Eight abdominal strengthening exercises were investigated in order to evaluate their ability to promote stabilisation of the lumbar spine. Twenty-three healthy volunteers aged between 18 and 32 participated in the study. During each of the selected exercises, surface electromyography was used to measure the level of motor unit activity in the right upper rectus abdominis, the right lower rectus abdominis, the right oblique abdominis and right lumbar para-vertebral muscles. A formula, based on the relative importance of each muscle in the proposed stability pattern was devised and used to give a single 'stability' score in order to compare each of the eight exercises tested. Results indicated that the exercises which involved applied rotatory resistance to the trunk appeared to activate a more appropriate stability pattern for the lumbar spine.
为评估八种腹部强化练习促进腰椎稳定的能力，对其展开了研究。23名年龄在18至32岁之间的健康志愿者参与了该研究。在每项选定的练习过程中，使用表面肌电图来测量右上腹直肌、右下腹直肌、右腹斜肌和右腰旁肌的运动单位活动水平。基于每种肌肉在提议的稳定模式中的相对重要性设计了一个公式，并用于给出单个“稳定”分数，以便比较所测试的八种练习中的每一种。结果表明，那些对躯干施加旋转阻力的练习似乎能激活更适合腰椎的稳定模式。
