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 .
Gait variability and fall risk in community-living older adults: a 1-year prospective study.
OBJECTIVE To test the hypothesis that increased gait variability predicts falls among community-living older adults attending an outpatient clinic . DESIGN Prospect i ve , cohort study . SETTING Three outpatient geriatric clinics . PARTICIPANTS Fifty-two community-living , ambulatory men and women aged > or = 70 years . INTERVENTIONS Not applicable . MAIN OUTCOME MEASURES Subjects walked at a normal pace for up to 6 minutes wearing force-sensitive insoles that measured the gait rhythm on a stride-to-stride basis . Afterward , subjects reported fall status on a weekly basis for 1 year . The primary outcomes were the association between measures of the stride-to-stride fluctuations in gait rhythm and ( 1 ) subsequent falls during a 12-month follow-up period and ( 2 ) potential contributing factors . RESULTS Almost 40 % of the subjects reported falling during the 12-month follow-up period . Stride time variability was 106 + /- 30 ms in subjects who subsequently fell ( n = 20 ) and 49 + /- 4 ms in those who did not experience a fall ( n = 32 ) during the 12-month follow-up period ( p < .04 ) . Logistic regression also showed that stride time variability predicted falls ( p < .05 ) . Stride time variability correlated significantly with multiple factors including strength , balance , gait speed , functional status , and even mental health , but these other measures did not discriminate future fallers from nonfallers . CONCLUSIONS These findings show both the feasibility of obtaining stride-to-stride measures of gait timing in the ambulatory setting and the potential use of gait variability measures in augmenting the prospect i ve evaluation of fall risk in community-living older adults
