Efficacy of Therapeutic Exercise in Modulating Cancer-Related Fatigue in Women After Breast Cancer Treatment

Introduction: The prevalence of cancer-related fatigue in women treated for breast cancer is about 30% having significant effects in reducing their quality of life. There is evidence of the presence of sleep problems and immune response. Several studies claim that physical exercise is effective during and after treatment of the disease as it improves the quality of life, cardiorespiratory function, physical functioning and symptoms of fatigue although not always found significant differences between intervention groups exercises compared with a control group. Although the results of these studies are promising, generally present methodological biases as small sample size, absence of masking, heterogeneous groups, lack of monitoring short and long term and especially lack of specificity in relation to prescribed exercise ( frequency, intensity, time and type of exercise).

Subjects and methods: A randomized clinical trial, the examiner being blinded unaware of the intervention group to which subjects were assigned. Participants will be randomly assigned to two groups:

An experimental group, where the participants will be treated with Therapeutic Exercise;

And a group where will be done Physical Exercise according their preferences.

Pre-intervention, immediate post-intervention, 3 and 6 months assessments will be made. The selection criteria will be: Adult women treated for breast cancer, completed at least 6 months before, with persistent fatigue. All participants must understand and sign freely Informed Consent.
