Ya, I find that kind of hard to believe myself. If this were really an issue, then lots of swimmers turned triathletes would have her same issue but AFAIK that is not the case per se. The whole reason I even bothered watching this video was b/c I wanted to see if they were actually talking about swimming breathing affecting running, which seems like a really big stretch IMO. :)
Itâ€™s interesting as I pretty much had the same injury as her a few years ago. I swam in college and typically breathe to one side. Occasionally I breathe to the other but itâ€™s probably an 80/20 or 70/30 split. I donâ€™t think this caused my injury but it definitely affects my run form and muscle activation. Iâ€™ve always felt my one side is asymmetric while running and itâ€™s something I am constantly thinking about during my runs.
Did your injury occur on the same side that you breathe on or on the other side??? And which side do you breath on???
I think the point of breathing one side only is it is a red flag to asymmetry. Why would you breath to one side if you had proper body symmetry and balance. Every one side breather I have watched and/or worked with does not complete the needed rotation which allows breathing to both sides. So it is not about breathing to one size causing the body imbalance, it is about breathing to one side demonstrating an imbalance that could result in numerous kinetic chain problems.
