AUSTIN, Texas — New rules starting Thursday mean high school students looking to play in the marching band have to get physicals.

If you think about marching band, especially in Texas heat, students can be playing in 100-degree weather and carrying quite a bit of weight. A doctor we spoke to with Baylor Scott & White said getting physicals could help prevent dangerous situations and keep students safe.

The University Interscholastic League (UIL) said starting Aug. 1, high school band students need to have a physical their freshman and their junior year just like those who play sports, such as football and basketball. This change also applies to junior high, but students can do it in seventh or eighth grade.

With the new rule, band members will have to have a medical history form with them each year, proving they've had the exam before they practice. Dr. Steve Ramirez said this probably because band can be physically demanding. School leaders may be worried about cardiac issues and want to catch things early.

“I think the purpose is to make sure you're picking up on signs and symptoms of things that could either preclude you from participating or things that could also be dangerous,” said Ramirez. “You worry about things like an enlarged heart or cardiomyopathy, things like that. You also worry about heart murmurs that have gone undiagnosed."

Back in April, Austin ISD provided free physicals and included band students for the first time, realizing this change was coming. AISD said about 1,000 students in all sports took advantage.

Dr. Ramirez added this is all about prevention and making sure students are safe. This way they can spot things early, instead of finding out later that something was wrong.

UIL has more details on the marching band rule change.
