What are the benefits of physical activity in patients with breast cancer on physical and psychological health? A systematic review of randomized clinical trials/QUAIS OS BENEFICIOS DA ATIVIDADE FISICA EM PACIENTES COM CANCER DE MAMA SOBRE A SAUDE FISICA E PSICOLOGICA? UMA REVISAO SISTEMATICA DE ENSAIOS CLINICOS RANDOMIZADOS

Introduction: Breast cancer (BC) is a worldwide public health problem that affects women's body image and sexuality. Physical exercise has been considered one of the significant and effective non-pharmacological strategies to minimize physical and psychological consequences. Objective: To identify and describe the scientific evidence on the interventions of physical exercises in the physical and psychological health of individuals with BC. Material and Methods: A systematic review was performed blindly and independently, from December 2022 to January 2023, according to PRISMA guidelines. The results were obtained by direct online access through the databases: PubMed, Science Direct and Capes, using the combination of the following descriptors in English: Breast Neoplasms, Physical activity, and Physical exercise. Results and Discussion: A total of 17 studies were selected, with a sample of 2,091 participants with an average age of 53 years. The studies included aerobic, resistance, stretching, and strengthening exercises. Although combined exercises result in better overall quality of life, anxiety, depression and muscle strength indices, resistance exercises alone also promote good results for this population. Conclusion: Patients with BC can benefit from the practice of physical exercises, improving aspects related to general physical and psychological health. This study can still contribute with new works considering the minimally described information about which types of interventions can be applied for an effective result. It is recommended that more randomized clinical trials be performed to obtain more concise results. Keywords: Breast Neoplasms. Physical activity. Physical exercise.
