Some minor changes were made to competition rules at the WTF General Assembly in Tijuana, Mexico, on March 2, 2010.
According to a WTF news release,
The new rules stipulate that coaches shall not leave the 1 meter by 1 meter marked coach’s zone that indicates the position of the coach.
On the duration of the contest, the new rules stipulate that the duration of each round may be adjusted to 1 minute or 1 minute 30 seconds upon the decision of the technical delegate for the pertinent championships.
The revised rules will be posted on WTF.org and TKDrules.com when they become available.
The last major revision of sparring rules happened in early 2009, and included provisions for video replays and tiered scoring.
