Does three sessions of 12-week plyometric training per week improve physical fitness parameters in professional male soccer players? A randomized controlled trial

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…
