Respiration During Exercise
Terms • Ventilation • Respiration • Pulmonary respiration • Cellular respiration
Ventilation • Respiratory Muscles • • Inspiration • Diaphragm (rest and exercise) • External intercostal muscles (exercise) • Others (exercise) Expiration • Internal intercostal muscles (exercise) • Abdominal muscles (exercise) FY I
Structure of the Respiratory System • Conducting Zone • Respiratory Zone • Alveoli
Respiration PO 2 = 100 • PO 2 inside the venous blood = 40 • PO 2 inside the alveoli = 100 • Therefore, O 2 flows from the high pressure (lungs) to the low pressure (blood) • PO 2 inside the arterial blood = 100 PO 2 = 40 PO 2 = 100
Respiration PO 2 = 100 PCO 2 = 40 Pulmonary Respiration Cellular Respiration PO 2 = 40 7
Oxygen Saturation Sea level = 97% Saturation Mount Everest = 48% Saturation

Ventilation & Exercise • Does the pulmonary system limit exercise performance? • Untrained - fatigue of respiratory muscles • Trained - greater than 80% of max and longer than 10 min • Exercise-induced hypoxemia
Training 20 -30% decrease
Training • Do the lungs adapt to exercise training? Respiratory Muscles • Do the respiratory muscles adapt to exercise training? Inspiration Diaphragm (rest and exercise) External intercostal muscles (exercise) Others (exercise) Expiration Internal intercostal muscles (exercise) Abdominal muscles (exercise)
Pulmonary Diseases • Exercise induced asthma • Chronic obstructive lung disease (COPD)
