Running is a popular leisure-time physical activity, with many of us taking a regular jog. Iowa State University (Iowa, USA), researchers observe that people who run in their spare time tend to have lower rates of heart-disease related deaths. Duck-chul Lee and colleagues studied 55,137 adults, ages 18 to 100 years (mean age 44 years), surveying the subjects about their physical activities of the past 3 months – including whether they ran (and if so, the speed, duration and frequency). Participants were followed for a mean of 15 years, during which death rates and causes were tracked. The data revealed that people who ran at all were 30% less likely to die during the study period and 45% less likely to die from cardiovascular disease, as compared to the non-runners. Moreover, runners were at a reduced risk of death even if they ran for less than 51 minutes or less than six miles per week, and even if they ran at a pace slower than six miles per hour. Writing that: “Running, even 5 to 10 min/day and at slow speeds <6 miles/h, is associated with markedly reduced risks of death from all causes and cardiovascular disease,” the study authors are hopeful that: “this study may motivate healthy but sedentary individuals to begin and continue running for substantial and attainable mortality benefits.”
Running Deters Disease, Lengthens Lifespan

Regardless of speed or distance, runners tend to have lower rates of heart-disease related deaths u2013 translating to a potential of 3 additional years of lifespan.
