About this trial
This study investigates the effect of combined aerobic and resistance training using resistance bands on diaphragmatic excursion and pulmonary function (FVC, FEV₁, PEF) in post-CABG patients undergoing phase II cardiac rehabilitation.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Patients post-CABG surgery maximum 12 weeks after the procedure
Age 40-65 years
Visual and hearing health
Ready to participate in research and sign informed consent.
Disqualifiers
Blood pressure greater than 160 mmHg for systolic and diastolic blood pressure greater than 100 mmHg
Patients with contraindications to aerobic and resistance training, such as fractures that limit movement.
Patients undergoing other therapies that may affect diaphragmatic muscle measurement results, such as electrical diaphragmatic stimulation.
Trial design
Single group
Treatments tested in this trial
Combination of aerobic training (treadmill walking) and resistance training
Other interventionCombination of aerobic training (treadmill walking) and resistance training using resistance bands for deltoid, biceps, triceps, and quadriceps muscles. Conducted twice weekly for 6 weeks (12 sessions). Tools include treadmill and theraband loop bands.

Trial outcomes
Primary outcomes
Diaphragm Excursion (cm)
The vertical movement of the diaphragm during the respiratory cycle shows the function and mobility of the diaphragm in the process of pulmonary ventilation. The data obtained is expressed in cm. Measured via ultrasound.
Secondary outcomes
Forced Vital Capacity (FVC)
Lung function Forced Vital Capacity (FVC) is commonly assessed through spirometry and measured in liters (L) FVC: This measures the total volume of air that can be forcibly exhaled after a full inhalation. FVC values less than 80% of the predicted value are indicative of restrictive respiratory impairments, where the lungs cannot fully expand. FVC values equal to or greater than 80% are considered normal.
Forced Expiratory Volume in one second (FEV1)
Lung function Forced Expiratory Volume in one second (FEV1) is commonly assessed through spirometry and measured in liters (L) FEV1: This represents the air volume a person can forcefully exhale in the first second of a breath.
Peak Expiratory Flow (PEF)
Peak Expiratory Flow (PEF) is a spirometric parameter that measures the maximum airflow achieved at the beginning of a forced expiration, expressed in liters per second or minute. It reflects the function of the large airways and expiratory muscle strength. PEF interpretation is based on the percentage of predicted values according to age, sex, and height: ≥80% is considered normal, 60-79% indicates a mild reduction, 40-59% moderate reduction, and \<40% signifies a severe reduction.
