Background: Running, a fundamental motor skill, evolves with experience, significantly influencing coordination and thoracic mobility. Our study aims to investigate whether prolonged engagement in running could result in distinct variations in thoracolumbar mobility and kinematic efficiency among individuals with varying levels of running experience. Methods: This study examined thoracic mobility among sedentary individuals and runners who have been running for the last six months and the last two years. Measurements included latissimus dorsi (LD) muscle tone, elasticity, stiffness, trunk flexibility and range of motion (ROM), lumbar extensor shortness, thoracolumbar fascia (TLF) length, and the modified Schober test. Results: LD tone was lower in six-month runners, while sedentary individuals had the greatest LD elasticity and stiffness. The modified Schober test results indicated that the six-month runners scored the highest. Two-year runners had significantly greater dominant-side lateral flexion than sedentary individuals and six-month runners. TLF length was highest in running for two-year runners. Two-year runners exhibited the greatest dominant-side lateral flexion, while six-month runners showed more flexion and two-year runners more extension. Conclusions: Prolonged running experience may enhance thoracolumbar mobility and muscle tone. Furthermore, the observed stiffness and reduced elasticity in sedentary individuals highlight the detrimental effects of inactivity on spinal and muscular health.
