Dietary supplements and fatigue in patients with breast cancer: a systematic review.

Purpose: Cancer-related fatigue (CRF) is defined as a distressing, persistent, and subjective sense of physical or emotional and/or cognitive exhaustion. The treatment of CRF includes pharmacological and non-pharmacological therapies; dietary strategies with promising results have also been used. This study aimed to identify dietary supplements that improve fatigue in patients with breast cancer.

Effect of exercise on pain and functional capacity in breast cancer patients.

Purpose: To assess the influence of combined training on pain, fatigue, maximal oxygen uptake (VO max), body mass index (BMI), flexibility, and strength in patients with breast cancer.

Methods: A controlled pilot study with 28 patients undergoing chemotherapy, radiation therapy, and clinical observation in a renowned cancer treatment center; the patients were aged from 30 to 59 years old and were not engaged in physical training for three months previously. The Study Group (SG) underwent 12 weeks of training, including three 60-min sessions of aerobic exercise and resistance training, and two sessions of flexibility training per week; each flexibility exercise lasted 20 s and was performed in sets of three repetitions.

Effect of exercise training and detraining in autonomic modulation and cardiorespiratory fitness in breast cancer survivors.

Background: Breast cancer is one of the leading causes of death worldwide. Heart rate variability (HRV) has attracted scientific community attention in different pathologies, becoming thus an ultimate importance tool in both clinical and research setting, being a good predictor of cardiac events and mortality risk and also used in physical exercise and sports in general. The aim of the present study was to evaluate 12 weeks of exercise training and six weeks of detraining in cardiorespiratory capacity, and autonomic modulation in breast cancer patients.
