Prescribing Physical Activity Through Primary Care: Does Activity Intensity Matter?
Abstract Background : Physical activity guidelines recommend engaging in moderate- and vigorous-intensity physical activity to elicit health benefits . Similarly , these higher intensity ranges for activity are typically targeted in healthy living interventions ( ie , exercise prescription ) . Comparatively less attention has been focused on changing lower intensity physical activity ( ie , sedentary activity ) behaviors . The purpose of this study was to explore the effects of prescribing changes to physical activity of various intensities ( ie , sedentary through exercise ) through the primary care setting . Methods : Sixty older adults ( aged 55–75 years ; mean age 63 ± 5 years ) volunteered to participate , and were r and omly assigned to 4 groups : 3 receiving an activity prescription intervention targeting a specific intensity of physical activity ( exercise , sedentary , or both ) , and 1 control group . During the 12-week intervention period participants followed personalized activity programs at home . Basic clinical measures ( anthropometrics , blood pressure , aerobic fitness ) and blood panel for assessing cardiometabolic risk ( glucose , lipid profile ) were conducted at baseline ( week 0 ) and follow-up ( week 12 ) in a primary care office . Results : There were no differences between groups at baseline ( P > 0.05 ) . The intervention changed clinical ( F(5 , 50 ) = 20.458 , P = 0.000 , ηP2 = 0.672 ) and blood panel measures ( F(5 , 50 ) = 4.576 , P = 0.002 , ηP2 = 0.314 ) of cardiometabolic health . Post hoc analyses indicted no differences between groups ( P > 0.05 ) . Conclusion : Physical activity prescription of various intensities through the primary care setting improved cardiometabolic health status . To our knowledge , this is the first report of sedentary behavior prescription ( alone , or combined with exercise ) in primary care . The findings support the ongoing practice of fitness assessment and physical activity prescription for chronic disease management and prevention
