Rest or exercise when sick?

Most clinical authorities in the area of immunology recommend:
• If one has common cold symptoms (e.g.,
runny nose and sore throat without fever
or general body aches and pains), inte
nsive exercise training may be safely
resumed a few days after the resolution of symptoms.
• Mild-to-moderate exercise (e.g., walking) when sick with the common cold does
not appear to be harmful. In two studies us
ing nasal sprays of a rhinovirus leading
to common cold symptoms, subjects were able to engage in exercise during the
course of the illness without any negative effects on severity of symptoms or
performance capability.
• With a symptom complex of fever, extreme tiredness, muscle aches, and swollen
lymph glands,
2-4 weeks should probably be allowed before resumption of intensive training.
• In general, if the symptoms are from the neck up, moderate exercise is probably
acceptable and, some researchers would even argue, beneficial, while bed rest and
a gradual progression to normal training are recommended when the illness is
systemic. If in doubt as to the type of infectious illness, individuals should consult a
physician.

Should You Exercise When You're Sick?

The flu, as you may have already found out by experience, is much more severe as it is usually accompanied by an array of body aches and fever. Therefore, your body’s immune system is taxed much more by the flu than by the common cold. At this time, bodybuilding training would not only be detrimental to muscle growth, but it would also to your health as well. Remember that while training can help us gain muscle, lose fat, feel good and energetic, it is still a catabolic activity. The body needs to be in good health in order to go from the catabolic state caused by the exercise to an anabolic state of recuperation and muscle growth. So if you have the flu, your body is already fighting a catabolic state caused by the Influenza virus. In this case, weight training would only add more catabolism, which in turn would negatively affect the efficacy of the immune system against the virus, causing you to get sicker. Therefore, absolutely no training if you have the flu. Instead, concentrate on very good nutrition and on drinking large amounts of fluids (water and electrolyte replacement drinks like Gatorade in order to prevent dehydration). Once the flu completely runs its course, you can slowly start up back on your weight training program with lighter weights and not going to failure. Don’t push yourself too hard during this first week.

Should You Exercise With a Cold?

Because exercise may help to boost immune function, it's usually safe to exercise with a cold as long as you listen to your body.

Still, if you exercise with a cold, it's important to listen to your body. Sometimes cold medications such as decongestants can increase your heart rate. In addition, your heart rate is increased with exercise. The combination of exercise and decongestants can cause your heart to pump very hard. You may become short of breath and have difficulty breathing.

If you have asthma and a cold, make sure you talk with your doctor before you exercise. If your asthma symptoms are worse with a cold, you'll need to use caution. Exercising with a cold and asthma may cause increased respiratory symptoms such as coughing, wheezing, and shortness of breath. If you have a fever with a cold, exercise may stress your body even more. That's why it's important to wait a few days to get back to your regular exercise regimen. Working out too hard with a cold could stress your body, causing you to feel worse. This additional stress may hinder your recovery.

Pod prehladom se čovjek osjeća nekako iscrpljeno i zato ne bi baš bilo dobro preforsiravati se, odnosno trčati punim intenzitetom pet km i slično.
Naravno, to nije neka teška bolest da treba ležati cijelo vrijeme.

Da li trenirati/raditi fizičke poslove pod prehladom?
