This study aimed to investigate the effect of static stretching and full dynamic stretching exercises using elastic resistance bands on the development of motor balance and dynamic flexibility in youth basketball players. The research sample consisted of (12) youth players from Al-Adhamiya Sports Club basketball team, who participated in a training program utilizing elastic resistance bands alongside their regular training for a duration of (8) weeks, with (3) training sessions per week. To measure the study variables, the Modified Bass Test of Dynamic Balance was used to assess motor balance, and a dynamic flexibility test was employed to evaluate movement flexibility. The results revealed statistically significant differences between the pre- and post-tests of the experimental group in both motor balance and dynamic flexibility, in favor of the post-test, indicating the effectiveness of the training program using elastic resistance bands in improving these physical abilities. The researcher attributes this improvement to the nature of elastic resistance exercises, which provide progressive resistance throughout the full range of motion, thereby enhancing neuromuscular balance and increasing joint range of motion. Furthermore, the findings showed that training opposing body segments contributed to improving muscular balance and reducing asymmetry between the two sides of the body, while static stretching exercises enhanced muscular stability and neuromuscular control, and full dynamic stretching exercises contributed to increasing functional range of motion associated with basketball skill performance.
