Key result
Postnatal changes in the contractile properties of skeletal muscles were independent of the changes in the duration of after-hyperpolarization of the innervating motoneurones.

Challenges assumed coupling in neuromuscular maturation; leaves open independent regulatory mechanisms for future study.
Huizar et al. (1975) studied this question. Postnatal development (age) was evaluated on Isometric contractions and properties of motoneurones (axonal conduction velocity, duration of after-hyperpolarization). Postnatal changes in the contractile properties of skeletal muscles were independent of the changes in the duration of after-hyperpolarization of the innervating motoneurones.
