To be become a PE teacher, I think you'd need practical experience with physical education. Getting out and actually doing sports. The theory of it, I don't know. But I'm pretty sure he wouldn't make a very good PE taecher without having thrown a ball through a hoop.
I disagree. Teaching something (including PE) is different than being good in that activity. Being able to teach and supervise PE does not require that one be a star in kickball, four-squares, or basketball. A person with a physical disability or lack of strength and coordination could conceivably study golf and coach golf even if they were a lousy golf player (or had never even played)!
From a legal standpoint, having teaching credentials is the first prerequisite. There are BIG differences between states as far as what is required to get certified, or if an online program is accredited and accepted. Best bet is to contact other PE teachers in your state - maybe at a teacher's conference.
