Which of the following is NOT a guideline for PNF stretching?
A. For each muscle group, complete only 1 set to avoid overstretching.

B. Leave 48 hours between PNF stretching routines.

C. Communicate well when stretching with a partner.

D. You should hold the isometric contraction for 6-10 seconds, and the passive stretch for 10-30 seconds.

The answer is C- it is not necessary

Explanation:

Neurophysiological hypothesis: Inhibition of stretch reflex and increased GTO activity

Viscoelastic hypothesis: Increased elastic and viscous deformation and viscoelastic stress relaxation

Enhanced stretch tolerance: analgesic effect of stretching

so we know the answer cannot be c because no insect or animal starts as an adult

the answer is a. a swimming larvae

because since they are sea animals they automatticaly have to know how to swim they cannot just sink to the bottom

sorry if this is the incorrect answer.
