Research continues to support a link between moderate, regular exercise and a healthy immune system. During moderate exercise immune cells circulate through the body more quickly and are better able to kill bacteria and viruses. After exercise ends, the immune system generally returns to normal within a few hours, but consistent, regular exercise seems to make these changes more long-lasting.
However, there is also evidence that too much intense exercise can reduce immunity. This research is showing that more than 90 minutes of high-intensity endurance exercise can make athletes susceptible to illness for up to 72 hours after the exercise session. Intense exercise seems to cause a temporary decrease in immune system function.
What is used to test the effects of flu on your body:
Your Heart: An electrocardiogram (ECG) is a test that records the electrical activity of the heart. An ECG is used to measure: 1. Any damage to the heart 2. How fast your heart is beating and whether it is beating normally 3. The effects of drugs or devices used to control the heart (such as a pacemaker) 4. The size and position of your heart chambers
Myocarditis refers to inflammation of the heart muscle as a result of a viral illness. In severe cases this inflammation reduces the pumping capacity of the heart
Your Lungs: A lung function tests measure how well the lungs take in and release air and how well they move gases such as oxygen from the atmosphere into the body's circulation.
Blood Pressure: Blood pressure is the force exerted by blood against the walls of the arteries. Blood pressure increases during exercise to ensure sufficient blood is returned to the heart for distribution to the large muscle groups.
PLEASE NOTE! Refrain from participating in any physical activity when you have a fever!
