lop a training program using 3/7 training to develop some physical abilities and the digital level of disc tossing for high school sports students and to know its impact on: 1- Special physical abilities (the muscular ability of the arms - the muscular ability of the two legs - the strength of the back muscles - the dynamic balance - the dynamic flexibility) for high school athletic students. 2- The digital level in the disc extrusion among high school sports studentsThe researcher used the experimental method on a sample of 20students from the Secondary School for Sports in Zagazig. They were divided into two groups, one is an experimental group and the other is a control group, each of which 10students Among the research tools: physical tests - measuring the digital level in discus throwing - the proposed training program. Statistical treatments: mean, standard deviation, median, torsional coefficient, simple correlation coefficient, T-test, improvement ratios,%. Among the most important results The training program using 3/7 - training positively affects the special physical abilities (the muscular ability of the arms - the muscular ability of the two legs - - the strength of the back muscles - the dynamic balance - the dynamic flexibility) and the numerical level in the discus flushing of high school sports students. Among the most important recommendations The use of training 3/7 - led to the development of special physical abilities because of its effective impact in improving the digital level in discus ejaculation among high school athletic students - Paying attention to stretching, flexibility and resistance exercises when applying
