Exercise and Heart Attack
Regular physical activity has long
been regarded as an important component of a healthy lifestyle. Recently, this
impression has been reinforced by new scientific evidence linking regular
physical activity to a wide array of physical and mental health benefits. It
has already been proved that regular physical activity can prevent formation of
atheroma (block) inside your coronary artery. Intermittent bouts of physical
activity, as short as 8 to 10 minutes, totaling 30 minutes or more on most days
provide beneficial health and fitness effects. Physical activity has been
defined as any bodily movement produced by skeletal muscles those results in
energy expenditure. Epidemiologic research has demonstrated protective effects of
varying strength between physical activity and several chronic diseases,
including coronary artery disease (angina/heart attack), hypertension (high
blood pressure), diabetes, osteoporosis (bone thinning), colon cancer and
depressive illness. A midlife increase in physical activity is associated with
a decreased risk of mortality. It has been estimated that as many as 250,000
deaths per year in the United States, approximately 12% of the total, are attributable
to a lack of regular physical activity.
How does exercise prevent heart attack?
· An exercise increase has the blood level of high density
lipoprotein (good cholesterol).
· Reduces blood level of triglyceride, which is a risk factor
of coronary heart disease.
·
Reduces high blood pressure.
·
Enhances fibrinolysis (dissolute the solidified blood
immediately)
·
Reduces blood sugar level in diabetics by increasing insulin
sensitivity.
·
Reduces the adhesiveness of the platelets, so that they can
not unite each other to form thrombosis.
·
Exercise reduces the sensitivity of the heart muscle to
adrenaline and nor adrenaline so, reduces the chance of heart rhythm
irregularity.
