I was surfing channels at the gym the other day and found Sport Science, a show which breaks down the dynamics of many different sports in really cool ways. The scientists on the show use high-tech sensors and HD cameras, as well as digitally-created simulations to analyze and measure the physics and anatomical aspects of sports. I've seen another episode where they measured the explosive power of fast-twitch muscle fibers in a football running back.
This video is about Drew Brees, and how he can throw a football accurately. The part I found most interesting begins at 5:50, where they use the sensor on the football to analyze its flight.
