stride rate vs stride length

Sinopsis

The longer the stride, the faster they run. First, the 2.1-2.5 times our leg length statement is  impractical. Many recreational runners think that speed should be a concern only to elite runners, but everyone can benefit tremendously from increasing their speed. It’s even more simple. Unfortunately, this is not true for at least three reasons. Here are two of the best drills for remedying stride length outside of just common verbal cues: Secondly, the length and pre-stretch that you occur during the first few steps is going to ultimately dictate how your posture and form will unfold on the steps that occur afterwards. Another study on this topic comes from: Majumdar and Robergs in 2011 called "The Science of Speed: Determinants of  Performance in the 100 m Sprint. Just don’t be harsh on yourself if don’t notice any instant results. Running speed equals stride rate times stride length: Speed = Stride Rate x Stride Length. The table includes velocities from 7.50 to 12.50 m/s. To get faster, one or both components of the stride must increase. They are broken into three sections; the first section is used to accelerate. The difference that makes the difference for the elite is their stride length. They reported that male sprinters rely more on stride length, while females rely on greater stride rate. Stride length, stride rate, and ground contact time. 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. So stride rate is how often we take a stride or step, and stride length is the amount of ground we cover with each stride or step. The average stride rate was greater for QH than for Tbred (2.88 vs 2.34 strides/sec; P<0.0001). In fact, when you improve your running cadence you will be able to lessen the braking effect and your running form will start adjusting automatically by taking up a stride length that is appropriate for your cadence. The stride rates were also used to determine average stride length by factoring in length of each race. 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. 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. Increasing your stride rate by 10%, say, from 160 to 176 strides per minute is much easier than lengthening your stride by 10%. Johnson, however, ran a much more controlled race and he was able to cover the last 100m in 11.52; much faster than others. Stride Length – All other numbers in the table are stride length, measured in meters, for the corresponding velocity and stride frequency. Shorter, faster strides allow you to run more efficiently with less impact on your joints. Improving running cadence means increasing the number of steps you take each minute. Stride length specifically, is associated with power off the ground. A person’s stride length can vary depending on their height, hip mobility, and general fitness. Research has concluded that most elite runners have the same running cadence per minute. In Medicine & Science in  Sports & Exercise, 2011, Salo, Bezodis, Batterham, and Kerwin analyzed 11 elite male  100  meter runners from Olympic, World, and European Championships. We have seen it is dangerous to increase your stride length by forcing things. Just like in the Weyand study I shared with you at the very beginning of the article. Too few strides/min (less than 180ish) may result in a longer stride or heel striking position. 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. The hockey stride has been described by bio-mechanists as biphasic in nature consisting of alternating periods of single leg and double leg support. Moreover, the difference between stride length was 10.3% initially and then 11.5% at maximum speed, indicating stride length as  the dominant feature for faster running. The final section is for slowly easing back down to either a walk or slow jog. The difference between the top runners and the others was that the best runners took longer strides. As you age, chances are likely your walking speed and stride length will both shrink a bit. Research has found that optimum stride length at maximum velocity has a high correlation to leg length. An elite runner counts about 180 steps per minute. Elite sprinting: Are athletes individually step frequency or step‐length reliant? Your stride length and the frequency of your foot strike determine your speed. Stride length is the distance covered per stride … units being distance per stride (e.g., meters per stride). Too few strides/min (less than 180ish) may result in a longer stride or heel striking position. An average runner will have a cadence of about 150 to 170 steps per minute. So stride rate is how often we take a stride or step, and stride length is the  amount of ground we cover with each stride or step. Stride Length Definition. Most training out there is geared towards training for stride frequency. I sent Alex a paper (Weyand et al., 2000) I had just read on the topic, and he posted a graph (see above right) from that paper showing that initial increases in speed seem to occur more-so by manipulating stride length, whereas achieving top speed seems to involve increases in stride rate once stride length … Heel strikers are more likely to lock up their knees, and put added pressure on the body potentially causing injury. But forcing a longer stride does not necessarily means that you can faster. The table includes stride frequencies from 3.90 to 5.30 foot contacts per second. 