SAN ANTONIO – This fall, the University Interscholastic League (UIL) is introducing new safety measures for Texas schools, focusing on monitoring wet-bulb globe temperature (WBGT) during practices. These guidelines aim to keep student-athletes safe from heat-related illnesses, which can be particularly dangerous during the hot Texas months.
So, what exactly is WBGT? It’s a measurement that takes into account heat, humidity, wind, and sunlight, giving a more comprehensive understanding of heat stress compared to just air temperature. This is crucial for athletes who train in the heat.
In our area, schools must follow Class 3 guidelines set by the American College of Sports Medicine to ensure athletes’ well-being. To measure WBGT accurately, athletic trainers will need to use a scientifically approved device. This device should be set up at least 30 minutes before practice starts and checked every 30 minutes throughout the session. Schools can also utilize an approved internet-based WBGT forecast.
“Our training staff does a great job of letting us know this is where we think (the WBGT) is going to be,” said Brian Null, head coach for La Vernia High School’s football team. He emphasized the importance of having water readily available and the establishment of cooling stations to help athletes manage heat stress.
When the WBGT reaches 82 degrees, schools are expected to have a rapid cooling zone prepared for student use. This proactive step is vital to prevent heat-related issues before they escalate.
Interestingly, while training staff are not required to document their WBGT readings, UIL recommends that they do keep records for safety and accountability. It’s important to note that these WBGT protocols do not apply to games and contests, as UIL states that most heat-related incidents occur during practices when the number of participants is significantly higher.
UIL also warns that failure to adhere to WBGT guidelines may result in penalties, underscoring the seriousness of these new safety measures.
Overall, UIL believes that coaches and athletic directors have demonstrated the commitment to implement safe practices. These new guidelines are another step towards prioritizing the health and well-being of student-athletes in Texas.
