Athletic Trainers - As enacted, expands the scope of practice for athletic trainers by authorizing them to treat conditions that limit or prevent a person's participation in certain physical activities rather than just treating injuries that limit or prevent such participation; makes related changes. - Amends TCA Title 63, Chapter 24.

SB 502 expands the scope of practice for licensed athletic trainers in Tennessee. It changes the definition of "athletic injury" to include any condition limiting physical activity participation (not just injuries), allowing trainers to treat such conditions under physician supervision. The bill also explicitly clarifies that athletic trainers are healthcare providers and lists specific procedures they may perform, such as blood glucose monitoring, injections, and wound closure. This directly affects licensed athletic trainers by broadening their treatment authority while maintaining requirements for physician oversight and board certification.
