Comparative study of static, dynamic, and proprioceptive neuromuscular facilitation stretching techniques on flexibility.

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.