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. At the very start of a sprint you are starting from a position of literally zero acceleration, and regardless of how fast or explosive you are, the time spend on the ground is going to be significantly longer for everyone at this point, even the elite, so your focus should be on creating long and proper strides without compromising or disrupting proper front and backside mechanics at all. Results. A study of step length and step frequency. I’ve heard a lot of similar comments from other runners and coaches. Stride Length Definition. 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." I sent Alex a paper (Weyand et al., 2000) I had just read on the topic, and he posted a graph (see above right) from that paper showing that initial increases in speed seem to occur more-so by manipulating stride length, whereas achieving top speed seems to involve increases in stride rate once stride length … Logically, it would make sense that each runner work on their relative weakness to further decrease running times and increase speed. Even though stride length plays an important role to enhance speed, you should also increase your stride rate. The table includes stride frequencies from 3.90 to 5.30 foot contacts per second. Dr. Alex Hoffmann is the President of the College of Exercise Science. Speed = Stride Length x Stride Rate is an incorrect and outdated equation. What is really cool is that there is a strong relationship  between speed, stride length, and stride rate in sub‐elite runners. Research has found that optimum stride length at maximum velocity has a high correlation to  leg length. 75-Mann, R. The Mechanics of Sprinting. The two problems with strides that are too long: #1: A stride that is too long causes your foot to strike the ground out in front of … CompuSport: Primm, NV. 78-Majumdar A, Robergs R. The Science of Speed: Determinants of performance in the 100m sprint. 77-Salo, A.I.T., Bezodis, I.N., Batterham, A.M., and Kerwin, D.G. It is approximately 2.1 to 2.5 times leg length. If you’re doing a walk your stride length is very short, if you run it increases, and if you sprint for 100m that’s realistically about as long as your own stride length gets (without further training). It’s why many runners get frustrated and angry when they discover that they are actually slowing themselves down when they force a longer stride. Yet despite increasing your stride length nearly twofold, your stride rate--or how frequently you take each step--remains pretty constant. Journal of Strength and Conditioning Research 27: 116‐124, 2013. But forcing a longer stride … Question: Q: Calculating Stride Length and Rate I've read some theories that the optimum stride rate/cadence is around 88-90 strides (left and right step combinations) per minute and also have read others discuss optimum stride length based on height. Ok, explaining stride length is easy. Perhaps because it is a relatively easy fix compared to stepping up your stride length. The longer the stride, the faster they run. Galen Carlile Almost anything that needs to be calculated can be thanks to the huge strides in science and technology. Do your best to run as fast as you can with quick and short steps. In his excellent article Understanding Stride Rate and Stride Length, coach Steve Magness considers a study done by Enomoto et al. Velocity – The left column is velocity measured in meters per second.

The Optimal Athlete: Sprinting. Stride Length and Stride Rate are the results of increased speed not the causes of speed. You want to work on running fast but relaxed. Now that we have all of the science out of the way you can clearly see that for anyone who isn’t an “elite” sprinter and that would be the less than one percent in the world, everyone else is going to need to hone both products of acceleration and speed to be most successful. Velocity – The left column is velocity measured in meters per second. However, because stride rate and stride length are inversely proportional (as one increases, the other decreases), running speed can only increase if an increase in stride length is not accompanied by a similar decrease in stride rate or vice versa. Generally, strides per second (aka, Hertz or Hz) or strides per minute are used for units. There are two ways to run faster. Basically, strides can be done anywhere you find room to safely do about 15 seconds of faster paced running. Stride Rate: stride rate is measured by multiplying the stride length (distance) by how often you’re coming in contact with the ground (time). A study of step length and step frequency. A runner with a longer stride length will have a lower frequency than a runner with a shorter stride length when their overall speed is identical. In this case you just need to build awareness and cue them of a faster response to get the limbs moving the way that they need to be. RUNNING SPEED = STRIDE RATE X STRIDE LENGTH. To calculate your stride rate, use a stopwatch, watch with a second hand or other device to count the number of footfalls on your right foot for one minute. During this portion you gradually build your speed so that