The evaluation of the ideal athletic performance in terms of the absolute angles

Abstract

The scientific development that the sports events witness in the present time is strongly related to the technological development. Thus, the modern technical means such as developed devices and programs contributed in adopting scientific ways that lead to the finding of the most suitable, appropriate and economical kinesthetic paths for the athlete’s body, using the best and modern ways of the kinesthetic analysis, which has a big role in diagnosing the mistakes and weakness and strength points of the athletes, for the fact that trainers base their work only on monitoring will not lead to the sufficient diagnosis of the mistakes, due to the speed of the movement during the performance, which leads also to the recognition of the effects of athletic training on the development of the physical abilities and applicable and mechanical indicators… etc. the aim of this research is to shed the light on the evaluation of the ideal athletic performance in terms of the absolute angles from a biomechanical perspective. Thus, through the recognition of the notion of the absolute angles and the transmission of the movement between them. Also knowing their relationship to the central and noncentral contraction of the muscle. Finally, we reached the following: i. The fulfillment of the required torque is related to the principle of the central contraction of the muscle, which is related to the main duty of the movement. ii. Whether the angle is relative or absolute, torque is the reason that the body or parts of body have (speed, acceleration and angular momentum) The most important recommendation: it is obligatory not to name the angle by the name of the joint itself only, because the joint is the axis of the rotation that the body or part of the body rotate around it.
