The converse can be said for decreasing pace (reduced stride length and cadence). 2010). The effect of stride length on the dynamics of barefoot and shod running. Don’t try to run faster. To fix this, try cueing the player to bend their knees a little more and to stay low throughout the full stride. A runner's average stride length will depend on her height. A prospective study. Kinetic variables in subjects with previous lower extremity stress fracture. Running stride tends to change as people age, with older runners naturally decreasing their stride length and increasing their stride turnover [source: Bus]. But is it real? While there is fairly extensive biomechanical research that supports the argument for runners adopting a shorter stride length, there is limited clinical research showing that gait retraining to attain shorter stride length is a successful modality to treat or prevent running-induced musculoskeletal injuries. Kinetic consequences of constraining running behavior. Decreasing stride length during running has been shown to result in several biomechanical changes that are associated with reduced loading of biological tissues and, by extension, also may be associated with reduced injury risk. Shock attenuation and stride frequency during running. There might be a difference between your left step length and your right step length. Your stride length is the length of each of your steps. Diebal AR, Gregory R, Alitz C, Gerber JP. First, decreasing stride length—particularly if it is achieved by switching from shod to barefoot running—may result in individuals contacting the ground initially with the forefoot rather than the rearfoot. Is there any evidence that we enhance our running efficiency by subtly increasing or decreasing stride length? How Many Calories Do You Burn While Walking? Edwards et al used a finite element model to examine the effect of a reduction in stride-length on the probability of tibial stress fractures.13 The authors found that reducing stride length by 10% decreased the probability of stress fracture by up to 6%.13 Lastly, Rowlands et al examined the effect of stride-length manipulation on strength retention and muscle soreness with repeated bouts of downhill running.41 They found reducing stride length during downhill running decreased exercise-induced muscle damage and provided protection against muscle soreness.41, While not examining the effect of stride length directly, much of the research looking at the effect of barefoot running and minimalist shoes indirectly evaluates stride length, as barefoot/minimalist runners tend to adopt a reduced stride length. • Stride: The events that take place between successive heel contacts of the same foot. Calculating the Distance of 10 Steps Pick a starting place and mark it with an item. Start with your two feet together and start walking. Br J Sports Med 2013;47(6):387-392. Hafer J, Brown A, deMille P, et al. Thanks for this great review article. Running is one of the most popular fitness activities, yet it is associated with a high incidence of lower extremity musculoskeletal injury. Short distances call for long strides. Cavanagh PR, Lafortune MA. Hum Movement Sci 2000;19(2):139-151. If it took you 16 steps to cover 20 feet, divide the number of steps (16) by 2 to get the number of strides. It will happen. Research has shown that decreasing stride length decreases the impact peak15 and active peak of the vertical GRF,16-20 and has found that reducing stride length results in a decreased vertical loading rate of the GRF.15. A Real-World Approach to Diabetic Footcare, Orthotic management of CMT: Dynamic solutions for active lifestyles, Orthotic Management of CMT: Dynamic Solutions for Active Lifestyles. In terms of tibial stress fracture, Edwards et al reported that strain magnitude plays a more important role than the total number of loading cycles in stress fracture development.13 Additionally, Willson et al found that patellofemoral joint stress was lower with decreased stride length and, despite more strides per mile, patellofemoral joint stress per mile was also reduced.35 However, other musculoskeletal injuries may be more sensitive to the number of loading cycles. BOCO
Decreasing Stride Length May Reduce Injuries A video at the New York City Marathon showed that the top 150 runners had the same cadence, taking 92 to 94 steps a minute. Jog slowly or walk back to the top, then repeat. Lenhart RL, Thelen DG, Wille CM, et al. Normal adult stride length averages approximately 1.39 m, with the mean stride length of men (1.48 m) being slightly longer than that of women (1.32 m). Increasing stride length relative to velocity appears more feasible than decreasing stride length (increasing cadence) possibly because the latter is influenced by the pendular mechanics of the leg , which are essentially constant over the lifespan. Treatment of distal iliotibial band syndrome in a long distance runner with gait re-training emphasizing step rate manipulation. Specifically, decreasing stride length has been shown to reduce