Some physical activity is better than none

It is well known that fitness promoting physical activity is good for the health of you heart. But an important question is how much physical activity is good enough. If you cant find time to have rigorous schedules, is there any good if you do some exercise than none? Jacob Sattelmair and colleagues have evaluated this in a report published online ahead of print in the prestigious cardiology journal Circulation {Dose Response Between Physical Activity and Risk of Coronary Heart Disease: A Meta-Analysis. Circulation. 2011 Aug 1. [Epub ahead of print]}. After evaluated about three thousand and two hundred studies addressing this aspect since 1995, they included thirty three good quality studies. Nine of these studies had information on quantitative estimates of leisure time physical activity. Those who engaged in one hundred and fifty minutes per week of moderate intensity leisure time activity had a fourteen percent lower risk of coronary heart disease. If it was three hundred minutes, the risk reduction was twenty percent. There was a modest further reduction at higher levels of physical activity. Those who had lower than the minimum recommended one hundred and fifty minutes per week of physical activity also had significantly lower risk of coronary heart disease than those who did not. This report supports that concept that some physical activity is better than none and additional benefits occur with more physical activity. So what are you waiting for? Start on that the fitness path which suits you!
