Background. Plyometric training is recognized for enhancing various physical fitness parameters critical to athletic performance, particularly in soccer players.

Purpose. This study aimed to assess the effects of a 12-week plyometric training program, conducted three times per week, on key fitness parameters in professional male soccer players.

Methods. A total of 40 professional male soccer players were randomly assigned to a control group (CG, n=20) and a plyometric training group (PTG, n=20). Participants (mean height = 176.14±3.28 cm, weight = 68.24±2.17 kg, and age = 20.31±2.30 years) underwent a 12-week plyometric training intervention. Fitness assessments were conducted before and after the intervention, measuring agility (t-test), balance (stork stand test), speed (50 m dash), power (medicine ball throw test), explosive power (vertical jump), leg strength (standing broad jump), and core strength (sit-up test).

Results. Significant improvements (p < 0.001) were observed in the PTG across all fitness parameters compared to the control group, indicating the effectiveness of plyometric training in enhancing physical fitness in soccer players.

Conclusion. The 12-week plyometric training program positively impacted agility, balance, speed, power, explosive power, leg strength, and core strength in professional male soccer players, suggesting it as a valuable regimen for improving overall physical performance.
