    Input: PURPOSE The aims of this pilot study were the following : 1 ) to examine patterns of adherence to a brisk walking program in women receiving adjuvant chemotherapy or radiation therapy for newly diagnosed breast cancer using a prospect i ve , r and omized , controlled experimental design ; 2 ) to examine the influence of disease symptoms and treatment side effects on exercise levels ; and 3 ) to suggest methods that may improve future clinical trials of moderate-intensity exercise in similar population s. DESCRIPTION OF STUDY Fifty-two patients with newly diagnosed breast cancer were r and omly assigned to one of two treatment arms : usual care or usual care plus exercise . Those assigned to the exercise group received a st and ardized , self-administered , home-based brisk walking intervention in addition to usual care . Each day subjects completed self-report diary forms that elicited information about activity levels , and the occurrence of symptoms and side effects during cancer treatment . RESULTS Analyses of self-reported daily activity levels revealed a diffusion of treatment effect . Fifty percent of the usual-care group reported maintaining or increasing their physical activity to a moderate-intensity level , while 33 % of the exercise group did not exercise at the prescribed levels . Analyses of self-reported disease symptoms and treatment side effects did not reveal clinical ly meaningful differences between the two groups . CLINICAL IMPLICATION S The results of this study suggest that women who exercised regularly before receiving a breast cancer diagnosis attempted to maintain their exercise programs . Women who lead sedentary lifestyles may benefit from a structured exercise program that includes information and support related to exercise adherence strategies Research suggests that stress‐reduction programs tailored to the cancer setting help patients cope with the effects of treatment and improve their quality of life .  Yoga , an ancient Eastern science , incorporates stress‐reduction techniques that include regulated breathing , visual imagery , and meditation as well as various postures . The authors examined the effects of the  Tibetan yoga ( TY ) practice s of Tsa lung and Trul khor , which incorporate  controlled breathing and visualization , mindfulness techniques  , and low‐impact postures  in patients with lymphoma BACKGROUND AND OBJECTIVES This pilot project assessed the acceptability of a mixed-type , moderate-intensity exercise programme  following breast cancer treatment , and the impact on presence of lymphoedema , fitness , body composition , fatigue , mood and quality of life . METHODS Ten women completed the programme and measures of fitness ( sub-maximal ergometer test ) , body composition ( bio-electrical impedance ) , lympoedema ( bio-electrical impedance and arm circumferences ) , fatigue ( revised Piper Fatigue Scale ) , mood ( Hospital Anxiety and Depression Scale ) , quality of life ( FACT-B ) and general well-being , at baseline , completion of the programme , and 6-week and 3-month follow-up . RESULTS Participation in the programme caused no adverse effect on the presence of lymphoedema . There was a trend towards reduction in fatigue and improved quality of life across the testing phases . Women rated the programme extremely favourably , citing benefits of the support of other women , trained guidance , and the opportunity to experience different types of exercise . CONCLUSIONS A mixed-type , moderate-intensity exercise program in a group format is acceptable to women following breast cancer treatment , with the potential to reduce fatigue and improve quality of life , without exacerbating or precipitating lymphoedema . This pilot work needs to be confirmed in larger r and omised studies PURPOSE The primary purpose of this study was to examine the effect of aerobic exercise on physiological and psychological function in patients rehabilitating from cancer treatment . A second purpose was to evaluate the differential effects of low- and moderate-intensity exercise on these variables . METHODS Eighteen survivors of breast or colon cancer ( 15 female and 3 male , 40 - 65 yr of age ) served as subjects . The subjects were matched by aerobic capacity and scores on a Quality of Life question naire , and then r and omly assigned to a control , low- ( 25 - 35 % heart rate reserve ( HRR ) ) , or a moderate- ( 40 - 50 % HRR ) intensity exercise group . The exercise groups performed lower-body aerobic exercise three times a week for 10 wk . After the exercise training , there were no statistically significant differences between the two exercise groups on any of the physiological variables . Therefore , the exercise groups were combined into one group for the final analysis . RESULTS The results revealed statistically significant increases in aerobic capacity ( P < 0.001 ) and lower-body flexibility ( P = 0.027 ) , a significant decrease in body fat ( P < 0.001 ) , and a significant increase in quality of life ( P < 0.001 ) and a measure of energy ( P = 0.038 ) in the exercise group when compared with the control group . CONCLUSION Low- and moderate-intensity aerobic-exercise programs were equally effective in improving physiological and psychological function in this population of cancer survivors .  