Abstract Resume

Background:
Yoga is very popular for almost students in school PE course, and flexibility is not only an important factor of learning Yoga but also one of the main resistances for their practices. PNF method is
characterized by increasing the flexibility of muscles without obvious pain, which has immediate and long-term practice effect. This study thinking about rational composed of Yoga course for
university’s normal students by understanding the PNF Yoga relaxing exercise effect, to provide theoretical and practical basis for having better yoga classes.

Methods:
Divided into 2 groups according to their PE class, each group is 50 university’s female students without excessive flexibility. No significant difference in their primary indicators measuring. At the
end of 16 weeks Yoga course, Which is once a week Yoga elective courses include 20 minutes warming up, 55-minute Asana, 15 minutes relaxing activities, Control group(C) ’s relaxation activities still
using supine relaxation but PNF groups’ relaxing activity using a hold-relax-antagonist contraction PNF method to girls’ shoulder muscles and hip-muscle. Gripping stick test shoulders’ flexibility and
Sitting forward bend test hamstring muscle flexibility.

Results:
Using Paired sample t-test, the Results showed both groups’ hamstring muscle flexibility improved through 16-week Yoga course(P<0.01), while shoulders’ flexibility without significant increase
(P>0.05) compared with that 16-week before. Maybe the reason is students’ hip muscles were given more stimulus intensity by Yoga Asana movements in PE course. After different relaxing, PNF groups’
values of gripping stick reduced 5.98cm, significantly improves shoulder flexibility (P<0.01), values of sitting forward bend increased 1.03cm and improves the hamstring flexibility compared with that
before relaxing (P<0.05).
Using independent sample t-test compared PNF and C group after last relaxing at the end of 16 weeks Yoga course , the Results showed PNF groups’ values of gripping stick reduced 4.71cm, PNF groups’
shoulder flexibility was obviously better, but hamstring flexibility without different(P>0.05).It’s consistency with the results before, it can explain due to 16 weeks Yoga Asana movements also
increases flexibility, especially hamstring flexibility, so comparison of PNF group and C group, the former improved their shoulders’ flexibility more obviously.


Conclusions:
The PNF method applied to yoga relaxation activities can improve students’ flexibility immediately; studies may continue to investigate long-term flexibility of PNF relaxation activities for students
in future. Yoga Asana is also increasing their flexibility, so local flexibility increase after PNF is not obvious. In yoga teaching in the future, the teacher should consider the reasonable
arrangement of integrated action, that is doing more comprehensive exercise of main joints and muscle group.
