A couple months ago I blogged about some new performance enhancing uniforms being used by athletes at the Torino Winter Olympics. Well I'm back with a new installment. Earlier this week a team of South Korean researchers unveiled what they call a BioShirt at the National Sports Fesival. Unlike the Adidas uniforms I blogged about previously, the BioShirt is specifically designed with athletics in mind. The shirt monitors a runner's temperature, heart rate and speed and then sends that data to a wrist-monitor via Bluetooth.
