This research aims to identify the effect of the use of varying training and its effect on some special physical, biomechanical and digital levels of long jump contestants. The researcher used the experimental method of pre and post measurement for one experimental group in order to suit the nature of this research, on a sample of (9) players. Divide them into (5) players for the basic study and (4) players for the survey study from the same research community. The results revealed that the use of varying training had a positive effect with statistically significant differences on the special physical abilities and some biomechanical variables of the long jump contestants of the individuals of the research sample. The researcher recommends the need to pay attention to the use of differentiated training to develop the special physical abilities of the long jump contestants and the importance of having follow-up records for each contestant in which (special physical abilities - special biomechanical variables - digital levels are recorded) and to conduct more scientific studies that deal with the effect of differential training in other training forms in field competitions. And the track in all its forms.
