This research aims to design a training program using special physical abilities in order to identify the effect of the training program on developing some special physical abilities for tennis juniors under 12 years old. The researcher used the experimental method for its relevance to the type and nature of this research, through the experimental design using the tribal and remote measurements of the same group. The researcher chose the research sample in a deliberate way from tennis juniors under (12) years old at the Grand Slam Academy in Zagazig, which is registered with the Egyptian Tennis Federation Where the total sample strength reached (12) emerging (the basic sample, the exploratory sample).Where it is divided into the basic sample (6) juniors from those who are regular in the application of the training program, in addition to a sample of survey studies, numbering (6) juniors from the same research community and from outside the basic research sample. The program was implemented by (3) training units by (24) daily training units during the application period, and after the completion of the application of the training program under discussion, dimensional measurements were made, then a sample of the study was conducted, the data was processed statistically, and then the results were presented and discussed, And the most important results were that there are statistically significant differences between the two measurements, the pre and post measurements, in the variables under consideration, and in favor of the post measurement of the experimental group.
