Question

Exceptions to the size principle exist during the performance of high intensity and short duration exercise. This recruitment of fast motor units before activation of slow fibers can be achieved by_____________.

Answer 1

Answer:

Inhibiting the activation of slow motor units

Explanation:

Inhibiting the activation of slow motor unita can lead to greater effects such as muscle resistance and series compliance to shortening in the course of sub-maximal contractions. Thus, in line with the size principles, the activation of the slow motor units comes first and then the faster ones are recruited with increase in demand, and this may likely not pose any mechanical paradox.
