Exercise's short-term impacts The respiratory system would experience three times the usual rate of breathing, five times the normal rate of air taken in or out with each breath, increased blood flow to and through the lungs, and enhanced oxygen absorption. All of these adaptations help athletes perform at their best during exercise.
The long-term effects Exercise has been shown to reduce the risk of developing chronic obstructive pulmonary disease (COPD) and asthma. Regular exercise is also thought to be helpful for people who have COPD or asthma because it reduces the amount of medication needed to control those conditions.
Who are at risk from exercise-induced asthma/bronchospasm? People who experience exercise-induced asthma/bronchospasm are likely to benefit from knowledge about the condition and its treatment. Factors that may increase your risk include having other health problems such as heart disease or lung diseases such as bronchitis or emphysema. Also, people who smoke are more likely to experience asthma symptoms when exercising.
What are the symptoms of exercise-induced asthma/bronchospasm? The most common symptom of exercise-induced asthma/bronchospasm is difficulty breathing. Other symptoms include coughing, chest tightness, pain, and increased temperature due to sweating. These symptoms should go away after you stop exercising.
Exercise has a short-term influence on the respiratory system by increasing respiratory rate. Even little amounts of ventilation a rise in tidal volume and deflation time of the lungs. The heart is also affected by exercise: it must work harder to pump blood through the body during exercise, so it increases its rate. The nervous system is also involved in the response to exercise: muscles around the airways tighten up, reducing their capacity for collapse which prevents air from flowing into and out of your lungs.
The long-term effects of the respiratory system include increased risk of developing asthma and chronic obstructive pulmonary disease (COPD). Exercise can also lead to new problems for patients who already have lung disease. For example, people with asthma may experience increased symptoms as well as increased need for medication or even an attack after exercise. Those with COPD may find that their symptoms get worse as they try to exercise more often than before they became ill.
Why is it important to keep breathing evenly during exercise? If you breathe in quickly when exercising hard or holding your breath, you put yourself at risk of collapsing your lungs. This is very dangerous because you will not be able to breathe if you do this for a long period of time.
Exercise's impact on the respiratory system Because the muscles work harder during exercise, the body utilizes more oxygen and creates more carbon dioxide. To meet this increased demand, the body responds by breathing deeper and more frequently in order to take in the necessary oxygen. This increase in breathing leads to a corresponding rise in heart rate and blood pressure at which point your body will trigger your brain to signal you that it needs more oxygen. If the exercise is continued long enough, this rising blood pressure and heart rate will fall back down to normal after stopping exercise.
The more vigorously one exercises, the faster these rates rise. Therefore, athletes who compete at the highest levels of endurance athletics have respiratory systems that are under considerable stress. In fact, research shows that elite athletes have shorter breath lengths and smaller lung capacity values than non-athletes do. However, their lungs are well developed with greater surface area for gas exchange to occur compared to non-athletes.
Respiratory problems due to excessive training or competition There are several diseases and conditions that can cause problems with the respiratory system. Some of the most common include asthma, bronchitis, emphysema, and cystic fibrosis. All of these disorders can lead to increased airway resistance, reduced lung elasticity, decreased muscle mass, and reduced airflow.
The ventilatory response to exercise is increased ventilation, and because this is not a feedback system, the increase in ventilation occurs at the same time as or slightly before the start of activity. Hypertension lowers the respiratory rate whereas hypotension raises it. Age may also lower the respiratory rate.
The primary mechanism by which exercise affects the ventilatory response is increased metabolic demand; however, other factors are involved as well. The autonomic nervous system plays a major role in regulating the ventilatory response to exercise. Exercise increases activity of both the sympathetic and parasympathetic branches of the autonomic nervous system. The increased activity of the sympathetic branch results in increased secretion of epinephrine and norepinephrine which cause increased breathing rate and tidal volume. The increased activity of the parasympathetic branch causes decreased breathing rate and tidal volume.
Other factors that may influence the ventilatory response include changes in blood pH, pCO2, and HCO3- due to exercise, and these can all have an effect on the efficiency with which oxygen is transported to working muscles. Changes in body temperature due to exercise may also play a role. Increased temperature has been shown to decrease the half-life of oxygen bound to hemoglobin resulting in greater availability for use by working muscles.
Exercise decreases the ventilatory response primarily through increased activity of the autonomic nervous system.
Tidal volume increases during activity as the depth of breathing increases, as does the rate of breathing. This causes the body to absorb more oxygen and expel more carbon dioxide. The increased blood flow to muscles during activity also helps remove toxic substances such as lactic acid from the muscle cells.
The major effect of exercise on vital capacity is an increase in it. During maximum effort, vital capacity can be twice its resting value. After the exercise is over, your capacity returns to its original size.
Vital capacity is the maximum amount of air that can be breathed into or out of the lungs in one breath. It is measured by asking the patient to exhale as completely as possible and then measure the distance that he or she can breathe out. This is expressed in inches or millimeters.
The normal adult male lung capacity is 5-1/4 inches at rest and 10-1/2 inches after exercise, while the female lung capacity is 3-1/4 inches at rest and 7-1/2 inches after exercise. As you can see, there is a lot of room for improvement! But even so, this shows how important it is to get some form of physical activity every day. It is very useful for keeping our lungs healthy and preventing them from aging prematurely.

The short-term effects of exercise on the respiratory system include a rapid increase in respiration rate, deeper breathing, and increased blood oxygen content. The lungs also benefit from exercise by getting more air into them and therefore flushing out mucus and other debris. Exercise is also known to reduce the risk of developing chronic obstructive pulmonary disease (COPD).
The short-term effects of exercise on the gastrointestinal system include increased digestion and absorption of food. The liver also benefits from exercise with increased blood flow causing it to release stored glycogen (blood sugar) for use by other parts of the body.
The short-term effects of exercise on the immune system include increasing numbers of white blood cells which fight infection and improving how the body responds to infections.
The short-term effects of exercise on the nervous system include improved brain function. When you exercise regularly your brain produces more dopamine which helps relieve depression. It also increases the amount of serotonin available to those who suffer from anxiety or panic attacks.
