Poor blood circulation will likely reduce the contraction power of a person’s: myosin, actin, fast twitch fibers, slow twitch fibers

Poor blood circulation will likely reduce the contraction power of a person's myosin.

Explanation:

Myosins are from a diverse family of motor proteins which play a substantial tole in the contraction of muscles as well as other movement related processes in Humans. Their functioning depends on ATP production and they also play role in actin-based movement in organisms.  Moreover, they have important role in production of mechanical energy in body. The poor blood circulation badly affects the contraction of myosin fibres due to decrease in  myosin light chain kinase enzymes which have direct relation with muscle functioning.
