Effect of the Three Different Postures on Motility of Thoracic Cage During Deep Breathing Exercise

There is little research to investigate that which posture could be favorable to lung ventilation in order to induce increasing motility of thoracic cage at the adapted postures after exercise. This study was conducted to investigate which posture could be beneficial to ventilation by measuring the distance of thoracic cage in 3 different postures during deep breathing exercise. Methods : Twenty healthy college students participated in the study. The three-dimensional motion analysing system was used to measure the motion of the thoracic cage in three different postures. After attaching the marker to the specific part of the rib-cage, the normal standing, hand on knee standing, and wall leaning standing were taken for the measurement of rib-cage motility during deep breathing. Results : There was no significant difference in the thoracic cage motility except to marker 5,6. In post- hoc test, the most biggest diameters of the thoracic cage motility in normal standing than that of the other postures (p < 0.05). Conclusion : The results of this study may suggest helpful the normal standing in increasing the left and right diametric motility of the upper thoracic cage when taking deep breathing after intense exercise. However, In previous studies suggested the leaning trunk forward posture could be recommenced for helpful posture to improve ventilation. Hence, The result of this study could be conducted to prove the scientific effects of normal standing in the further study.
