Estresse Oxidativo, Exercício Físico, Óleo de Coco Extra Virgem4
Resumo
Introdução: O estresse oxidativo (EO) ocorre devido ao desequilíbrio entre compostos oxidantes e a atuação de mecanismos de defesa antioxidante. Compostos oxidantes fazem-se presentes no organismo de duas maneiras: exógena - através da dieta, ou endógena - produzido pelo próprio organismo. Tendo em vista o esforço exercido pelo organismo devido ao estímulo da atividade física, estudos apontam a elevação dos níveis de EO em atletas, sendo estes variáveis entre tipo e categoria de esporte, e idade dos mesmos. Objetivo: Avaliar o impacto da atividade física no aumento de espécies reativas de oxigênio (ERO) de forma a induzir significativamente o EO, analisando o tipo de esporte de maior influência e a faixa etária de atletas mais suscetíveis a tal acometimento. Material e métodos: A busca foi realizada em bases de dados digitais, sendo considerados artigos originais e de revisão que atendessem ao tema da pesquisa, disponíveis na íntegra e nos idiomas português, inglês e espanhol. Resultados: Com base nos dados levantados, observa-se que o exercício agudo promove um estímulo ao EO, visto que o mesmo eleva a concentração de lactato, succinato desidrogenase e a atividade de citocromo c oxidase no organismo independente da idade, enquanto os níveis de glicogênio muscular reduziram. Exercícios prolongados reduzem os níveis de glutationa, além de notar-se também que com o envelhecimento os níveis de EO sobem ainda mais, reduzindo a capacidade antioxidante e favorecendo lesões musculoesqueléticas oxidativas. Por outro lado, exercícios moderados auxiliam no controle do EO. A suplementação com óleo de coco extra virgem (OCV) por sua vez auxilia na redução de ERO, suavizando os efeitos sofridos por atletas de forma contínua. Conclusão: Desta maneira, conclui-se que o exercício agudo induz à formação de ERO tendo como consequência o EO, condição esta que pode ser suavizada com o uso de OCV.
