HIIT protocol used a more realistic intensity rather than for example something like Wingates. 1 minute on then 1 minute active recovery repeated for 10 rounds at 90% of max heart rate.
The MISS/LISS group did 50 minutes steady state at 70% max heart rate.

High-intensity interval exercise induces 24-h energy expenditure similar to traditional endurance exercise despite reduced time commitment
Skelly, LE; Andrews, PC; Gillen, JB; Martin, BJ; Percival, ME; Gibala, MJ
Subjects performed high-intensity interval training (HIIT) and continuous moderate-intensity training (END) to evaluate 24-h oxygen consumption. Oxygen consumption during HIIT was lower versus END; however, total oxygen consumption over 24 h was similar. These data demonstrate that HIIT and END induce similar 24-h energy expenditure, which may explain the comparable changes in body composition reported despite lower total training volume and time commitment.
