title: What do studies of exercise and cardiovascular mortality tell us?
abstract: Studies of exercise and cardiovascular mortality were reviewed to determine whether leisure-time or work activity affects mortality. Twenty-one prospective cohort and 12 rehabilitation case-control studies were reviewed based on epidemiological criteria. Most studies suffered from design deficits.Based on available information, physicians' recommendations about exercise should not include the possibility of increased life expectancy.
