis muscle . The major leg muscles are the rectus and biceps femoris which are responsible for raising and strengthening the legs . The tibialis anterior and gastroenemius are responsible for the bending of feet and toes

Involve joints are the hinge joints of knees and elbows , pivot joints of the head and the ball-

and-socket joints

In each phase , almost the same muscles are involved . In the transition to the turn , the thrower straightens his arms as the body has to rotate to serve as the axis for the hammer . This is done while the thrower is shifting his weight and still bending . Same muscles are used

In the turn phase , the thrower 's legs will just change position as he rotates turning his hips and readying for the release . His upper and lower body must move as one and his pace and rhythm must not be broken Of course , due force is exerted in the involved muscles

In the release , the thrower will sort of push the hammer , rotating his feet , extending his body and standing with his legs more upright (Medernach , 2007

The common injuries from this sport are arm injuries such as tendonitis , tendonitis , sprains , dislocations and other broken bones Carpal...
