Why doe muscle size does not necessarily correlate with muscle strength?

Question

As the title says. Why does hypertrophy (growing muscle tissue in size) does not correlate with the strength of the individuals training for strength (as in heavy weight lifting, without growing muscle tissue)?

Answer 1

Strength is a function of nerve innervation of motor neurons. The more nerve-motor neuron connections, the more “pulling” that occurs within a muscle. Hypertrophy (hyperplasia) is an increase in the number of muscle cells, these will inherently have some nerve-motor neuron connections, but not in the same density as in muscle groups that are adapted to increase density of these nerve-motor neurons.

Peak Force production (max strength) vs Hypertrophy (muscle size). When one increases, the other will increase but not proportionally.
