[Purpose] The purpose of this study was to examine the effects of deep abdominal muscle strengthening exercises on respiratory function and lumbar stability. [Subjects] From among 120 male and female students, 22 whose thoraxes opened no more than 5 cm during inspiration and expiration and whose forced expiratory flow rates were around 300 m/L were recruited. The subjects were randomly divided into an experimental group of eleven, who performed deep abdominal muscle strengthening exercises, and a control group of eleven, who received no particular intervention. [Methods] The subjects were instructed to perform normal breathing in the hook-lying position. They were then directed to hold their breath for ten seconds at the end of inspiration. Ten repetitions of this breathing comprised a set of respiratory training, and a total of five sets were performed by the subjects. [Results] Deep abdominal muscle training was effective at enhancing respiratory function and lumbar stabilization. [Conclusion] The clinical application of deep abdominal muscle strengthening exercises along with lumbar stabilization exercises should be effective for lower back pain patients in need of lumbar stabilization.
[目的] 本研究旨在探讨腹直肌强化训练对呼吸功能及腰椎稳定性的影响。[对象] 从120名男女学生中，招募了22名吸气和呼气时胸廓张开不超过5厘米、用力呼气流量约为300毫升/秒的学生。将受试者随机分为实验组（11人，进行腹直肌强化训练）和对照组（11人，不进行特殊干预）。[方法] 受试者被要求在仰卧屈膝位进行正常呼吸。然后，指导他们在吸气末屏气10秒。这种呼吸重复10次为一组呼吸训练，受试者共进行5组。[结果] 腹直肌训练在增强呼吸功能和腰椎稳定性方面有效。[结论] 腹直肌强化训练与腰椎稳定训练的临床应用，对于需要腰椎稳定的下背痛患者应是有效的。