Aerobic exercise appears to be a valuable and well-tolerated component of the cancer-rehabilitation process The efficacy of energy conservation and activity management ( ECAM ) for fatigue reduction and maintenance of functional performance has never been evaluated in adults with cancer who are undergoing treatment PURPOSE Self-directed and supervised exercise were compared with usual care in a clinical trial design ed to evaluate the effect of structured exercise on physical functioning and other dimensions of health-related quality of life in women with stages I and II breast cancer . PATIENTS AND METHODS One hundred twenty-three women with stages I and II breast cancer completed baseline evaluations of generic and disease- and site-specific health-related quality of life , aerobic capacity , and body weight . Participants were r and omly allocated to one of three intervention groups : usual care ( control group ) , self-directed exercise , or supervised exercise .  Quality of life , aerobic capacity , and body weight measures were repeated at 26 weeks . The primary outcome was the change in the Short Form-36 physical functioning scale between baseline and 26 weeks . RESULTS Physical functioning in the control group decreased by 4.1 points , whereas it increased by 5.7 points and 2.2 points in the self-directed and supervised exercise groups , respectively ( P = .04 ) . Post hoc analysis showed a moderately large ( and clinical ly important ) difference between the self-directed and control groups ( 9.8 points ; P = .01 ) and a more modest difference between the supervised and control groups ( 6.3 points ; P = .09 ) . No significant differences between groups were observed for changes in quality of life scores . In a secondary analysis of participants stratified by type of adjuvant therapy , supervised exercise improved aerobic capacity ( + 3.5 mL/kg/min ; P = .01 ) and reduced body weight ( -4.8 kg ; P < .05 ) compared with usual care only in participants not receiving chemotherapy . CONCLUSION Physical exercise can blunt some of the negative side effects of breast cancer treatment , including reduced physical functioning .  Self-directed exercise is an effective way to improve physical functioning compared with usual care . In participants not receiving chemotherapy  , supervised exercise may increase aerobic capacity and reduce body weight compared with usual care PURPOSE To determine the effects of breast cancer-specific print material s and step pedometers on  physical activity ( PA ) and quality of life ( QoL ) in breast cancer survivors . PATIENTS AND METHODS Breast cancer survivors ( N = 377 ) were r and omly assigned to receive one of the following : a st and ard public health recommendation for PA , previously developed breast cancer-specific PA print material s , a step pedometer , or a combination of breast cancer-specific print material s and step pedometers . The primary outcome was self-reported moderate/vigorous PA minutes per week . Secondary outcomes were QoL ( Functional Assessment of Cancer Therapy-Breast ) , fatigue , self-reported brisk walking , and objective step counts . Assessment s were conducted at baseline and postintervention ( 12 weeks ) . RESULTS Attrition was 10.3 % ( 39 of 377 ) . On the basis of linear mixed-model analyses , PA increased by 30 minutes/week in the st and ard recommendation group compared with 70 minutes/week in the print material group ( mean difference , 39 minutes/week ; 95 % CI = -10 to 89 ; d = 0.25 ; P = .117 ) , 89 minutes/week in the pedometer group ( mean difference , 59 minutes/week ; 95 % CI , 11 to 108 ; d = 0.38 ; P = .017 ) , and 87 minutes/week in the combined group ( mean difference , 57 minutes/week ; 95 % CI , 8 to 106 ; d = 0.37 ; P = .022 ) . For brisk walking minutes/week , all three intervention groups reported significantly greater increases than the st and ard recommendation group . The combined group also reported significantly improved QoL ( mean difference , 5.8 ; 95 % CI , 2.0 to 9.6 ; d = 0.33 ; P = .003 ) and reduced fatigue ( mean