A statement from the district, located in west Oklahoma City, says the 11th grade student was participating in offseason conditioning when he collapsed Friday afternoon. The student was taken by ambulance to an Oklahoma City hospital where he died about 9:45 a.m. Saturday.
District spokesman Steve Lindley confirmed the student's identity Monday as 16-year-old Traquan Patton.
The statement says students participating in the conditioning class had the choice of running, jogging or walking a course after the end of the regular school day Friday.
Officials say the students were supervised by four teachers who are also coaches, and water stations were positioned at the beginning and about halfway through the course.
