About this study
Official title: Effects of Combined Training on Quality of Life, Neuromuscular and Cardiorespiratory Parameters in Patients Who Have Completed the Primary Treatment for Breast Cancer: a Randomized Clinical Trial
The aim of the present study is analyze the effects of combined training program (resistance and aerobics) in comparison with a non-training group on quality of life, as well as on neuromuscular and cardiorespiratory parameters in breast cancer patients in stages one to three who have finished their treatment, such as surgery, chemotherapy and radiotherapy. Therefore, 42 women will be randomly divided into two groups: combined training group and control group. The subjects of the combined training group will undergo the intervention three times a week for eight weeks. The combined group will carry out both resistance and aerobic exercises in the same session. The resistance training will be comprised by ten exercises which will alternate body segments with maximum repetitions in the first set and the lower limit of the repetitions interval in the next sets. Along the training, the number of series will be increased whereas the number of repetitions will be decreased. The intensity of the aerobic exercises will be based on the percentage of the heart rate of the anaerobic threshold on the first weeks and on the speed of the anaerobic and aerobic threshold on the last weeks. Before and after the intervention, there will be evaluation of maximal dynamic strength of knee extensors and elbow flexors, maximum voluntary isometric contraction of knee extensors, maximum muscular activity of vastus lateralis and rectus femoris, muscle thickness of knee extensors, peak oxygen uptake and ventilatory threshold, quality of life and cancer-related fatigue. Data will be analyzed by Generalized Estimating Equations (GEE) and Bonferroni's post-hoc (α=0,05), including both protocol and intention to treat.
Read the detailed description
According to the World Health Organization, breast cancer is the most common one among women, both in developed and developing countries. It accounts for 23% of all breast cancer cases worldwide whereas, in Brazil, it represents 25% of new cases per year. However, its mortality rate has increasingly decreased due to advances in screening protocols, diagnoses and treatment in the last decades. Even so, breast cancer and its treatment might cause psychological and physiological side effects that can affect patients' quality of life.
There is evidence that increase in physical activity generates important physical and psychological benefits to patients with cancer. Studies with breast cancer survivors have shown that the fact that the patients become physically active after the diagnosis leads to a 24-67% decrease in total death risk and 50-53% decrease in death related to breast cancer, by comparison with sedentary patients.
Reviews, systematic reviews and metaanalysis of studies that investigated the effects of interventions with physical exercise programs on health outcomes in breast cancer survivors showed the benefits brought to these patients by exercise. However, these reviews have also called the attention of the scientific community regarding the need to standardize measures of outcomes and intervention methods of evaluation since variations found in the studies make it difficult to reach definite conclusions. Furthermore, type, frequency, intensity and duration of exercise sessions to reach beneficial effects on important health parameters for breast cancer have not been well established yet. Therefore, this study aims at analyzing the effects of combined training program (resistance and aerobics), in comparison with a non-training group, on quality of life, as well as on neuromuscular and cardiorespiratory parameters in breast cancer patients in stages one to three who have finished their treatment, such as surgery, chemotherapy and radiotherapy.
Methodology: This trail will be carried out with women with histological confirmed breast cancer who have already completed the primary treatment for breast cancer (including surgery, radiation therapy and chemotherapy) from 6 months to 5 years but keep on hormone therapy. After baseline assessments, the eligible participants will be randomized to the combined exercise group or control non-exercising group. The combined exercise group will follow an eight week exercising program, which consists of three weekly exercise sessions. Each session will last around 60 minutes and will include strength training (with machines and elastic bands) and aerobic exercises on treadmills. Workouts will be guided and supervised by previously trained physical education professionals and physiotherapists. The strength training will comprise nine exercises, which will alternate body segments with maximum repetitions in the first set and the inferior limit of repetitions in the second set. Along the training, the number of series will increase whereas the number of repetitions will decrease. The intensity of the aerobic exercises will be based on the percentage of cardiac frequency of anaerobic threshold. All exercise sessions will take place at the Physical Education School at the Pelotas Federal University, located in Pelotas, Rio Grande do Sul, Brazil.

What is being measured
The primary outcome is the main question the study is designed to answer.
Cardiorespiratory Fitness evaluation change after 8 weeks
We created a protocol on the treadmill to determine the peak oxygen uptake change(VO2peak), the first ventilatory threshold and the second ventilatory threshold. The protocol consists in 1-minute stages. The initial speed is 1.86 miles per hour. In each stage, the speed increases 0.3 miles per hour and every 2 stages, the treadmill inclination increases 1%. The test is interrupted when the subject indicates exhaustion. The respiratory gases will be collected through a portable gas analyzer (VO2000, MedGraphics, Ann Arbor, USA).
The maximum value of VO2 , closed to exhaustion will be considered the VO2peak. The fist and the second ventilatory threshold will be determined by the ventilation versus intensity curve and confirmed by the O2 and Carbon dioxide ventilatory equivalents by two independent physiologists in a visual inspection.

Where is the study taking place?
The record lists 1 site in Brazil. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Cardiorespiratory Fitness evaluation change after 8 weeks (time frame: Testing of VO2peak change - Baseline and 8 week). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Jan 2019.
