Exercise four days a week to reduce the risk of heart disease

Need to exercise at least four days a week to prevent headache associated with the heart. It is said in a new study that the heart may become fresh again in the US.
This new study found that it is not possible to keep all the arteries fresh in body exercises two to three days a week. Requires at least four days. If you can do five days to do the best work.
Researchers say that any type of physical exercise reduces the risk of cardiovascular disease.
But it is possible to refresh the heart, arteries and veins by taking necessary exercise at the appropriate age.
After this research on 100 people of the sixty-year, the results were published in the Journal of Physiology.
There are several arteries that play a role in spreading blood throughout the body and re-extracting blood in the heart.
The shape of these arteries is like a tube. As the age progresses, they become obscene. Besides, due to chaotic and unhealthy living conditions, the fat covering the artery begins to fall.
Several studies in the United States have found that in the course of two to three days (30 minutes) exercises, the mid-sized arteries that provide blood on the head and neck, are refreshing.
But during the exercise of four to five days a week, with the middle arteries, the main arteries supply blood in the chest and stomach, they are also refreshing.
However, this study did not take into account the issues of diet, education and social status of the people. It is said that these factors also play a role in the recovery of the body.
Dr. Benjamin Levine of the Institute of Exercise and Environmental Medicine, in Dallas, USA, who led the study said, "We now realize that due to the proper exercise, the problem of heart and blood vessels can be changed."
But he said, waiting for 70 years is too late. 'It is not possible to change heart conditions at that age.'
