Abstract:

BACKGROUND: Proprioceptive neurmuscular facilitation (PNF) has been used widely in the field of rehabilitation medicine, which has popularity in sports field.
OBJECTIVE: To fully understand the effect of the PNF stretching on the physical flexibility and muscle strength, in order to apply better in the field of sports.
METHODS: Electronic search was used to search reviews and reports concerning the PNF stretching collected by CNKI series databases and PubMed database from 1979 to 2009, and the effects of PNF on physical flexibility and muscle strength was analyzed.
RESULTS AND CONCLUSION: Totally 43 literatures were included in the analysis. Currently, consistent view of PNF stretching on physical flexibility had obtained, namely, PNF can significantly improve the body’s flexibility both of normal and injured patients. However, there were different views on the effect of PNF stretching to muscle strength. Most studies support an increase in the maximal strength and muscular endurance, and increase muscle exercise capacity, but some studies were found no effect or decreased slightly. It is still not comprehensive and in-depth on the application and mechanism of PNF stretching to muscle strength and may have broad prospects on the micro-depth study of muscle fibers.
