After performing the "hold-relax with agonist contraction" PNF stretch for the hamstrings, which of the following explains the resulting increase in flexibility? I. autogenic inhibition II. stretch inhibition III. reciprocal inhibition IV. crossed-extensor inhibition

Respuesta :

Answer:

Autogenic inhibition and reciprocal inhibition.

Explanation:

PNF (Proprioceptive neuromuscular facilitation) is an effective stretching results in the increase in the body's flexibility. The strengthening, stability and mobility can be maintained by PNF stretch.

Autogenic inhibition and reciprocal inhibition increases the flexibility of the body. These inhibitions inhibit the excitability or the contraction of the stretched muscles and increases flexibility.

Thus, the correct answer is option (I) and (III).
