I cut back on computer usage but the debilitating pain in my arm and shoulder persisted. What's the cause? Only after swimming twice in one day did I realize the pain comes from how I turn in the pool. I can't flip turn, so I used my right arm to hoist my legs to the wall for push off. Too much. I've switched now to using both arms and the pain has lessened significantly.
I recently increased the length of time I swim from 70 minutes to 80 minutes. What I noticed about adding time is it isn't added in the middle when I still feel good. No, the added time necessarily comes at the end of the workout when I'd rather quit. But after a couple of weeks of swimming the extra ten minutes, I've gotten used to it.
I'm also attempting to change my breathing pattern. I presently breathe every third stoke which has the added benefit of working the kinks out of my neck. But some mornings the kinks don't work out no matter what, so I breathe every fifth stoke. I can do this for only about 15 minutes / 10 laps. I pull stronger on non-breath strokes. I equate this to 100 m hurdles technique, 3-step vs. 5-step1, except the numbers are inverted. Breathing every fifth stroke is preferred but I need to work up to it.
Beginning Tuesday, the swim team takes over the pool from 5 am to 6 am, the principle time I go each weekday, until February. I joined another pool in the meantime which doesn't open until 6 am. The other pool is geographically closer to my house but the later opening still means less time overall. I'll have to see how it goes. Most days I can swim after I've taken the kids to school.
1 I have never ran hurdles, neither have I ever swam competitively.
