Moderate-Intensity Continuous Training (MICT) increases resting brachial artery diameter and enhances low flow-mediated constriction (L-FMC) in obese adults, despite not improving flow-mediated dilation (FMD).
If you prefer moderate continuous exercise (like steady-state cycling), you can still improve your blood vessel structure (diameter) and constriction function (L-FMC) even if your dilation (FMD) doesn't improve. This suggests MICT is not 'ineffective' for vascular health, just different in its benefits compared to HIIT.
MICT had a significant increase in preocclusion baseline diameter ... MICT showing a significant decrease in L-FMC ... HIIT and MICT produced different vascular adaptations ... with MICT increasing resting artery diameter and enhancing L-FMC.
Why this rating
Statistically significant findings for MICT group on diameter and L-FMC.
