Hey,
Is it about muscle pain. Please, I want to know . I am suffering from heavy muscle pain these days.
Something you might try is wheatgrass or spirulina -- they're loaded with food based antioxidants. You should also make sure your food has sufficient Vitamin C.
I'm not your doctor, I don't know, but I doubt it. But it sounds like you're not eating for intense exercise. Are your meals balanced? Do you eat enough complex carbs for the fuel for intense cardio? Do you eat enough protein to recover afterwards? And again, what are you eating or drinking to get your electrolytes? You know, Gatorade, but hopefully something more healthful, like bananas and apples. As for lactic acid, antioxidants help with that. Do you get enough antioxidants, which come from colored fruits and vegetables? I'd guess your problem is either dietary or psychological, meaning you're getting sick from your running because you don't believe you can do it. The brain can do weird things. When I was in junior high we had to run the 600, which is really short but seemed very long at the time. I always got nauseous afterward, and so did many others, but we all grew up to realize we could run all day without a problem. It was just believing we couldn't.
I eat a small light meal about 2 hours before. Do I have some kind of disease or disorder?
You're hydrated, but are you getting your electrolytes in the proper balance? What do you eat before and after your runs?
