I wonder if the data collected is accurate like hrt rate, distance etc...Will the girls get a combo real-bra/data bra?
These things have been in used in the NRL (http://www.nrl.com.au) in Australia for a long time now. In training and I believe there are versions that can be worn under a jersey during games. They can put a GPS in them among other things and the data can be very handy for coaching and training purposes.
