Physical activity is recommended for people with stable heart failure ( HF ) , because it is known to improve quality of life and health outcomes .
However , adherence to this recommendation has been poor in many studies .

Evaluation of a 12-week home-based walking intervention for breast cancer survivors
Goals of workTo evaluate a 12-week home-based walking intervention among breast cancer survivors and to quantify changes in  physical activity ( PA ) behaviors , body weight , and body composition in response to the intervention . Patients and methods Breast cancer survivors that were in the posttreatment period were r and omized to intervention ( n=23 ) or wait-list usual care ( n=13 ) .  PA was assessed by self-report , and in a study sub sample ( n=23 ) , by an accelerometer . Intention to treat principles were employed to estimate the intervention effect on PA behaviors , body weight , and body composition . Intervention adherence was calculated as the proportion of exercise sessions completed relative to the number of exercise sessions recommended , as reported each week on walking logs . Main results Thirty-four of 36 women r and omized ( 94 % ) completed the study . Average intervention adherence over 12 weeks was 94 % . Intervention participants reported a significantly greater increase in walking for exercise [ + 11.9 metabolic equivalent (MET)-h/week ] over time than did usual care participants ( + 1.7 MET-h/week , p=0.01 ) . Objective measures of activity also indicated that intervention participants increased their activity levels over time as compared to usual care participants [ i.e. , counts/min/day and steps/day ( p≤0.04 ) ] . No significant changes in body weight or composition were observed . Conclusion We found that a 12-week home-based walking intervention was safe and effective for increasing short-term PA levels in breast cancer survivors . Future studies are needed to assess the ability of brief interventions to facilitate the maintenance of increased activity levels and to produce favorable quality of life and risk factor outcomes
