Abstract(s)
Introdução: A relevância da atividade física com terapia coadjuvante do cancro tem vindo a
ser comprovada em vários estudos. Além da distância e dos custos, a pandemia do COVID-19
criou mais uma barreira ao exercício, tornando mais difícil o acesso a programas de exercício
físico supervisionados em contexto presencial. As intervenções em contexto à distância, via
internet, garantem a supervisão de programas individualizados e cientificamente validados,
podendo ser uma maneira segura e eficaz de proporcionar o acesso a estes programas, a
pacientes com cancro de mama, mantendo-os motivados. Este é um desafio das equipas
multidisciplinares que acompanham estas pessoas.
Objetivo: Este estudo teve como objetivo analisar a viabilidade, aceitação e eficácia de uma
intervenção de exercício supervisionado de 8 semanas, em modo presencial (que é
considerado o estado da arte) e modo supervisionado remotamente, em pacientes
sobreviventes de cancro da mama, após tratamento primário, com intenção curativa. Os
outcomes secundários incluíram medidas antropométricas (perímetro da anca, cintura, crural
médio e bicipital) e aptidão funcional (força dos membros inferiores, força dos membros
superiores, equilíbrio estático e flexibilidade)
Método / Desenho: Este foi um estudo piloto randomizado controlado de 8 semanas com um
total de 12 pacientes do sexo feminino, 33-65 anos, com diagnóstico de cancro de mama entre
os estágios Ia-IIIa. Antes das avaliações iniciais, as participantes foram randomizadas para
grupo presencial supervisionado e grupo homebased supervisionado remotamente com uma
prescrição de exercício igual: 2 dias por semana de treino combinado (aeróbio, resistência e
flexibilidade) e 1 dia de treino aeróbio, com pelo menos um dia de descanso entre cada
sessão.
Resultados: Não existiram abandonos durante a intervenção, logo a taxa de retenção foi de
100% nos programas supervisionados presencial e homebased. A adesão à duração do treino
aeróbio teve um valor médio de 83%, em todos os participantes. Entre os grupos variou em
entre 80% a 86%, homebased e presencial, respetivamente. A taxa de adesão ao volume
prescrito (séries x repetições) de treino de força, teve um valor de 74% ± 28,2%, em toda a
amostra. O grupo homebased apresentou valor um médio de 72,7% ± 39,2% e o grupo
presencial um valor médio de 75,4% ± 14,6%. A taxa de adesão à frequência foi de 82,6% no
grupo homebased e 80,6% no grupo presencial. Após a intervenção de 8 semanas, os grupos
homebased e presencial melhoraram significativamente a força de preensão manual do lado
não operado (grupo homebased 3,33 ± 2,06 p <0,05; grupo presencial 3,33 ± 1,50). Melhoria

significativa também foi observada favorecendo o grupo presencial no teste “sit to stand 30´´
com aumento do número de repetições (3 ± 2, p <0,05) e diminuição do perímetro da anca (-
3,08 ± 2,44, p < 0,05).
Conclusão: Os resultados indicam que o protocolo On4Rehab foi viável e seguro para seus
participantes. Também mostrou potencial para melhorar a aptidão funcional (força de
membros superiores e inferiores) e medidas antropométricas (perímetro da anca). Os
resultados são encorajadores para continuar a aplicar este tipo de programa de exercício
combinado supervisionado de 8 semanas em amostras maiores, em estudos controlados
randomizados e avaliar a sua viabilidade e efeito nos resultados de aptidão funcional.
Background: The relevance of physical activity as a co-adjuvant cancer therapy has been proven in numerous studies. In addition to distance and costs, the COVID-19 pandemic created yet another barrier to exercise, making access to supervised center-based (CB) exercise programs more difficult. Web-based interventions, ensure supervision of scientifically validated tailored programs, and can be a safe and effective way to deliver exercise to breast cancer (BC) patients, keeping them motivated. This is the challenge for the multidisciplinary teams who accompany these people. Purpose: This study aimed to analyze the feasibility, acceptability, and effectiveness of an 8- week supervised exercise intervention, in face-to-face mode (which is considered state of art) and remotely supervised mode, in BC survivor’s patients, after primary treatment with curative intent. Secondary outcomes included anthropometric measures (hip, waist, middle crural and bicipital circumferences) and functional fitness (lower limb strength, upper limb strength, static balance, and flexibility) Methods/Design: This was an 8-week pilot randomized controlled study with a total of 12 female patients, 33-65 years, diagnosed with breast cancer between stages Ia-IIIa. Before baseline assessments, participants were randomized to supervised CB and remotely supervised home-based (HB) groups with a similar exercise prescription: 2 days per week of combined training (aerobic, resistance, and flexibility) and 1 day of aerobic training, with ate least one day of rest between each session. Results: With no dropouts during the intervention, the retention rate was 100% in CB and HB supervised programs. The adherence to duration of aerobic training had an average value of 83%, in all participants. Between groups it varied in a range from 80% to 86%, HB and CB, respectively. The adherence rate to the prescribed volume (sets x repetitions) of strength training, had a value of 74% ± 28.2%, in all sample. The HB group had an average value of 72.7% ± 39.2% and the CB group an average value of 75.4% ± 14.6%. The adherence rate to frequency, was 82.6% in HB group and 80.6% in CB group. After the 8-week intervention, the HB and CB groups had significantly improved handgrip strength on the non-operated side (HB group 3.33 ± 2.06 p < 0.05; CB group 3.33 ± 1.50). Significant improvement was also observed favoring the CB group on the sit to stand 30´´test with increase of the number of repetitions (3 ± 2, p < 0.05) and decrease on the hip circumference (-3.08 ± 2.44, p < 0.05). Conclusion: Results indicate that the On4Rehab protocol was feasible and safe for its participants. It has also showed potential to improve functional fitness (upper and lower limb strength) and anthropometric measures (hip circumference). The results are encouraging to continue to apply this type of 8 week supervised, combined exercise program in larger samples, in randomized controlled trials (RCT), and assess their feasibility and effect on functional fitness outcomes.
