Things I learned about my knees
Oct. 25th, 2008 09:55 amGetting studied on Wednesday, they measured the strength of my knees and my grips. That way if I go on the experimental calorie reduction I can come back in a year and see how much I've wasted away. Right now, I think I'm pretty strong. I learned I can exert 160 Newton-meters of torque at the knee kicking forward through the quads, and 130 Newton-meters of torque pulling back through the hamstrings. The grip device reported "44", which I'm going to guess is linear Newtons of force.
The interesting thing about my knees is that a couple years ago when I was in physical therapy for knee trouble, one of the things they told me was that I needed to strengthen my quads, which didn't make much sense to me as I thought they were pretty strong from biking and other things. What they told me on Wednesday was that the normal ratio of strength on that joint is closer to 2:1 and they were surprised how strong my hamstrings were. They said that this imbalance sometimes causes knee pain. Aha! Now the comment about my quads from years ago made sense.
So, there are a few exercises from the old PT routine that I may resume, and I've been thinking about my bicycling technique and whether I can change the way I use my muscles to pedal. But I shouldn't do too much. It might throw off the study.
