The research aimed to develop a training program using unified and multidirectional training for handball players under (20) years and to know its impact on physical and physiological variables and the level of performance (strength - accuracy) high jump shot, and the researchers used the experimental method on a sample of 20 handball players under (20 years , They were divided into two experimental groups. The first experimental group used (unified direction training), and the second experimental group used (multi-directional training) the strength of each of them (10) handball players, and from the research tools: Physical tests - skill tests - physiological measurements, and the statistical methods used in the research: arithmetic mean - standard deviation - median - torsion coefficient - simple correlation coefficient - T-test - improvement rate. Among the most important results: – The unified and multi-directional training methods have a statistically significant positive effect at the 0.05 level on the physical and physiological abilities and the level of high jump shooting performance in handball. – There are statistically significant differences between the mean of the dimensional measurements of the two experimental groups: the first experimental (unidirectional training) and the second experimental (multi-directional training) in the physical and physiological abilities under study and the level of performance of high jump shooting in handball in favor of the second experiment. – The members of the second experimental (multi-directional training) outperformed the first experimental members (the unified directional training) in the rates of improvement of the telemetry from the tribe in the physical and physiological abilities under study and the level of performance of high-jump shooting in handball.
