Researchers are evaluating how different drop heights in plyometric training affect lower limb explosive strength, anaerobic power, and change of direction COD performance in competitive soccer players aged 18 to 30 years. This randomized controlled trial aims to fill knowledge gaps about training intensity in adult soccer players, focusing on low 30 cm, moderate 45 cm, and high 60 cm drop heights. The study seeks to inform better training plans to enhance athletic performance while reducing injury risks. Participants will be randomly assigned to one of three groups, each performing supervised plyometric exercises such as drop jumps, bounding drills, and box jumps using platforms set at either 30 cm, 45 cm, or 60 cm. Training sessions occur three times per week for six weeks, with 3 to 4 sets per session under supervision. Each group follows the same schedule but differs only by the drop height used during exercises. During the study, participants will undergo assessments before and after the six-week training period, including the Vertical Jump Test, Running-Based Anaerobic Sprint Test RAST, and T-Test Agility Test. These tests measure explosive strength, anaerobic power, and agility, respectively. Researchers will analyze the data to determine changes within and between groups, using statistical software. The total participation time spans the training period plus testing sessions, ensuring comprehensive monitoring of performance changes.

1 visit (in-person)
Duration - 6 weeks
Participants undergo supervised plyometric training using drop jumps, bounding drills, and box jumps on platforms of varying heights (30 cm, 45 cm, or 60 cm). Training consists of three sessions per week for six weeks with 3-4 sets per session under supervision.
3 sessions per week
Duration - 1 week post-intervention
Participants' lower limb explosive strength, anaerobic power, and change of direction performance are assessed 7 weeks after the intervention to evaluate training effects.
