Posture, Proprioception, Core Stability, and Balance in Weightlifters

This study aims to examine whether the posture of the upper back (thoracic kyphosis) is related to body awareness, core stability, and balance in people who regularly participate in weightlifting. Participants will undergo assessments of thoracic posture, proprioception, core stability, and dynamic balance. The study will also compare these measurements between different groups of weightlifting athletes.
