Exercise Training in Patients After Bypass Surgery
Condition: Coronary Artery Bypass Surgery
Study type: Interventional

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.

Intervention description(s): The program included diaphragmatic breathing exercises, thoracic expansion exercises, incentive spirometer exercises, and coughing techniques.; 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.
