    NYT: The ideal arm swing while running may be the one you’re already using, a new study of upper body biomechanics concludes.

    I've always used my arms for momentum when I run...pumping them moderately, more pronounced on the uphills and less pronounced on the down; keeping them close in, with my hands barely brushing my hips with each pass, not crossing a plane in front of the midpoint of my chest, and relaxed (like you're holding potato chips, my dad used to suggest); keeping my shoulders low, relaxed, and facing forward...and always breathing deeply. Running is about a lot more than the legs, or even the body. My former partner, a 2:18 marathoner, used to say that running a marathon is 10% physical and 90% mental.

    These "scientific experiments" had to be performed to prove common sense?

    The story just mentioned normal arm swing to counteract the motion of the legs, but didn't mention other benefits of deliberate arm motion. As mentioned above, pumping the arms going uphill takes some of the effort off the legs in movng the body uphill, and reverse arm movements can help slow the body when going downhill. On a hilly or long course [or both], having the arms do some of the "heavy lifting" is smart and efficient.

    Many times what has for decades been thought to be common sense has been demonstrated to be a mistake. I'll leave it to others to post examples if they are so inclined.

    At one time runners were advised to keep their arms completely relaxed and hanging loosely by their sides the theory being that arm motion wasted energy. Now it has been demonstrated that normal instinctive arm motion while running actually improves efficiency.

    Yep, just like no scientific experiments were required to prove that the earth is stationary and the stars/sun/moon rotate around it, since "common sense" tells us we're not moving but they are. icon_wink.gif

    Won't be doing any running unfortunately, just slipped in the kitchen and sprained ankle. Funny I just read a story on how being too healthy can be bad. Was going for some healthy food and slipped.
