The most important thing to do to keep your lungs healthy is to look after them. Smoking will affect your ability to undertake physical activity and reach your true potential. If you quit smoking, you are likely to be able to exercise for longer as early as two weeks after your last cigarette. People who follow high-intensity training regimes, or who regularly train in certain environments, may be at risk of developing exercise-induced asthma, or a condition known as bronchial hyperresponsiveness in which the airways become blocked after exercise.
If take bronchodilators, you should normally take these 10 minutes before you exercise to prevent exercise-induced bronchoconstriction. Your doctor can give you advice on this. Scientists believe this is caused by harmful substances in the environment in which they are training, such as chlorine in a swimming pool, or cold dry air on a ski slope.
Endurance athletes have the potential to inhale more harmful substances into their lungs, as they are exposed to these conditions for longer periods of time. It is important that you are aware of the symptoms associated with lung problems, such as cough, shortness of breath or fatigue, and that you see your doctor about them as soon as possible.
When you visit the doctor, you may be asked to take a spirometry test. This tests your breathing and can help in the diagnosis of lung problems. You will be asked to breathe into a device that measures the amount of air in your lungs and how fast you can breathe out. Our spirometry factsheet provides more information on the test. You may also be asked to take an exercise test to measure your limitations. People with long-term lung conditions can help improve their symptoms through regular exercise.
If you have a long-term lung condition, the thought of becoming quickly out of breath can be daunting and you may not feel motivated to exercise.
It can be tempting to avoid exercise because you think it will make you breathless, but if you do less activity you become less fit and daily activities will become even harder. It is best to ask the guidance of a doctor or physiotherapist before you begin exercising, to ensure that your exercise plans are in line with your capacity and are safe. All exercise programmes must be built up over time to allow the body to adapt. It's important that you exercise at your own pace.
If you reach a stage where you are too breathless to talk, then slow down the pace or if necessary take a short pause. The more you do, the more you will be able to do! Intermittent exercises can also help you to deal with the shortness of breath. In this case you alternate brief exercise, lasting 1—2 minutes, with moments of rest or slower exercise. If you have COPD, you will have damaged airways.
Provide oxygen O 2 to the tissues of body via the lungs. Eliminate carbon dioxide CO 2 from the tissues of the body via the lungs.
As with the cardiovascular system heart, blood and blood vessels greater demand is placed on these key functions with certain types of exercise.
As exercise commences pulmonary ventilation breathing increases in direct proportion to the intensity and metabolic needs of the exercise. This is shown on the adjacent graph. If the exercise is intense, breathing rates may increase from a typical resting rate of 15 breaths per minute up to 40 — 50 breaths per minute. The most commonly used measure of respiratory function with exercise is known as VO 2 volume of oxygen uptake.
VO 2 refers to the amount of oxygen taken up and used by the body. This is due to an increasing reliance on oxygen to help provide energy as exercise continues.
As the intensity of exercise continues to increase a person reaches a maximum point above which oxygen consumption will not increase any further. This point is known as VO2 max and is shown on the following graph.
EPOC stands for 'Excess Post-exercise Oxygen Consumption', and relates to the bodies need to keep consuming oxygen at a greater than resting rate once exercise has finished to make up for an oxygen 'debt' that is created when exercise commences.
To investigate the effects of exercise on breathing, record the rate of breathing for a few minutes when the person is at rest. After they do some exercise, record their rate of breathing every minute until it returns to the normal resting value.
The pH of the blood is normally 7. She also works as a certified Pilates instructor. Your breathing rate increases during exercise. Video of the Day.
Tip Your respiratory rate during exercise increases to allow more oxygen to reach your muscles and to expel the carbon dioxide waste. Respiration in Exercise. Increased Oxygen Demand. Carbon Dioxide Removal. Body Temperature Regulation. Change in Hormone Levels. Lung Problems and Exercise. Warning While you may notice an increased respiratory rate while exercising, you should not experience shortness of breath or chest pain.
