To examine pelvic stability with and without instruction regarding the voluntary recruitment of the 'powerhouse' muscles during a long stretch exercise on the Pilates Reformer.
Evaluation of the muscle activity and pelvic stability during a Pilates exercise of 12 physically active volunteers. Volunteers performed five repetitions of the long stretch in sets of two, one with and one without instruction regarding the voluntary recruitment of the powerhouse muscles. Electromyography of the external oblique (EO), multifidus (MU), gluteus maximus (GM) and adductor longus (AL) muscles and pelvic angle stability were recorded.
When asked to perform the exercise with instruction regarding the voluntary recruitment of the powerhouse muscles, all muscles were more activated, with the exception of the EO. In the voluntary recruitment situation, lumbopelvic stability, as measured by the coefficient of variation of the pelvic angle, was higher than in instances without instruction. Lumbopelvic stability undergoes changes with and without instruction regarding the voluntary recruitment of the powerhouse muscles when the long stretch exercise is performed on a Reformer.
在普拉提矫正机上进行长时间伸展运动时，研究有无关于主动募集“核心肌群”肌肉的指导情况下的骨盆稳定性。
对12名身体活跃的志愿者进行普拉提运动期间的肌肉活动和骨盆稳定性评估。志愿者以两组为一组进行五次长时间伸展重复动作，一次有关于主动募集核心肌群肌肉的指导，一次没有。记录腹外斜肌（EO）、多裂肌（MU）、臀大肌（GM）和长收肌（AL）的肌电图以及骨盆角度稳定性。
当被要求在有关于主动募集核心肌群肌肉的指导下进行运动时，除腹外斜肌外，所有肌肉的激活程度都更高。在主动募集的情况下，通过骨盆角度变异系数测量的腰骶骨盆稳定性高于没有指导的情况。在矫正机上进行长时间伸展运动时，有无关于主动募集核心肌群肌肉的指导，腰骶骨盆稳定性都会发生变化。
