Exercise interventions have small clinical benefits on  PA  levels in community-dwelling older adults , with a decline in the observed improvement after six months of the intervention cessation
Exercise is a form of physical activity ( PA ) .
PA is an important marker of health and quality of life in older adults .
The purpose of this study was to conduct a systematic review of the literature to assess the effect of exercise-based interventions on an at least six-month follow up PA measure , and to describe the specific strategies implemented during the intervention to strengthen the sustainability of PA in community-dwelling 65 + year-old adults .
Effect of Physical Activity versus Health Education on Physical Function, Grip Strength and Mobility
BACKGROUND : Physical activity ( PA ) reduces the rate of mobility disability , compared with health education ( HE ) , in at risk older adults . It is important to underst and aspects of performance contributing to this benefit . OBJECTIVE : To evaluate intervention effects on tertiary physical performance outcomes . DESIGN : The Lifestyle Interventions and Independence for Elders ( LIFE ) was a multi‐centered , single‐blind r and omized trial of older adults . SETTING : Eight field centers throughout the United States . PARTICIPANTS : 1635 adults aged 78.9 ± 5.2 years , 67.2 % women at risk for mobility disability ( Short Physical Performance Battery [ SPPB ] < 10 ) . INTERVENTIONS : Moderate PA including walking , resistance and balance training compared with HE consisting of topics relevant to older adults . OUTCOMES : Grip strength , SPPB score and its components ( balance , 4 m gait speed , and chair‐st and s ) , as well as 400 m walking speed . RESULTS : Total SPPB score was higher in PA versus HE across all follow‐up times ( overall P = .04 ) as was the chair‐st and component ( overall P < .001 ) . No intervention effects were observed for balance ( overall P = .12 ) , 4 m gait speed ( overall P = .78 ) , or grip strength ( overall P = .62 ) . However , 400 m walking speed was faster in PA versus HE group ( overall P = < .001 ) . In separate models , 29 % of the rate reduction of major mobility disability in the PA versus HE group was explained by change in SPPB score , while 39 % was explained by change in the chair st and component . CONCLUSION : Lower extremity performance ( SPPB ) was significantly higher in the PA compared with HE group . Changes in chair‐st and score explained a considerable portion of the effect of PA on the reduction of major mobility disability‐consistent with the idea that preserving muscle strength/power may be important for the prevention of major mobility disability
