strong words in the first sentence.
"Performance during stretch-shortening cycle exercise is influenced by the visco-elastic properties of the muscle-tendon units. During stretching of an activated muscle, mechanical energy is absorbed in the tendon structures (tendon and aponeurosis) and this energy can subsequently be re-utilized if shortening of the muscle immediately follows the stretching. According to Biscotti (2000), 72% of the elastic energy restitution action comes from tendons, 28% - from contractile elements of muscles.

This isn't HIIT but this paper is very paradoxical I guess, more slow-twich muscle fibers after repeat 5s sprint programme. Trin to get the full-text
