Today, due to the expansion of diversity, activities and different sports disciplines in professional sports and championships at the international level, it is necessary to have a targeted and detailed examination of basic skills. Basic skills have a fundamental defect in expanding and improving sports activities, which requires systematic and up-to-date exercises to improve these skills. One of these basic skills, which is used in most sports, is the skill of jumping. There are different jumps in sports, one of the most widely used of which is the vertical jump. Vertical jump is a skill that is used in most sports. And also, as one of the important and fundamental factors in many sports fields, strength plays an important and fundamental role in the success of athletes. Therefore, the main aim of this study was to compare the kinematic behavior of the knee joint in the execution of the counter-movement jump of male students of physical education following the squat movement with a combined load, elastic stretch, weight and following weight training. The statistical sample of this research was 20 male physical education students with an average age of 21 ± 2.00 years, who were available. During the three days of the test, the subjects were randomly divided into three groups: control, combined training and weight training. After three minutes of rest, the group of combined exercises and weights performed the squat movement with maximum weight and the anti-movement jump movement with maximum strength. The results of the research showed that between the average maximum flexion of the knee joint during the eccentric phase before and after (landing) of the jump (p=0.000, p=0.002). There was a significant difference between the average maximum angular velocity of the knee joint during the eccentric phase before and after the jump, the maximum angular velocity of the knee joint during the concentric phase of the jump among the three training conditions (p=0.000, p=0.000) between the jump height There was a significant difference among the three training conditions. (p=0.000) It is worth mentioning that the highest jump height was after combined exercises, although there was no significant difference between the combined and weight group. (p=0.06) In general, doing maximal strength exercises with two combined methods and weight improves jumping ability performance (jumping height, angular velocity of the knee joint).
