When doing PNF stretches, do you maximally contract the target muscle?
Conventionally, maximal contractions have been recommended because it was felt that the Golgi tendon organs (receptors in the tendons of muscle-tendon units) respond only to high forces. In fact, the Golgi tendon organs are sensitive to very low forces, and a contraction of as little as 20%–70% of maximal contraction will suffice (Sharman, Cresswell & Riek 2006). The lower intensity of contractions will help reduce the risk of any type of injury from the PNF stretching.
