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 .
Effects of home-based diet and exercise on functional outcomes among older, overweight long-term cancer survivors: RENEW: a randomized controlled trial.
CONTEXT Five-year survival rates for early stage colorectal , breast , and prostate cancer currently exceed 90 % and are increasing . Cancer survivors are at greater risk for second malignancies , other comorbidities , and accelerated functional decline . Lifestyle interventions may provide benefit , but it is unknown whether long-term cancer survivors can modify their lifestyle behaviors sufficiently to improve functional status . OBJECTIVE To determine whether a telephone counseling and mailed print material -based diet and exercise intervention is effective in reorienting functional decline in older , overweight cancer survivors . DESIGN , SETTING , AND PARTICIPANTS R and omized controlled trial of 641 overweight ( body mass index > or = 25 and < 40 ) , long-term ( > or = 5 years ) survivors ( aged 65 - 91 years ) of colorectal , breast , and prostate cancer , who were r and omly assigned to an intervention group ( n = 319 ) or delayed intervention ( control ) group ( n = 322 ) in Canada , the United Kingdom , and 21 US states . Individuals were recruited for the Reach out to Enhance Wellness ( RENEW ) trial from July 1 , 2005 , through May 17 , 2007 . INTERVENTION A 12-month , home-based tailored program of telephone counseling and mailed material s promoting exercise , improved diet quality , and modest weight loss . The control group was wait-listed for 12 months . MAIN OUTCOME MEASURES Change in self-reported physical function on the Short-Form 36 physical function subscale ( score range , 0 - 100 ; a high score indicates better functioning ) from baseline to 12 months was the primary end point . Secondary outcomes included changes in function on the basic and advanced lower extremity function subscales of the Late Life Function and Disability Index ( score range , 0 - 100 ) , physical activity , body mass index , and overall health-related quality of life . RESULTS The mean baseline Short-Form 36 physical function score was 75.7 . At the 12-month follow-up , the mean function scores declined less rapidly in the intervention group ( -2.15 ; 95 % confidence interval [ CI ] , -0.36 to -3.93 ) compared with the control group ( -4.84 ; 95 % CI , -3.04 to -6.63 ) ( P = .03 ) . The mean baseline basic lower extremity function score was 78.2 . The mean changes in basic lower extremity function were 0.34 ( 95 % CI , -0.84 to 1.52 ) in the intervention group compared with -1.89 ( 95 % CI , -0.70 to -3.09 ) in the control group ( P = .005 ) . Physical activity , dietary behaviors , and overall quality of life increased significantly in the intervention group compared with the control group , and weight loss also was greater ( 2.06 kg [ 95 % CI , 1.69 to 2.43 kg ] vs 0.92 kg [ 95 % CI , 0.51 to 1.33 kg ] , respectively ; P < .001 ) . CONCLUSION Among older , long-term survivors of colorectal , breast , and prostate cancer , a diet and exercise intervention reduced the rate of self-reported functional decline compared with no intervention .
