    burning thighs during sprints?

    Is it normal to have a burning sensation in my thighs DURING a sprint?
    In my school athletics team I did 100 metre sprints and my thighs don't hurt at all during or after the sprint. I also wear Skins half tights which help compress the thigh muscle areas. I wear the half tights under my cycling shorts so could lactic acid build up be ruled out? (http://www.skins.net/au/en/HowSkinsWork)

    How could I sprint for longer? Or do I need to live through the pain?

    thanks.

    It is normal to get some kind of lactic acid burn in your muscles in a sprint. I don't know much about the Skins tights but i find it hard to believe that they could totally eliminate lactic acid muscle burn. Now if that lactic acid burn is too much then a likely candidate is a lack of minerals. Magnesium and Potassium would be up there on top of the list.

    all good advice

    I wouldn't worry about anything unless you cramp and have to stop. Then you may investigate minerals and electrolytes. But if you snap out of it and can keep riding, then the pain is just something you need more of. pain is weakness leaving the body if you don't seize up and cramp.

    try Spinervals 3.0. It has some 1 minute intervals where you go 100% a lot. and true 100% at one minute, and 5 in a row like that, you will feel pain everywhere and want to cry. but then next time you are on the bike you just float by all the posers
    who don't crush themselves as hard....

    incorrect.

    to get better you must endure discomfort. a lot of discomfort. if not, then you are NOT doing it right

    to go as fast as possible you better bet your a** it hurts.




    so back to what I said...htfu and go harder longer the next time.

    your face, your teeth, your throat, lung, your ears, your back and butt and legs and feet should all feel uncomfortable and your feet should be about to pop off both pedals. then you are 'sprinting' correctly and are really riding at max.

    It's not all lactic acid either. You are calling on muscle fibers in your quads that aren't use to the hard work. Intervals and hard training help.
    You're just trying to start an argument to show how smart you are.

    Trust me on this one, I've sprinted against, (and lost to) some of the greatest sprinters of the 80's hundreds of times. I know what a sprint feels like, and I know the biomechanics behind it.

    sounds like you don't ride hard enough.



    simple

    ride friggin hard, basically always, and take yer rest days and ez spins to recover


    ha cripes I sound like the reincarnation of ryanf I better stfu myself

    OR a newbie who doesn't know if this sort of pain is 'good'

    dude the pain is OK. after a long ride of hammering along, and the final sprint, your legs
    are probably full of acid and just below cramp threshold, and sprinting will hurt for sure.

    but you will know if the pain is something to worry about if you start to slow down
    and not want to ride.

    interval training can blow your legs up and then the next day, or 2 days after, your legs might
    hurt for the first 10 miles and you have to just warmup and push though that. if you hammer
    though the pain it should go away and then you can keep hammering. if not, then you may be
    overtrained and you need to do easy spins for one more day

    sprint enough and do leg work like squats and eventually you legs will not hurt in sprints, they
    will be strong enough that the only limit is not leg pain, but breathing. your lungs really should
    be the only thing that burns when your legs are powerful and you sprint. the legs are not the
    limit at this point it is aerobic capacity. squats and iso squats can help


    anyhow......don't worry about it...harden up and hammer ! if your joints make noises and you
    start to walk with a limp then something is wrong, prob need to back off a bit for a week.

    I dunno. I'm a pretty good sprinter on the bike. Guys 20 years younger than I with legs like "real riders" can beat me, but that's about it. My legs don't burn. When I run out of sprint, they just stop working. That's the reason that you have to know your point intimately for every degree of exhaustion. You have to know where to start or they'll go by you at the line. You all know that. It's not the pain that stops you. If you're really going, you don't feel anything except the animal hunger for that line or sign or whatever. It's true that you do have to pay attention. You don't want to hit anything or come totally unglued and come off the bike, but other than that it's just a blast.

    So, why does Chad hurt? He's done a lot of track sprints, so he knows what that's like. I wonder if he's ever run 10,000 meters, rested for 2 minutes, and then sprinted 100 meters? Now that's pain. It's just biking the distance. More lactic acid clearing intervals, like pyramid intervals or 1 minute max, one minute easy, that kind of thing. So that's what I'd say. Also try sets of 45 second uphill "sprints," which aren't real sprints, just max efforts, with 5 minutes between them.

    It partly depends on whether he's trying to become an all-round rider, or trying to specialize. If he wants to be an all-rounder, than he's got to work on converting some fast twitch into type II. I think really long climbs, like 30 minutes at LT, are good for that. After the first few minutes, your fast twitch are cooked. Maybe what's going on is that his few slow twitch fibers are getting overcooked. That would hurt. Someone else perhaps can speak to the training necessary to specialize in the sprint.
