The research aimed to develop a program using weight training and specific plyometric exercises, and to know its effect on the following: 1- Special physical abilities (muscular ability of the two legs- transitional velocity - maximum muscle strength of the two legs- elasticity of the torso and thigh) for young hikers under 18 years of age. 2- The digital level for young jumpers under 18 years old. The researcher used the experimental approach on a sample consisting of (10) young and long jump under (18) years, and among the research tools: physical tests - measuring the digital level in the long jump - weight training program and the proposed specific plyometric exercises. Statistical treatments: mean, standard deviation, median, torsional coefficient, simple correlation coefficient, T-test, improvement ratios,%. Among the most important results: 1- The use of specific weightlifting and weightlifting exercises a statistically significant effect at a level (0.05) on the special physical abilities (muscular capacity of the two legs -transitional velocity - maximum muscle strength of the two legs - elasticity of the trunk and thigh) among young jumpers under 18 years of age. 2 - The presence of improvement ratios for the dimensional measurement from the tribal members of the main sample in the special physical abilities under investigation ranged between (5.55% - 22.88%). 3- The use of weight training and qualitative palliative exercises has a positive statistical significance at level (0.05) on the digital level for young jumpers under 18 years old. 4- The presence of an improvement rate for the dimensional measurement from the tribal members of the basic research sample at the digital level in the long jump reached (7.89%).
