No significant difference in pulmonary function was observed between the two groups .
However , 6MWD and VO2 peak were significantly improved after exercise training .
Conclusion Preoperative exercise training may reduce PPCs for lung cancer patients .
Rehabilitation exercise strengthens muscle capacity , but does not improve impaired pulmonary function , which emphasizes the possible mechanism of the protocol design
Objectives This meta- analysis aim ed to demonstrate the impact of preoperative exercise therapy on surgical outcomes in patients with lung cancer and COPD .
Pulmonary function and muscle capacity were investigated to explore their potential links with outcome improvements after exercise .
High-intensity training following lung cancer surgery: a randomised controlled trial
Background Many patients with lung cancer are deconditioned with poor physical fitness . Lung resection reduces physical fitness further , impairing the patient 's ability to function in daily life . Methods We conducted a single-blind r and omised controlled trial of high-intensity endurance and strength training ( 60 min , three times a week , 20 weeks ) , starting 5–7 weeks after surgery . The control group received st and ard postoperative care . The primary outcome was the change in peak oxygen uptake measured directly during walking until exhaustion . Other outcomes included changes in pulmonary function , muscular strength by one-repetition maximum ( 1RM ) , total muscle mass measured by dual energy X-ray absorptiometry , daily physical functioning and quality of life ( QoL ) . Results The intention-to-treat analysis of the 61 r and omised patients showed that the exercise group had a greater increase in peak oxygen uptake ( 3.4 mL/kg/min between-group difference , p=0.002 ) , carbon monoxide transfer factor ( Tlco ) ( 5.2 % predicted , p=0.007 ) , 1RM leg press ( 29.5 kg , p<0.001 ) , chair st and ( 2.1 times p<0.001 ) , stair run ( 4.3 steps , p=0.002 ) and total muscle mass ( 1.36 kg , p=0.012 ) compared with the controls . The mean±SD QoL ( SF-36 ) physical component summary score was 51.8±5.5 and 43.3±11.3 ( p=0.006 ) , and the mental component summary score was 55.5±5.3 and 46.6±14.0 ( p=0.015 ) in the exercise and control groups , respectively . Conclusions In patients recently operated for lung cancer , high-intensity endurance and strength training was well tolerated and induced clinical ly significant improvements in peak oxygen uptake , Tlco , muscular strength , total muscle mass , functional fitness and QoL. This study may provide a basis for exercise therapy after lung cancer surgery . Trial registration number NCT01748981
