Brief Summary

Background: Breast cancer is the type of cancer that mostly affects women in the world. Although physical and psychological side effects accompany cancer and the aggressiveness of the treatment, regular practice of physical exercise is considered a non-pharmacological tool to improve the quality of life of breast cancer survivors. The present study aims to evaluate the effects of aerobic training programs in aquatic and land environments plus a health education program, compared with a health education program alone, on cancer-related fatigue and other health-related outcomes in breast cancer survivors.

Methods: The WaterMama trial is a randomized, single-blinded, three-arm, parallel, superiority trial. Forty-eight women, ≥18 years of age, who have completed primary treatment and been diagnosed with stage I-III breast cancer are recruited. Participants are randomly allocated on a 1:1:1 ratio to 12-week interventions of aerobic exercise training programs either on the aquatic or land environment two times per week plus health education, or an active-control group receiving health education intervention, once a week. Cancer-related fatigue (primary outcome), physical fitness (i.e., muscle strength of the knee extensors, muscle thickness and muscle quality of quadriceps, resting heart rate, maximum oxygen consumption, and performance in functional tests), mental health (i.e., depressive and anxiety symptoms), cognitive function, pain and quality of life are measured before and after 12 weeks of intervention. The analysis plan will use an intention-to-treat approach and protocol criteria.

Discussion: The conceptual hypothesis is that both training programs plus health education positively affect cancer-related fatigue, physical fitness, mental health, cognitive function, pain, and quality of life compared to the health education group alone. Additionally, it is expected that the aquatic program plus health education to provide more significant effects on cancer-related fatigue and physical parameters due to its multi-component character, with a consequent greater positive impact on other investigated parameters in this group.

Study Groups

Aquatic training plus health education group

Aerobic exercise training program in the aquatic environment twice a week plus health education program once a week

Group Type: EXPERIMENTAL

Aquatic Training Plus Health Education

Intervention Type: OTHER

Participants perform a 12-week training program with two weekly exercise sessions on non-consecutive days. Sessions last 45 min (5 min of warm-up, 35 min of exercise, and 5 min of stretching) throughout the intervention period. The intervention is performed at the thermal pool sector of Clube Brilhante in Pelotas city. The pool water temperature is maintained between 30-32°C, with participants immersed in the depth level between the xiphoid process and shoulders. The aquatic training group performs the following water aerobics exercises: stationary running, frontal kick, cross-country skiing, and butt kick during the stimulus and jumping jacks during the active recovery. The training session is collective, with 3 to 6 participants, supervised by two experienced instructors, one outside and one inside the pool. The group also receives the booklet and the offer of weekly meetings of an educational program (30 min before one of the training sessions) with the same interactive lectures.

Land training plus health education group

Aerobic exercise training program in the land environment twice a week plus health education program once a week

Group Type: EXPERIMENTAL

Land Training Plus Health Education

Intervention Type: OTHER

Participants perform a 12-week training program with two weekly exercise sessions on non-consecutive days. Sessions last 45 min (5 min of warm-up, 35 min of exercise, and 5 min of stretching) throughout the intervention period. The intervention occurs at the School of Physical Education, Federal University of Pelotas. Depending on weather conditions, the land training group will perform aerobic training with walking/running exercises in a flat outdoor environment or inside a multi-sport gym. The training session will be collective, with 3 to 6 participants, supervised by two experienced instructors, one at the starting point and the other following the movement of the participants. In addition, the group receives the booklet and the offer of weekly meetings of an educational program (30 min before one of the training sessions) with the same interactive lectures.

Health education group

Health education program once a week

Group Type: ACTIVE_COMPARATOR

Health Education

Intervention Type: OTHER

The intervention occurs at the School of Physical Education, Federal University of Pelotas. The intervention consists of an educational program with weekly lectures of approximately 30 min. The lectures are led by a qualified health professional, using expository and interactive approaches on topics that cover basic knowledge related to breast cancer and complementary therapies. Additionally, each participant receives a self-care booklet containing information about the topics addressed during the meetings. Qualified professionals give lectures on the following topics: 1) fatigue and quality of life; 2) anxiety and depressive symptoms; 3) body image and sexual function; 4) self-esteem; 5) self-care; 6) sleep; 7) cognitive function; 8) symptoms in the arm and breast; 9) pain and arthralgia; 10) body composition and bone health; 11) eating habits; 12) physical activity.
