Recent studies have indicated that maximum expiration could be a useful way of performing challenging exercises that include coactivation of the deep and superficial abdominal muscles. However, little is known about the effect of maximum expiration on the activity of the abdominal muscles during lumbar stabilizing exercise.
The purpose of our study was to quantify changes in the activities of the abdominal muscles during side bridge exercise in combination with maximum expiration.
Experimental laboratory study.
The activities of the rectus abdominis (RA), external oblique (EO), and internal oblique (IO) muscles were measured using electromyography in 12 healthy men performing 3 tasks: holding the breath after maximum expiration in the prone position, holding the breath after resting expiration during side bridge exercise, and holding the breath after maximum expiration during side bridge exercise.
Significant increases in the activities of the abdominal muscles (RA, EO, and IO) occurred with maximum expiration when compared with resting expiration during side bridge exercise (P < 0.05).
This is the first study to demonstrate the effect of maximum expiration on abdominal muscle activities during a stabilizing exercise, thus contributing to existing knowledge about therapeutic exercise for alternative core training.
最近的研究表明，最大呼气可能是进行具有挑战性的运动的一种有用方法，这些运动包括深层和浅层腹肌的共同激活。然而，关于最大呼气对腰椎稳定运动期间腹肌活动的影响知之甚少。
我们研究的目的是量化在侧桥运动结合最大呼气时腹肌活动的变化。
实验性实验室研究。
在12名健康男性中，通过肌电图测量腹直肌（RA）、腹外斜肌（EO）和腹内斜肌（IO）的活动，他们执行3项任务：在俯卧位最大呼气后屏气、在侧桥运动期间静息呼气后屏气、在侧桥运动期间最大呼气后屏气。
与侧桥运动期间的静息呼气相比，最大呼气时腹肌（RA、EO和IO）的活动显著增加（P < 0.05）。
这是第一项证明最大呼气对稳定运动期间腹肌活动影响的研究，从而为关于替代性核心训练的治疗性运动的现有知识做出了贡献。
