Lighter Jogging May Be Better Than Strenuous Jogging.

TIME (2/3, Park) reports that research published in the Journal of the American College of Cardiology suggests that individuals “who push their bodies too hard may essentially undo the benefit of exercise.”

Bloomberg News (2/3, Ostrow) reports that investigators “looked at 5,048 people in the Copenhagen City Heart Study, a long-term examination of thousands of people that has been the basis for many reports on cardiovascular health.” The investigators “sifted 12 years’ worth of data on 1,098 healthy joggers and 413 healthy but sedentary non-joggers.” The investigators “found those who jogged one to 2.4 hours a week at a slow or average pace with no more than three running days in a week had the best survival rates.”

The Los Angeles Times (2/3, Morin) “Science Now” blog reports that “strenuous joggers – people who ran faster than 7 mph for more than four hours a week; or who ran faster than 7 mph for more than 2.5 hours a week with a frequency of more than three times a week – had a mortality rate that ‘is not statistically different from that of the sedentary group,’ the authors wrote.”
