骨盆横平面旋转是人体正常运动时的一种能量守恒机制。这种机制的作用是增加步幅，从而降低节奏。有人建议(杜克罗奎特等人)。1968)，在新陈代谢代价高昂的上坡或下坡运动中，骨盆旋转的机制丢失。14名健康的年轻人在跑步机上步行，从20%的下坡到20%的上坡分五个等级进行。测量骨盆在横断面上的旋转度。结果表明，在所研究的等级范围内，上坡和下坡行走对骨盆旋转没有实质性的影响。
Pelvic rotation in the transverse plane is an energy-conserving mechanism employed during normal human locomotion. This mechanism functions to increase stride length and thereby decrease the cadence. It has been suggested (Ducroquet et al. 1968) that the mechanism of pelvic rotation is lost during the metabolically expensive exercise of ascending or descending slopes. Fourteen healthy young adults were walked on a treadmill at five grades from 20% downhill to 20% uphill. Pelvic rotations in the transverse plane were measured. The results show that pelvic rotation is not substantially affected during uphill and downhill walking over the range of grades studied.
