Arm Training Alone often Results in Heart Disease

A recent study found that somebody who has heart problems are more likely to cause heart attack when doing localized muscle activity, although the exercise is not larger than systemic activity, it should be got sufficient attention.

In fact, when activity on a unit of muscle becomes greater, the degree of blood vessel expansion at the muscles often becomes greater, then more blood are available. As is known to all, the amount of blood flow in body is certain, in order to supply the blood to the muscles where is taking activities, blood vessels of inactive muscles are bound to shrink. If people take muscle activity on whole body, although the blood pressure will be slightly increased after the beginning of the campaign, it is restored to its original level due to muscle vasodilation, which is neither increased the burden on the heart, but achieve the purposes of exercise. On the contrary, when people take localized muscle activities such as arm or leg movement, most of the inactive muscles of blood vessels are contracted, which causes blood pressure increased significantly and inevitably increases the burden on the heart.

Therefore, suggestions for old men and people who have heart disease from expert are that not to take upper limbs muscle exercise such as using dumbbells and chest exercises in indoor activities, a number of whole body activities such as dancing, doing exercise, playing tai chi and so on are not only be relaxed, but also can’t increase the burden of heart.
