Although running is a popular leisure-time physical
activity, little is known about the long-term effects of running on
mortality. The dose-response relations between running, as well as the
change in running behaviors over time, and mortality remain uncertain.
Objectives
We
examined the associations of running with all-cause and cardiovascular
mortality risks in 55,137 adults, 18 to 100 years of age (mean age 44
years).
Methods
Running was assessed on a medical history questionnaire by leisure-time activity.
Results
During
a mean follow-up of 15 years, 3,413 all-cause and 1,217 cardiovascular
deaths occurred. Approximately 24% of adults participated in running in
this population. Compared with nonrunners, runners had 30% and 45% lower
adjusted risks of all-cause and cardiovascular mortality, respectively,
with a 3-year life expectancy benefit. In dose-response analyses, the
mortality benefits in runners were similar across quintiles of running
time, distance, frequency, amount, and speed, compared with nonrunners.
Weekly running even <51 min, <6 miles, 1 to 2 times, <506
metabolic equivalent-minutes, or <6 miles/h was sufficient to reduce
risk of mortality, compared with not running. In the analyses of change
in running behaviors and mortality, persistent runners had the most
significant benefits, with 29% and 50% lower risks of all-cause and
cardiovascular mortality, respectively, compared with never-runners.
Conclusions
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. This study may motivate healthy but sedentary individuals to
begin and continue running for substantial and attainable mortality
benefits.
Comments:
If you transfer these results into the treatment of patients, it may well be questioned if the patient's contiuned and regular imput into physical work-outs can result in a quicker healing time.
