24-Contreras B, Beardsley C. The Optimal Athlete: Sprinting. Almost anything that needs to be calculated can be thanks to the huge strides in science and technology. The different calculators available in the market measure and give accurate results and implications of how a certain thing works and the ways in which it can be made to work or perform more effectively. When you watch an athlete attempting to accelerate faster they will be operating from a position of compliance as its called in biomechanics, where the muscle will be under tension at a longer or more stretched position. Of the 11  athletes total, 9 of them ran under 10.00s in at least one of their races. Frequency. To get faster, one or both components of the stride must increase. You then hold this pace for the second portion of the stride. 77-Salo, A.I.T., Bezodis, I.N., Batterham, A.M., and Kerwin, D.G. With that being said, there are specific drills and ways in which you can focus on each skill to ensure that you are making progress. 2005. Recall the Usain Bolt took 4 less total steps than his competition in Berlin where he set the world record in the 100 meter dash, and we also took a total step count of LaMichael James when he recorded an unofficial 4.27 second run at the NFL combine years ago. They are broken into three sections; the first section is used to accelerate. Stride rate describes how fast strides are taken and the units are strides per time. But forcing a longer stride does not necessarily means that you can faster. Also, make sure you are not over striding. STRIDE LENGTH VS. Stride frequency relates to the time factor, while stride length relates to the distance factor. Improving running cadence means increasing the number of steps you take each minute. International Journal of Sports Medicine and Coaching 6: 479‐494, 2011. Stride length is the distance covered per stride … units being distance per stride (e.g., meters per stride). Your mention of the 2000 Weyand et al study of faster running speeds is only partially correct, "sprint speed was partially determined by vertical Ground reaction forces." 48-Clark, M, NASM Essentials of Personal Fitness Training, Baltimore, MD, Lippincott Williams & Wilkins: 2008. 78-Majumdar A, Robergs R. The Science of Speed: Determinants of performance in the 100m sprint. As an example of the potential performance benefits of increasing your stride rate, an increase from 170 to 175 steps per minute equates to about eight meters per minute or … A person’s stride length can vary depending on their height, hip mobility, and general fitness. Generally, strides per second (aka, Hertz or Hz) or strides per minute are used for units. The other concern is one of eccentric strength. Running speed equals stride rate times stride length: Speed = Stride Rate x Stride Length. Stride length. I discuss Usain Bolt, Tyson Gay, and some of the best sprinters of all time. On the other hand, Debaere and his team found that the difference between stride rates between  sprinters at the beginning of a sprint was 95% of the stride rate at maximum speed. However, there does not seem to be a clear consensus, and studies seem to be split on which one is more important at an ELITE level. In adult subjects over age 50, at self-selected speeds categorized as slow, normal and fast, step length and step frequency decreased with age at all speeds. It all goes back to power ladies and gentlemen and how much you either have or don’t have if you want to run faster. The most efficient stride length is the innate one – the one you feel most at ease with. Perhaps because it is a relatively easy fix compared to stepping up your stride length. Researchers came to the conclusion that some of the runners relied upon greater stride length compensation while other relied on stride rate. Stride rate and running cadence has a strong correlation to your foot strike and running gait. The difference between the top runners and the others was that the best runners took longer strides. Speed = Stride Length x Stride Rate is an incorrect and outdated equation. The difference that makes the difference for the elite is their stride length. It is approximately 2.1 to 2.5 times leg length. Heel strikers are more likely to lock up their knees, and put added pressure on the body potentially causing injury.
