Jessica Rose, an orthopedic surgery professor at Stanford, could not believe her eyes.
Tai chi master Chen Xiang, sensor balls taped to key body joints, was demonstrating palm, elbow and fist strikes so fast - and with such force - that the sensors kept flying off his body.
And then she glanced at her computer screen, where Chen's movements were mirrored by an animated stick figure. Like a light-footed dancing skeleton, the figure's grace was undeniable. And frightening. The explosive power of the strikes was stunning - 400 pounds of force generated by Chen's body accelerating from 0 mph to 60 mph in 2.8 seconds - faster than any Lamborghini out on the street.
This level of power was a first for her lab. It's also just plain unusual. In its mainstream form, practiced by millions looking to boost their health, tai chi moves typically are performed in slow motion.
