The research aimed to develop a program using cluster exercises and to know its effect on the following: 1- Special physical capabilities (muscular ability of the legs - transitional speed - muscular strength of the legs - flexibility of the torso and thigh - rebound strength index) for long jumpers under 16 years old. 2- The digital level for the long jumpers under 16 years old. The researchers used the experimental method on a sample of (12) junior long jumpers under (16) years old, they were divided into two groups, experimental and control, each group consisted of (6) juniors, and among the research tools: physical tests - measuring the digital level in the long jump - measuring the rebound strength index . Statistical treatments: (arithmetic mean, standard deviation, median, skewness coefficient, simple correlation coefficient, T test, Wilcoxon test (y) - Mann Whitney test (j), improvement rates (%)). *The researcher has adopted Significance level 0.05 limit of statistical significance. Among the most important results: 1- The use of cluster group exercises has a positive, statistically significant effect at the level (0.05) on the special physical capabilities (muscular ability of the two legs - transitional speed - muscular strength of the two legs - flexibility of the trunk and thigh - rebound strength index (deep jump)) of the long jump juniors under 16 years old. year. 1- There are improvement rates for the post-measurement from the pre-measurement of the experimental research sample in physical abilities and the digital level. The researchers recommended the importance of: using the cluster group training method to improve the physical and skill level of the athletics competitors, and benefiting from the proposed training program to improve the physical variables of the long jump and the level of performance of juniors.
