We are talking about smart fibers. Apparently the threads are actually fluid-filled silicone tubes. This is all a hydraulic system woven into your clothes.
“These fabrics, when programmed to expand or contract through thermal, electric, fluid or other stimuli, can produce motion, deformation, or force for different functions.”
That means that if you can control them they will make you stronger and faster. They could also be used in virtual environments to provide tactile feedback.
