U.S. Soccer Federation Recognize to Recover heat guidelines for soccer training and match play (youth and amateur): an on-site WBGT reading and a regional category set one of five alert levels (green/yellow/orange/red/black) with rest-break, training-duration, conditioning and cancellation recommendations. Only the Region Category 1 (most protective) column is encoded. A sports overlay, not an occupational work/rest rule.
