Peroneal muscle fatigue - what am I doing wrong?
 
Hi all. OK here's my problem - the peroneus muscle in my lead leg KILLS me by the end of the day. For those of you who don't know, the peroneus muscle runs from just below the outside of the knee and attaches to the outside of the foot. Google image search peroneus longus or brevis if you want to see a picture.

Anyway, I can feel myself constantly contracting this muscle when I'm boarding and I think I'm doing it for stability because when I consciously try and relax it I do feel a bit less stable, though I'm not sure why. At first I thought my boots were too big and that maybe I contracted my peroneus to keep my foot more securely in the boot, but downsizing boots didn't help that particular problem at all. So then I tried switching around my bindings. I went from 15 in the front and -12 in the back to 0 and 0. That didn't help either. So then I tried keeping my back leg at 0 and putting the front leg to around 12, which maybe helped a little but not much. Then I tried bringing my bindings a little closer together and I think that may have helped a little bit as well.

But the problem still persists so now I'm thinking it might just be a technique issue...like I've gotten into a bad habit or something because the strain seems to get a little better if I consciously put more weight on the front of my board, like maybe 60/40. But this also makes me feel a little more out of control. Maybe I just need to practice this? How much weight should I be putting on my front foot? Another thing I'm trying to do is stand in such a way that I feel the board solidly underneath me with both feet if that makes any sense - like straight up and down. But when I do this I feel like I'm about to fall backwards. I know I'm making myself sound like a beginner but I've been boarding for 10 years and I'm actually pretty good. I think I just must have acquired some bad habits somewhere along the way.

A friend suggested that I try to angle both bindings forward at around 25 and 15ish which is what I'll try next unless you guys have some better ideas. Has anyone else had this problem before? It's very annoying.

Thanks in advance!

As far as checking for bad habits, a video posted up here (people here are awesome about critiquing riding), or a payed lesson on the hill is probably the easiest way to identify and fix what is going on.

In the tips and tricks section there are some really good back to basics videos that I sometimes look at if i'm feeling like a refresher.

Going for a forward stance is a bit extreme. +0/-0 is also not such a good idea. +15/-12 is super normal and unless you have something a little abnormal going on with your legs and feet it shouldn't be a problem... hard to know!

whats your stance width? I have a feeling its too far apart..

aj327 01-18-2012 05:19 PM

Thanks for the quick response. I was hoping that this was kind of a common problem with a known solution. I'll get some video footage and upload it to see if that helps. In the meantime if anyone else has (or has had) this problem, please chime in.

Yeah my stance width was probably to wide because when I brought it in a bit it did help. Maybe I'll try bringing it in a little more.

Have a look for some general stance guidelines for stance width. See if you are in the ball-park with what you are riding now :thumbsup:

Have you ever considered a binding with canted footbeds? I don't have any experience with them myself but I've always read that they help with knee pain. Perhaps this could help with the fatigue as well. Maybe someone with some experience can chime in.

I am currently snowboarding with 1 subluxing peroneal tendon on my lead foot, and a recently repaired peroneal subluxing tendon on a rear foot. I tore the retinaculum in both ankles on different occasions due to shallow grooves. What I've done to deal with the problems are to buy stiff boots, I use 32 focus boas, I tape the ankles to limit eversion, and run canted beds on my ride bindings. I also did a bunch of PT to strengthen the ankles. The peroneal tendons on my lead foot still occasional snap painfully, and they are sore at the end of a hard day, but it isn't too bad to just deal with the pain with some advil. Not sure if that helps but you gotta do what you gotta do. I also run a decently wide stance for my height.

i have consistently been told that the more weight on the front foot the more control you have, in fact i believe especially when turning you shouldn't really use your back leg it should just follow your front foots lead. Have you tried canted footbeds? sounds like your back leg may be being stressed because you are stretching that muscle beyond its comfortable range. Canted footbeds may lessen the stress from that back leg as it changes the angle that your legs are in and would effectively shorten the muscles on the outside of the legs (back in particular). Something to think about, also stretch......ALOT

didn't realise someone already suggested canted....oops

aj327 01-18-2012 07:23 PM

CJCameron11 - actually it's my front leg that bothers me. My back leg feels totally fine. The canted bindings do sound interesting however. Too bad though cause I just ordered some Burton Missions to replace my Flows to see if that would help. My Flows can't be positioned toe side enough so my heel ends up hanging over the edge more than my toe does. Maybe I'm grasping but I'm trying to fix any little flaw that I can see. If I cancel the Missions what are a good pair of canted bindings that you can suggest?

LuckyRVA you said canted bindings help with knee pain but I don't have knee pain. I just seem to always want to contract my peroneus for stability. And after about half an hour on the slopes I can feel fatigue starting to set in because I don't seem to be able to give it much of a break. It's either a habit I'm going to have to try to break or (hopefully) I can fix the problem by adjusting my gear or stance somehow.

Redlude97 - interesting that you suggest the 32 Boas because those are the same boots that I have and I love them. They haven't helped with the peroneal issue but the double boa system is so easy to tighten and loosen - it's great. And super comfortable too.

In terms of putting more weight on the lead foot, how much is the prescribed amount? Is 60/40 about right? I don't know if I have a problem leading with my back foot so much since usually I just rock from toe to heel (or vice versa) to initiate the turn.
