How does body temperature affect breathing during slow component replenishment?

• A. When temperature is high, respiratory rates remain high, helping take in more oxygen during recovery.
• B. Breathing rate decreases as temperature rises.
• C. Temperature has no effect on breathing rate.
• D. Temperature rise causes immediate return to pre-exercise respiration.

Answer: (A)

During slow component replenishment after intense exercise, body temperature staying elevated keeps the body's metabolic rate higher. That means more oxygen is needed and more CO2 and heat are produced. The signals from chemoreceptors and thermoreceptors drive the breathing rate up, so ventilation remains high to supply the oxygen needed for recovery processes and to help remove CO2 and heat. Because of this, a higher temperature maintains a higher respiratory rate during recovery rather than dropping back immediately to pre-exercise levels.