GRFs, joint moments, impact accelerations, and leg stiffness, factors that have been associated with a greater risk of running-related injury.1,12,13 GRF magnitude provides an estimate of the forces that are transmitted to the mus… Am J Sports Med 1993;21(5):705-710. One question that is always asked is whether an athlete should focus on increasing stride frequency or stride length. I found plenty of good reasons to persist here. © 2005-2021 Healthline Media a Red Ventures Company. Med Sci Sports Exerc 2004;36(5):S58. In a 2007 study, researchers studied the optimal stride frequency and running economy (efficiency) in 16 trained runners during an intense 1-hour run(1). The speed will happen after you decrease your stride length and increase your cadence. Acute differences in foot strike and spatiotemporal variables for shod, barefoot or minimalist male runners. Gait analysis is a study of how a person walks and runs. Ferber R, McClay-Davis I, Hamill J, et al. What they found was that as the run progressed and fatigue set in, the stride length tended to become shorter. A review. One gait alteration that has been proposed to reduce running- related injury risk is reducing stride length. Does increased loading during running lead to tibial stress fractures? Hum Movement Sci 1995;14(1):45-60. It’s when the exercise feels impossible to finish. Over-striding means that you will generate less power during ground contact. Simply put, to increase stride length, one must increase power output of the lower body. Impact forces during heel-toe running. This article tells you whether you can lose weight by walking 1…. Melissa Thompon, PhD, is an assistant professor of exercise science at Fort Lewis College in Durango, CO. Kristine Hoffman, DPM, is a podiatrist in private practice with Boulder Valley Foot and Ankle Clinic in Colorado. Foot bone marrow edema after a 10-wk transition to minimalist running shoes. Calf Hops. Management of pain beneath the heel and Achilles tendinitis with visco-elastic heel inserts. Br J Sports Med 2008;42(9):746-749. Stride length is the distance covered when you take two steps, one with each foot. Gait analysis can help doctors diagnose injury and other underlying conditions. Lift your right foot and swing it forward past your left foot, and place it on the ground. J Sports Sci 2001;19(5):333-340. Jones B, Bovee M, Harris JM 3rd, Cowan DN. Internal forces of chronic running injury sites. Divide the number of feet in your measured distance by the number of steps you took from the first mark to the second. Be sure to maintain a consistent pace while you’re counting, as your cadence will shift as you increase and decrease pace, along with your stride length. Kinematic and kinetic parameters associated with running in different shoes. Increasing stride length relative to velocity appears more feasible than decreasing stride length (increasing cadence) possibly because the latter is influenced by the pendular mechanics of the leg , which are essentially constant over the lifespan. When running speed is kept constant, stride length and stride frequency are inversely related. I have theoretical hurdle placements for a 1.6 m stride length to a 2.3 stride length. Rowlands AV, Eston RG, Tilzey C. Effect of stride length manipulation on symptoms of exercise-induced muscle damage and the repeated bout effect. J Sports Sci 2014;4:1-8. Pubic ramus and adductor insertion stress fractures in female basic trainees. Freeze the frame when your front foot hits the ground. They also help to improve core stability which contributes to the transfer power through the ground and into forward movement. Brit J Sports Med 1994;28(4):256-260. Effects of altered stride frequency and contact time on leg-spring behavior in human running. Additionally, forefoot ground contact, which is associated with decreased stride length and barefoot/minimalist running, has also been associated with higher Achilles tendon strain34 and increased risk of Achilles tendinopathy.46,47, Evaluating the literature on barefoot and minimalist shoe running can be difficult, as running in minimalist shoes is often thought to mimic barefoot running, but has in fact been found to have biomechanical characteristics more similar to shod running. Start with your two feet together and start walking. Giuliani J, Masini B, Alitz C, Owens B. Barefoot-simulating footwear associated with metatarsal stress injury in 2 runners. Br J Sports Med 2013;48(5):349-355. Brit J Sports Med 2002;36(2):95-101. It is possible that lower loads applied more frequently may also increase injury risk. Br J Sports Med 2009;43(4):288-292. Joint moments represent the net effect of muscles and ligament acting across the joint, and are commonly used to assess joint loading during running. About Stride Length and Aging and A Routine for Improvement Alan Rider 31 Aug 2015 Preface As runners age, their speed decreases primarily due to a decrease in stride length. Distance in feet/number of strides = stride length. Each of the drills below develops strength and power in the