AU - بكتاش، إبتسام حيدر AU - فتحي، محمد AB - The objective of this study was to identify the effect of ballistic training on the length and frequency of the step according to the stages of performance and achievement of 100 meters runners. The sample of the study included students of the second year of college of Physical Education and Sports Sciences, University of Kirkuk, 24 students divided equally into two groups (experimental and control) and each group (12) students. The researchers used some tests and measurements for homogeneity and equivalence between the two research groups by (3) training units per week, and the results of the study showed a clear development in performance and achievement of 100 meters runners in general and the rate of the length of the step and frequency according to the stages of the race. The study showed interest in the good design of the training approach according to ballistic exercises because of their role in the development of stages of different speed.
