Back to the Black Line

Remember this?

I took a few days off after my cold-water revelation last weekend to decompress and to abuse myself by doing a 180 - running in a Midwest heatwave marked by several "heat advisory" days this week. (Note, running is my other zen sport, it's my self-medication.)

When I DID get back in the water, I was reminded of two things: (1) the task at hand, oh so long ago, before the Glastonbury festival, before whipping myself into endurance-racing mode - i.e., re-learning proper technique - and (2) teaching my body how to survive, or thrive, in cold water. Now that I think about it, one of these things may benefit the other.

Here's my thought: if I learn how to swim better, I should be faster, right? And if I'm faster, I will be out of the cold water quicker - right? Yeah yeah, I know I still need to learn how to SWIM in cold water because I certainly haven't forgotten how quickly hypothermia sets in... I'm sure there's an equation for conduction or convection I probably (should have) learned in heat transfer class when I got my engineering degree.

I survived for more than 5 minutes.

I was reminded of my crazy English swimming compadres in London in December (remember that?). They were able to swim in sub-50 degree F water for long periods of time because their bodies had been slowly acclimated to it as the temperatures dropped. If you remember my blog posts about that experience, I noticed a difference in my own ability to withstand cold water even after the second time. And in my previous post, I told you about the advice from Ocean Games race director and open-water swimmer Corey Davis - his recommendations were to take cold showers and extend my open-water swim season into the colder months.

So, that's the plan. But in the meantime, while the water is still warm, I need to determine how to perfect my swim stroke so that I spend less time in that cold water. 

The last thing I did with respect to THIS goal was to get video of my swim stroke underwater. Here it is:

And, whoa, talk about revelations! There's a LOT to improve on. I may have the high-elbow thing going for me, but my underwater pull is ridiculously wide. There's not nearly enough water being grabbed and pulled back. Ineed to get my forearm under my body so I'm moving through a smaller area. I have also recently realized that I swim faster when using a pull-buoy, which I think might have something to do with my right arm not going as wide and breathing on the left.

But I needed more than hunch. I needed data. I'm a scientist after all.

So... here's my (pseudo-)scientific analysis...

I first noted that if I don't think about it, I breathe naturally on my right without a pull-buoy but naturally on my left WITH one. I've been baffled by this for years (since I started swimming again after more than 15 years away from the sport). When I was a competitive pool-swimmer, I could bilateral breathe with no change in my stroke. But now, it's a struggle to breathe on my left. WITHOUT a pull-buoy. I am convinced this means something - like one whole side of my body is weak. 

I started experimenting in the pool in the past several weeks. At the end of my workouts, I swim 50s with and without a pull-buoy and concentrate on what my arms and legs are doing. Here's what I've found (and it's extremely annoying): without a pull-buoy breathing naturally on my right working very hard to keep my body and kick streamlined, my 50-yard time is within one second of my time with a pull-buoy breathing naturally on my left. The difference (i.e., the annoying thing) is the very little amount of effort I have to put in while swimming with a pull-buoy. 

What could possibly be going on here? Are my legs or my kick causing massive drag? It's hard to believe that I'm not getting at least a tiny bit of propulsion from my kick. Is my pull different when breathing on different sides? Am I in a different position in the water?

After studying it the best I can (it's not easy to study with detachment from an internal state), it does, indeed, feel like I'm getting more from my pull when I breathe on my left. I come up with two pieces of evidence: being right-handed/right-dominant, my right arm is stronger, and when breathing on my left, I rotate in a way that keeps my right arm under my body instead of way-wide like in the video. Further study Also revealed to me that I turn my head to breathe at a different point in the stroke cycle on each side. Breathing right, although it "feels" natural, it's more awkward to the stroke and there's an obvious momentary lapse in my kick.

And therefore, this week, while I recover mentally from the failed race finish, I've begun doing drills to fix my bilateral breathing and sync my kick. It's not natural just yet, and it probably won't be for a while, but hopefully I'll have something to show in a month or two.
