Teammates – I thought some of you might be interested in this. In preparation for the major races coming up at the end of the season, I wanted to put a real number on my percentage of body fat - power-to-weight ratio being so important for our typically hilly road races. I thought I would have to head over to San Jose and pay a lot for this so I’ve never done it. Silly me.
It turns out that Dominican Hospital’s Center for Lifestyle Management right over on 610 Frederick Street in Santa Cruz does it and it only costs $79 (total, no tax). You call 831-457-7077 and make an appointment. Eric Hand was the physical therapist who did mine (his sport is beach volleyball). It took about an hour. First he weighed me and took my height. Then he did a skin-fold caliper test and then weighed me in the water tank.
The underwater weighing was interesting (the photo gives you the idea, but that's some other facility, not Dominican's; should have brought my camera).
You sit in a hanging chair submerged in the water tank. The chair is hooked to a scale overhead and you bend over and dunk your head and shoulders so you’re entirely under water. Then you have to exhale completely to get a true weight. That’s not easy, so they weigh you over and over. We did mine 4 times after which I felt like I’d done 100 sit-ups.
Once the weighing was done Eric crunched the numbers on his computer, went over the results with me and gave me a nice printout with my target body fat and weight for optimum racing performance. With this number I can finally stop worrying if I’m too fat or too thin (I’m not telling) and train with the right number as my target. Hope you find this information useful,
