The Effect of Round Shoulder Posture Correction on Respiration and Concentration

Purpose: The study aimed to investigate the effect of round shoulder posture correction on respiration and concentration. Methods: A total of 34 college students were included in this study. The participants were divided into three groups: group 1, stretching and stability (n = 12); group 2, stretching and strengthening (n = 12), and group 3, control (10). The exercise interventions were conducted for 4 weeks. Group 1 performed warm-up, stretching, muscle strengthening, and cool down for 30 min. Group 2 performed warm-up, stretching, stabilization, and cool down for 30 min. Group 3 did not receive any intervention. All groups performed round shoulder posture tests, lung capacity tests to determine respiratory function, stroop test, and concentration ability test to determine the concentrations before and after intervention. Results: Significant differences were found in the round shoulder posture on the left between before and after interventions over time (p < 0.05) and between groups (p < 0.05). However, no interaction was observed. The post-hoc test showed that the interventions in group 2 were more effective than those in group 3. A significant difference was noted in the round shoulder posture on the right between before and after intervention over time (p < 0.05). No significant difference and interaction were found between groups. No significant difference was noted in lung capacity. A significant difference in the stroop test (time and number of wrong answers) was found between before and after intervention over time (p < 0.05). No significant difference and interaction were found between the groups. No significant difference was found in the concentration ability test. Conclusion: Our results reveal some evidence that stretching and strengthening exercise causes a decrease in round shoulder posture. However, the intervention period was short and did not allow investigation of the effects on respiratory function and concentration. Continued research on this subject could provide benefits to physiotherapy as it relates to cardiopulmonary treatment.
