The research aims to                                                                                                                      

1.Prepare special exercises to develop the strength marked by the speed of the two feet, agility and the movement of the feet in defense of  the young football players .                                       

2.Identify the effectiveness of special exercises in the strength marked by the speed of the two feet, agility and the movement of the feet in defense for the young players in football.                 

To achieve  the research objectives, the researcher developed the following hypothesis, which is the existence  of statistically significant differences between the results of the pre and posttests   of the experimental group in the strength marked by the speed of the two feet, agility and the movement of the feet in defense of the young players in football.                                                 

The research procedures included achieving homogeneity in the strength test for the speed of the two feet, agility and the movement of the feet in defense for the players identified by the researcher, and a training curriculum was designed and applied to the experimental group of young athletes of  Alshurtaa(Police) Sports Club ,totaling (20) players. The researcher  used the experimental approach because it fits to achieve  the research objectives  and also conducting several pilot studies to overcome problems and difficulties in performing special exercises as well as  identifying the appropriate stresses and repetitions and appropriate times of rest for these exercises, which are appropriate to the research sampl.Then, pre-tests were conducted for the variables (under research), then the experimental group implemented the training curriculum prepared by the researcher. The implementation of the training curriculum took (8) weeks during two intermediate courses, at the rate of (4) micro-courses for one session, and (2) training units for one micro-course, and with a ripple (1: 3) and the researcher conducted the post-tests in the research variables with the same procedures and steps that were followed in pre- tests  , and data were Statistical
