Abstract
SummaryThe biomechanical analysis of the pushing kick in the conventional free combat was aimed at the crowds with different ages and different types of skeletal muscles. The analysis precision was low. Therefore, this article put forward the biomechanical analysis of push‐kick of free combat based on 3D image. Three‐dimensional image technique and Hill equation were used to construct the biomechanical model of muscles of free‐combat athletes and describe the leg mechanics in the kicking process. Pattern system provides an up‐to‐date and authoritative fuzzy model, which is an intelligent recognition algorithm. Then, the image analysis was used to build the motion model of knee joint, so as to determine the dynamic equation of knee joint of pushing kick. Based on the above model, the characteristics such as the strike force of push kick, the peak characteristic of leg joint angular velocity and the joint torque were analyzed to achieve the biomechanical analysis of the pushing kick in free combat. Experimental data show that combined the proposed biomechanical analysis method with the traditional analysis method, the precision has improved by 47.69%. Meanwhile, it is suitable for the biomechanics analysis of different free combat crowds.
