Aerobic exercise, interleukin 6, irisin, obesity, metabolismResumo
A obesidade é uma condição caracterizada pelo acúmulo excessivo de gordura corporal além dos limites normais. A irisina e a IL-6 são miocinas que têm a função de converter tecido adiposo branco em tecido adiposo marrom, resultando em termogênese que induz gasto energético e tem implicações na redução do acúmulo excessivo de gordura. Este estudo tem como objetivo demonstrar a resposta do exercício ergonômico em esteira e bicicleta de intensidade moderada na perda de gordura e aumento da secreção de miocinas em mulheres adolescentes obesas. Um total de 30 mulheres obesas preencheram os critérios com índice de massa corporal (IMC) de 30,02 ± 2,97 kg/m2 e idade de 21,27 ± 1,31 anos. Eles foram recrutados para o estudo e realizaram uma única sessão de exercícios aeróbicos em bicicleta ergométrica (AEEG) e exercícios aeróbicos em esteira. (ATEG) por 45 min. Medição de miocinas, ou seja, irisina e IL-6, por ensaio imunoenzimático (ELISA) em todas as amostras. A análise estatística foi realizada por meio do teste ANOVA unidirecional e do teste post hoc HSD de Tukey com significância ao nível de 5%. Os resultados mostraram que os níveis médios de irisina pós-exercício foram 72,82±42,96 ng/mL no CTLG, 282,50±75,96 ng/mL no AEEG, 488,14±61,30 ng/mL no ATEG e p = 0,000. Os níveis médios de IL-6 pós-exercício foram 51,09±15,68 pg/mL no CTLG, 58,94±3,62 pg/mL no AEEG, 129,29±52,65 pg/mL no ATEG e p = 0,000. Os ∆ FATs médios foram -0,02 ± 0,34% no CTLG, -0,35 ± 0,19% no AEEG, -0,46 ± 0,18 pg/mL no ATEG e p = 0,002. Ambas as intervenções de exercício aumentaram consistentemente os níveis de irisina, enquanto os níveis de IL-6 aumentaram apenas com exercícios aeróbicos em esteira. Da mesma forma, a gordura corporal só diminuiu após uma sessão de exercícios aeróbicos em esteira em comparação com exercícios aeróbicos em uma bicicleta ergonômica.
