Abstract
CONTEXT:
Respiratory muscle exercises are used not only in the rehabilitation of respiratory disease patients but also in endurance training for athletes. Respiration involves the back and abdominal muscles. These muscles are one of the elements responsible for posture control, which is integral to injury prevention and physical performance. However, the effects of respiratory muscle exercise on posture remain unclear.
OBJECTIVE:
This study aimed to examine the potential of respiratory muscle exercise for improving posture.
MAIN OUTCOME MEASURES:
The spinal curvature, pulmonary function, and trunk muscle strength were measured for both the groups at baseline and the end of the 4 weeks. The data were compared between the Ex. and Cont. groups with Mann-Whitney U test, pre- and post-intervention within groups with Wilcoxon signed rank-sum test.
RESULTS & CONCLUSION:
The spinal curvature was significantly different within the Ex. group, indicating a decrease in the thoracic (-13.1%, P<0.01) and lumbar (-17.7%, P<0.05) angles. The Ex. group presented with lower thoracic (-8.6%) and lumbar (-20.9%) angles at post-exercise as compared with the Cont. group (P<0.05). With respect to trunk muscle strength, only the trunk flexion strength significantly increased from pre-test to post-test within the Ex. group (P<0.05). For pulmonary function, the forced vital capacity and the forced expiratory volume in 1.0 sec were significantly increased after 4 weeks within Ex. group(P<0.05). Our results suggested that respiratory muscle exercises straightened the spine, leading to good posture control, possibly due to the contraction of abdominal muscles.
