This study aims to investigate the effects of different volumes of combined training on fatigue, neuromuscular variables, morphological, cardiorespiratory capacity, functionality, and quality of life, in breast cancer (BCa) women undergoing primary treatment. Two thirds will be the intervention group that will perform combined training, while the other third will be the control group that will have physiotherapy sessions.
Although chemotherapy and radiation are mainstream treatment modalities, patients will often experience treatment-related side effects such as impairments to the neuromuscular and cardiovascular systems and reduction in quality of life (QoL).To date, numerous positive effects on neuromuscular and aerobic parameters in response to resistance and aerobic training have been reported when both training modalities were simultaneously performed (i.e. combined training - COMB) in BCa patients. However, there is a lack of data regarding the prescription of this modality in BCa patients, as the necessary dose of resistance training for significant improve in fatigue, neuromuscular, and quality of life. In this sense, no previous studies investigate the effect of different volumes of resistance training in BCa patients, providing important informations about the prescription in this clinical population.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Control group | Active Comparator | Patients who are randomized in control group will receive the usual care in their respective hospital. |
|
| Single-set group | Experimental | Patients who are randomized in Single-set (SS) group, will receive 12-week of combined training, twice a week, composed by 10 resistance exercises and 20-25 minutes aerobic exercise at 80-95% of the second ventilatory threshold heart rate in a cycle. One-single set will be performed per exercise at 60-80%1-RM, with 1-1,5min of rest between the exercises. |
|
| Multiple-sets group | Experimental | Patients who are randomized in Multiples-set (MS) group, will receive 12-week of combined training, twice a week, composed by 10 resistance exercises and 20-25 minutes aerobic exercise at 80-95% of the second ventilatory threshold heart rate in a cycle. Regarding resistance exercises, three set will be performed per exercise at 60-80%1-RM, with 1-1,5min of rest between sets and the exercises. |

| Combined training | Other | Resistance exercises performed with different volumes (i.e. one-single set and multiple-sets) and 20-25 minutes of aerobic exercise will be performed twice a week, during 12 weeks. |
| Measure | Description | Time Frame |
|---|---|---|
| Neuromuscular fatigue | Fatigue will be assessed by Fatigue index in isokinetic device. | Changes from baseline are assessed after the intervention (week 13) |
| Subjective fatigue | Fatigue will be assessed by Piper fatigue scale (PFS). The PFS in its current form is composed of 22 numerically scaled, "0" to "10" items (i.e. 0, none fatigue; 10, severe fatigue) that measure four dimensions of subjective fatigue: behavioral/severity (6 items; # 2-7); affective meaning (5 items: # 8-12); sensory (5 items: # 13-17); and cognitive/mood (6 items: # 18-23). These 22 items are used to calculate the four sub-scale/dimensional scores and the total fatigue scores. | Changes from baseline are assessed after the intervention (week 13) |
| Measure | Description | Time Frame |
|---|---|---|
| Body composition | Body composition will be assessed by Dual-energy X-ray absorptiometry | Changes from baseline are assessed after the intervention (week 13) |
| Muscle thickness | Muscle thickness will be assessed by ultrasound images of quadriceps femoris and biceps. |

| Changes from baseline are assessed after the intervention (week 13) |
| Echo intensity | Echo intensity is a grey scale for analyze the image that ranging from 0 (black) to 255 (white), and will be assessed by ultrasound images of quadriceps femoris and biceps. | Changes from baseline are assessed after the intervention (week 13) |
| VO2máx | VO2máx will be assessed by an incremental protocol in a cycle ergometer | Changes from baseline are assessed after the intervention (week 13) |
