I just started thinking about something that will probably sound pretty stupid to a few of you, but try not to flame me too much if I’m way off base with this.
I noticed that Chad Waterbury thinks that swimming is a good way to build endurance for MMA fighters. I’ve also met a few SEALs who were pretty big guys even though their job probably requires more endurance than overall strength.
I’ve lately stepped up my endurance training using Waterbury’s Hammer Down Endurance program, but have noticed a slight decrease in squatting strength since adding in the 2 mile runs after the circuit. Although I’m doing descent with the circuit (around 23 minutes), my two mile run is just over 15 minutes right now so I’m sure this slow pace has something to do with it.
Anyway, all of this got me thinking about how swimming would affect muscle fiber types compared to running. We all know that developing aerobic endurance through long runs eventually leads to a decrease in strength and speed. Would swimming somehow help develop a high rate of aerobic endurance while preventing a switch of muscle fiber types? I’m sure there would be some strength loss with very long swims but would it be better than running?
I am a very inexperienced swimmer so I don’t even know which muscles get the most work while swimming. But I’m thinking it would take away a lot of the leg work that is involved in running, therefore preventing a loss in explosiveness derived from the hips and thighs.
Again, this all may sound really ignorant to some of you guys with a lot of knowledge, but I was just wondering your opinion.
Thanks a lot and sorry about the long winded post.