legs. When running at moderate speeds the vertical component of the GRF has peak values approximately three times body weight.14 During running the vertical GRF often has two peaks, the impact peak that occurs at initial ground contact and the active peak that represents the forces at midstance. J Biomech 2003;36(11):1617-1624. The shorter stride lengths were recorded on cinder tracks while the longer strides were recorded on synthetic surfaces. Therefore, stride frequency must be increased to maintain a given running velocity when stride length is reduced. Bonacci et al examined joint kinematic and kinetic variables in runners in barefoot and three shod conditions (minimalist shoe, racing flat, and regular athletic shoe).48 Their results showed significant differences between barefoot and shod conditions for kinematic and kinetic variables at the knee and ankle, but no significant differences between the three shod conditions.48 Further, McCallion et al compared several spatiotemporal variable of athletes running barefoot, in minimalist shoes, and in conventional running shoes.49 They found stride duration, flight time, and contact time were greater in conventional running shoes and minimalist shoes compared with barefoot running.49. Your email address will not be published. Downhill sprint is ideal for improving your technique and increase your leg turnover. To determine the number of steps it will take you to walk a mile, divide 5,280 by your step length. Evidence suggests that decreasing stride length results in biomechanical changes, including reduced GRFs and joint moments, that can contribute to reduced injury risk. Hobara H, Sato T, Sakaguchi M, et al. Using the tape measure and the chalk (outside) or the masking tape (inside), measure and mark off a specific distance, such as 20 feet. Effects of step length on patellofemoral joint stress in female runners with and without patellofemoral pain. These numbers can also be useful for a doctor or physical therapist to evaluate your progress, and thus the effectiveness of treatment prescribed for the condition causing gait irregularities. Stress fracture of the pubic ramus in female recruits. Thanks in part…. 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. Med Sci Sports Exerc 2004;36(5):845-849. Normal adult stride length averages approximately 1.39 m, with the mean stride length of men (1.48 m) being slightly longer than that of women (1.32 m). While this sounds plausible, the science to date says no. Reducing your stride length so your foot lands under you reduces that braking force." With endurance athletes wanting to develop both speed and efficiency, I find that the most important cadence related factors are: 1) Limiting how far the cadence decreases when running at easy/steady paces, thus reducing over-striding. It can also be used to evaluate treatments for injuries and conditions. It also puts a lot of strain on … Stride frequency is determined by ground contact time and leg recovery, or the ability to move from one stride to the next in … Disclosure: The authors report that there are no conflicts of interest associated with this manuscript. If you get a new pedometer or fitness tracker — such as a Fitbit, Garmin, Xiaomi, Misfit, or Polar — you may need to enter your step length during the initial set up. Draw another line from that front foot straight up. Reducing your stride length so your foot lands under you reduces that braking force." 8 The increase in speed can be achieved by increasing the length or frequency of the stride. It also puts a lot of strain on … However, top sprinters can increase their stride frequencies during peak sprinting without decreasing stride length if they apply peak vertical forces. Milner C, Ferber R, Pollard C, Hamill J, Davis I. Biomechanical factors associated with tibial stress fracture in female runners. Pohl M, Hamill J, Davis I. Biomechanical and anatomic factors associated with a history of plantar fasciitis in female runners. J Bone Joint Surg Br 1996;78(3):383-386. DPM
Gill HS, O’Connor JJ. Speed in running is a function of two key elements known as stride length and stride frequency. Further research, including long-term prospective studies aimed at determining the effectiveness of decreasing stride length for successful treatment for specific musculoskeletal conditions, is needed. Sometimes the terms “step length” and “stride length” are used interchangeably, but it’s likely the number they actually want is step length. The effect of varied stride rate upon shank deceleration in running. Though, I have done very little experimenting. Azevedo LB, Lambert MI, Vaughan CL, et al. Importantly, it can also help you lose weight and belly fat. Our website services, content, and products are for informational purposes only. Stride length and step length can be important numbers for a doctor to diagnose a problem with your gait or a condition that could be causing a problem with your gait. Add Cadence Improving Workouts. (Note, bikers use the term for rotations; thus, 90 is Stride length and