A recent study at the University of Wisconsin found that runners who shortened their strides (and increased their stride rate) by 5-10% bounced less, landed closer to their center of mass, and produced lower braking forces against the ground. The shorter strides also reduced forces on the runners’ hips and knees.
This confirms my personal experience. I shorted my stride and increased my stride rate a few years ago and it’s made a big difference in my running. I feel that my running is more efficient and that my shorter stride has helped prevent shin splints. It may have also allowed me to run marathons, despite the fact that I’m missing part of the meniscus in my right knee.
Try shortening your stride for a week and let me know what you think in the comments.
