This study aimed to evaluate the effect of a proposed training program using plyometric training on improving explosive power and long jump performance levels among U18 athletes. The field study was conducted in the Wilaya Athletics League clubs at the level of Chlef province, where the study sample was purposively selected from the original study population, consisting of 10 U18 long jump athletes, representing 62.5% of the research population after excluding (06) athletes. The sample was randomly divided into two groups: an experimental group and a control group, with 5 athletes in each group. In the overall field study, it was necessary to rely on a specific methodology in addition to identifying a suitable tool for data collection that serves the study topic. It was relied on an experimental method to suit the nature of the study. The data collection tool was embodied in the physical tests performed, i.e., the post-tests of the experiment. After data processing, results analysis, and discussion, it was concluded that the experimental group, which underwent the training program using plyometric training, showed a positive effect in developing and improving explosive power and long jump performance levels among U18 athletes.
