Introduction: Plyometric training is widely recognized as an effective method for enhancing explosive physical performance in sport.
Objective: This study aimed to examine the effects of an eight-week plyometric training program on selected physical abilities and kinematic variables in youth female football players. Methods: A quasi-experimental pre–post design was employed involving adolescent athletes aged 15–17 years. Participants were allocated according to team training schedules and logistical considerations; therefore, randomization was not feasible. Performance variables included explosive power, agility, muscular endurance, and hopping ability. Kinematic variables such as step length, step frequency, and running velocity were also assessed using standardized field tests and video-based analysis.
Results: The experimental group demonstrated significant improvements across all physical performance variables compared with the control group. Explosive power and hopping performance showed the greatest relative gains. Agility improved significantly, reflected by reduced completion times. Kinematic analysis revealed increased step length, running velocity, and effectiveness index, whereas step frequency showed no significant change. Effect size analysis indicated large practical effects of the plyometric training program.
Conclusions: Plyometric training may represent a practical training strategy associated with improvements in physical performance and selected kinematic variables in youth female football players. Coaches are encouraged to incorporate structured plyometric exercises into training programs to optimize neuromuscular development and sport-specific performance.
