Does Cadence Affect Running Economy? What Research Shows
Cadence does affect running economy, but not in the simple "higher is always better" way it's often marketed. Research going back decades shows that most runners naturally settle into a cadence that's close to their most metabolically efficient one, and that pushing cadence far away from that self-selected rate—in either direction—tends to raise the oxygen cost of running, not lower it.
What is running economy, and how is it measured?
Running economy is the amount of oxygen your body uses to run at a given pace—usually expressed as milliliters of oxygen per kilogram of body weight per kilometer (mL/kg/km). Better economy means you're spending less energy to hold the same speed, which matters more for distance performance than almost any other physiological variable besides VO2 max.
The catch: measuring economy accurately requires a metabolic cart—a mask and gas-analysis system usually found in an exercise physiology lab, not a phone camera. No video-based tool, including form-analysis apps, can tell you your actual oxygen cost. What a phone video can do reasonably well is measure cadence (steps per minute), which is a useful proxy variable to track over time, not a direct read on efficiency.
Do runners naturally settle into an economical cadence?
Yes, largely. A frequently cited line of research, starting with Cavanagh and Williams' 1982 work on stride length and oxygen uptake, found that when runners were asked to run at a range of different stride lengths (and therefore cadences) at a fixed pace, their freely chosen stride rate was close to the one that minimized oxygen cost for most individuals. In other words, without being told anything about cadence, most runners already gravitate toward something near their own optimum.
This self-optimization isn't identical across people. Natural cadence varies with leg length, running speed, muscle-tendon stiffness, and other individual traits—some of which appear to have a genetic component, as discussed in is running cadence genetic. That's a big part of why there's no single "correct" number that fits everyone, despite the popularity of round targets like 180 steps per minute.
What happens when you force a much higher cadence?
Small increases are usually well tolerated. Studies manipulating step rate—most notably Heiderscheit and colleagues' 2011 work in Medicine & Science in Sports & Exercise—found that increasing cadence by around 5–10% above self-selected reduced loading at the knee and shifted impact forces in ways that may lower injury risk for some runners, generally without a large economy penalty at that range.
Push much further, though, and the oxygen cost curve turns against you. Forcing a cadence 15–20% or more above what feels natural typically increases the metabolic cost of running because you're taking smaller, choppier steps and doing more work per stride to maintain speed. This is why cadence changes used for a specific mechanical goal—like reducing shin or knee loading, or managing symptoms discussed in cadence for Achilles tendinopathy—are usually introduced gradually and in a modest range, not jumped to all at once.
Going too low has costs too. A cadence well below your self-selected rate generally means longer strides and more overstriding, which can increase braking forces and vertical oscillation—both of which raise oxygen cost. Runners sometimes end up here after being told to "reach farther" without cadence guidance.
Why does the oxygen-cost curve look U-shaped?
When researchers plot oxygen cost against cadence at a fixed running speed, the resulting shape is typically a U (or a shallow, slightly asymmetric U): oxygen cost is lowest somewhere in the middle and rises as cadence moves toward either extreme. The self-selected cadence for most runners sits at or very near the bottom of that curve.
This matters practically because it means the goal isn't to chase a universal "ideal" cadence number, but to find where your own U-curve bottoms out. It also explains why moderate cadence experiments (a few spm change) often feel neutral or even comfortable, while extreme ones feel labored almost immediately—your body is telling you, quite literally through effort and breathing, that you've moved up the sides of the curve.
| Change from self-selected cadence | Typical effect on oxygen cost | Practical note |
|---|---|---|
| 0% (your natural cadence) | Generally near the lowest point on the curve | Baseline for most runners |
| ±3–5% | Minimal, often not noticeable | Common range for gentle experimentation |
| +8–10% | Small increase, sometimes offset by reduced impact loading | Typical range used in gait-retraining studies |
| +15–20% or more | Measurable increase in oxygen cost | Cadence starts to feel forced, choppy |
| -10% or more (long, slow strides) | Increase in cost from overstriding/braking | Often linked to reaching or heel-first landings |
These are general patterns from the biomechanics literature, not fixed percentages that apply identically to every runner—individual variation is real.
How do you find your own economical cadence?
Start by measuring, not guessing. Count steps for 30 seconds during an easy, steady-state run and double it, or use a running watch's cadence readout, averaged over a few runs at your typical easy pace. That number—not 180, not a number from a training plan—is your practical starting point, since economy is typically best near what you already do naturally.
From there, cadence also shifts with pace: most runners run at a noticeably higher cadence when sprinting than when jogging, so a single target number ignores that relationship. For pace-specific ranges, see cadence targets by pace rather than applying one number across every run.
If you do want to experiment—say, a physio has suggested a modest cadence increase for a loading-related issue—make small changes (5–10%) over several weeks rather than jumping straight to a new number, and monitor how it feels, not just how it measures. Some tools, including StrideIQ, can estimate cadence from a single side-view phone video, which is a reasonable way to spot-check your current rate and track whether a gradual change is sticking—but it's a cadence check, not an economy test, and it won't tell you your oxygen cost.
Watch for secondary signals too. A sudden change in footstrike sound, like a new or worsening slap on landing, can indicate the cadence change is disrupting your normal mechanics rather than improving them—see why does my foot slap when running for what that usually means.
What can cadence analysis NOT tell you about your running economy?
A cadence number, however accurately measured, is not a running economy score. Economy depends on oxygen uptake, which requires a metabolic cart and controlled lab conditions—no phone video, wearable, or app can substitute for that measurement. Video-based tools are also limited for anything beyond cadence: ground contact time, vertical oscillation, and joint angles need high-speed or multi-camera capture to be measured with confidence, and a single side-view phone video only estimates them.
The research on cadence and economy is also genuinely mixed at the edges—individual variation is large, and what improves one runner's economy can worsen another's, especially outside the 5–10% adjustment range. Cadence changes made to address pain or injury symptoms should be treated as general guidance, not a treatment plan; if you're adjusting cadence because of ongoing pain, a physiotherapist or sports medicine physician can assess your individual mechanics and injury history in ways a video or app cannot. If you want an actual running economy measurement, an exercise physiology lab or a qualified running coach with metabolic testing access is the right resource, not a self-filmed video.
Frequently Asked Questions
Does a higher cadence always improve running economy?
No. Research shows oxygen cost typically follows a U-shaped curve around a runner's self-selected cadence, so pushing cadence well above natural—rather than toward it—usually increases oxygen cost instead of lowering it.
What is a normal cadence for running economy?
There isn't one fixed number; economy is typically best near each runner's own natural cadence, which varies with leg length, speed, and individual biomechanics rather than matching a universal target like 180 steps per minute.
How much can cadence change before it hurts running economy?
Studies manipulating step rate suggest changes of roughly 5–10% from self-selected cadence are usually well tolerated, while deviations of 15–20% or more tend to raise oxygen cost noticeably.
Can a phone video measure my running economy?
No. Running economy requires oxygen-uptake measurement from a metabolic cart in a lab setting. A phone video can estimate cadence reasonably well but cannot measure oxygen cost, ground contact time, or vertical oscillation with lab-grade accuracy.
Should I change my cadence to run more efficiently?
Only cautiously and gradually. Small, incremental adjustments (5–10%) toward or slightly above your natural cadence are generally low-risk, but large forced changes can increase effort; if you have pain or injury history, involve a physiotherapist or coach.
