An endurance runner wants to increase VO₂ max but cannot train at altitude. Which technology best replicates these conditions?

  1. Respiratory muscle trainers with adjustable resistance settings
  2. Hypoxic training masks with oxygen concentration controls
  3. High-output fans creating wind resistance during treadmill running
  4. Wearable devices that restrict breathing rate during intervals

\(B\)

Show Worked Solution
  • B is correct: Hypoxic training masks replicate low-oxygen environments, similar to altitude, promoting adaptations such as increased red blood cell production and improved VO₂ max.

Other options:

  • A is incorrect: Respiratory muscle trainers strengthen breathing muscles but do not reduce oxygen availability like altitude conditions.
  • C is incorrect: Fans create airflow and resistance but do not alter oxygen concentration.
  • D is incorrect: Wearables that restrict breathing rate affect rhythm, not oxygen levels in inspired air.
