# stride frequency vs stride length

Maybe a little bit, but for the most part, your legs are still cycling through at a fairly decent rate. the stride frequency, which forces changes in stride length in order to fulfill the velocity constraint. Speed is a function of the frequency and the length of the stride.3-7 These parameters are interdependent and their optimal ratio allows for a maximum running speed.8The increase in speed can be achieved by increasing the length or frequency of the stride. Thereâs plenty of anecdotal evidence too: elite runners tend to have a fairly high stride frequency, 180 steps per minute or more, even at slow paces, while recreational runners tend to have quite a low stride frequency, sometimes as low as 150 or 160 steps per minute. The difference that makes the difference for the elite is their stride length. Stride Length: SL: m: Distance between consecutive â¦ But, which has the greater impact on overall 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.

Stride frequency, being easy to measure, is well suited to analyzing and defining gait in a practical context. One simple strategy for running stride frequency or length has been commonly advocated. Stride too long While others will say just the opposite and work on the stride length. It simply means that to see a change in speed you’ve either got to increase the ground you cover (stride length) or increase your turnover (stride frequency) or … A cinematographic analysis of overground and treadmill running by males and females. Most training out there is geared towards training for stride frequency. Mr Bolt's average step frequency (cadence) was 4.28 steps per second. In this case, you took 8 strides in 20 feet, so your stride length would be 2.5 feet (30 inches). Posted by. Stride length is the distance covered during a stride and is typically represented as m/stride. Effects of Running Velocity on Running Kinetics and Kinematics, Selected Determinants of Acceleration in the 100m Sprint, Stride-to-stride variability while backward counting among healthy young adults. However, 1952;14(6):431-6. When a subject intends to walk at a given speed, that speed is attained with a specific stride frequency and length [11,26]. Distance in feet/number of strides = stride length. In short, speed = stride length x stride frequency. An analysis of Wayde van Niekerk's stride â¦ What about stride length? Based on this article in Pose Tech when Usain Bolt ran his world record time of 9.58 seconds he made 41 steps with an average stride length of 2.44 meters per step. While others will say just the opposite and work on the stride length. â Stride Length vs Stride Frequency in the 400 Metres.
