Shelby,
Well, I had a bad left leg like most guys here, and developed lots of problems like sciatica, piriformis syndrome, shin splints, ankle soreness, and even my metatarsals began to ache when I do sprints with spikes. People keep telling me I limp when I walk. Also, my hips swing all over the shop when I run anything over an hour. Calcanaeus bone of that heel also ache frequently.
Any way, to ans yr questions,
Yes, I have more or less dealt with the problem, but it is not something that just goes away for good. You have to constantly find a new balance in training.
I started by running some of my track reps in the clockwise direction (ie right turns), like 12 by 400m with every 2nd or 3rd rep run clockwise direction. Just by doing this I felt significant alleviation from my sciatica and shin splints. Of course u have to be fortunate enough to find a track where its not that crowded to use lanes 1 or 2 for right turns. The track I run on rarely has any serious trackers at the time I train (wh is like very early morning, b4 sunrise!) But I think u don't really have to worry much abt that detail....
I do single leg lifts like most of the guys on this thread, like knee extension, hamstring curls, leg press,1-leg squats, step-ups, etc, and when I cycle I do wht some triathletes do : isolated leg pedaling, where u basically alternate between each leg in doing the work and keep the other leg passive.
I also do 1 leg hops, and believe me u will really see how bad it is on this exercise. Initially my left leg/hip would just sink in real bad rearwards and I have difficulty balancing myself. I would always be tilting sideways. I also do bounding uphill and on flat grd (same for the 1 leg hops) and I would also be tilting left. But I started very conservatively and as my strength work caught up with me I felt more balanced.
One note abt the track work is that maybe one shd consider taking some of the reps off track, and alternate between off and on track in the same workout during some of the regular sessions. Once I did 6 by 800m doing the first rep on track counterclockwise to get the feel of race pace, then doing the next two on the road clockwise and straight, respectively, then returning to the track for a clockwise rep, b4 finishing on grass field for counterclockwise rep. I did this both for cross country and for track preps.
Consider doing this even for 800/1500 type reps also whenever u feel like your leg is losing it again. I know we need to be track specific when training for track races, but I think as long as u still do the really key sessions that r purely on track and run counterclockwise (ie left turns), u don't have to worry abt to being ready for track racing. Fr my experience, alternating between surfaces actually keep me feeling fresher. But not every one responds the same I guess.
I also eliminated some of my usual training loops and replaced them with out-and-back routes.
Of course I stretched like hell, doing all sorts of hip flexors/rotator stretches, hamstring stretches both one leg and two legs together (here u will see AND feel the leg length discrepancy, and the hip/groin/glutes area acting up!) Once when I tried the one leg hurdler's stretch my left side seized up, and I had spasms even in my lateral obliques!
I guess u have to manage it, as long as u want to be a tracker, or to train on track, like the athletes fr sports like soccer, basketball, squash, tennis, etc. I've heard of runners who don't even use the track but can race real well even in the 800m! I've even seen a sprinter doing a lot of his stride work and drills in the forest, even a month b4 his key race! And the fella won!
What I'm saying is that if u develop overuse problems u have to adapt and change. I know some coaches may not like what I've written, but the sheer number of posters here who suffer fr this leg problem reflect a worrying trend.The track is made by humans for the purposes of precision and convenience, and for spectatorship. But not with the human natural physiology on mind. But since we need to use it, let's be willing to use some good sense.