difference , 2.3 ; 95 % CI , 0.0 to 4.7 ; d = 0.25 ; P = .052 ) compared with the st and ard recommendation group . CONCLUSION Breast cancer-specific PA print material s and pedometers may be effective strategies for increasing PA and QoL in breast cancer survivors . A combined approach appears to be optimal . CLINICAL TRIAL REGISTRATION Clinical Trials.gov Identifier PURPOSE Cancer treatment-related fatigue is the most prevalent and distressing symptom of cancer therapy . Interventions to minimize fatigue are needed . The purpose of this study was to examine the relationship between exercise and fatigue over the first three cycles of chemotherapy in women receiving either cyclophosphamide , methotrexate , and fluorouracil ( CMF ) or doxorubicin and cyclophosphamide ( AC ) for breast cancer . METHODS Seventy-two newly diagnosed women with breast cancer were instructed in a home-based moderate-intensity exercise intervention . Measures of functional ability , energy expenditure , and fatigue were obtained at baseline and posttest . Subjects maintained daily records of four types of fatigue , and exercise duration , intensity , and type . RESULTS Exercise significantly reduced all four levels of fatigue ( P < 0.01 ) . As the duration of exercise increased , the intensity of fatigue declined ( P < 0.01 ) . There was a significant carry-over effect of exercise on fatigue , but the effect lasted only 1 d. The level of fatigue at study entry was not associated with number of days of exercise or amount of exercise a woman engaged in . CONCLUSIONS The impact of exercise on fatigue was significant and suggests the effectiveness of a low- to moderate-intensity regular exercise program in maintaining functional ability and reducing fatigue in women with breast cancer receiving chemotherapy BACKGROUND Physical activity provides a number of physical and psychological benefits to cancer survivors , including lessening the impact of detrimental cancer-related symptoms and treatment side-effects ( e.g. fatigue , nausea ) , and improving overall well-being and quality of life . The purpose of the present pilot study was to examine the physical and psychological benefits afforded by a 7-week yoga program for cancer survivors . METHOD Eligible participants ( per-screened with PAR-Q/PAR-MED-X ) were r and omly assigned to either the  intervention ( n=20 ) or control group ( n=18 ) . All participants completed pre- and post-testing assessment s immediately before and after the yoga program , respectively . RESULTS The yoga program participants ( M age=51.18 ( 10.33 ) ; 92 % female ) included primarily breast cancer survivors , on average 55.95 ( 54.39 ) months post-diagnosis . Significant differences between the intervention and the control group at post-intervention were seen only in psychosocial ( i.e. global quality of life , emotional function , and diarrhea ) variables ( all p 's < 0.05 ) . There were also trends for group differences , in the hypothesized directions , for the psychosocial variables of emotional irritability , gastrointestinal symptoms , cognitive disorganization , mood disturbance , tension , depression , and confusion ( all p 's < 0.10 ) . Finally , there were also significant improvements in both the program participants and the controls from pre- to post-intervention on a number of physical fitness variables . CONCLUSIONS These initial findings suggest that yoga has significant potential and should be further explored as a beneficial physical activity option for cancer survivors . Future research might attempt to include a broader range of participants ( e.g. other types of cancer diagnoses , male subjects ) , a larger sample size , and a longer program duration in an RCT AIM Our purpose was to investigate the effect of a relaxation breathing exercise on fatigue in allogenic haemopoietic stem cell transplantation patients . BACKGROUND Exercise is a promising approach in ameliorating the fatigue associated with cancer and its treatment . DESIGN A r and omized design with control , experimental groups being assessed pre- and postintervention . METHODS Thirty-five patients were r and omly selected , with 18 assigned to an exercise group and 17 to a control group .  The exercise intervention lasted for 30 minutes every day for six weeks . It consisted of physical exercise combined with relaxation breathing exercise .  Fatigue was measured by the revised version of the Piper Fatigue Scale . RESULTS The exercise group had a greater decrease in fatigue than the control group . CONCLUSION These findings indicate that a relaxation breathing exercise would improve fatigue in allogenic haemopoietic stem cell transplantation patients .
