The first study included 71,893 adults without cardiovascular disease or cancer. The median participant age was 62.5 years old, and just over half (56%) were female. Study authors measured weekly levels of vigorous activity and the frequency of exercise bouts lasting two minutes or less. This was a long-term study; subjects were tracked for an average of 6.9 years.
Then, associations between volume and frequency of vigorous activity with death (all-cause, heart disease, and cancer) and incidence of heart disease and cancer after excluding events occurring in the first year were analyzed by researchers. Sure enough, as both the volume and frequency of vigorous activity increased, risk of all five considered adverse outcomes declined. ...
[S]ubjects who didn’t exercise vigorously at all had a four percent risk of dying within five years. That risk was cut in half (2%) with less than 10 minutes of weekly vigorous activity. Death risk fell to one percent with 60 minutes or more.
When compared to two minutes of intense exercise per week, 15 minutes of vigorous exercise was associated with an 18 percent lower death risk and a 15 percent lower risk of cardiovascular disease. Meanwhile, 12 minutes was linked to a 17 percent lower risk of cancer.
Generally, the more exercise the better. For example, roughly 53 minutes of physical activity on a weekly basis was associated with a 36% lower risk of death from any cause.
