When horses trot, metabolic Cost of Transport is independent of speed. At the optimum speeds within each gate, metabolic Cost of Transport is independent of speed. These data show that Horses have specific adaptations for walking, trotting, and galloping. Metabolic Rate is constant, regardless of speed To travel a distance of 10 miles, it is most energetically efficient for a horse to walk. Metabolic Cost of Transport increases with increases in running speed.

Muscle Action

A change in the body or a bodily organ as a result of its functioning is referred to as an action. Muscle action can be defined as the specific movement of a bodily part generated by the contraction of a muscle. The muscle proteins actin and myosin are the important contractile proteins involved in muscle action. Muscle contraction, in addition to movement, serves several other important functions in the body, including posture, heat generation, and joint stability. Muscle contraction maintains posture, which includes standing and sitting.
