We can say that diet and physical fitness are influenced by the processes of cellular respiration because there is an association between the initial stores of muscle glycogen and the duration of the effort.
<h3>What is Muscle Glycogen?</h3>
Muscle glycogen decreases in a semilogarithmic manner as a function of time, but the concentration of this substrate does not reach zero, which suggests the participation of other fatigue mechanisms in the interruption of prolonged exercise.
In this type of activity, glycogen depletion first occurs in slow-twitch fibers, followed by depletion in fast-twitch fibers. The decrease in the rate of muscle glycogen utilization is synchronously linked to the increase in fat metabolism.
With this information, we can conclude that diet and physical fitness are influenced by cellular respiration processes.
