ObjectiveTo investigate the effects of high-intensity interval training (HIIT) and sprint interval training (SIT) on fat oxidation during exercise (FatOx) and how they compare with the effects of moderate-intensity continuous training (MICT).DesignSystematic review and meta-analysis.Data sourcesAcademic Search Ultimate, CINAHL, Networked Digital Library of Theses and Dissertations, Open Access Theses and Dissertations, OpenDissertations, PubMed/MEDLINE, Scopus, SPORTDiscus and Web of Science.Eligibility criteria for selecting studiesStudies using a between-group design, involving adult participants who were not trained athletes, and evaluating effects of HIIT or SIT on FatOx (vs no exercise or MICT) were included.ResultsEighteen studies of fair-to-good quality were included; nine comparing HIIT or SIT with no exercise and eleven comparing HIIT or SIT with MICT. A significant pooled effect of these types of interval training on FatOx was found (mean difference in g/min (MD)=0.08; 95% confidence interval (CI) 0.04 to 0.12; p<0.001). Significant effects were found for exercise regimens lasting ≥4 weeks, and they increased with every additional week of training (β=0.01; 95% CI 0.00 to 0.02; p=0.003). HIIT and/or SIT were slightly more effective than MICT (MD=0.03; 95% CI 0.01 to 0.05; p=0.005). The effects on FatOx were larger among individuals with overweight/obesity.ConclusionEngaging in HIIT or SIT can improve FatOx, with larger effects expected for longer training regimens and individuals with overweight/obesity. While some effects seem small, they may be important in holistic approaches to enhance metabolic health and manage obesity.

“…A progressão do DM2 decorre de um processo crônico inflamatório na qual espécie reativa de oxigênio (ERO), superóxido e hidroperóxido, estão em excesso e altera os processos fisiológicos, inibindo os mecanismos anti-inflamatórios e antioxidantes potencializados por citocinas pró-inflamatórias. Nesse sentido, a melhoria do estilo de vida de sedentários provoca a diminuição da morbimortalidade de diabéticos (TEIXEIRA de LEMOS et al, 2012), pois a pratica regular de exercício físico (PREF) não só melhora as condições inflamatórias como também os problemas cardiovasculares (GAITÁN et al, 2019).…”

“…No entanto, em análise da PREF em obesos e pré-diabéticos, foi possível notar que os melhores resultados foi para o treino intenso com intervalos (TIN) do que o treino intenso contínuo (TIC), ou seja, no TIN há a perda de gordura mesmo em estado repouso e melhoria da atividade insulínica (GAITÁN et al, 2019)…”

Early chronotypes (ECs) are often insulin-sensitive, in part, due to physical activity behaviour. It is unclear, however, if chronotypes differ in resting and/or exercise fuel oxidation in relation to insulin action. Using the Morningness-Eveningness Questionnaire (MEQ), adults with metabolic syndrome (ATP III criteria) were classified as EC (MEQ = 63.7 ± 0.9, n = 24 (19F), 54.2 ± 1.2 years) or late chronotype (LC; MEQ = 47.2 ± 1.4, n = 27 (23F), 55.3 ± 1.5 years). Carbohydrate (CHO) and fat oxidation (FOX, indirect calorimetry) were determined at rest, 55% and 85% VO 2 max , along with heart rate and rating of perceived exertion. Physical activity patterns (accelerometers), body composition (DXA) and insulin sensitivity (clamp, 40 mU/m 2 /min, 90 mg/dl) with an indirect calorimetry for non-oxidative glucose disposal (NOGD) were also determined. While demographics were similar, ECs had higher VO 2 max (P = 0.02), NOGD (P < 0.001) and resting FOX (P = 0.02) than LCs. Both groups increased CHO reliance during exercise at 55% and 85% VO 2 max (test effect, P < 0.01) from rest, although ECs used more fat (group effect, P < 0.01). ECs had lower sedentary behaviour and more physical activity during morning/midday (both, P < 0.05). FOX at 55% VO 2 max correlated with VO 2 max (r = 0.425, P = 0.004) whereas FOX at 85% VO 2 max related to NOGD (r = 0.392, P = 0.022). ECs with metabolic syndrome used more fat in relation to insulin-stimulated NOGD.
