Question

What is the type of respiration performed by marathon runners during most of their run?

• A. Aerobic respiration
• B. Anaerobic respiration
• C. Asthmatic respiration
• D. None of the above

Answer 1

The correct option is A

Aerobic respiration

Marathon runners rely on aerobic respiration because it provides a sustained energy release from muscles required for running long distances. If anaerobic respiration occurs, it would quickly cause muscles to cramp up. This means that the runner would not be able to run for long. This is why marathon runners ensure that they run slower than a sprinter and always run at a steady pace.
