Brief Summary

The aim of this study compares the effects of elastic band and free weights on functional capacity, lung function and quality of life in phase 2 coronary artery bypass grafting patients. Resistance training is vital in cardiac rehabilitation for improving physical function, strength, and independence. These patients typically experience reduced functional capacity and lung function due to post-surgical deconditioning and inactivity, which can also impact quality of life.Determining whether elastic bands or free weights provide greater benefits in these areas may help optimize cardiac rehabilitation protocols by identifying a safe, effective, and accessible approach for improving patient outcomes. This research has the potential to guide evidence-based resistance training in post- coronary artery bypass grafting rehabilitation, ultimately supporting recovery and enhancing quality of life of patients.

Outcome Measures

Primary Outcomes (5)

• Forced Expiratory Volume in 1 Second

  Forced Expiratory Volume in 1 Second (FEV1) is a key lung function test measuring how much air you can forcefully blow out in the first second of a deep breath, indicating how quickly your airways empty.

  12 weeks

• international physical activity questionnaire : Quality of life

  The international physical activity questionnaire is a widely used tool designed to assess physical activity levels among adults. It evaluates various types of activity, including walking, moderateintensity activities, and vigorous-intensity activities, over the past week. The International Physical Activity Questionnaire (IPAQ) scoring involves converting reported activity (walking, moderate, vigorous) into MET-minutes per week by multiplying minutes by MET values (3.3 for walking, 4 for moderate, 8 for vigorous). Scores are then categorized as Low, Moderate, or High, based on specific criteria like achieving ≥3000 MET-min/week (High) or meeting minimum days/minutes for moderate activity (e.g., ≥3 days vigorous or ≥5 days moderate/walking for Moderate), to assess overall activity levels.

  12 week

• 6 Minute Walk Test

  A 6 min walk test is easier, safer to administer, better tolerated and better reflects activity of daily Living than another walk test. The 6-Minute Walk Test (6MWT) scoring primarily focuses on the total distance walked (6MWD) in meters, calculated by counting laps and adding any partial lap, noting rest times. Scores are interpreted using age/sex/height/weight-specific prediction equations (like those from the American Thoracic Society) to compare actual distance to expected normal, with lower scores indicating poorer function, though the longest distance from multiple tests is used to account for learning effects.

  12 weeks

• Forced Vital Capacity

  FVC, or Forced Vital Capacity, is a key measurement in spirometry (lung function tests) that quantifies the total amount of air you can forcefully exhale from your lungs after taking the deepest breath

  12 week

• Peak Expiratory Flow Rate

  Peak Expiratory Flow Rate (PEFR) measures the fastest speed you can forcefully exhale air from your lungs

  12 Week

Study Arms (2)

Dumbell

EXPERIMENTAL

Group A will receive the exercises from dumb bells we will focus on both upper limb and lower limb the total session would be of 20-30 minutes, will be focusing on chest (pectoralis major), back (latissimus dorsi, rhomboids), legs (quadriceps, hamstring, glutes) and core (abdominals, lower back) and after that 5-7 min of cool down. Dyspnea will be measured.

Other: dumbell; Other: thera band

elastic band

EXPERIMENTAL

Group B will receive the exercise form elastic band (TheraBand) for both upper limb and lower limb. Total session time would be 30 minutes will be focusing on chest (pectoralis major), back (latissimus dorsi, rhomboids), legs (quadriceps, hamstring, glutes) and core (abdominals, lower back) 10-12 reps and 1 set in starting progressively increased to 3 reps after that at the end of session 5-7 min cool down and gentle stretching 2 times per week for 12 weeks. Dyspnea should be monitored.
