Christian and Practicing Martial Arts?

I am an Animal Control Officer and work alone 99 percent of the time. Can a Christian practice and use martial arts or must we turn the other cheek?

Thanks,

John Runer
Update: I have faced and angry dog owner with a psitol and a record! having to kill a man over a dog issue is a deep concern. I have a family that wants me to come home though.
