Implementing biomechanics to study motions of judokas through kinovea software for enhancing their performance & maintaining center of gravity during throwing techniques

Abstract

Judo is world famous game and art of hand-to-hand combating with peaceful mind. There are different techniques of Judo which include different motions of legs & knees, arms, trunks and head to generate required force to perform a technique effectively. Some techniques involve maximum use of limbs when other requires perfect use of head, trunk and limbs in locomotion of Judokas during competition. The winning is dependent on how perfectly the Tori (attacker) applied combination of his muscles power to lift up lever at right position, generate required force to be concentrated on focus to displace the Uke(defender.) Applicability of Biomechanics turned the Judo art into more scientific game that assist in describing the required force by each body motion during fighting. Biomechanical appliances on tradition Judo helps in improving the traditional methods, performing more logically and accurately. The current paper just focus on the throwing techniques of Judo in which whole parts of the Tori ‘s body work in together to off-balance the Uke’s body. The paper highlights how body parts act as lever to shift the maximum force at a particular point while maintaining the center of gravity in throwing the Uke’s body without misbalancing itself, avoiding injuries in head, backbone & its lower part near sacrum. Kinovea software is used to study the locomotion of Judokas at different points, track the speed & distance of body motions and path traced during practice that is discussed in the paper.
