Summary

Breast cancer (BC) is one of the most common cancers among women worldwide, with survival rates steadily improving due to advances in early detection and treatment. Despite these improvements, survivors frequently experience long-term side effects such as fatigue, reduced physical function, osteosarcopenia (loss of muscle mass and bone density), and diminished quality of life (QOL). These sequelae often lead to loss of independence, increased frailty, and reduced participation in daily activities. Physical activity, particularly structured and supervised programs, has been shown to mitigate many of these effects. Concurrent training, which combines strength, cardiovascular, and neuromotor exercise, provides a comprehensive approach that targets muscle mass, bone health, and functional mobility. However, adherence to regular physical activity in this population remains low, with most survivors not achieving recommended levels of at least 150 minutes per week of moderate-to-vigorous exercise. This pilot randomized controlled trial aims to evaluate the effects of a 6-week supervised concurrent training program in breast cancer survivors. The program includes 12 supervised sessions designed to improve exercise adherence, physical activity levels, and QOL. The intervention is compared with a control group that receives only a health education session. Outcomes include QOL assessed by the FACT-B questionnaire, physical activity levels measured by the GPAQ, sedentary time, functional fitness, anthropometry, and patient satisfaction. The study is expected to provide evidence that a short-term supervised concurrent training program can improve emotional well-being, preserve QOL, and increase adherence to physical activity in breast cancer survivors.

Detailed description

This randomized, multicenter, parallel-controlled pilot trial was conducted in two tertiary hospitals in Spain to evaluate the effects of a short-term supervised concurrent training program on physical activity adherence and quality of life in breast cancer survivors. Participants allocated to the intervention group completed a 6-week supervised concurrent training program consisting of 12 sessions (two sessions per week, approximately 60 minutes per session). The training program combined resistance, cardiovascular, and neuromotor exercises and was designed to address muscle strength, cardiorespiratory fitness, coordination, and functional mobility. Exercise sessions were supervised by qualified exercise professionals trained in oncology rehabilitation. Exercise intensity was individually adjusted and monitored to ensure participant safety and adherence to the prescribed training load. The control group attended a single educational session focused on healthy lifestyle and nutrition and did not participate in the exercise program. Both groups continued to receive usual oncological follow-up throughout the study period. Assessments were conducted at baseline, immediately after the intervention (6 weeks), and during follow-up at 3 and 6 months to evaluate changes over time. Ethical approval was obtained from the institutional ethics committees of the participating centers (protocol code 2018/0009), and written informed consent was obtained from all participants prior to study participation.

Interventions

Type	Name	Description
OTHER	concurrent	The concurrent training program is divided into three types of training: endurance, cardiovascular and neuromotor. Resistance training sessions were performed in a circuit format with \>30" rest periods between exercises. The volume of work ranged from 8 to 12 repetitions at 60% of the estimated 1 maximum repetition (RM). The cardiovascular work time per session ranged from 25-50 min depending on the intensity of the exercise and the intensity was regulated according to the maximum heart rate (FHR) estimated for each subject between 60-75% The neuromotor training intensity of the sessions was low. The participants wore a heart rate monitor and were instructed not to exceed 60% of their HRF
BEHAVIORAL	Health Education Session	Single formative session on healthy lifestyle and nutrition provided to both groups. Control group received only this session without concurrent training.
