The effect of PNF stretching on the flexibility quality of rhythmic gymnastics students and its experimental analysis

Rui Zhou, Wenmao Yu

PNF stretching, playing an important role in developing the rhythmic gymnastics teaching in colleges, is a vital means to fully improve the flexibility quality of students. From the students’ development perspective, PNF stretching significantly impacts on the ability of muscle groups against external force, improving the students’ flexibility quality. PNF stretching not only lays a solid foundation for the balance development of students’ flexibility quality, but also provides strong protection of restraining the development of non-dominant flexibility quality. The teaching characteristic of PNF stretching is that the external force can assist to get a better effect of stretching. On the whole process, the increasing communication between students makes the flexibility quality training more interesting, which helps the enhancement of muscle flexibility of students.
