To ensure allocation concealment, the randomization results will be placed in opaque sealed envelopes, and both the researcher and participants will remain blinded to group allocation until the start of the intervention. N/A The participants had no acute or chronic diseases or lower extremity injuries. The only identified problem was core stability deficiency (weakness in deep trunk muscle endurance) based on the McGill test.. Intervention 1: Control group: The control group received no intervention other than their routine team training. Intervention 2: PRI Group (Core stability exercises using PRI method):Participants performed specific exercises for 8 weeks, 3 sessions per week, aimed at improving postural alignment, trunk and pelvic control, and correcting breathing patterns. The main emphasis was on activating deep core muscles and guided diaphragmatic breathing. Exercises included: 90/90 Hip Lift with Balloon, 90/90 Hemi bridge with Balloon, breathing exercises in various positions, etc. Each session included 5–10 minutes of warm-up and cool-down. Intervention 3: Intervention group: OSAR Group (Core stability exercises using OSAR method):This group also performed 8 weeks, 3 sessions per week of exercises designed to improve neuromuscular control, trunk-pelvis-thigh coordination, and correct lower extremity movement patterns. Exercises were primarily bodyweight without specialized equipment, including: squat, forward lunge, hip hinge, pelvic tilt, modified wall plank with hip flexion, pull-over, etc. Emphasis was on movement control in correct patterns and coordination of breathing with movement.
