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 .
Low-intensity exercise as a modifier of physical frailty in older adults.
OBJECTIVE To examine the effects of a 3-month low-intensity exercise program on physical frailty . DESIGN R and omized clinical trial . SETTING Regional tertiary-care hospital and academic medical center with an outpatient rehabilitation fitness center . PARTICIPANTS Eighty-four physically frail older adults ( mean age , 83 + /- 4 yrs ) . INTERVENTION Three-month low-intensity supervised exercise ( n = 48 ) versus unsupervised home-based flexibility activities ( n = 36 ) . MAIN OUTCOME MEASURES Physical performance test , measures of balance , strength , flexibility , coordination , speed of reaction , peripheral sensation . RESULTS Significant improvement was made by the exercise group on our primary indicator of frailty , a physical performance test ( PPT ) ( 29 + /- 4 vs 31 + /- 4 out of a possible 36 points ) , as well as many of the risk factors previously identified as contributors to frailty ; eg , reductions in flexibility , strength , gait speed , and poor balance . Although the home exercise control group showed increases in range of motion , the improvements in flexibility did not translate into improvements in physical performance capacity as assessed by the PPT . CONCLUSIONS Our results suggest that physical frailty is modifiable with a program of modest activities that can be performed by virtually all older adults . They also indicate that exercise programs consisting primarily of flexibility activities are not likely to reverse or attenuate physical frailty . Although results suggest that frailty is modifiable , it is not likely to be eliminated with exercise , and efforts should be directed toward preventing the condition
