Quizplus · Accepted Answer

Aerobic exercise such as jogging increases myoglobin (to store oxygen in muscles), the number of mitochondria in skeletal muscle cells (to increase energy production), the enzymes involved in energy utilization (to enhance energy metabolism), and the density of capillaries (to improve oxygen delivery to muscles). Therefore, all of the above options are correct.
