Light Jogging May Extend Life
There is no single magic bullet that can extend life but exercise has often been touted as one of the keys to good health. But a Danish study, published Feb, 3 2015, has discovered that too much physical activity actually does more harm than good. Instead, researchers found that light jogging is best when it comes to longevity. (Note: Light Jogging is still vigorous exercise not VERY vigorous).
In the study in the Journal of the American College of Cardiology, researchers checked the progress of 5,048 healthy participants for the Copenhagen City Heart Study which lasted 12 years. They isolated 1,098 joggers and 413 but sedentary non-joggers who were all healthy. They also incorporated personal records on hours of jogging, how often they jogged, and the participants’ perception of how fast they jogged.
They discovered that slow to moderate joggers enjoyed dramatically lower mortality rates than fast-paced runners.
The study also concluded that it was best to jog no more than three times per week and between 1.0 and no more than 2.4 hours/week.
The conclusions were obvious to the researchers – fast joggers, who work out for long periods, and jog very regularly were just as likely to die as those who did not jog at all.
“If your goal is to decrease risk of death and improve life expectancy, jogging a few times a week at a moderate pace is a good strategy,” said Dr. Peter Schnohr , a researcher from the Copenhagen City Heart Study. “Anything more is not just unnecessary, it may be harmful.”
“It is important to emphasize that the pace of the slow joggers corresponds to vigorous exercise and strenuous jogging corresponds to very vigorous exercise. When performed for decades, this activity level could pose health risks, especially to the cardiovascular system.”
The findings are consistent with previous research that uncovered similar links between light to moderate exercise and long life, as well as the greater mortality risk linked with vigorous exercise.
