The impact of posture correction bands on the respiratory function of healthy adults in their twenties: The difference between men and women

Introduction: Recently, interest in posture correction has increased in Korea owing to increased smartphone usage. However, there have been no studies to evaluate the impact of wearing a posture correction band with an abdominal band on breathing and respiratory function. Materials and Methods: A total of 32 healthy adults, consisting of 16 men (mean age: 23.19 +/- 2.88) and 16 women (mean age: 19.69 +/- 1.49) participated in this study. Pulmonary function tests were conducted before and after wearing posture correction bands. Results: In all the participants, forced vital capacity decreased significantly (P < .05) after wearing a posture correction band. The forced expiratory volume in 1 second and maximal inspiratory pressure decreased slightly (P > .05). The maximal expiratory pressure (MEP) and peak cough flow (PCF) increased slightly (P > .05). When respiratory functions were monitored separately in men and women after wearing a posture correction band, forced vital capacity and forced expiratory volume in 1 second were significantly reduced in men (P < .05). In women, MEP and PCF increased significantly (P < .05). Conclusions: In this study, we confirmed that the posture correction band had an effect on respiratory function. Lung capacity was statistically significantly reduced but was not clinically significant. In addition, in the case of women, it was confirmed that the abdominal band improved the MEP and PCF.
