Immediate Effects of Postural Restoration Exercises and Breathing on Shoulder and Pelvic Mobility

Prolonged sedentary behavior and habitual poor posture often lead to asymmetrical muscular loading and restricted joint mobility, such as glenohumeral internal rotation deficit (GIRD). Traditional interventions primarily focus on passive, localized stretching. However, the human body functions as an interconnected kinetic chain, where the mobility of distal joints (like the shoulder) is heavily influenced by the axial alignment of the thorax and pelvis, as well as breathing mechanics. This study aims to investigate the immediate effects of Postural Restoration Exercises (PRE)-which uniquely combine specific asymmetrical positioning with prolonged exhalation techniques-on pelvic alignment and shoulder mobility in healthy young adults. Using a dismantling design, participants are assigned to three groups: the Postural Restoration Exercise (PRE) group, the Positional Exercise (PE) group, and the Breathing Exercise (BE) group. By comparing these groups, the study seeks to isolate and clarify whether the restorative benefits stem primarily from limb positioning, breathing mechanics, or the integration of both. The ultimate goal is to provide evidence for a highly efficient, self-administered intervention to improve motor performance and reduce injury risk.
