American Heart Association has identified that passive lifestyle is one of the five main risk factors that causes heart disease. On the other hand, taking steps to increase physical activities is associated with :
Increase in blood circulation - increase in physical activity creates in demand for more oxygen and nutrients in the body tissues.This need can help increase in the health of the arteries and also encourages growth in new capillary, known as collateral capillary, in the muscles that are involed in exercises. Collateral capillary inproves the overall blood circulation, that aids in improving strength, energy, healing and other functions that are basically in our body system. For example, if you suffer from peripheral artery disease, the collateral capillary in your foot muscle can remove the symptom hence you can walk for a longer distance without feeling the pain. The foot muscle that has become fresh due to exercises encourages blood circulation back to the heart by keeping increase of energy in the veins.
Improve in heart function - Unlike other muscles, the hearts works round the clock. However, exercising helps improve heart efficiency. Frequent physical activity reduces heart beat rates and increases the amount of blood pumped in with every pulse beat. It also helps your lung to deliver oxygen more efficiently to your blood vessels. With a heart that is able to pump more blood, more oxygen will be sent to your muscles and the rest of your body while exercising. All these changes facilitate your heart to work easily.
Reduction in blood pressure - Frequent physical activities have been associated with better long term blood pressure control. If you excessive body weight, or high blood pressure, the effect of exercises to your blood pressure can become more dramatic.
Improvement in blood fat level ( lipid ) - If you worry about your cholesterol level or increase in triglyceride, well... exercise is the answer. Exercise causes reduction in triglyceride, which is a small fat particle in blood. It also increases the high density lipoprotein (HDL), or good cholesterol, and can reduce the amount of low density lipoprotein (LDL), or the bad cholesterol.
Improvement in the health of blood vessels - Reduction in the level of blood fat improves in the formation of plaques in the blood vessels ( atherosclerosis ) and lessens the risks of cardiovascular disease. The decline in blood pressure means less pressure in the inner layer of blood vessels - a thin cell layer called endothelium - and reduce wear and tear which otherwise can encourage plaque formation. Endothelium secretes chemical substance that helps blood vessels to rest or contract. Exercise is known to be able to increase the function of endothelial.
Another factor in the health of blood vessel is inflammation, which can be measured by sensitivity level of high reactive C-protein (hs-CRP) in the blood. There has been rising evidence that inflammation plays an important role in atherosclerosis and hs-CRP is an inflammation symptom. Physical activity can reduce hs-CRP.
Increase in oxygen application ( Maximum usage of oxygen ) - Frequent physical activitiy helps your cells to receive oxygen easier from your blood, reduces burden for the heart and improve your ability to exercise.
Repairing blood sugar level control and insulin - It helps reduces the risk of diabetes type 2, that is associated with problems related to heart disease,
Apart from that, exercises offer other potential benefits, such as tendency to reduce blood clotting, repairing the function of immune systems and reduce the risk of depression.
The Real Benefits
Several small changes to lifestyles such as frequent physical activities can give obvious results to health. Indeed, by doing physical activities for seven hours a week can reduce the risk of early death by 40 percent comparing with someone whose level of weekly physical activities is less than 30 minutes.
