Influência do exercício físico na cognição: uma atualização sobre mecanismos fisiológicos

Abstract: RESUMO Embora um crescente corpo de literatura corrobore o papel benéfico do exercício sobre a cognição, não há consenso sobre os mecanismos que norteiam as adaptações cerebrais agudas e crônicas ao exercício. A presente revisão narrativa tem como objetivo apresentar e discutir os mecanismos pelos quais o exercício afeta o desempenho cognitivo. Agudamente, especula-se que os efeitos do exercício sobre a resposta cogni-tiva sejam mediados por aumentos no fluxo sanguíneo cerebral e, por conseguinte, no aporte de… Show more

“…In the current study, we used a conventional resistance exercise prescription (3 series of 8 to 12 repetitions) with a moderate intensity (5 to 8 in the OMNI-RES scale), highly used in the literature and recommended by many authors. 36–38 Even so, we did not observe a significant effect of the intervention.…”

“…Although different studies point to the relevance of intensity in cognitive responses to exercise, 36,39–41 indicating that exercise at moderate intensity can improve cognitive function, 42 Quigley, MacKay-Lyon and Eskes 14 concluded that the duration of the session seems to be a more relevant variable. However, in PLHIV, the impact of these variables seems to be different, given that even reaching the time (> 45 min) recommended by Quigley, MacKay-Lyon and Eskes, 14 our data indicated that resistance exercise did not improve cognitive function.…”

“…Uma explicação para estes resultados é que ambos os exercícios físicos proporcionam um aumento do fluxo sanguíneo cerebral, ofertando um melhor aporte de nutrientes assim como, o aumento do número de neurotransmissores melhorando a capacidade cognitiva (RAMOS;CHAGAS, 2015). A longo prazo, o exercício físico é capaz de promover adaptações cerebrais e plasticidade cerebral que melhora o desempenho cognitivo (FILHO et al, 2014). Os idosos praticantes de musculação apresentam maior força muscular dinâmica e isométrica em membros superiores e inferiores quando comparados a sedentários ou praticantes de outro exercício físico (COELHO et al, 2014).…”

“…The practice of health-promoting and therapeutic physical activity, with minimal risks, is also a factor in the development of autonomy, self-esteem, and comprehensiveness of care. Such a measure can aid in sociability when adopted in therapeutic groups [41], helps in psychomotricity [42], improves cognitive performance [43], promotes the control of various cardiovascular risk factors [44], reduces the cancer risk [45], and favors lower risk of falls and fractures [46]. There is also evidence that regular physical activity can attenuate the effects of aging on the cardiovascular system [47,48].…”
