Abstract: Background: Plyometric training is an effective training method and widely recognized for improving neuromuscular performance, particularly lower extremities strength and vertical jump height required in football. However, evidence on its effectiveness among young amateur football players remains limited. Objective: This study aimed to evaluate the effect of a four-week plyometric training program on lower extremity strength and vertical jump performance in young amateur male football players aged 16–20 years. Methods: A pre–post quasi-experimental design was conducted on 25 amateur male football players aged 16 to 20 years with minimum of two years of training experience in football game. Participants underwent a four-week structured plyometric training protocol, consisting 12 supervised plyometric sessions performed three times per week, incorporating progressive jump based plyometric exercises. Lower extremity strength was assessed using the One Repetition Maximum (1RM) Squat Test, and vertical jump performance was measured using the Sargent Vertical Jump Test. Statistical analysis was performed using paired t-tests with a significance level of p < 0.05. Results: Significant improvements were observed following the intervention in both outcome measures. Mean absolute 1RM increased from 47.72 ± 6.86 kg to 54.64 ± 7.27 kg (p < 0.001), while relative strength improved from 0.75 ± 0.06 to 0.86 ± 0.08 (p < 0.001). Vertical jump height increased from 37.20 ± 3.25 cm to 41.52 ± 3.89 cm (p < 0.001). These findings confirm that short-term plyometric training effectively enhances lower-limb strength and explosive power. Conclusion: The study concludes that the structured four-week plyometric training program produces significant improvement in lower extremity strength and vertical jump performance among young amateur football players. The improvements are attributed to neuromuscular adaptations and enhanced stretch-shortening cycle efficiency. Plyometric training can therefore be considered an effective, time-efficient method for improving football performance in young amateur athletes.
