Respiratory adaptations · Physiology

Endurance training affects breathing during submaximal exercise by:

  1. Increasing ventilation at the same workload
  2. Decreasing ventilation at the same workload
  3. Increasing respiratory rate only
  4. Reducing tidal volume
Show answer and explanation

Correct answer: Decreasing ventilation at the same workload

Training reduces ventilation required for a given workload. This reflects improved metabolic efficiency.