at the start of the second section you hit your top speed. So, your speed is ultimately determines by how quickly your stride rate, or frequency, is, and how much ground you cover in each one of those strides. Here are a few drills that you can incorporate immediately to help build this rebound effect and improve your stride rate! Stride Length. I then compare Bolt and Gay to some of the top runners in the NCAA and San Diego high schools. Sprinting Stride Length vs. Lastly, all you have to do is purchase or borrow a fully electronic timing unit and do your own research while utilizing different step counts and you will automatically notice that faster athletes regardless of their leg length will take less total steps, but create a tremendous amount of power and a much faster stride rate in the process. Heel strikers are more likely to lock up their knees, and put added pressure on the body potentially causing injury. Similar to a jump takeoff or the bottom of a deadlift, lunge, or squat. It takes more energy to run with larger steps, which is why Daniels says that fitter athletes tend to have slightly longer strides. In fact it can have a counter-productive effects. 37-Weyand PG, Sternlight DB, Bellizzi MJ, and Wright S. Journal of Applied Physiology 89:1991‐1999, 2000. “Stride rate is the number of strides taken in a given amount of time or distance,  while stride length is the distance covered in one stride, during running. As I said in my previous blog, all three athletes from the 2016 Olympic final were ahead of Johnson’s world record pace at 300m because they started out incredibly fast. This is where stride rate comes into play. Stride length varies from person to person, but an ideal running stride should be relatively short in length. The table includes velocities from 7.50 to 12.50 m/s. Another study shows a split between the two. Jamaica’s Athlete Sprint Training Program, Ankle Pain When Running : Cause : Treament & Strengthening Exercises, Half Marathon Training Schedule For Beginners. I’m sorry and it pains me to say this about some people who I greatly respect but they are wrong. For example, research on elite sprinters indicates that the best ones spend less time on the ground. There is an abundance of advice on how to improve your stride rate. In 2000 in The  Journal of Applied Physiology, Peter Weyand and his team found that strides were  1.69 times longer at 11.1 m/sec versus 6.2 m/sec, and stride rate or frequency was  1.16 times faster! A video at the New York City Marathon showed that the top 150 runners had the same cadence, taking 184 to 188 steps a minute. One could also, determine the sprinter’ max stride length and adjust the distance between the hurdles downward as strength etc improves increase the distance between the hurdles. Medicine and Science in Sports and Exercise 43: 1055‐1062, 2011. This usually results in a slower pace. The single support phase corresponds to a period of glide, while the double support phase corresponds to the onset and preparation of propulsion (Marino, 1977). Additionally, stride rate decreased (P<0.0001) as distance increased (2.96, 2.81, 2.45, 2.23 strides/sec, respectively). To calculate your stride rate, use a stopwatch, watch with a second hand or other device to count the number of footfalls on your right foot for one minute. Stride length. So, your speed is ultimately determines by how quickly your stride rate, or frequency, is, and how much ground you cover in each one of those strides. Compared to changing your stride length, increasing your stride rate is relatively straight-forward. Stride rate increased 3.2%, speed increased by about 40%, and stride length increased by 35%. 74-Mann R. The Biomechanical Analysis of Sprinters. Your running stride has two components: stride rate, which is the number of steps taken per minute, and stride length, which is the distance of each step. The difference that makes the difference for the elite is their stride length. Increasing your stride rate by 10%, say, from 160 to 176 strides per minute is much easier than lengthening your stride by 10%. He earned a doctorate in Sports Management from the United States Sports Academy, a master's degree in kinesiology from California State University, Fullerton, and a bachelor's degree in exercise science from Central College. Stride frequency relates to the time factor, while stride length relates to the distance factor. Though, I have done very little experimenting. For anything less, you want a solid combination of both elements. Both techniques are proven effective at increasing running speed. On the other side, lengthening your running stride means forcing a longer stride than your usual one. Of the 11  athletes total, 9 of them ran under 10.00s in at least one of their races. Like most areas of sports performance, stride rate and stride length function on a bell curve. Runner’s stride rates vary from one another. Keep in mind that this study compared fast runners to slower ones. Extracting Gait Velocity and Stride Length from Surrounding Radio Signals Chen-Yu Hsu 1, Yuchen Liu2, Zachary Kabelac , Rumen Hristov , Dina Katabi1, Christine Liu3 1MIT CSAIL, Cambridge, MA 2Hong Kong University of Science and Technology, Hong Kong 3Boston University School of Medicine, Boston, MA {cyhsu,zek,rhristov,dk}@mit.edu, yliubs@ust.hk, christine.liu@bmc.org according to this article a good rate would be around the 200 mark which seems pretty big to me and that stays the same if going fast or slow its the stride length that determines speed rather then stride rate. 48-Clark, M, NASM Essentials of Personal Fitness Training, Baltimore, MD, Lippincott Williams & Wilkins: 2008. This could be a conundrum to many. When doing strides the most important thing is to focus on is your form. I have theoretical hurdle placements for a 1.6 m stride length to a 2.3 stride length. Stride rate and running cadence has a strong correlation to your foot strike and running gait. Research has concluded that most elite runners have the same running cadence per minute. The best solution for running faster is by combining both methods. The researchers supported this notion as well. Let's start with stride length first. Improving running speed and time are the most neglected parts of running training. Your foot should be landing directly under your body, not out in front. Age has an influence on both walking speed and stride length. 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. I have a stride rate of about 165 steps per minute this goes up or down buy a few if i speed up or slow down. Lengthening your stride can cause you to overstride. 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. And stride rate is generally less of a concern when coaching unless the athlete is getting in their own head and thinking too much or just flat out tired from training. It will make your runs more efficient. In general you can run faster by either improving your running cadence per minute or by lengthening your stride. But, and here’s the catch, stride rate can only improve so much. Researchers came to the conclusion that some of the runners relied upon greater stride length compensation while other relied on stride rate. There are different viewpoints regarding the importance of stride length and stride frequency when acquiring maximum speed, as well as maintaining it. This forces your body to slow down and generates added pressure and tension to your feet and knees, thus it increases the risk of injury and knee problems. 17 of each runner’s races were assessed and the mean race time was 10.12 seconds! They compared men and women. Stride rate describes how fast strides are taken and the units are strides per time. 2005. The most efficient stride length is the innate one – the one you feel most at ease with. Both stride length and stride frequency are the biggest factors that play a role in your sprinting speed. First, the force-velocity or “power” curve applies in this discussion of length vs. rate mechanics. Stride frequency relates to the time factor, while stride length relates to the distance factor. It is approximately 2.1 to 2.5 times leg length. Often times when athletes or coaches will falsely assume that you need to initiate extremely fast and short lived steps at the beginning of the sprint in order to run faster. But don’t worry, there are some tweaks you can do in order to decrease the effects of overstriding. However, they are usually within 20 to 30 steps each minute. I discuss Usain Bolt, Tyson Gay, and some of the best sprinters of all time. A lot of pro runners elicit increased stride rates between 180 to 200 steps every minute. And at the same time, you should adopt a stride length that is comfortable to you. Speed is commonly said to be the product of stride rate x stride length. In which case they have to be able to effectively oppose higher ground forces, momentum, and gravity within milliseconds to propel themselves forward again and this function repeats itself with each landing and phase cycle of sprinting. 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. We assessed and counted several participants and James was in the low 20s at a height of only 5’9”! Experts like to break each  element down into smaller phases, but I really do not think there is a need to, and a  general definition is adequate. STRIDE RATE. 46-Clark, M, Integrated Flexibility Training. Running Stride Rate A good running stride rate is 85 to 95 single-leg strides per minute— 90 is ideal. Meaning, too little or too much of either variable will be inefficient. Overstriding is one of the most common lower body errors runners make. James and Merritt struggled and they didn’t even go under 12.5 seconds whereas van Niekerk had enough in the tank to hold on for the worl… Stride Rate Vs. Your stride rate (how many steps you take per minute) is the best indicator of how suitable your stride length is for you. So to go faster, we want to eventually increase our stride length as well. Thousand Oaks, CA: 2001. International Journal of Sports Medicine and Coaching 6: 479‐494, 2011. In this post, I break down sprinting into Step Frequency and Stride Length in the context of the 100m, 200m, and 400m sprints. This isn’t necessarily an all out sprint but rather a controlled fast pace. Stride length is the distance at which your legs strikes the ground while running. Strides are usually around 100 meters in length. Both lead to the exact same result. Stride length varies from person to person, but an ideal running stride should be relatively short in length.
