    1. Respiration During Exercise

    2. Terms Ventilation Respiration Pulmonary respiration Cellular respiration

    3. Ventilation Respiratory Muscles Inspiration Diaphragm (rest and exercise) External intercostal muscles (exercise) Others (exercise) Expiration Internal intercostal muscles (exercise) Abdominal muscles (exercise)

    5. Structure of the Respiratory System Conducting Zone Respiratory Zone Alveoli

    6. Respiration PO2 inside the venous blood = 40 PO2 inside the alveoli = 100 Therefore, O2 flows from the high pressure (lungs) to the low pressure (blood) PO2 inside the arterial blood = 100

    7. Respiration

    8. Oxygen Saturation

    9. The Pulmonary System & Exercise

    10. Control of Ventilation

    11. Ventilation & Steady State Exercise

    12. Ventilation & Graded Exercise

    13. Ventilation Threshold

    14. Ventilatory & Lactate Thresholds

    15. 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

    16. Training

    17. Training Do the lungs adapt to exercise training? Do the respiratory muscles adapt to exercise training?

    18. Pulmonary Diseases Exercise induced asthma Chronic obstructive lung disease (COPD)
