Brief Summary

Based on clinical experience both physical condition and psychological recovery after surgery are individually variable. Exercise training plays an important part, has been recommended for CABS patients in order to enhance recovery. Regular exercise following CABS has shown that, in addition to the expected improvements in exercise capacity as a result of the surgery itself, patients who participate in cardiac rehabilitation can expect to see additional gains in exercise capacity and risk factor profiles. Exercise training also increases personal self-esteem and self-confidence, can alleviate depression and fear, and increase the sense of well-being. The aim of this study was to examine the effects of supervised aerobic exercise training on pulmonary function, functional capacity, maximal exercise capacity, and anxiety in patients after coronary artery bypass surgery.

Detailed Description

Patients in the training group received supervised aerobic exercise training on the treadmill with the intensity of 60-75% of maximal VO2 for 40-50 minutes, 3 days a week for 8 weeks in a cardiac rehabilitation unit. Work-load was gradually increased during eight-week period. Each session had a five-minute warm-up and cool-down period. Blood pressure and ECG were recorded during training sessions before exercise, at the third minute of each workload, after exercise, and during each minute of the recovery period. In addition, conventional chest physiotherapy and was instructed to continue their daily physical activity program at home patients in this group Patients in the control group received no aerobic exercise training but were asked to continue their chest physiotherapy and daily physical activity program at home.

The same researcher, who was blind to the group allocation, were evaluated all patients for pulmonary functions, respiratory muscle strength and submaximal functional capacity, exercise capacity, and anxiety level initially and after 8 weeks.

Study Groups

Training group

Patients in the training group received supervised aerobic exercise training on the treadmill with the intensity of 60-75% of maximal VO2 for 40-50 minutes, 3 days a week for 8 weeks. Work-load was gradually increased during the eight-week period. In addition, conventional chest physiotherapy and was instructed to continue their daily physical activity program at home patients in this group.

Group Type: EXPERIMENTAL

Chest physiotherapy

Intervention Type: OTHER

The program included diaphragmatic breathing exercises, thoracic expansion exercises, incentive spirometer exercises, and coughing techniques.

Aerobic exercise training

Intervention Type: OTHER

A treadmill was used for aerobic exercise. Training intensity was used at 60-75% of maximal VO2.

Each session had a five-minute warm-up and cool-down period. Blood pressure and ECG were recorded during training sessions before exercise, at the third minute of each workload, after exercise, and during each minute of the recovery period.

Control group

Patients in the control group received no aerobic exercise training but were asked to continue their chest physiotherapy and daily physical activity program at home.

Group Type: ACTIVE_COMPARATOR

Chest physiotherapy

Intervention Type: OTHER

The program included diaphragmatic breathing exercises, thoracic expansion exercises, incentive spirometer exercises, and coughing techniques.
