Moderate exercise improves life expectancy: "Undertaking regular jogging increases the life expectancy of men by 6.2 years and women by 5.6 years, reveals the latest data from the Copenhagen City Heart study ... the study's most recent analysis (unpublished) shows that between one and two-and-a-half hours of jogging per week at a 'slow or average' pace delivers optimum benefits for longevity. ... SThe study, which started 1976, is a prospective cardiovascular population study of around 20,000 men and women aged between 20 to 93 years. The study, which made use of the Copenhagen Population Register, set out to increase knowledge about prevention of cardiovascular disease and stroke. Since then the study, which has resulted in publication of over 750 papers, has expanded to include other diseases ... The investigators have explored the associations for longevity with different forms of exercise and other factors. For the jogging sub study, the mortality of 1,116 male joggers and 762 female joggers was compared to the non joggers in the main study population. All participants were asked to answer questions about the amount of time they spent jogging each week, and to rate their own perceptions of pace (defined as slow, average, and fast). ... The first data was collected between 1976 to 1978, the second from 1981 to 1983, the third from 1991 to 1994, and the fourth from 2001 to 2003. For the analysis participants from all the different data collections were followed using a unique personal identification number in the Danish Central Person Register. ... These numbers have been key to the success of the study since they've allowed us to trace participants wherever they go. ... Results show that in the follow-up period involving a maximum of 35 years, [risk] of death was reduced by 44%."
