Did you think about sex when you were reading the word swing?
No, silly, this is about the part of our bodies that hangs down from the shoulder and helps us keep balance as we move!
Once we heard from a woman who ran marathons that it was very important to use the arms whilst running: we have to keep the momentum.
Momentum connects to Physics...
According to http://www.physicsclassroom.com/Class/momentum/u4l1a.cfm, keeping the momentum is not diminishing motion.
It is actually the capability of motion that has already been changed into almost movement, just like a battery that has already been charged (notebook), and can last for about two hours transmitting the same amount of power to the system.

We may destroy the almost movement, which is on its way to the two-hour mark: we drop water over the notebook...
http://www.wilkpt.com/Articles/Running&Fitnews/armswings.html brings the basics: Try to keep a 90-degree angle, do not let the elbow pass the spine, etc.
As for the hands, it seems that the majority of the people who write about the topic agree that we should not keep them tense, but they also advise us not to have them lose or moving.
Michael Johnson is an impressive figure. In http://www.youtube.com/watch?v=zOZajO0rCP4&noredirect=1, he keeps his hands closed and his thumbs on top of them, and that is the standard recommendation.
Ben Johnson, another impressive figure in running - sprinter - does the same: http://www.youtube.com/watch?v=_SKlNUbyhwA.

One of the most important insights that people have shared with us is that if we move our arms in a slower manner, our legs will move in a slower manner too.
