Positive outcomes occurred in the short-term from interventions using approaches such as  exercise prescriptions , goal setting , feedback and problem-solving .
However , longer-term maintenance of exercise  was less successful .
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 .
A systematic review was conducted to examine the effectiveness of strategies used to promote exercise adherence in those with HF .
Social cognitive determinants of physical activity in young adults: A prospective structural equation analysis
This study used a prospect i ve design to test a model of the relation between social cognitive variables and physical activity in a sample of 277 university students .  Social support , self-efficacy , outcome expectations , and self-regulation  were measured at baseline and used to predict physical activity 8 weeks later . Results of structural equation modeling indicated a good fit of the social cognitive model to the data . Within the model , self-efficacy had the greatest total effect on physical activity , mediated largely by self-regulation , which directly predicted physical activity . Social support indirectly predicted physical activity through its effect on self-efficacy . Outcome expectations had a small total effect on physical activity , which did not reach significance . The social cognitive model explained 55 % of the variance observed in physical activity
