Efeitos Do Exercício Físico Em Comportamentos Relacionados Com a Ansiedade Em Ratos

Abstract: rEsUmoIntrodução: Os efeitos do exercício físico são associados à redução da ansiedade e à manutenção desse estado por diversas horas. Contudo, poucos trabalhos têm investigado os efeitos do exercício agudo sobre a ansiedade. Objetivo: Investigar o efeito agudo da intensidade do exercício físico sobre comportamento relacionado com a ansiedade em modelos animais. Métodos: Cinquenta e seis ratos Wistar machos foram distribuídos aleatoriamente em oito grupos: controle, 0%, 5% e 50% de carga correspondente ao peso… Show more

“…Although it did not show a statistically significant difference in relation to anxiety, which was elevated after the induction of AD (represented by increased freezing time), acute physical exercise had a medium effect in the Alzheimer + Swimming group in the Cohen test. 18 In the study by Barbosa and de Lima,19 in which a greater number of animals were included and the same methodology was used, a significant decrease in anxiety was observed. Although they did not present a statistically significant difference, the factors of shorter open-arm time and longer closed-arm time seem to be related to the defensive response; that is, between the avoidance-exploration conflict in relation to the open arm.…”

“…Passiflora species have several applications in popular medicine, but their most useful properties are anxiolytics and sedatives (GOSMANN et al, 2011;LEAL et al, 2016). Experimental animal models are essential as tools for the recognition of anxiolytic compounds and issues involved in the basis of psychic problems (BARBOSA & LIMA, 2016). Rodents have several characteristics similar to human beings such as their anatomy, biochemical and cellular levels, their brain functions such as anxiety, fear, hunger, and memory (MEER & RABER, 2016).…”
