The phrase "no pain, no gain" is often used in regards to exercise. Though in terms of jogging, this may not be the case. In a new study, researchers found that individuals who participate in vigorous jogging have a similar mortality risk as in-active, non-joggers, while light joggers are more likely to live the healthiest and longest.
In Copenhagen, Denmark, Frederiksberg Hospital's Dr. Peter Schnohr, and co-workers disclose their discoveries in the Journal of the American College of Cardiology.
Various examinations have related reduced mortality with physical activity, with some showing that a limited measure of training can have the best benefit. A new study by Medical News Today, states that a daily 20-minute low intensity walk can help lower the risk of early death by 16-30%.
The tie between reduced mortality and lower levels of exercise is proven with this new study, which claims low intensity jogging is most beneficial for decreasing the risk of early death.
Dr. Schnohr and his co-workers examined over 5,000 healthy people that were included in the Copenhagen City Heart Study to get to their findings. Of these, over 1,000 were joggers and just under 4,000 were sedentary non-joggers.
Through 12 years of follow-up, the researchers recorded the subject's jogging, including their jogging pace and the number of hours they jogged..
Jogging more than a few times a week at an intense pace can cause more damage than good. During the the time the subjects were studied, 28 joggers passed away while 128 non-joggers did as well. The team claims that overall, joggers seemed younger, with a lower rate of smoking and diabetes, and had a decrease in body mass index (BMI) and blood pressure.
It was discovered by the researchers that participants who jogged for 1-2.4h/week over the span of 3 days had the least mortality rate. The lower mortality rates were shown among the individuals that jogged at a low intensity pace. The highest mortality rates were located in both the sedentary non-joggers and surprisingly the fast-paced joggers.
The Physical Activity Guidelines for Americans state that adults should engage in either 2.5 hours of moderate-intensity aerobic activity or 1.25 hours of vigorous-intensity aerobic activity every week.
Dr. Schnohr comments saying:
"The U-shaped association between jogging and mortality suggests there may be an upper limit for exercise dosing that is optimal for health benefits. 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. Anything more is not just unnecessary, it may be harmful."
MNT, November 2014 stated a study suggested lightly jogging for at least 30 minutesthree times a week can slow the aging process.
