Volleyball Serve
In any given volleyball match, the only opportunity a team has to score comes when they possess the serve. Often times in contest between two evenly matched teams, the difference in the game is determined by which team is able to serve the most consistently. The defensive team is unable to score points. Because of this, it is imperative that all players on a volleyball team are consistent in their serving, in order to keep the serve and not allow the opposing team the opportunity to score points for themselves. The serve constitutes the beginning of every play. If a team is unable to put the ball into play on the offensive side of the ball, they will be unable to score points, and thus will probably win few games.In learning the proper serving technique, it is imperative to remember that the key to eliminating serving errors is minimizing movement. For example, the lead foot should start in the lead, not behind. Also the toss should only be two feet above the head. Adjustments to minimize motion within the serve will help to eliminate chances for errors. An effective way to teach proper serving form to beginners breaks the serve down in to four different phases: platform, lift, step, and hit.
Also in the toss arm, the elbow is slightly flexed, involving the biceps, brachialis, bracioradialis, and pronator teres. The strike arm is also flexed and resting on top of the ball,also using the anterior deltoid and the supraspinatus, with the hand pronated on the ball. As the knees flex, the humerous of the toss arm extends slightly through the sagittal plane,using the posterior deltoid,the latisimus dorsi,and teres major and the pectoralis major. The knees, using the biceps femoris, the semitendinosus, and the semimembranosus flex to a lesser angle as do the hips, using the iliacus, psoas major, and the rectus femoris. It is the phase in which the initial movement and the overcoming of inertia of the ball take place in the form of the toss. The knees should be slightly flexed, using the biceps femoris, semitendinosis, and the semimembranosis. This phase incorporates Newton's first law of motion. With the tossing arm, the hand is supinated using the supinator, biceps brachii, and the brachioradialis, and the humerous is flexed in the sagittal plane at an angle of approximately 90 degrees. In the flexion of the humerous, the anterior deltoid and supraspinatus are being used. important to the initiation of movement in the serve. Simultaneously, the biceps, brachialis,bracioradialis,and pronator teres of the strike arm cause it to further flex at the elbow joint, as the humerous experiences an even greater degree of flexion, an angle greater than 180 degrees. Any pre-serve ritual a player may have, such as dribbling,etc. This creates an added potential energy and rebound in the muscles. It raises above and behind the head,incorporating not only the anterior deltoid and the supraspinatus,but the posterior deltoid,subscapularis,infraspinatous,and the teres minor, which are used to pull the head of the humerous down in order to allow the strike arm to be raised above the head. Because the serve is so vital to the game of volleyball,it is imperative that it be one of the most consistent and efficient skills a player develop when learning the game.
