[Purpose] This study analyzed the activities of the back and hip muscles during Pilates exercises conducted in a prone position. [Subjects] The subjects were 18 healthy women volunteers who had practiced at a Pilates center for more than three months. [Methods] The subjects performed three Pilates exercises. To examine muscle activity during the exercises, 8-channel surface electromyography (Noraxon USA, Inc., Scottsdale, AZ) was used. The surface electrodes were attached to the bilateral latissimus dorsi muscle, multifidus muscle, gluteus maximus, and semitendinous muscle. Three Pilates back exercises were compared: (1) double leg kick (DLK), (2) swimming (SW), and (3) leg beat (LB). Electrical muscle activation was normalized to maximal voluntary isometric contraction. Repeated measures analysis of variance was performed to assess the differences in activation levels among the exercises. [Results] The activity of the multifidus muscle was significantly high for the SW (52.3±11.0, 50.9±9.8) and LB exercises(51.8±12.8, 48.3±13.9) and the activity of the semitendinosus muscle was higher for the LB exercise (49.2±8.7, 52.9±9.3) than for the DLK and SW exercises. [Conclusion] These results may provide basic material for when Pilates exercises are performed in a prone position and may be useful information on clinical Pilates for rehabilitation programs.
[目的] 本研究分析了在俯卧位进行普拉提练习时背部和臀部肌肉的活动情况。[对象] 对象为18名在普拉提中心练习超过三个月的健康女性志愿者。[方法] 受试者进行三项普拉提练习。为检查练习过程中的肌肉活动，使用了8通道表面肌电图（美国诺拉松公司，亚利桑那州斯科茨代尔）。表面电极附着于双侧背阔肌、多裂肌、臀大肌和半腱肌。比较了三项普拉提背部练习：（1）双腿踢（DLK）、（2）游泳（SW）和（3）腿部拍打（LB）。将肌肉电激活水平标准化为最大自主等长收缩。进行重复测量方差分析以评估各练习之间激活水平的差异。[结果] 多裂肌在SW（52.3±11.0，50.9±9.8）和LB练习（51.8±12.8，48.3±13.9）中的活动显著较高，半腱肌在LB练习（49.2±8.7，52.9±9.3）中的活动高于DLK和SW练习。[结论] 这些结果可为俯卧位进行普拉提练习提供基础资料，可能是临床普拉提康复计划的有用信息。
