ABSTRACT
Abstract This study analyzed the responses of 24 sessions of High Intensity Interval Training (HIIT) and Continuous Moderate (CM) on tissue damage, oxidative stress and glycemic profile of rats in liquid medium. Twenty-four Wistar rats participated, divided into three groups sedentary (GSED), the one who performed the HIIT (GHIIT) and the one who performed the CM (GCM). Performed three times a week alternately for 8 weeks, and the GHIIT performed 20 seconds of exercise for 10 rest. The CM was a moderate intensity swim. GHIIT increased creatine kinase compared to GSED (GSED 140.40 + 35.48 U / I; GHIIT 442.60 + 8.35 U / I; p = 0.0008, representing a percentage increase of 215.24); lactate dehydrogenase was increased in GHIIT and GCM compared to GSED (GSED 112.8 + 28.08 U / I; GHIIT 250.9 + 70.67 U / I, a percentage increase of 122.42; GCM 241.8 + 100.70 U / I, with a percentage increase 114.36; p = 0.006), in contrast, GHIIT increased non-oxidized liver sulfhydryls compared to GCM (GHIIT 498.70 + 214.30 nmol / ml; GCM 270.50 + 104.40 nmol / ml, the percentage change was 84.36; p = 0.03). There was greater glycemic maintenance in the GCM (p = 0.0002). It is concluded that the protocols of HIIT and CM, of this study, point to a possible tissue injury, in contrast, HIIT develops the adaptive capacity of the hepatic antioxidant system and the CM promotes greater glycemic support.
RESUMO
Resumo Este estudo analisou as respostas de 24 sessões de High Intensity Interval Training (HIIT) e Contínuo Moderado (CM) sobre a lesão tecidual, estresse oxidativo e perfil glicêmico de ratos em meio líquido. Participaram 24 ratos Wistar, divididos em três grupos sedentário (GSED), o que fez o HIIT (GHIIT) e o que executou o CM (GCM). Realizados três vezes semanais alternadamente por 8 semanas, sendo que o GHIIT executou 20 segundos de exercício por 10 de descanso. O CM foi um nado de intensidade moderada. O GHIIT aumentou a creatina quinase em relação ao GSED (GSED 140.40 ± 35.48 U/I; GHIIT 442.60 ± 8.35 U/I; p=0.0008, representando um aumento percentual de 215.24); a lactato desidrogenase foi aumentada no GHIIT e GCM em relação ao GSED (GSED 112.8 ± 28.08 U/I; GHIIT 250.9 ± 70.67 U/I, um aumento percentual de 122.42; GCM 241.8 ± 100.70 U/I, com aumento percentual de 114.36; p=0.006), em contrapartida, o GHIIT aumentou as sulfidrilas hepáticas não oxidadas em relação ao GCM (GHIIT 498.70 ± 214.30 nmol/ml; GCM 270.50 ± 104.40 nmol/ml, a variação percentual foi de 84.36; p=0.03). Houve maior manutenção glicêmica no GCM (p=0.0002). Conclui-se que os protocolos de HIIT e CM, deste estudo, apontam para a uma possível lesão tecidual, em contrapartida, o HIIT desenvolve a capacidade de adaptação do sistema antioxidante hepático e o CM promove uma sustentação glicêmica maior.
