O estudo objetivou comparar diferentes estratégias de supervisão durante 12 semanas de um programa de exercícios domiciliares sobre a função cognitiva de idosos saudáveis. Foi realizado um ensaio clínico, no qual participaram idosos comunitários de ambos os sexos, que foram divididos em dois grupos com diferentes estratégias de supervisão: supervisionado virtualmente por videoconferências durante todas as sessões de treino, ou supervisionado por mensagens de texto. A intervenção para ambos os grupos consistiu em um programa ofertado por meio de vídeos-aula, com frequência de três sessões semanais e duração de 12 semanas. Os desfechos foram avaliados remotamente por videoconferência. Para avaliar a cognição global foi utilizado o Montreal Cognitive Assessment (MoCA) e para o controle inibitório o Stroop test. Foi feita uma análise inferencial, com intenção de tratar, de modelos mistos por simetria composta, considerando intervalos de confiança (IC) a 95% e um nível de significância de 5%. Trinta e oito participantes foram randomizados e alocados em um dos grupos (81,6% mulheres, média de idade de 68,39 ± 6,48 anos, massa corporal média de 69,82 ± 12,15 kg, altura média de 1,59 ± 0,06 m, índice de massa corporal médio de 27,82 ± 4,88 kg/m²; e 94,7% com mais de 12 anos de estudo). Não houve diferenças estatisticamente entre os grupos (p>0,05) e não foram observados efeitos ao longo do tempo nas comparações intra-grupos (p>0,05). Concluiu-se que a supervisão utilizada neste estudo não promove ganhos cognitivos adicionais ao programa de exercícios domiciliares supervisionado por mensagens de texto em idosos saudáveis.
