tends to increase your heart rate as well as your breathing which aid in giving energy to your muscles as well as fresh oxygen through the rest of your body through your bloodstream. The capacity of your lungs also increases as you work out though only by small increments. As you perform various cardio workouts such as swimming, running, and other intense exercise regimens, your heart will be pumping more while the rest of your body coordinate with one another to provide ample supply of oxygen throughout your body.

How Exercising Affects Your Lungs

Working out regularly tones the lungs and heart which help in improving your pulmonary system’s capacity. Aside from this, regular exercising also means improving on the range of motion that your muscles and joints can do which is beneficial to your overall health. What other effects can exercise do to your lungs?

Increase in Breath Rate

Your respiratory rate increases significantly when you exercise which usually occurs before any changes to the carbon dioxide and oxygen levels in your blood due to working out your muscles. Experts believe that changes in the respiratory rate signify a learned response by the body anticipating the need of more oxygen whenever you work out. And because of this, an adult’s respiratory rate can increase up to 40 to 50 breaths per minute with a resting rate at 10 to 15 breaths.

Blood Flow Changes

The blood that is being pumped by the heart increases whenever you work out and since the blood goes through the lungs, there is also an increase in the pulmonary blood flow which can travel to lung areas that don’t really get enough blood flowing through them. When you combine changes in your blood flow with increased respiratory rate as well as sizes of your breaths, oxygen that is coming from the lungs will be diffused properly throughout the entire body allowing your muscles to perform better.

Increase in Breath Sizes


Aside from increase in respiratory rate, the size of your breaths will be changed as well. Since your body needs more oxygen, you will need to take deeper breaths to fill your lungs with air to be distributed to the rest of your body. Combine this with increase in heart rate then your breath size will increase three fold.

Less Fatigue

Working out doesn’t really have any effect to your lungs at rest. However, the more you exercise the better the function of your heart and muscles which can aid your lungs to produce more oxygen that will be directed to the rest of your body causing you to feel less tired than before. Aerobic exercises, when done regularly, can have positive effects on the function of your lungs and heart. If you really want to boost your overall health, a 20 to 40 minutes worth of cardio exercises can have significant effects on your lung capacity. However, make sure that you consult your doctor first before you do any fitness regimen to ensure that your body can handle the stress that you will put it through.
