Abstract(s)
O exercício físico (EF) é um tratamento eficaz para a depressão, sozinho ou como
coadjuvante. Contudo, dada a falta de indicadores relativos à frequência, intensidade,
duração e tipo de EF, o presente estudo visa sintetizar e analisar o efeito dose-efeito
dos diferentes protocolos de EF em sujeitos adultos no tratamento da depressão, com
base na análise dos RCTs. A pesquisa foi realizada utilizando bases de dados
electrónicas Web of Science, PubMed e Cochrane Library. Foram identificados estudos
com uma intervenção baseada em exercícios, publicados até 31 de Dezembro de 2021.
Foram também incluídos ensaios controlados aleatórios e meta-análises envolvendo
adultos com depressão. Foram seleccionados dez estudos, incluindo um total de 956
sujeitos. Os tamanhos dos efeitos foram resumidos utilizando diferenças médias
padronizadas (95% de intervalos de confissão) através de modelos aleatórios
efetuados. Os resultados obtidos no presente estudo reforçam que o exercício parece
ser benéfico na melhoria da depressão entre adultos com 18-65 anos de idade.
Observou-se que intervenções com duração superior a 150 min/semana de intensidade
moderada e intervenções de grupo parecem ter um efeito mais significativo na redução
da depressão. Estudos revelaram que o EF aeróbico, comparado com o treino de
resistência ou flexibilidade, tem um efeito mais positivo sobre a depressão. Concluímos
que o EF pode ser uma forma de reduzir a depressão e pode ser utilizado como uma
possível ferramenta adjuvante para tratamentos farmacológicos e/ou alternativos.
Physical exercise is an effective treatment for depression, alone or as an adjunct. However, given the lack of indicators regarding the frequency, intensity, duration and type of PE, the present study aims to synthesize and analyze the dose-effect of differ ent PE protocols in adult subjects in the treatment of depression, based on the analysis of RCTs. The search was conducted using Web of Science, PubMed and Cochrane Li brary electronic databases. Studies with an exercise-based intervention published by December 31, 2021, were identified. Randomized controlled trials and meta-analyses involving adults with depression were also included. Ten studies were selected, includ ing a total of 956 subjects. Effect sizes were summarized using standardized mean dif ferences (95% confession intervals) by effected randomized models. The results ob tained in the present study reinforce that exercise appears to be beneficial in improv-ing depression among adults aged 18-65 years. It was observed that interventions last-ing above 150 min/week of moderate intensity and group interventions seem to have a more significant effect on reducing depression. Studies have revealed that aerobic PE, compared to resistance or flexibility training, has a more positive effect on depression. We conclude that PE can be a way to reduce depression and can be used as a possible adjunctive tool for pharmacological and/or alternative treatments.
