According to the study, when some elderly with some heart problems do localized muscle activity, despite the amount of exercise is no less than the volume of the systemic activities, but it is more likely to cause heart attacks, so it should be aroused sufficient attention.
In the original, the body?s blood supply is in line with the principle of more pay for more work. So, the larger the part of the body muscle activity is, the greater the degree of vasodilatation of the muscles is, and the more blood they will get. As we all know, the blood flow of the human body are certain, in order to supply the growing muscles need for blood, the blood vessels with no activity must be contracted. This time, when people are doing systemic muscle activity, although there will be a slight rise in blood pressure after the campaign begins, then due to generalized muscle vasodilatation, it will be restored to the original level, such activities neither increase the burden on the heart, but also to achieve the purpose of the exercise. However, when people are doing localized muscle activities, such as the movement of the upper or lower limbs, the active part of the muscle blood vessels will diastole, and most of the inactive muscle blood vessels will contract, causing blood pressure increased significantly, and this will definitely add to the burden on the heart.
In general, under the same amount of output, when people are doing upper limb activities alone, the blood pressure will be higher than the lower limb activities along; but the blood pressure of doing lower limb activities alone is high than systemic activity.
Coupled with the already weak heart and brain function, the patients are vulnerable to appear myocardial infarction. For this, the experts remind that when the elderly or patients with heart disease are doing activities indoor, they are not suitable for doing upper limb activities, such as using dumbbell, or chest-developer to exercise. However, the elderly should carry on some appropriately relaxed and happy systemic activities, so that will not increase the burden of heart, such as dance ballroom dance, doing broadcasting gymnastics, playing taichi and so on.In order to protect your own body and keep health, the elderly should choose the right ways to exercise. Otherwise, it will be unbeneficial to your health, and this even will cause the incidence of some diseases.
