Would you attend an ESL school that incorporates athletics into the daily schedule?

Sports are one of the universal bridges across cultural and language barriers. I believe they bring one another closer through competition and teamwork. I have started giving small groups of students from Japan lessons in ESL intermixed with athletic activities. The students seem to progress much faster in communicating with their American counterparts, and are much more enthusiastic to master the idiosyncracies of the American-English dialogue by working together on the same team. A strong bond is established that makes lessons much more interactive. If you are from Japan, what do you think of such a teaching method?
