호흡방법에 따른 전방머리자세의 호흡기능 변화량 비교

Comparison of Respiratory Function Changes of the Forward Head Posture according to the Breathing Methods

Purpose : The purpose of this study was to compare the effects of breathing exercise on the respiratory functions among the breathing methods in the forward head posture. Method : A total of thirty male and female adults in their 20s who showed forward head posture in the overall body posture measurement system participated in this study. Each subject were divided into three groups. The experimental group A(n=10), Experimental group B(n=10) and Experimental group C(n=10) participated in respectively diaphragm, abdominal expansion, and abdominal drawing-in method, three times per week for 4 weeks. Respiratory function was measured using a spirometer. Result : After 4 weeks, Forced vital capacity, Forced expiratory volume 1, and Forced expiratory volume 1/Forced vital capacity were significantly increased in a three group and abdominal expansion maneuver group was highest. But there was no significant difference among the breathing methods. Conclusion : All of breathing methods affects on function of respiration. In particular, abdominal expansion maneuver influenced in a respiratory function. We recommend a abdominal expansion maneuver to improve a respiratory function in a forward head posture.
