During a high-intensity interval training session, a netball player experiences several physiological responses. Which of the following best describes what happens to the player's ventilation rate during the active phases?

  1. Increases to provide more oxygen to working muscles
  2. Decreases to conserve energy for explosive movements
  3. Remains constant regardless of exercise intensity
  4. Cycles between high and low rates regardless of activity level

Consider Option A: Increases to provide more oxygen to working muscles

  • Ventilation rate increases during exercise to supply more oxygen to muscles and remove carbon dioxide.

Other Options:

  • B is incorrect: Ventilation rate does not decrease during exercise; this would limit oxygen delivery.
  • C is incorrect: Ventilation rate varies directly with exercise intensity, not remaining constant.
  • D is incorrect: Ventilation rate responds to physiological demands, not cycling independently.
