[en] Introduction: According to the AECC, cancer is the uncontrolled growth of cells derived from brain components (primary tumors) or tumor cells located in other areas of the body (metastasis). CNS tumours have their own characteristics that make them different from the rest and their prognosis depends on the anatomical location of the tumour, the location where the tumor growth and the resection of the primary tumor. Objectives: The objective is to design a therapeutic exercise program in oncological patients in the habilitation phase between 14 and 21 years of age diagnosed with a brain tumor, in order to decrease or prevent side effects generated during the treatment of radiotherapy or chemotherapy, and to increase aerobic and anaerobic resistance, muscle mass, motor and cognitive function, quality of life and psycho-social level. Methodology: We propose an experimental analytical study of longitudinal cut and of prospective character. The target population of our study is constituted by all those patients who were diagnosed with a brain tumour and who have already undergone surgery and they are undergoing radiotherapy and/or chemotherapy. They participate in the AECC, in the children's unit of the CHUAC (Hospital Complex of A Coruña), of the oncological hospital of Galicia or other type of private associations and patient associations. These patients will be randomized in 2 groups (control and experimental group). The control group will only receive the conventional medical treatment, while the experimental group will also carry out the proposed therapeutic exercise program, based on a combination of endurance aerobic and high intensity interval training, together with MMSS, MMII and/or trunk strengthening training depending on the day of the week. This intervention will have a total duration of 15 weeks, in which the therapeutic exercise program will be executed in the first 12 weeks ( 3 sessions/week, 80 minutes/session).

[gl] Introducción: Denomínase cancro, segundo a AECC, ao crecemento descontrolado de células derivadas de compoñentes cerebrais (tumores primarios) ou de células tumorais localizadas noutras áreas do organismo (metástase). Os tumores do SNC presentan unhas características propias que os fan distinguirse do resto e o seu prognóstico depende da localización anatómica do tumor, do lugar de crecemento e da resección do tumor primario. Obxectivos: O obxectivo principal é deseñar un programa de exercicio terapéutico en pacientes oncolóxicos en fase de habilitación entre os 14 e 21 anos diagnosticados de tumor cerebral, co fin de diminuír ou previr os efectos secundarios xerados durante o tratamento da radioterapia ou quimioterapia, e aumentar a resistencia aeróbica e anaeróbica, masa muscular, a función motora e cognitiva, a calidade de vida e o nivel psico-social destas persoas. Metodoloxía: Proponse un estudo analítico experimental de corte lonxitudinal e de carácter prospectivo. A poboación obxecto do noso estudo constitúena todos os pacientes que foron diagnosticados con tumor cerebral que xa foron operados e están a recibir radioterapia e/ou quimioterapia. Participan na AECC, na unidade infantil do CHUAC (Complexo Hospitalario de A Coruña), do hospital oncolóxico de Galicia ou outro tipo de asociacións privadas e asociacións de pacientes. Estes pacientes aleatorizaranse en 2 grupos (grupo control e experimental). O grupo control só recibirá o tratamento médico convencional, mentres que o experimental tamén levará a cabo o programa de exercicio terapéutico proposto, baseado na combinación dun adestramento aeróbico de resistencia e de intervalos de alta iintensidade, xunto cun adestramento de fortalecemento dos MMSS, MMII e/ou tronco segundo o día da semana. Dita intervención terá unha duración total de 15 semanas, nas cales se executará o programa de exercicio terapéutico nas primeiras 12 semanas ( 3 sesións/semana, 80 minutos/sesión).
