Exercise intensity and longevity in men : the Harvard Alumni Health Study.
- To examine the independent associations of vigorous (=6 resting metabolic rate [MET] score) and nonvigorous (<6 MET score) physical activity with longevity.
- Prospective cohort study, following up men from 1962 or 1966 through 1988.
Men with a mean age of 46 years reported their physical activities on questionnaires at baseline.
Main Outcome Measure
- All-cause mortality (3728 deaths).
- Total energy expenditure and energy expenditure from vigorous activities, but not energy expenditure from nonvigorous activities, related inversely to mortality.
After adjustment for potential confounders, the relative risks of dying associated with increasing quintiles of total energy expenditure were 1.00 (referent), 0.94,0.95,0.91 and 0.91, respectively (P [trend]<. 05).
Analyses of vigorous and nonvigorous activities were mutually adjusted.
Among men who reported only vigorous activities (259 deaths), we observed decreasing age-standardized mortality rates with increasing activity (P=05) ; among men who reported only non-vigorous activities (380 deaths), no trend was apparent (P=99).
- These data demonstrate a graded inverse relationship between total physical activity and mortality.
Furthermore, vigorous activities but not nonvigorous activities were associated with longevity.
These findings pertain only to allcause mortality ; nonvigorous e.
