Static stretching
During the static stretching training for the calf muscles, the ankle joint is moved into maximal dorsiflexion until the point of discomfort is reached. The ankle joint is then held in this maximal position for 30 s followed by a rest period of 30 s. Afterwards, the procedure is repeated with the knee in flexed position to stretch the soleus muscle.
Proprioceptive neuromuscular facilitation stretching
During the proprioceptive neuromuscular facilitation stretching, the ankle joint is moved into maximal dorsiflexion. While the foot is kept in this position, the child will perform a (sub-) maximal isometric contraction of the plantar flexors against the resistance of their parents. Afterwards, the ankle joint will be moved further into greater dorsiflexion and is held there for the remaining seconds followed by 30 s of rest. Subsequently, the stretch will be applied with the knee flexed.
