Wednesday was the final night of practice before 21 students from the Jenks Martial Arts Academy head to Louisiana to compete for a national championship.
This weekend, the students will compete with 500 others in sparring, grappling and demo teams at the UTA grand nationals in Shreveport.
There will also be a special competition for the most powerful kicks and hand strikes.
"It’s exciting to see these guys put themselves on the line with the risk of losing. It takes a lot of courage to do that," said Chief Instructor Justin Dunham.
Three instructors from Jenks will also be testing for high ranks. Two will be trying for 4th-degree and one for 5th-degree black belts.
