[Purpose] We examined the effects of an abdominal drawing-in bridge exercise using a pressure biofeedback unit on different bases on the thickness of trunk and abdominal muscles, and lumbar stability. [Subjects] Thirty healthy young adults (2 males, 28 females) took part in this study. The subjects were randomly and equally assigned to a stable bridge exercise group and an unstable bridge exercise group. [Methods] The subjects performed bridge exercises using an abdominal drawing-in method on a stable base and on an unstable base, and changes in their abdominal muscle thickness and on the stable and on unstable bases lumbar stability were evaluated. [Results] After the intervention, the stable bridge exercise group showed a statistically significantly increased muscle thickness in the transversus abdominis, and the unstable bridge exercise group showed significantly increased muscle thicknesses of the transversus abdominis and internal obliques in static and dynamic lumbar stability. The unstable bridge exercise group showed significant increase after performing the exercise. [Conclusion] Lumbar stability exercise, with the compensation of the lumbar spine minimized, using an abdominal drawing-in method on an unstable support of base is effective and efforts to prevent the compensation may induce a greater exercise effect.
[目的] 我们研究了使用压力生物反馈装置进行不同支撑面的收腹桥运动对躯干和腹部肌肉厚度以及腰椎稳定性的影响。[对象] 30名健康的年轻成年人（2名男性，28名女性）参与了本研究。受试者被随机且平均分为稳定桥运动组和不稳定桥运动组。[方法] 受试者在稳定支撑面和不稳定支撑面上采用收腹法进行桥运动，并评估其腹部肌肉厚度以及在稳定和不稳定支撑面上的腰椎稳定性变化。[结果] 干预后，稳定桥运动组腹横肌的肌肉厚度有统计学意义的显著增加，不稳定桥运动组在静态和动态腰椎稳定性方面腹横肌和腹内斜肌的肌肉厚度显著增加。不稳定桥运动组在运动后显示出显著增加。[结论] 在不稳定支撑面上采用收腹法进行腰椎稳定性运动，可将腰椎的代偿最小化，是有效的，并且防止代偿的努力可能会产生更大的运动效果。
