Serum HMW adiponectin levels do not significantly increase after 16 weeks of HIIT, but changes in adiponectin are strongly associated with changes in visceral adipose tissue (VAT) loss.

Don't expect HIIT to magically boost your adiponectin levels. However, if you lose visceral fat through HIIT, your adiponectin levels will likely improve as a result of that fat loss, not the exercise itself.

There was no change in serum HMW adiponectin concentration after the 16-week intervention in either group or the combined group... percent changes in serum adiponectin were associated with percent changes in AT, especially VAT in the combined group (ρ = -0.72, p < 0.01).
