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 .
Physical activity outcomes of CHAMPS II: a physical activity promotion program for older adults.
BACKGROUND Despite well-known benefits of physical activity for older adults , about two thirds are underactive . Community-based programs are needed to facilitate increased physical activity . We examine the effectiveness of CHAMPS II , an inclusive , choice-based physical activity promotion program to increase lifetime physical activity levels of seniors . CHAMPS guided participants to choose activities that took into account their health , preferences , and abilities . It offered information on ways for them to exercise safely , motivate themselves , overcome barriers , and develop a balanced exercise regimen . METHODS A 1-year r and omized controlled trial was conducted with physically underactive seniors in a multispecialty group practice . Changes in self-reported physical activity by group were evaluated using ANCOVA , controlling for age and sex . RESULTS Of 173 r and omized subjects , 164 ( 95 % ) completed the trial . Subjects were aged 65 to 90 years ( M = 74 , SD = 6 ) ; 66 % were female . The intervention group increased estimated caloric expenditure by 487 calories/week in moderate ( or greater ) intensity activities ( MET > /= 3.0 ; p < .001 ) and by 687 calories/week in physical activities of any intensity ( p < .001 ) . Control group changes were negligible . Between-group analyses found that the changes were significantly different in both measures ( p values < .05 ) . Overweight persons especially benefited from this program . The program was as effective for women , older adults ( 75 + ) , and those who did not set aside time to exercise at baseline . CONCLUSIONS The program led to meaningful physical activity increases . Individually tailored programs to encourage lifestyle changes in seniors may be effective and applicable to health care and community setting
