Treadmill running with heavier shoes tied to slower race times
It makes sense that running with heavier shoes on will cause you to exert more energy than running with lighter shoes. That was proven several decades ago. But does using more energy while running with heavier shoes translate into slower running times? That's also a yes, say researchers who designed a clever study to show that running times slow when running shoe weight is increased, even if only by a few ounces. Ref. Source 1e.
Very interesting tidbit of information. After reading it I went to get a feel for the weight of one of my running shoes compared to the other and there was a major difference. I need to start thinking about drag and weight next time I buy.
Unless one is racing, I don't see how that is particularly relevant. People running for the health benefits will actually do better with the heavier shoes for the most part.
In fact, if one IS racing, it would be of benefit for the racers to have two kinds of shoes. One relatively heavy to build endurance while training, and one light for final practice and the actual race.
Who wants to go slower when they can go faster? I usually jog, sprint run, and then jog again. I think the findings on it is good knowledge for the next purchase.
