Sorry for the radio silence-a combination of things has kept me off the bike a lot more than I would like. In the intervening weeks, I've been having physical therapy (ART and Graston) for my hips. Briefly, my right hip was so tight that there was virtually no rotation in it, which had a bunch of consequences--the biggest one being that it made running impossible without quick and decisive injuries (calf strains, IT band, you name it). (The left one was not much better, but the right one is really bad). In any event, that has since loosened up considerably.Originally Posted by RapDaddyo .
I'm curious about your reduced power in the aero position. If you ride at your FTP in the aero position, and you have to back off sooner than expected (based on your road bike fitness), what are the symptoms? What appears to be at its limit -- legs or lungs? Do you actually have any discomfort beyond mental discomfort? If you have discomfort in your legs, where -- quads, hams, knees or calves? If you are making all of your power from the waist down and almost entirely with your downstroke, you should have no discomfort from the waist down in the aero position. But, if you are not rotating your pelvis correctly, you could be impeding your breathing, which would reveal itself in your breathing in the aero position.
After being pronounced cleared to run, I went for a 2-hour ride with this exact question in mind. The short answer is that if I have to guess, it's pelvic. Sadly, I'm not sure exactly what proper rotation feels like (and if there are any pointers you might have to drill that, I'm open to listening). In any event, all I can say is that when I try to flatten my back, relax and push from my gluteus, it feels like it's easier to breathe, the pain in my quads goes away, and the power jumps 15 watts.
