The effect of exercises using assistant devices to develop some physical abilities and achieve the long jump for young players aged (15-16) years.

Abstract

The long jump is one of the arena and field activities that depend mainly on maximum speed, explosive power and speed power, which is characterized by a special technical performance that forms the kinetic style of this performance, and by understanding these basic variables and developing training methods based on the use of assistant means and in a scientific and applied method during The training process this category joined. Because of the importance of this and because of the decrease in the digital level and a large difference in the recorded numbers in the long jump event and for the youth age group, the reason for this decline may be due to many reasons, including weakness in physical abilities, especially muscle strength, whether explosive, or characterized by speed as well. The researcher also resorted to use assistant means according to performance that work to help jumpers in training in the right direction and to develop some physical variables, and then develop in achievement for the effectiveness of the long jump.
