| Abstract | ||
| The study of the athletic movement mechanism in all types of sport activities and the field of training the movement scales specially the part that connected to study the elements that take direct or indirect effects on the scale act of movement. Those elements are very important and they are varied among biological, physiological, anatomical, social, psychological and the most important one among them the mechanical elements that collect the theoretical material and explain the interfered relations among these elements and the connections natural of the elements, to get ideal movement samples that reduce the efforts of learning and training and improve the movement mechanism act to reach the best results. The researches take its importance from the development of positive sides and concentrate on it, until the weight lifter reach a progressive results, from here the problem of research starts to detect the effect of the kinematics variables each one another and anew style appear which is squite jerk that achieve a high world scores the researchers start comparative study between spelt jerk and squite jerk styles. After monitoring the Nenava weight lifter team the data analyzed and processed statistically the result found that there are differences between the two styles for the variables (H3,H4),the research final result obtain that, spelt jerk style is more suitable for the players that have stronger upper parts with low flexibility, in other side squite jerk style is suitable for players that have stronger lower parts (legs)with high flexibility in the upper parts and high drop speed under the bar. | ||
