Final answer:
The ability of a concentric muscle action to produce force increases as the velocity of the action increases.
Step-by-step explanation:
The ability of a concentric muscle action to produce force increases as the velocity of the action increases. When the velocity increases, more myofibers within the muscle receive action potentials from the controlling neuron, leading to a greater force production. Additionally, increasing the frequency of action potentials can further increase force production by flooding the tropomyosin with calcium.
