The people in the study were out of shape to start with
The improved measures were insulin sensitivity index, peak oxygen uptake, and "skeletal muscle mitochondrial content"
No change in body mass
In conclusion, if you're out of shape, you can improve a limited number of fitness measures just as much doing 3x8 minutes of higher intensity exercise as much 3×45m less intense exercise over 12 weeks
