    hi im doing sports science and have read that lactic acid has nothing to do wiv muscle soreness after excersise in this book. it says that its to do with repeated usage of the muscle fibres. this is new to me though i thought soreness was caused by lactic acid :confused:

    I can't give much help here, but anyway here goes. Lactic acid is produced when something stresses muscle fibres beyond reasonable levels. Thats pretty much all I know, and I'm pretty sure it isn't too precise, however... If you remember the flick A Few Good Men starring Tom Cruise, Demi Moore, Jack Nicholson. The private guy that got killed dies of 'acute lactic acidosis'. The story goes that they pushed a clean rag down the blokes throat, but pushed it a little too far. Thus the muscles in his throat suffered undue stress causing the lactic acid thingo. I hope that helps you a bit.

    Isn't it produced when the body respires anaerobically?

    -Eg -the body isn't getting enough oxygen so it respires using just glucose. Lactic acid is a product of this and builds up in muscle cells...

    Atleast I think that's right.

    yeah, that rings a bell. Though I really can't remember much about it at all. Just kinda learn things and put them to paper so that I can forget them again. Ever hopeful that I'll never need it again hehe

    When oxygen is not being taken in at a fast enough rate during excercise, lactate (lactic acid) is produced by the muscles as they respire using a different method of respiration (anaerobically). After the excercise is finished, due to an 'oxygen debt', areas which don't have enough oxygen are supplied with it (hence the continuing rate of fast breathing).

    *chuckles* my biology teacher spent the year trying to get pregnant. I can just about quote song and verse of the bloody topic now, including atrificial methods. and to think that we were supposed to be learning about plants, and the tropisms exhibited by them etc.

    Impressive Mr White. You never cease to amaze even a tired and haggard old soul like myself.

    Ur teacher is right i think...the whole thing with the oxygen debt is right too...but lactic acid is toxic in high enough amounts....so if u do too much exercise....the build up of lactic acid acts as a defence mechanism...causing cramp in the muscles.
