    Can be caused by a few things...simplest cause though....do any intense activity that involves shunting of blood to the musculature and away from the internal organs...for internal organs read stomach...and bingo...there's your breakfast, lunch or dinner on the track.

    You also get a massive surge of endorphins....which can cause you to puke...the same ones that make people puke when they get nervous...whether your are running flat out...or standing back stage about to belt out I'm Every Woman on X-Factor and thinking that you want to run flat out....those chemicals are telling your body to purge the cylinders before taking off.

    I hope that wasn't to sciency :)

    Thanks. Not too sciencey at all.

    Another cause of throwing up after a strenuous exercise is hypoglycemia - dramatic drop in blood sugar levels. Hypoglycemia is usually linked with diabetes but the same word is used for those who do not suffer of this illness and just get into the stage when almost no blood sugar is available. After your glycogen stores are exhausted, your body needs some time to adjust and start to process fat as energy source. If you are not trained well, or your diet is not good, or you are impaired by lack of sleep, you have hungover, you are sick or so - your body fights with this adjustment and that's where the hypoglycemia occurs. Your body's sugar levels are so low that you are for (up to few) mins with almost no source of energy at all.

    The signs of hypoglycemia are dizziness, confusion, fatigue, headache, trembling, paleness, etc. Puking is the next stage by which your body is basically trying to tell you stop what you are doing because apparently something is wrong with you.
    If you do not stop, the condition will worsen by dehydration - that is the first, direct result of puking. If you still continue your exercise you usually faint, and that is again the result of your body's protective reflexes: it wanted you to stop what you were doing because apparently you are pushing your limits too far.

    Unless you are top athlete who is paid for getting the best out of him/her, you should not get to 'puke stage' at all. It does not do you any good at all - it just weakens you and takes away that great feeling exercise is leaving you with in normal conditions.
    Therefore the training always should be gradual so your cardiovascular abilities increase with time, as well as your body's glycogen and fats management.
