Exercise 3 Hours a week Lower Heart Attack Risk Men

Reduced risk of heart attacks in men can be done by way of sport. Just 3 hours a week doing sports, he was able to avoid a heart attack.

Researchers at Harvard School of Public Health found that approximately 38 percent reduced risk of heart attacks in men is caused by the beneficial effects of physical exercise. With physical exercise can raise levels of good cholesterol or high density lipoprotein (HDL) in men.

The results of these studies have been published in the journal Medicine & Science in Sports & Exercise. The study shows 3 hours of vigorous exercise a week can reduce heart attack risk by 22 percent male.

The study has involved 1239 men in the Health Professionals Follow Up Study which provides information on the amount of their weekly exercise. The researchers also analyzed the levels of cholesterol, the study participants, as well as biomarkers of inflammation and insulin sensitivity.

Between 1994 to 2004, 454 men had suffered non-fatal heart attack or dying from coronary heart disease. Some 412 men in the group of men with heart problems compared with a control group of 827 men without heart problems.

Coronary heart disease is narrowing or blockage of coronary arteries. Coronary arteries are the arteries that supply blood to the heart muscle. When blood flow slows, the heart not getting enough oxygen and nutrients.

This usually results in chest pain called angina. When one or more blocked coronary arteries at all, the result is a heart attack, which occurred because there is damage to the heart muscle.

Coronary heart disease was originally caused by a buildup of fat on the inside walls of blood vessels of heart or commonly known as coronary arteries. So over time followed by various processes such as accumulation of connective tissue, perkapuran, blood clotting and others.

This will narrow or clog the blood vessels. So will result in heart muscle in those areas experiencing shortages of blood flow and can cause serious repercussions, such as chest pain (angina pectoris) to myocardial infarction.

Angina pectoris and myocardial infarction commonly known as a heart attack. Heart attacks can cause sudden death.

The results of these studies indicate that risk factors for cardiovascular disease is more common in the group of men with heart problems compared with the control group.

"Men who suffer non-fatal heart attack or dying from coronary heart disease have fewer levels of HDL, and bad cholesterol (LDL) more more, and more likely to have high blood pressure, high cholesterol and diabetes," said study author Andrea Chomistek as reported by the Health

Do not exercise if you're sick of this

Exercise is a great way to boost immunity, but when the body is sick whether you still have to exercise? There are some guidelines you need to know before deciding to exercise when sick.

Regardless of how often you exercise, maybe some people will wonder if allowed to exercise when the body is sick. It actually depends on the type of disease and body condition of each person.

But there are some general guidelines to keep in mind before deciding to exercise when you're sick, as reported by about.com, Thursday (16/11/2011):

1. Fever
If you had a fever then you should stay home and rest. Not only the body is fighting an infection, stay home and rest can prevent disease transmission to others. Usually not difficult to leave the sport when she was a fever because most people are more often sleepy.

2. Cough
When people cough a little bit more complicated to decide whether to exercise or not. If you're only an occasional dry cough, then there is no problem to continue with your exercise routine. However, if the cough is more frequently and interfere with the ability to breathe properly when the heart rate is up, you should consider resting until the cough improves.

3. Heart disease
Sports can not kill except in people with heart disease. If your condition does not fit then do not force yourself to exercise. In people with a history of cardiovascular exercise a forced exercise (not according to the ability of the body) can cause rupture of the layer of fat in the blood vessels that lead to total blockage and cause sudden death.

4. Disease that makes the body weak
The energy levels are one of the best indicators of whether you should exercise or not. If you feel tired then let your body rest and recover before continuing the exercise routine. But if you are just the common cold and still quite powerful, it could not hurt to keep exercising
