swimming freestyle with one arm

It sounds like you are looking for the most efficient one-arm freestyle technique? Is this permanent, or temporary? When we do drills, one-arm free means placing your non-swimming arm at your side, breathe to your non-swimming arm side, and pull as you normally would with your swimming arm. I wouldn't say this is efficient. If I had to be efficient, for example, say I injurned my arm in open water and needed to swim to shore quickly, I guess I would try and place my injured arm out in front of me, leaving it there, and pull with my good arm. If I couldn't place my injured arm out in fron of me, I would do back stroke with my good arm and keep my injured arm by my side, doing whatever sculling I could with my hand. I would alternate this will freestyle as well, but breathing to my pulling arm side (unlike my drill mentioned above). I am sorry to use the term "injured." I don't want you to think I am implying that you are injured.
