Endurance training increases the oxidative capacity of a muscle cell.

Question

Quizplus · Accepted Answer

Endurance training involves exercises such as running, cycling, and swimming, which increase the production and utilization of oxygen by muscle cells. This leads to an increase in the number and size of mitochondria, the organelles responsible for aerobic metabolism, thereby enhancing the oxidative capacity of the muscle cell. As a result, endurance athletes can sustain high-intensity efforts for longer periods without getting fatigued.
