There is some confusion around the change to Law 4 - The Player's Equipment. The law reads:
The first paragraph is the source of the confusion around this rule update. People read “Electronic performance and tracking systems” and think “Oh, that’s what my fitbit does!” However, that is not the case. Just check out these descriptions of a EPTS from the FIFA website: and . Note that from reading these descriptions, it is pretty clear that a fitbit device, capable of working as a device that can measure heartrate and other physiological parameters, can be part of the system, but it is not an EPTS by itself. Fitbits are Wearable Technology only. The AYSO Regions in the Cedar Rapids area do not have an EPTS. Thus, fitbits and like devices are not allowed any more than we allow watches or friendship bracelets.
