DARPA today has a long-term, $3 billion program to help make such a “Metabolically Dominant Soldier.” In other words, the military is studying how to use technology and biology to meld man and machine and transcend the limits of the human body. Described the project director, “My measure of success is that the International Olympic Committee bans everything we do" The $3 billion program is definitely trying to achieve transhuman performance goals.

The wearable gear would enable running at 100 meter olympic sprinter speed for hours and the 7 foot vertical leap, the wall crawling, personal flight, invisibility, greatly enhanced strength, better body armor and carrying bigger and more powerful weapons.

UPDATE: Advanced gene therapy could provide cheetah or gorilla quality muscles in people for 45 mile per hour speed or five to ten times strength
