The purpose of this study was to evaluate the effectiveness of a 12-week general strength and plyometric training program on sprint and jump performance in prepubertal male football players aged 9 to 11. Twenty beginner players were assigned into two groups the treatment group (n = 10) which received the intervention, while the control group (n = 10) carried with their usual football activities. 30meter sprint, standing broad jump (SBJ), and countermovement jump (CMJ) performance was measured before and after the intervention. The experimental group trained three times per week using a combination of bodyweight strength and plyometric exercises. A mixed ANOVA showed that the experimental group's SBJ performance had significantly improved (p =.027), with the mean distance 1.229 m to 1.482 m. Although not statistically significant, CMJ data showed a positive trend toward improvement (p =.065), with the mean height 20.46 cm to 21.91 cm, The 30M sprint performance showed no discernible differences (p =.295). The findings suggest that general strength and plyometric training effectively enhances lower-body explosive power in young athletes, particularly for horizontal jump performance. Such training in early athletic development may provide long-term performance benefits.
