Fig. 5.

In elderly subjects the fascia lata is not always in direct contact with muscle but partly separated by layers of adipose tissue (pink), which are part of intermuscular adipose tissue (IMAT). A tight muscle envelope excluding most or all of the pink ROI would significantly decrease the volume of IMAT (yellow). In younger subjects Fig. 2a there is no or very little adipose tissue located between muscle and fascia.
