Why the study?
The study investigated the effects of a single bout of high-intensity interval training versus moderate-intensity continuous training on blood glucose homeostasis and exosome levels in young healthy adults.
Does a single bout of high-intensity interval training improve blood glucose homeostasis and exosome levels compared to moderate-intensity continuous training in healthy young adults?
Does a single bout of high-intensity interval training improve blood glucose homeostasis and exosome levels compared to moderate-intensity continuous training in healthy young adults?
A single bout of high-intensity interval training improves glucose homeostasis and increases circulating exosome levels more effectively than moderate-intensity continuous training in healthy young adults.
Acute HIIT may improve glucose homeostasis more than MICT in healthy youth; leaves open clinical translation and exosome roles.
Purpose:The study investigated the effects of a single bout of high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) on blood glucose homeostasis and exosome levels in young healthy adults.Methods: A total of 20 healthy young people aged 20 to 30 years were voluntarily recruited from our local community.The subjects were randomly assigned to either HIIT or MICT. Results:The analyses of variance with repeated measures showed that HIIT resulted in a significant treatment (before vs. after HIIT)×time (0, 30, 60, 90, and 120 minutes during oral glucose tolerance tests) interaction (F (1,9) =5.623, p=0.028) on blood glucose concentrations.HIIT resulted in significant decreases in blood glucose levels at 90 minutes (p＜ 0.05) and 120 minutes (p＜ 0.05).MICT did not result in any significant treatment×time interaction on blood glucose concentrations.Neither HIIT nor MICT resulted in any significant treatment×time interaction on blood insulin concentrations.Finally, there was a significant treatment×time interaction (F (1,19) =11.815, p＜ 0.001) in circulating exosome levels.HIIT resulted in a significant increase in exosome levels, whereas MICT did not. Conclusion:In conclusion, the current findings suggest that HIIT would be a better strategy for improving glucose homeostasis than MICT.Yet, the underlying mechanism(s) remain to be unveiled in a future study.
