ABSTRACT
OBJECTIVE:
The aims were (i) to assess the effects of a 12-week resistance training program on between-arms volume difference and shoulder-arm disabilities in breast cancer survivors and (ii) to evaluate whether the main risk factors for developing cancer-related lymphedema and shoulder-arm disabilities were associated with the effects of the training program.DESIGN:
Randomized controlled trial.SETTING:
University facilities.PARTICIPANTS:
60 female breast cancer survivors participated. ELIGIBILITY CRITERIA to be a breast cancer survivor, and to have completed surgery, chemotherapy, and/or radiotherapy up to 10 years before recruitment. EXCLUSION CRITERIA metastatic breast cancer, a breast reconstruction intervention planned within 6 months, any absolute contraindication for exercise, to perform more than 300 minutes/week of structured exercise.INTERVENTIONS:
Participants were randomized to an exercise group (12-week resistance training program) or a control group. MAIN OUTCOMEMEASURES:
Between-arms volume difference, shoulder-arm disabilities, and upper-limb muscular strength were evaluated at baseline and at week 12. Treatment-related information was registered from medical history.RESULTS:
No between-group differences were observed on between-arms volume difference (1.207; 95% CI -0.964, 3.377; P=.270) or shoulder-arm disabilities (2.070; 95% CI -4.362, 8.501; P=.521) after the training program. Likewise, there was no association of surgery type, presence of lymph node resection, chemotherapy, radiotherapy, and hormone therapy with the changes in between-arms volume and perceived shoulder-arm disabilities after the intervention. However, a higher increase in upper limb muscular strength was associated with a reduced shoulder-arm disabilities (-0.429; P=.020) in the exercise group.CONCLUSIONS:
The findings suggest that resistance training does not affect between-arms volume difference and shoulder-arm disabilities in female breast cancer survivors. The main risk factors for developing lymphedema were not associated with the effects of the intervention, although a higher increase in upper-limb muscular strength was associated with reduced shoulder-arm disabilities.Palabras clave
