As participants ran at their regular training pace, motion and force data were captured, and the data were then analyzed and correlated with age. DeVita and his team looked to examine the biomechanics of a set of healthy, recreational runners between theĪges of 23 and 59. In a follow-up study published in Medicine & Science in Sports & Exercise in 2016, Dr. Stride length was found to be 4% shorter in elderly adult walkers compared with young adults.

Young and elderly adults walking at the same speed. The Journal of Applied Physiology, Professor Paul DeVita and his colleague Tibor Hortobagyi set out to examine the joint torques and powers of There are a couple of studies of particular note relating to age and step/stride length. It's therefore worthīearing in mind that steps will vary depending on what you are using to measure them. In research, it's common to use more accurate devices such as actigraphs. As an example, both Fitbit and Apple Watch have their own proprietary algorithms thatĭetermine what constitutes a step, based on acceleration. The definition of a step also varies depending on the measurement tool.
