A COMPARATIVE STUDY OF THE AMOUNT OF FORCE EXERTED ON THE GROUND AND THE TIME OF PROPULSION IN THE VERTICAL AND HORIZONTAL JUMPING TESTS FROM STABILITY USING A FOOT SCAN DEVICE

Abstract

The great development that sports events and games have witnessed in recent years has come as a result of harnessing allied sciences and their applications to increase the effectiveness of training and continuous objective evaluation of the programs and methods used in training. The elements of physical fitness are one of the most important pillars of training that receive the attention of coaches and researchers in order to reach the highest levels of athletic achievement. The researchers were keen to design and master objectivity to measure physical characteristics from time to time to ensure the validity of these tests and thus give real results that express the levels of players in various sports activities.The characteristic of explosive power is one of the important complex physical characteristics, which constitutes the most important factor in many sports events and games.The tests designed to measure explosive power are characterized by complexity, which may make their results inaccurate.The great development of science has helped a lot in the development of testing and measurement, which has been reflected in the development of achievement. Using advanced devices, we can judge objectively and conclusively without there being the slightest doubt about a particular matter. One of these devices is the Foot Scan device, which gives conclusive indicators. There is no doubt about the amount of time of pushing and the force exerted on the ground by the muscles of the legs, as well as determining the strengths and weaknesses of the feet.It is known that two of the most important tests for measuring the explosive power of the lower limb muscles are the vertical jump from a standstill and the horizontal jump tests. However, it is not known which of the two tests is the most appropriate and most expressive for measuring explosive power. Accordingly, the importance of research lies in identifying the most appropriate test for measuring explosive power. Muscles and using a Foot Scan device to judge objectively and scientifically about the most appropriate test without relying on personal opinions, judgments or personal experience, in addition to obtaining indicators of strength and time
