Just on the subject of knees, ive had what i would call chronic knee pain since its been going on for a while now. I assume it's due to a riding issue of some sort but it is hard to pinpoint exactly what's going on and how to fix it. Haven't ridden much in the last few months, been trying to rest up and allow it to heal but i think it's one of those things that will take time to get better.
Went to the doctor a little while back, who said is it probably a bit of wear and tear arthritis. Could be a bit of Osteoarthritis. According to the web it is a condition once thought to be due simply to wear and tear on the cartilage of a joint. Been googling around and come up with what could be something known as movie goers knee or Patellofemoral pain syndrome. Basically whenever i go to get up of a chair or my bed if is uncomfortable, as well as climbing stairs. Basically ive had a lot of trouble with my feet (had stress fractures a few years back). Had to have an op back in 2009 to remove some bone fragments from by ankle.
I was taking Voltaren for a while, and that was the only thing stopping by body from basically aching all over. If i missed one tablet boy would i know about it lol. Lately my doctor has been trying other anti-inflammatory tablets to try and get it under control but not much success so far.
Maybe i had my seat on my mtb bike a bit too low. Its a bit hard to gauge the exact correct seat height with duel suspension as when you sit on the bike obviously it goes down a bit. Its probably an overuse injury due to incorrect technique. Could also be a muscular imbalance from not stretching enough.
So frustrating as i was keen on doing some races such as the Capital Punishment, Rocky Trail GP races and the Beechworth 6 hr, but there will be no chance of that. Just got to try and get this all fixed up somehow.
im just expanding on what Blakz said about riding position and pedalling technique.
Also on stretching, i've met lots of awesome riders who barely stretch at all, then others who say you should stretch for as long as you can stand the boredem. I reckon, it cant hurt, i do it and it definately helps my recovery. I've never stretched prior to riding though personally. Maybe when i get older ill need too!
Yeh i think the best bet is to spin for 5 minutes or so before you go riding and do a few stretches after you finish. There's a section about stretching called 'tight on the bike' in an issue of AMB from a while back which goes through some stretches you should do, ideally after exercise. Takes around 15-20min or so.
