Abstract EN

Research Summary: The research included four sections; the first section contains the introduction of the research and its importance.

It was touched upon deep training of muscles using methods and special training methods for these activities, which depend mainly on the mechanical basis of the starting variables such as the angle of advancement and high center of gravity of the body and speed of the body of the jumpers.

The problem of research, there is a decline in the level of achievement at the level of our country and the researcher used biomechanical analysis to extract the research variables on a sample of (7) jumpers and developed deep muscle exercises using a variety of methods.

The researcher concluded that there is a development in some biomechanical indicators for the advancement and achieve the long jump for Youth, The researcher recommended, that you need to be attention to this type of training.
