About a week ago I started to extend the glide out of my turn. I notice
that w/o additional effort, I would go from 17 to 15 strokes per 25yds.
The only problem was that I would start running out of air during the
glide, and I don't like the feeling. I had tried this before and
haven't een able to get my lungs to adapt to the extra effort (I cannot
stand hypoxy drills). Instead, I decided to explode out of the wall,
even though I would continue to swim slowly and relaxed. Well, it
worked great. I would come out of the water far from the wall and fast
enough not to run out of air. The leg explosion did not seem to get me
any more tired and my time in 2000 yds came down by a couple of minutes
without much effort. A couple of days after my leg explosive flipturns,
and my lower back is killing me. I did another swim where I would do
explosive turns. I noticed that I use my lower back musles a lot. I
arched considerably and extend explosively.
I am going to continue doing this. I think in a few more days my
muscles will adapt to the new effort and will not hurt anymore, and
I'll have a stronger lower back. However, it is interesting to me that
after doing flips for a gazillion years, adding this explosive trick
can get me so sore. I guess that age is catching up with me.
