KINESIOLOGY-analysis of movement.

The movement that the shall discuss is the `hammer throw ' The modern or HYPERLINK "http /encyclopedia .thefreedictionary .com /Olympic Games " Olympic hammer throw is an HYPERLINK "http /encyclopedia .thefreedictionary .com /athletic " athletic throwing event where the object to be thrown is a heavy HYPERLINK "http /encyclopedia .thefreedictionary .com /steel " steel ball with wire (maximum 4 ft (1 .22 m ) to a handle (Farlex Inc , 2007 ,

.1 The objective of the feat is throwing the steel ball at the farthest distance . The two most important factors for a far throw are the angle

of release and the speed of the ball (Farlex Inc , 2007 ,

For an athlete , it is important for them to be aware of every muscle movement that happens during the process of hammer throw . These phases are important for a smooth transition of muscles from one stage to another to execute a correct and efficient movement . The next part will highlight the five phases involved in hammer throw . In particular , the following phases will determine the relevant muscles involved in the process

The first phase involves the stance phase . There is minimal amount of movement in this phase that is why muscles remain at status quo . Due to the minimal amount of movement in this phase , the majority muscle position maintenance throughout the body should be accomplished through isometric contraction (www .mhhe .com /floyd16e ,

The next phase involves the preparatory phase . In hammer throw concentric contractions occur in their anatagonist muscles in this phase (www .mhhe .com /floyd16e ,

.196 ) The joints involved are the shoulder and elbow in which their actions represent a horizontal hyperextension and extension respectively . In addition , the agonists muscles involve in the process are posterior deltoids and latissiumus dorsi and triceps brachii (shoulder and elbow

The third phase talks about the movement phase . It is the phase in which the summation of force is generated directly to the ball , sport object , or opponent , and is usually characterized by near-maximal concentric activity in the involved muscles (www .mhhe .com /floyd16e br

.197 ) With hammer throw , this is the process wherein the person starts rotating the body which is called `turns . You must try to utilize inertial forces of the hammer in the single by riding the ball and being passive with the ascending hammer , while avoiding activity with the pelvis and legs (Larry , 2000 ,

. 1 ) In addition , After running through the high point of the hammer , you must complete the turn on the ball of the left foot by actively driving back to double support as soon as possible (Larry , 2000 ,

The next phase involves the follow-through phase . In this phase often referred to as the deceleration phase , the velocity of the body segment progressively decreases , usually over a wide range of motion In the process of hammer throw , the joints involved are the shoulder and elbow . The actions involved are a horizontal flexion and flexion for the shoulder and elbow respectively . The agonist...
