Enrollment: 30
Sex: MALE
Minimum age (years): 18
Maximum age (years): 23
Standard ages: ADULT
Accepts healthy volunteers: yes
Allocation: RANDOMIZED
Intervention model: PARALLEL
Intervention model description: Participants were randomly assigned to one of two arms: (1) Core training group, which performed a 4-week structured core exercise program in addition to their routine training; (2) Control group, which continued regular training without additional intervention.
Primary purpose: TREATMENT

Brief summary: This study aimed to investigate the effects of a 4-week core exercise program on sprint, vertical jump, agility, and postural sway performance in amateur male soccer players aged 18-23. Participants were randomly assigned to an intervention group (core training) or a control group (regular training). Physical performance tests were conducted before and after the training program. The results are expected to help coaches and sports scientists better understand the performance benefits of core training.

Detailed description: This randomized controlled study investigated the effects of a 4-week core exercise program on sprint, vertical jump, agility, and postural sway performance in amateur male soccer players aged 18 to 23. Thirty participants were randomly assigned to either a core training group (n=15) or a control group (n=15). The core training group performed additional core stability exercises three times per week, while the control group continued their regular training routine. All participants completed physical performance tests, including 10- and 20-meter sprint, change of direction test, countermovement jump (CMJ), and postural sway assessment using a force platform. Pre- and post-test comparisons were conducted to evaluate the intervention's effectiveness. Ethical approval was obtained from the Gazi University Ethics Committee (Approval No: 2024-1685). The study was designed to help coaches and sport scientists understand how core training may improve athletic performance parameters in amateur football players.
