The effectiveness of muscle strength exercises in balancing the muscles of the arms and shoulders and their impact on some of the Kinematic variables of straight punches

Abstract

Boxing one of the sports which is characterized by specified number of rounds interspersed with short breaks. The boxer performs offensive, defensive and counter-offensive skills from various punching distances; continuously and effectively, taking into account the correct technical performance requirements characterized by being forceful, rapid, proactive and enduring since the beginning of the game until the end in order to win and achieve higher scores. Training should be designed to be compatible with the requirements of boxing. The boxer should have high physical efficiency during the game so that he can strike the greater number of punches and effectively finish the game. Muscle strength is one of the most important physical elements for boxers. Boxing is mainly based on the ability of the muscles to contract and expand, as well as working alternately to perform limb movements. The more powerful are the muscles the more effective are the contractions. Abu Ela Abdel-Fattah (1997) defines muscular balance as the strength of one muscle or muscle group and its correlation to another muscle or other muscle group. Terzis, G., & Al, (2003) believes that speed distinctive strength exercises for the muscles of the arms; particularly the triceps muscle, as they have a positive impact on the level of technical performance. The rapid and powerful movements of the boxer lead to stressing the tissues of the body (tendons-muscles-ligaments) and makes them vulnerable to injury. Therefore, strength training increases the connectivity of the tissues connecting the body parts and help preventing injury.