step length are two important measurements in gait analysis. Overuse injuries are dependent on loading magnitude, type of load, and the number of loading cycles, as well as the health and condition of the relevant biological tissue.3 When running, the body’s mass is repeatedly decelerated, resulting in forces that travel through the musculoskeletal system. Increasing running step rate reduces patellofemoral joint forces. Now both feet are on the ground with the right foot ahead of the left one. Thus, it was suggested that decreasing stride length when running might be an effective means to change biomechanical factors that can contribute to patellofemoral pain.39 Additionally, Allen et al examined the effect of gait retraining with step rate manipulation as a treatment for iliotibial band syndrome.40 In this study, the authors found that a 5% increase in step-rate (resulting in decreased stride length) was an effective treatment for a single runner with iliotibial band syndrome when combined with a home exercise program that included stretching and strengthening.40, There is also evidence suggesting that decreasing stride length may help reduce the risk of stress fractures and muscle soreness in runners. New regimen for eccentric calf-muscle training in patients with chronic insertional Achilles tendinopathy: results of a pilot study. The musculoskeletal system can alter the stiffness of this spring system, and research has shown that decreasing stride length reduces leg stiffness.16,18 It appears likely that there is an ideal level of leg stiffness that minimizes injury risk, with increased stiffness associated with bony injuries and decreased stiffness associated with soft tissue injuries.31, Further, barefoot running, which typically results in decreased stride length, has also been associated with reduced GRFs and joint moments.32 Thompson et al had individuals run in barefoot and shod conditions with stride lengths that were both greater and less than their preferred shod stride length. Specifically, decreasing stride length has been shown to reduce GRFs, joint moments, impact accelerations, and leg stiffness, factors that have been associated with a greater risk of running-related injury.1,12,13, GRF magnitude provides an estimate of the forces that are transmitted to the musculoskeletal system during running. If you want to measure your running cadence manually, it’s as simple as counting strides for 30 seconds and multiplying by two. Tam N, Astephen Wilson JL, Noakes TD, Tucker R. Barefoot running: an evaluation of current hypothesis, future research and clinical applications. In this case, you took 8 strides in 20 feet, so your stride length would be 2.5 feet (30 inches). Jonsson P, Alfredson H, Sunding K, et al. Taunton JE, Ryan MB, Clement DB, et al. Hamill J, Derrick TR, Holt KG. Several studies have shown significant differences between barefoot running and running in minimalist shoes. The magnitude of the effects increased when the subjects moved from ±5% to ±10%. (Note, bikers use the term for rotations; thus, 90 is Power Skips. Hill PF, Chatterji S, Chambers D, Keeling JD. J Sports Sci 1985;3(1):41-49. Clin J Sports Med 2009;19(5):372-376. Second, running velocity is the product of stride length and stride frequency. Your email address will not be published. The caveat is that a player can be too low, which will add too much length to the stride… That being said, the distance of the race also matters. While not directly examining the effect of stride length, research examining the effect of barefoot running and minimalist shoes indirectly evaluates stride length, as barefoot/minimalist runners tend to adopt a reduced stride length. And sharp impact transients decreased at higher stride frequencies. Does Walking 1 Hour Every Day Aid Weight Loss? LER Magazine bridges the gap between lower extremity foot orthotics, custom and prefabricated ankle and knee bracing, diabetic custom foot orthotics and diabetic foot wear, shoe manufacturers and lower extremity central fabricators with lower extremity practitioners by providing: © 2009-2021 Copyright Lower Extremity Review Magazine. Then take the answer (8) and divide it into the distance. CPed

Ridge ST, Johnson AW, Mitchell UH, et al. Surrogate measures of bone strain, such as external ground reaction force and tibial shock, display positive relationships with stride length. McNair PJ, Marshall RN. J Biomech 2014;47(11):2745-2750. Draw a line from your belly button straight down. Leg stiffness and stride frequency in human running. • Step: The events that occur between successive heel contacts of opposite feet, for example, between left and right heel contacts. Additionally, studies examining running injury risk in barefoot/minimalist shoe conditions, and the resulting decrease in stride length, are needed to determine if shoe gear changes and the resulting gait changes are a successful means of reducing running-related injury risk, or if they could potentially lead to increased risk of certain injuries due to lack of forefoot cushioning.
