This Biomechanical analytic research aims to know the time distribution, percentage, some momentary and general biomechanical variables (displacement, Velocity, acceleration, and angles), functional anatomical analysis of main articulations and muscles for the performance's stages - subject of research - of Pull circular kick skill (modernized skill) and some private qualitative exercises in Sanda, Kung Fu. And to know the values of Spearman correlation factors in such biomechanical and biological variables between the skill Biomechanical performance and its qualitative exercises and determining the perfect rate for these values as a main criterion to select the skill qualitative exercises. The researcher used the descriptive method through cinematography and 3D movement analysis. The Sample participants was selected purposively of one player ,who holds the world championship of Sanda – Kung Fu on (2013-2016) of (75) kg. He is the only who used the skill under research effictively in different championships. Observation was one of the most important methods for collecting data, The most important results were represented in that the time of performing pull circular kick skill was (0.44) sec and ranging in the qualitative exercises between (0.42-0.52) sec and The least value of time was in the exercise of drop ball and the highest value was in the exercise of elastic triangle. There was a correlation or a great similarity between basic movement variables for the technical performance of the skill under research and all its qualitative exercises range in most studied movement variables between (0.77 - 1.000) and it was the highest correlation in the exercises of punch bags, weights bands and drop ball and the minimum in the exercises of elastic triangle, lion jaws and steering pin . And muscles worked in the main articulation movements through Pull circular kick skill and its qualitative exercises in Sanda - subject of research - that became (32) skeletal muscles distributed on (13) main articulation movements, the top of them is the femur grasping that is Psoasmajor, Iliocostalis and Sartorius muscles. The lower of them is finger flexion in the grasp muscle of fingers.
