Even low levels of leisure-time physical activities are beneficial for adults, whilst doing more vigorous exercise has additional health benefits in terms of reducing mortality. Authors call for the promotion of any amount and intensity of physical activity, to reduce mortality risk in the general population | British Journal of Sports Medicine
Background: Evidence on the role of very low or very high volumes of leisure time physical activity (PA) on the risk of all-cause and cause-specific mortality is limited. We aimed to examine the associations of different levels of leisure time PA with the risk of all-cause, cardiovascular disease (CVD) and cancer-specific mortality.
Methods: Data were from 12 waves of the National Health Interview Surveys (1997–2008) linked to the National Death Index records through 31 December 2011. A total of 88 140 eligible participants aged 40–85 years were included.
Results: Compared with inactive individuals, those performing 10–59 min/week of PA had 18% lower risk of all-cause mortality. Those who reported 1–2 times (150–299 min/week) the recommended level of leisure time PA had 31% reduced risk of all-cause mortality. Importantly, the continued benefits were observed among those performing leisure time PA 10 or more times the recommended minimum level. In addition, there was a larger reduction in all-cause and cause-specific mortality for vigorous vs. moderate intensity PA.
Conclusions: We found that beneficial association between leisure time PA and mortality starts from a low dose. Doing more vigorous exercise could lead to additional health benefits.
