Energy absorption of impacts during running at various stride lengths. Lorenz DS, Pontillo M. Is there evidence to support a forefoot strike pattern in barefoot runners? Stride length and step length are two important measurements in gait analysis. Running Drills That Improve Stride Length. The caveat is that a player can be too low, which will add too much length to the stride… (Note, bikers use the term for rotations; thus, 90 is One Step Ahead: Optimizing Worker Performance, Comfort, and Safety through Footwear. 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… Cavanagh PR, Lafortune MA. 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). That being said, the distance of the race also matters. Lower extremity stiffness: implications for performance and injury. Every runner is a bit different, but for most people, smaller strides are beneficial for alignment. The converse can be said for decreasing pace (reduced stride length and cadence). Decreasing stride length during running has been associated with several biomechanical changes that may underlie reduced injury rates. Surrogate measures of bone strain, such as external ground reaction force and tibial shock, display positive relationships with stride length. Lift your right foot and swing it forward past your left foot, and place it on the ground. Start with your two feet together and start walking. Ridge ST, Johnson AW, Mitchell UH, et al. Tall people take longer strides when running. Orthopedics 2011;34(7):e320-e323. Stride length and step length are two important measurements in gait analysis. Increasing your stride rate by 10%, say, from 160 to 176 strides per minute is much easier than lengthening your stride by 10%. Thompson MA, Gutmann A, Seegmiller J, McGowan CP. J Biomech 2014;47(11):2745-2750. Add Cadence Improving Workouts. Ozburn MS, Nichols JW. Forefoot running improves pain and disability associated with chronic exertional compartment syndrome. Gait analysis can help doctors diagnose injury and other underlying conditions. Reducing your stride length so your foot lands under you reduces that braking force." Med Sci Sports Exerc 2004;36(5):845-849. Reducing your stride length so your foot lands under you reduces that braking force." When you hit the first mark, start counting your steps, stopping your count when you hit the second mark. 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. Effects of stride length and running mileage on a probabilistic stress fracture model. Larger stride angles have been shown to lower VO2 at a given velocity, by decreasing stride length or increasing swing time, which makes for more efficient recycling of oxygen at a given pace. CP J Biomech 1980;13(5):397-406. Do You Have a Good Stride? Incidence and determinants of lower extremity running injuries in long distance runners: a systematic review. Ok, explaining stride length is easy. Med Sci Sports Exerc 1998;30(1):128-135. J Biomech 2008;41(6):1160-1165. 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. If you can rattle off the answer without even checking your watch, you’re not alone. While skating naturally requires a propulsive action from the stride leg, skating depth (and therefore stride length) is largely influenced by the position of the stance leg. The speed will happen after you decrease your stride length and increase your cadence. Your stride length is the length of each of your steps. Lenhart et al and Willson el al, respectively, examined the effect of decreased stride length during running on patellofemoral joint forces and joint stresses.35,39 Both groups found that decreasing stride length greatly reduced patellofemoral loading. Draw another line from that front foot straight up. While there is evidence to suggest that reducing stride length leads to biomechanical changes associated with reduced risk of running-related injury, there are several confounding factors that should be considered. A review. Evidence suggests that decreasing stride length results in biomechanical changes, including reduced GRFs and joint moments, that can contribute to reduced injury risk. Studies in the early 1970s found that average stride length for sprinters ranged from 1.14 to 1.35 times the athlete’s height. Last medically reviewed on September 19, 2018, Do you know how many steps you average each day? A lower cadence typically indicates a longer stride, while a higher cadence indicates a shorter stride. Exercises to Improve Stride Frequency. Sometimes the terms “step length” and “stride length” are used interchangeably, but it’s likely the number they actually want is step length. Although decreasing stride length may reduce acute loading, increas-ing stride frequency means a greater total number of ground contacts. Several studies have shown significant differences between barefoot running and running in minimalist shoes. To fix this, try cueing the player to bend their knees a little more and to stay low throughout the full stride. Bonacci J, Saunders PU, Hicks A, et al. Taunton JE, Ryan MB, Clement DB, et al. "Finding your perfect stride length is a matter of finding the stride that reduces your braking force," Suydam says. How many steps/strides will it take me to walk a mile? • Step length: The distance traveled in one step, which, on average, is about 28 inches in the healthy adult. Morin J, Samozino P, Zameziati K, Belli A. 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). Simply put, to increase stride length, one must increase power output of the lower body. Hobara H, Sato T, Sakaguchi M, et al. One gait alteration that has been proposed to reduce running- related injury risk is reducing stride length. Your stride length is the length of each of your steps. Given that the knee is the most frequent site of running-related musculoskeletal injury, several studies have examined the effect of reduction in stride length on clinical conditions surrounding the knee. They also help to improve core stability which contributes to the transfer power through the ground and into forward movement. Mark your starting point and walk until you’ve counted 50 steps. One study identified that athletes ran, on average, 23% slower uphill and 13.8% faster downhill compared with their speed on flats, with speed changes primarily caused by decreasing stride length on the uphills (Townshend et al. 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. J Sports Sci 2014;4:1-8. It is possible that lower loads applied more frequently may also increase injury risk. All rights reserved. Kinetic consequences of constraining running behavior. Step frequency and lower extremity loading during running. What is the average step length and stride length? Don’t try to run faster. 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. Hafer J, Brown A, deMille P, et al. 3-7 These parameters are interdependent and their optimal ratio allows for a maximum running speed. J Sports Med Phys Fitness 2003;43(3):319-326.
