Aerobic literally means "without oxygen." Aerobic activity is high-intensity activity. Group of answer choices True False

Answer: False

Explanation:

Anaerobic means the absence of oxygen while aerobic means the present of oxygen. Anaerobic exercise do not utilize oxygen as energy source, it uses energy from the break down of glucose in the muscles. This exercise is of short length, fast and of high-intensity. A lot of energy is released within a small period of time.

Biologically anaerobic exercise must be fueled using glucose through a process called glycolysis in the muscles cells.

The break down of glucose during high-intensity training without oxygen, producing energy quickly. Because it occurs in the absence of oxygen this process also produces lactate, which is the metabolic fate if glucose in anaerobic condition.

High concentration of lactate is the reason why your muscles get so tired after the energy burst.
