The heterogeneity in reported effects was reduced in higher quality studies , when physical activity was self-directed with some professional guidance and when there was on-going professional support .
Our review suggests that physical activity interventions have a moderate effect on self reported physical activity and cardio-respiratory fitness , but not on achieving a predetermined level of physical activity .
Due to the clinical and statistical heterogeneity of the studies , only limited conclusions can be drawn about the effectiveness of individual components of the interventions .
BACKGROUND Little is known about the effectiveness of strategies to enable people to achieve an increase in their physical activity .
OBJECTIVES To assess the effects of interventions for promoting physical activity in adults aged 16 years and older , not living in an institution .
A home-based exercise program for nondisabled older adults.
OBJECTIVES This paper describes a videotaped , home-based , strength training program , titled Strong-for-Life and reports on its effectiveness in improving muscle strength , psychological well-being , and health status in a sample of older persons . DESIGN AND SETTING We enrolled 102 nondisabled , community-dwelling older people aged 66 to 87 , identified from the Medicare beneficiary list , into a r and omized , controlled trial . MEASUREMENTS Effectiveness was based on change in isokinetic upper and lower extremity muscle strength , psychologic well-being , and health status . RESULTS Results revealed several statistically significant short-term benefits after 12 to 15 weeks of exercise , especially for men . Younger older adults demonstrated a 10 % improvement in knee extensor strength relative to control subjects . Older male exercisers achieved significant differences relative to controls in perceived anger , tension , and overall social functioning . Male exercisers , in general , achieved significant improvement in perceived vigor . Women did not report psychological benefits following participation in the program . CONCLUSION Study results reveal that the Strong for Life program , design ed to be widely disseminated to the nondisabled older population , has many short-term positive benefits
