So I tend to drift left in open water and figured it was lack of symmetry in stroke, even though I breath bilaterally every 3rd stroke. On a VASA Ergometer, I found my left side power to be ~2/3 of the right side power.
As the dry land ergometer is much less sensitive to technique that wet swimming, there must be a muscular strength imbalance to deal with L-to-R. While technique imbalance might have caused the strength imbalance, I've drifted left ever since taking up swimming about 3yr back, so I think it was a pre-existing condition rather than caused by technique imbalance.
Any thoughts on a fix?
Sight often.
I hurt my left shoulder last year and have less strength in the left arm, I also lose power sooner on the left. If I don't sight regularly, I swim in circles.
I'm focusing on strengthening my left arm.
Right handed. I guess there is an inherent bias to overcome there, but it seems like more than just that.
I'd love to find a PT who really knew swimmers.
