OBJECTIVES To assess the effects of interventions to promote exercise behaviour in sedentary people living with and beyond cancer and to address the following questions : Which interventions are most effective in improving aerobic fitness and skeletal muscle strength and endurance ?
What adverse effects are attributed to different exercise interventions ?
Which interventions are most effective in improving exercise behaviour amongst patients with different cancers ?
Which interventions are most likely to promote long-term ( 12 months or longer ) exercise behaviour ?
What frequency of contact with exercise professionals is associated with increased exercise behaviour ?
What theoretical basis is most often associated with increased exercise behaviour ?
What behaviour change techniques are most often associated with increased exercise behaviour ?
Hemoglobin and Aerobic Fitness Changes with Supervised Exercise Training in Breast Cancer Patients Receiving Chemotherapy
Background : Aerobic exercise training ( AET ) is known to increase RBC production ; however , this has not been evaluated in breast cancer patients undergoing adjuvant chemotherapy . The purpose of this study was to examine the changes in hemoglobin ( Hb ) levels in the Supervised Trial of Aerobic versus Resistance Training ( START ) and to determine its association with changes in VO2peak . Methods : Two hundred and forty-two breast cancer patients initiating chemotherapy were r and omized to usual care ( n = 82 ) , resistance exercise ( RET , n = 82 ) , or AET ( n = 78 ) groups for the duration of their chemotherapy ( median , 17 weeks ) . Supervised exercise was thrice weekly based on st and ard AET and RET prescriptions .  Aerobic fitness ( VO2peak ) and Hb concentration were measured at baseline and end of chemotherapy . Results : Regardless of the exercise group , Hb declined over the course of chemotherapy ( 13.4 ± 10.0 to 11.8 ± 11.5 g/dL , P < 0.01 ) . Both AET and RET groups had significant , moderate correlations between the change in VO2peak and Hb ( AET : r = 0.49 , P < 0.001 ; RET : r = 0.39 , P = 0.001 ) . Conclusion : The results indicate that regular exercise does not protect against the decline in Hb associated with chemotherapy in breast cancer patients , but result ed in a stronger association between Hb and VO2peak . Impact : Even with the chemotherapy-induced decline in Hb , breast cancer patients can maintain their aerobic capacity by participating in regular aerobic exercise . Further studies are required to determine safe intensity levels that may stimulate the maintenance of Hb levels in breast cancer patients .
