Open publisher page 0 citations

Abstract

The impact of PNF stretch time on the joint ROM and the muscle strength was studied. The results indicated that the shoulder joint flexibility was obviously improved with the extension of PNF stretch, while the shoulder joint muscle strength shows downwards tendency. The operation of PNF pull is simple, no need for special venues and equipment. It may be promoted in physical exercise, but it should be noted that excessive stretching is not favorable.
