Lung Volumes

The respiratory system has two main jobs:
  • Deliver oxygen to our muscles
  • Take away the waste product carbon dioxide
  Vital Capacity, Tidal Volume and VO2 Max: These are all measures that feature in sports training and evaluation. Sports coaches and physiotherapists use them to estimate the efficiency of a sportsperson’s respiratory system. Vital Capacity – The greatest amount of air that can be made to pass into and out of the lungs by the most forceful inspiration and expiration. Normally this is about four to five litres. Tidal Volume – The amount of air inspired and expired with each normal breath at rest or during exercise. VO2 Max – The volume of oxygen an athlete can consume per minute while exercising at maximum capacity.
