Question

Which of the following statements is true of the effects of aerobic exercise

on the muscle?
Aerobic exercise increases mitochondria within cells, making
muscles able to sustain activity for longer periods of time.
Aerobic exercise leads to stronger muscles that sustain activity
for short periods of time.
O Aerobic exercise leads to significantly larger muscles.
Aerobic exercise significantly increases myofibrils within the
muscles.

Answer 1

Aerobic exercise increases mitochondria within cells, allowing muscles to sustain activity for longer periods of time.

Step-by-step explanation:

The correct statement of the effects of aerobic exercise on the muscle is:

Aerobic exercise increases mitochondria within cells, making muscles able to sustain activity for longer periods of time.

During aerobic exercise, such as running or swimming, the body requires a constant supply of energy to fuel the muscles. This energy is produced by the mitochondria, which are the powerhouses of the cell. Regular aerobic exercise increases the number and efficiency of mitochondria within muscle cells, allowing them to produce more energy and sustain activity for longer periods of time.
