Conclusions The current literature suggests the effectiveness of low-intensity exercise on improved physical and cognitive health for older adults .
It may be a desired intensity level in promoting health among older adults with better compliance , lower risk of injuries , and long-term sustainability
Background It is well known that physical exercise is important to promote physical and cognitive health in older population .
However , inconsistent research findings were shown regarding exercise intensity , particularly on whether low-intensity exercise ( 1.5 metabolic equivalent tasks ( METs ) to 3.0 METs ) can improve physical and cognitive health of older adults .
This systematic review aim ed to fill this research gap .
The objective of this study is to conduct a systematic review of the effectiveness of low-intensity exercise interventions on physical and cognitive health of older adults .
A prospective study of walking as compared with vigorous exercise in the prevention of coronary heart disease in women.
BACKGROUND The role of walking , as compared with vigorous exercise , in the prevention of coronary heart disease remains controversial , and data for women on this topic are sparse . METHODS We prospect ively examined the associations between the score for total physical activity , walking , and vigorous exercise and the incidence of coronary events among 72,488 female nurses who were 40 to 65 years old in 1986 . Participants were free of diagnosed cardiovascular disease or cancer at the time of entry and completed serial detailed question naires about physical activity . During eight years of follow-up , we documented 645 incident coronary events ( nonfatal myocardial infa rct ion or death from coronary disease ) . RESULTS There was a strong , grade d inverse association between physical activity and the risk of coronary events . As compared with women in the lowest quintile group for energy expenditure ( expressed as the metabolic-equivalent [ MET ] score ) , women in increasing quintile groups had age-adjusted relative risks of 0.77 , 0.65 , 0.54 , and 0.46 for coronary events ( P for trend < 0.001 ) . In multivariate analyses , the inverse gradient remained strong ( relative risks , 0.88 , 0.81 , 0.74 , and 0.66 for women in increasing quintile groups as compared with those in the lowest quintile group ; P for trend=0.002 ) . Walking was inversely associated with the risk of coronary events ; women in the highest quintile group for walking , who walked the equivalent of three or more hours per week at a brisk pace , had a multivariate relative risk of 0.65 ( 95 percent confidence interval , 0.47 to 0.91 ) as compared with women who walked infrequently . Regular vigorous exercise ( > or = 6 MET ) was associated with similar risk reductions ( 30 to 40 percent ) . Sedentary women who became active in middle adulthood or later had a lower risk of coronary events than their counterparts who remained sedentary . CONCLUSIONS These prospect i ve data indicate that brisk walking and vigorous exercise are associated with substantial and similar reductions in the incidence of coronary events among women
