Participants in this group received supervised slackline training sessions three times per week for six weeks. Each session lasted 45 minutes and included dynamic balance and core stabilization exercises performed on a slackline. A total of 18 sessions were conducted. The training was delivered by qualified instructors in a controlled indoor environment.

Participants in this group did not receive any structured intervention during the study period. They were instructed to maintain their usual daily routines without engaging in any specific balance or core training activities. No supervised sessions or exercise protocols were applied.

This intervention consisted of a six-week supervised slackline training program designed to improve core stability, physical performance, and dynamic balance. Participants in the intervention group performed 18 sessions (3 sessions per week, 45 minutes each) using a Gibbon-brand slackline (12.5 meters in length, 50 mm wide). The training protocol included a structured progression of 11 exercises, ranging from assisted standing to unassisted long walks and dynamic movements on the slackline. All sessions were conducted under the supervision of a licensed physiotherapist to ensure participant safety and training fidelity. Exercises were adapted weekly to increase difficulty, challenge motor control, and stimulate neuromuscular adaptation.

Trunk Flexion Test: The participant was positioned with back support, knees and hips flexed at 90°, feet fixed on the bed, and arms crossed over the chest. The trunk was set at a 60° flexion angle from the bed. Before removing the back support, the participant was instructed to maintain the trunk position for as long as possible Trunk Extension Test: The participant was positioned with their spina iliaca anterior superior aligned with the edge of the bed. They were instructed to place their hands on opposite shoulders and maintain the upper trunk in a horizontal position for as long as possible Prone Bridge Test: The participant was positioned prone, with hands, elbows, and feet shoulder-width apart. They were then instructed to lift their pelvis off the bed and maintain this position using only the toes, forearms, and elbows as the support surfaces Side Bridge Test: The participant was positioned on their dominant side on the bed, with the support arm flexed at the elbow, knees and
