| Abstract | Purpose : In this study, we aimed to measure how respiratory muscle activity changes as posture changes. We also aimed to measure the inspiratory sternocleidomastoid (SCM) and upper trapezius (UT) muscle activities as well as expiratory rectus abdominis (RA) and oblique abdominis (OA) muscle activities in healthy male and female university students in their twenties. Methods : Using the percentage of reference voluntary contraction (% RVC) with electromyography, we measured the SCM, UT, RA, and OA muscle activities in 16 healthy male and female university students in their 20s according to position change and breather tool use. Results : We found that the average value of inspiratory and expiratory muscle activities by posture was highest when using the breather tool. When using the tool with 10-mm and 2-mm straws for standard breathing at rest in the sitting position, a statistically significant increase in SCM, UT, and OA activities occurred (p < 0.05). For standard breathing at rest in the supine position, a statistically significant increase in SCM, RA, and OA activities occurred (p < 0.05). Conclusion : In clinical application, it may be better to use a respiratory muscle-strengthening tool to increase the activity of inspiratory and expiratory muscles. | ||
