In the sport of boxing the upper cut is a punch that usually aims at the opponent's chin that can cause great harm at close range if executed properly. We conducted an experiment using a novice subject who was told to perform an uppercut motion ideal to the motion used in the sport of boxing. The action was taped so we could observe the subjects motion and what significant and non significant joints, ligaments, and muscles were at work. Then we determined the phases of movement and formulated ideal movements for an uppercut. With the ideal movements formulated we concluded with recommendations for the subject's improvement in performing an uppercut. Bones provide attachment points and support for muscles, and are connected by fibrous tissue called ligaments. Joints provide a fulcrum point for muscles to do work that is limited to the restriction of the ligaments. The uppercut motion uses the ball and socket joint for the shoulder for a circular movement, where the elbow uses
The legs cross the frontal plane too when the subject steps into the punch and the legs switch; front to back on one leg and back to front on the other. The hinge joint allows the arm to extend and flex the arm, and the pivot joint allows the forearm to turn back and forth. After the subject was ready in the stance the motion begins by extending the arm back, or increasing the arms joint angle. You then initiate the movement by snapping your shoulder forward and up while stepping into your punch. The correct way to execute an uppercut starts by holding the arm close to the body keeping the elbow bent, low, and tucked in tight. Sense we did not give our subject a direct target to punch they were picking a fight with air. If executed well the uppercut can do great damage to the opponent and even lift them of their feet on to the ground. The arm also crosses the horizontal plane which divides the body from upper to lower. It's not a wild swing that should twist the subject and leave them unbalanced. The hand should be closed tightly and you should curl you wrist inward. The anterior deltoid functions to flex and extend the arm. The weight of the subject is then applied to the front leg and the arm is snapped forward, or flexed meaning a decrease in joint angle, while stepping into the uppercut punch. The long head works with the anterior deltoid to raise the arm to the front. In the experiment the subject had their legs bent, arms bent, and fist closed tight.
