Effectiveness of physical activity on cardiorespiratory fitness and health-related quality of life in young and middle-aged cancer patients shortly after chemotherapy.
PURPOSE To evaluate the effectiveness of a supervised home-based flexible training program on cardiorespiratory fitness ( CRF ) , mental distress , and health-related quality of life ( HRQOL ) parameters in young and middle-aged cancer patients shortly after curative chemotherapy . PATIENTS AND METHODS One hundred eleven patients age 18 to 50 years who had received chemotherapy for lymphomas or breast , gynecologic , or testicular cancer completed the trial . These patients were r and omly allocated to either an intervention group ( n = 59 ) , which underwent a 14-week training program , or a control group ( n = 52 ) that received st and ard care . Primary outcome was change in CRF , as determined by Astr and -Rhyming indirect bicycle ergometer test ( maximum oxygen uptake [ VO(2max ) ] ) , between baseline ( T0 ) and follow-up ( T1 ) . Secondary outcomes were mental distress , as assessed by the Hospital Anxiety and Depression Scale , and HRQOL , as assessed by the European Organisation for Research and Treatment of Cancer Core Quality of Life Question naire . Two-way analysis of covariance was used to analyze changes from T0 to T1 . RESULTS VO(2max ) increased by 6.4 mL/kg(-1)/min(-1 ) in patients in the intervention group and by 3.1 mL/kg(-1)/min(-1 ) in patients in the control group ( P < .01 ) . The fatigue score decreased by 17.0 points in the control group compared with only 5.8 points in the intervention group ( P < .01 ) . There were no intergroup differences in mental distress or HRQOL . CONCLUSION A supervised , home-based , flexible training program has significant effect on CRF in young and middle-aged cancer patients shortly after curative chemotherapy , but it has no favorable effect on patients ' experience of fatigue , mental distress , or HRQOL
