- Lung volumes and capacities
- Residual volume (RV)
- amount of air left in the lungs after a maximal expiration (no change during exercise)
- Inspiratory reserve volume (IRV)
- maximal amount of air forcibly inspired in addition to tidal volume (decreases during exercise)
- Vital capacity (VC)
- maximal amount of air exhaled after a maximal inspiration (TV + IRV + ERV)
- Tidal volume (TV)
- amount of air breathed in or out per breath (increases during exercise)
- Total lung capacity (TV)
- vital capacity + residual volume (TV+IRV+ERV+RV)
- Expiratory reserve volume (ERV)
- maximal amount of air forcibly expired in addition to tidal volume (decreases during exercise)
- Minute ventilation (Ve)
- amount of air that is moved in and out of the lungs in one minute (ml. min-1)
- Ve = frequency of breathing x tidal volume
- Residual volume (RV)
