Exercise has both short-term and long-term effects on the respiratory system. In the short-term, exercise increases respiratory rate, tidal volume, and the rate of gas exchange. In the long-term, it strengthens respiratory muscles, increases respiratory volume, improves lung efficiency, and makes gas exchange more efficient. Regular exercise helps the lungs work harder to increase oxygen intake and remove carbon dioxide, ultimately improving pulmonary function.

3. Introduction
• During rigorous physical activity, such as exercise, the body is
subjected to a lot of stress. However, this stress is beneficial,
and can actually help the body remain healthy.
• Exercise pumps the heart and lungs into prompt action,
which is necessary as these vital organs need to work harder
to cope with the increased demand of oxygen in the body.
• It provides many benefits that help improve the pulmonary
function as well. While some of these benefits are felt
immediately, some take a while to appear.
• Exercise improves the capacity of the lungs to draw in more
oxygen from the air, and provides a host of other benefits as
well.

4. Respiratory System
• Respiratory system controls your
breathing and begins when you
draw in air through your nose or
mouth.
• The air travels through your
windpipe into both of your lungs,
where small air sacs capture
oxygen and distribute it in your
bloodstream through small blood
vessels called capillaries.
• Your diaphragm is the muscle the
controls respiration and contracts
when you inhale.
• Your diaphragm then relaxes,
collapses your chest and forces
out carbon dioxide when you
exhale.

5. Quicker and deeper breathing
respiratory system
• The harder we exercise the deeper and
quicker we will breathe
• Increase in breathing means more oxygen to
the muscles
• If we cant and there does come a point it
results in cramp
• High red blood cell count, therefore high
haemoglobin will allow athletes to cope better

6. Respiratory adaptations to training
• Respiratory system is responsible receiving
Oxygen into the body and dealing with waste
products.
• There is an increase in lung volume
• Vital capacity is increased (max inspiration)
• Tidal volume increases during exercise
• Respiratory muscles get stronger become
more efficient lungs get bigger.
• Pulmonary diffusion becomes more efficient
more O2 can enter the blood.

7. Effect on respiratory system
Short term
• Increases the Respiratory
Rate
• Increases the Tidal Volume
• Increases the Rate of Gas
Exchange
Long term
• Strengthening of the
Respiratory Muscles
• Increases Respiratory
Volume
• Efficient Gaseous Exchange
• Improves Lung Efficiency

8. Conclusion
• The major changes in the respiratory system from
endurance training are an increase in the maximal rate of
pulmonary ventilation,
• Which is the result of increases in both tidal volume and
respiration rate,
• And an increase in pulmonary diffusion at maximal rates
of work, primarily due to increases in pulmonary blood
flow, particularly to the upper regions of the lung.
