63 college women served as subjects in this 7-wk. study examining the effects of static, dynamic, and proprioceptive neuromuscular facilitating stretching techniques on the flexibility of the hamstring-gastrocnemius muscles. Subjects were assigned to one of the 3 treatment groups and received treatment 3 days a week. A pretest, a midtest (after 11 treatment days), and a posttest (after 21 treatment days) were administered. Analysis of group and test effects was accomplished by using a 3 X 3 factorial design with the group factor nested and the test factor crossed. Post hoc analysis indicated that all scores significantly improved from pretest to posttest. The findings indicated all 3 methods of flexibility training produced significant improvements when pretest and posttest mean scores were compared.
63名大学女生参与了这项为期7周的研究，该研究旨在检验静态、动态和本体感觉神经肌肉促进伸展技术对腘绳肌-腓肠肌灵活性的影响。受试者被分配到3个治疗组中的一组，每周接受3天治疗。进行了一次预测试、一次中期测试（在治疗11天后）和一次后测试（在治疗21天后）。通过使用3×3析因设计来完成对组间和测试效果的分析，其中组因素嵌套，测试因素交叉。事后分析表明，从预测试到后测试，所有分数都有显著提高。研究结果表明，当比较预测试和后测试的平均分数时，所有3种灵活性训练方法都产生了显著改善。
