The mechanics of a baseball swing
The biomechanics of the baseball swing can be described four phases: Stance, Recoil, Swing, and Follow through. Previous studies have been completed on the biomechanics of a baseball swing in an effort to perfect the art of the perfect swing. First I am going to discuss the stance. It is important that the batter stand in a position that is most comfortable and allows for balance at all times. The player's body weight should be slightly distributed on the back leg with the feet being about shoulder width apart. The hips and shoulders are kept level with the front hip, which is the left hip. It is important to maintain relaxation during this phase. The bat is held at about chest level, while the elbows are out and the wrist is hyper-extended. The muscles that hyperextend the wrists are the Extensor Carpi Radialis Longus, the Extensor Carpi Radialis Brevis, and the Extensor Carpi Ulnaris. The muscles that keep the shoulders flex
The muscles that are involved in trunk rotation are the Internal Obliques and the External Obliques. The muscles that horizontally adduct the shoulder are the Corocobrachialis, Pectoralis Major, Anterior Deltoid, Teres Major, and the Latissimus Dorsi. At the moment of contact, the elbows are extended and the shoulder are forward flexed at 90-degrees. The Latissimus Dorsi muscles inability to generate tension results in the batter's left shoulder tilting upward and backward. Both arms are fully extended; however the left Biceps Brachii, left Brachialis, and the left Brachioradialis act in order to prevent hyperextension of the left arm. The follow through begins after contact is made with the ball. The muscle involved in flexing the spine is called the Erector Spinae. Also at the time of contact, the arms fully extend and the wrists break. The muscles that flex the elbows are the Flexor Carpi Radialus, the Flexor Carpi Ulnarus, the Pronator Teres, the Biceps Brachii, the Brachioradialis, and the Brachialis. The initial motion of a baseball swing is known as the Recoil phase or Loading phase. Here the left Pronator Teres, and the left Pronator Quadratus pronate the left arm. Now I am going to discuss the Swing phase. Finally, I am going to discuss the Follow through. The elbows are flexed at a 45-degree angle. This causes the trunk of the hitter to move away from the pitcher.
