I have a question about sprinting, warmups and hamstrings.
I presently walk, jog, run, skip, jump, kick, accelerate (briefly), you-name-it for three laps as part of my warmup to doing 400m sprints. The one thing I DON'T do is static stretching, because I have it in my mind that that's not a good thing to do before sprinting (and to say the least, information on the web is conflicting and confusing). My first question is: should I do static stretches?
(I do static stretches as part of the cool-down, by the way).
In spite of what I do (or don't do), as a warm-up, I have recently started to suffer a hamstring issue in my right leg: it gets sore later during the day I sprint (no pain or stiffness during sprinting). The soreness (which limits range of motion - it gets quite painful to stretch the hamstring) can stick around for several days.
I stopped doing 100m all-out sprints, and instead started doing 400m sprints - in the hope that the peak intensity (and thus stress) would make it easier for my legs and such. It hasn't.
I went to see a Chiro about this (one who allegedly has 30% athetes as patients). He found my knee a little compacted, and my pelvis a little out of alignment. He straightened me out - I "responded well" to treatment. He said it should fix the hamstring issue and also hopefully improve a "click" in my right knee, which I've had for coming on for a year now, but which has never hurt to date anyway. The Chiro's work has apparently made no difference - my hamstring still gets sore at the top of my right leg, and my right knee still clicks, especially when I straighten the leg when standing and turning to my left.
I would really like to continue doing sprints - 100m, 400m - pretty much any ind really, as I just love doing them, but I also don't want to screw myself up.
My second question is thus: do you have any suggestions as to what I can do to imrpve any aspect of my situation on hamstring and/or clicking knee?
