Pooling 22 randomised trials with 619 adults, high-intensity interval training reduced pulse wave velocity, a marker of arterial stiffness, by 0.10 m/s more than moderate-intensity continuous training.

What it shows: Solid pooled evidence: 22 trials covering 619 adults point the same way. The honest sizing is that HIIT's edge over steady cardio was 0.10 m/s of pulse wave velocity, a small margin, and the review does not say how long the benefit lasts or who gains most.Meta-analysis · Arch Gerontol Geriatr
