Summary

This study aims to investigate randomized controlled trial to evaluate whether reducing sedentary behavior improves recovery in post-cardiac surgery patients. Participants are assigned to either a behavioral intervention that substitutes sitting with light activity or to usual care. Changes in exercise capacity and quality of life are the primary measured outcomes. It is hypothesized that the intervention group will demonstrate superior gains in both physical function and well-being. The results could inform a valuable adjunct to existing cardiac rehabilitation programs.

Detailed description

This randomized controlled trial (RCT) aims to determine the efficacy of a targeted sedentary behavior (SB) modification program as a component of early recovery following cardiac surgery. Participants are randomly allocated to either an intervention group, receiving structured counseling and feedback to replace prolonged sitting with frequent bouts of light-intensity physical activity, or a control group receiving standard postoperative care alone. subjective enhancements in health-related quality of life, assessed via validated questionnaires.The randomized control trial involving 24 patients.The study duration will be 3 months with assesment conducted at baseline,mid and end of intervention.Group A(interventional group recieving Sedantary Behavior protocol+Cardiac Rehab),Group B(Control group recieving only Cardiac Rehab).

Interventions

Type	Name	Description
OTHER	Sedentary Behaviour Modification Protocol	structured intervention designed to reduce the total time spent sitting or lying down (excluding sleeping) and to break up long, uninterrupted periods of inactivity. Effective protocols, often guided by the COM-B model (Capability, Opportunity, Motivation, Behaviour), aim to replace sedentary time with light-intensity physical activity (e.g., walking, standing).
OTHER	Standard Cardiac Rehabilitation	A 3-12 week outpatient, medically supervised program starting shortly after surgery, focusing on monitored exercise (Treadmill), risk factor modification, and education to safely improve heart function. It involves 1-hour sessions 2-3 times a week, combining aerobic training, light strength training, and lifestyle counseling
