NCT03314168

Brief Summary

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.

Outcome Measures

Primary Outcomes (2)

  • 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)

Secondary Outcomes (12)

  • Body composition

    Changes from baseline are assessed after the intervention (week 13)

  • Muscle thickness

    Changes from baseline are assessed after the intervention (week 13)

  • Echo intensity

    Changes from baseline are assessed after the intervention (week 13)

  • VO2máx

    Changes from baseline are assessed after the intervention (week 13)

  • Knee extension muscle strength

    Changes from baseline are assessed after the intervention (week 13)

  • +7 more secondary outcomes

Study Arms (3)

Control group

ACTIVE COMPARATOR

Patients who are randomized in control group will receive the usual care in their respective hospital.

Other: Control group

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.

Other: Combined training

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.

Other: Combined training

Interventions

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.

Also known as: Concurrent training
Multiple-sets groupSingle-set group

The usual care will be recommended to avoid systematic physical exercise for 3 months and will receive general clinical recommendations such as nutritional intake and lifestyle issues in their respective hospital.

Control group
