The research aimed to develop a training program using collision exercises on the special physical variables and electrical activity (EMG) of the leg muscles and the digital level of the long jump child under (18) years. And to know its effect on: 1- The physical variables of the long jump child under (18) years are under investigation. 2- The electrical activity (EMG) of the leg muscles for the long jump child under (18) years, under research. 3- The digital level of the long jump youngster under (18) years under investigation. The two researchers used the experimental method with one experimental group, and the two researchers selected the research sample by the deliberate method from a young person from the Sharqah region and registered in the Egyptian Athletics Federation under (18 years) for the training season 2020/2021 AD, where the number of the basic sample reached (10) youngsters in addition to the pilot study sample And their number (7) emerging from within the research community, bringing the total sample total (17) emerging. Among the research tools are: Special physical tests - Measurement of electrical activity (EMG) for the muscles of the legs - Measurement of the digital level of the long jump child under (18) years - the proposed training program Statistical treatments: mean, standard deviation, median, torsional coefficient, simple correlation coefficient, T-test, improvement ratios,%. The most important results: 1-Training using crash drills has a positive effect on improving the physical variables of the long jump arising. 2- Training using crash drills has a positive effect on improving achievement motivation for long jumpers. 3- Training using crash drills has a positive impact on improving the digital level of the long jumpers. Recommendations: 1-Attention to collision exercises because of their positive impact on the physical variables for the long jump competition. 2- Using the proposed training program because of its positive effect on the electrical activity of the leg muscles of the long jump child. 3- Using the proposed training program because of its positive impact on the digital level of the long jump child.
