It is already clear the importance of resistance training with elastic bands to improve the level of performance compared to more traditional drills .So the present study aimed to identify the effect of functional resistance drills with elastic bands on some of physical and biomechanical variables and kicking accuracy in soccer junior. Experimental method was used; (pre-test & post-test), with a single experimental group, from fifteen soccer Junior (aged 17.54 ±0.7 years, body mass: 67.84 kg, height: 171.53cm) constituted one experimental group. and (5) junior for pilot study (n=15), functional drills and the pretest–posttest are done during specific prep phase of training with duration 10-weeks training program for (3 training units per week for 2hrs), Repetition (8-12), and (3-5) sets. after the functional resistance drills finish, biomechanical analysis was performed using motion analysis Program (win analyze) computer-assisted. It was a post-test to compared the pre-test by using statistical procedures: (Mean - standard deviation – Median - Coefficient of Skewness – T-Test ), and discussion it was possible to conclude the Functional resistance training using elastic bands has improved values of the biomechanical variables under study in post-test, it is improved performance of kicking in front of the front foot on goal, as well as led to kinetic bonding between the leg joints (Hip- Knee- Ankle) in backswing and impact phases while kicking performance. Study shows that there are statistically significant differences between the mean (pre-test and post-test) measurements of the study sample, with pre-test at the level (0.05) in all physical variables and accuracy and kick timing, this is confirmed by the results this study, where Static balance (3.632 s) Muscle strength for back extensors mean was (70 Kgf), Muscle strength for legs extensors mean was (131 Kgf), Quadrant jump test mean was (3.166 s), High jump from stability mean was (76.33 cm) Illinois agility mean was (11.530 s), Accuracy kick mean was (4.833 Deg.) and Kick timing mean was (0.278 s).
