Physical Activity Outcomes of CHAMPS II
A Physical Activity Promotion Program for Older Adults
Stewart et alAbstract
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 randomized 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 randomized 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 settings.
