Good morning everybody.  Many people have heart ailment specially those who are in the age of 40 and above.  Exercise is the best thing to do.

 

Investing in your heart through regular exercise is certain to give back everything you’ve put into it. 

 

You may neither really care about firm, sexy abs, nor would you care about increasing your muscle power. But there’s certainly one muscle you simply cannot ignore: your heart muscle.

 

Daily physical inactivity or lack of exercise was one of the nine risk factors responsible for 90% of first heart attacks among the 30,000 respondents spread across 52 countries in the Interheart study. Among heart attack survivors who regularly exercised, 90% were more likely to be alive seven years after their heart attack compared to those who remained inactive.  Exercise is,  a worthwhile investment, whether one has had, or has not yet had, a heart attack.

 

The protective effect of exercise was found by investigators to be due to the production of a substance called vascular endothelial growth factor (VEGF) that encourages new blood vessels to grow to supply muscle fibers. These muscle fibers are then able to switch from what is known as anaerobic metabolism (one that uses sugar for energy) to aerobic metabolism (one that needs oxygen to work through the breakdown of fats for energy).
