The more I swim, the more muscle mass I keep putting on. I have low body fat, so it's not a fat concern. My only events are swimming and running, I don't weight train, bike, etc., so there isn't something else that is causing me to bulk up. The muscle mass gain is helping my speed in the pool, but is noticeably slowing down my running. Is it possible to make your existing muscles more efficient? Any thoughts?

No, sorry, can't help you there. No matter how much I swim, I never gain any major muscle mass :bitching:
