The reason I decided to copy paste this article was, Sometimes when I am having my 10K run, After 5-6 Kms, I start feeling lighter, and it seems I have no control on myself. My hands and legs continue their motion and I just helplessly witness the "Flight".
Maybe this is what happens to me sometimes :
The runner’s high: Every athlete has heard of it, most seem to believe in it and many say they have experienced it. But for years scientists have reserved judgment because no rigorous test confirmed its existence.
Yes, some people reported that they felt so good when they exercised that it was as if they had taken mood-altering drugs. But was that feeling real or just a delusion? And even if it was real, what was the feeling supposed to be, and what caused it? Some who said they had experienced a runner’s high said it was uncommon. They might feel relaxed or at peace after exercising, but only occasionally did they feel euphoric. Was the calmness itself a runner’s high?
The runner’s-high hypothesis proposed that there were real biochemical effects of exercise on the brain. Chemicals were released that could change an athlete’s mood, and those chemicals were endorphins, the brain’s naturally occurring opiates. Running was not the only way to get the feeling; it could also occur with most intense or endurance exercise.
The problem with the hypothesis was that it was not feasible to do a spinal tap before and after someone exercised to look for a flood of endorphins in the brain. Researchers could detect endorphins in people’s blood after a run, but those endorphins were part of the body’s stress response and could not travel from the blood to the brain. They were not responsible for elevating one’s mood. So for more than 30 years, the runner’s high remained an unproved hypothesis.
But now medical technology has caught up with exercise lore. Researchers from University of Bonn in Germany, using advances in neuroscience, say that the folk belief is true: Running does elicit a flood of endorphins in the brain. The endorphins are associated with mood changes, and the more endorphins a runner’s body pumps out, the greater the effect. Leading endorphin researchers not associated with the study said they accepted its findings. NYT NEWS SERVICE
CHASING EUPHORIA: It has finally been proven that endorphins exist! Getting a high during running or other intense, sustained efforts isn’t a myth anymore
