In our final weblog, what’s essentially the most environment friendly approach to run? we touched on how rising step price might assist effectivity for some runners. At present we’re going to discover how this may increasingly additionally lower load on a number of tissues and, in some circumstances, instantly scale back ache when operating! Now, earlier than you all fireplace up your metronomes we’re additionally going to cowl 4 key factors to think about when rising step price.
Observe: Within the research they often use the time period ‘step price‘ to explain the overall variety of operating steps per minute. Runners often name it ‘cadence‘ so I’ll use the phrases interchangeably as they imply the identical factor!
Now, you understand me, I like a graphic! So let’s begin with one to summarise a number of the potential advantages of accelerating step price by as little as 5 to 10%.
To extend step price we often start by assessing it in a runner whereas operating at a set pace. You should use a wearable system or GPS watch or just depend the footfalls for one foot throughout a minute and multiply that quantity by 2 to get the step price.
Subsequent, we set a metronome 5 to 10% increased than this quantity, so if the runner was at 160 steps per min (spm), we regularly begin by rising 5% which might be 168spm. Then we ask the runner to run to the beat of the metronome. There are Apps which may also help akin to MetroTimer or RunCadence.
Research have examined the consequences of accelerating cadence by 10% and have proven some actually encouraging outcomes. For instance, Bramah et al. (2019) reported decreases in patellofemoral ache and will increase in longest distance run pain-free from a single gait retraining session!
Some runners report prompt advantages from gait adjustments. Esculier et al. (2023) examined the consequences on gait retraining in runners with patellofemoral ache, they included step price will increase and different cues and located that 47% had a right away discount in signs.
However, you understand what additionally they discovered?… some individuals’s ache elevated!
Clearly, rising step price is not a cure-all, and there’s nobody dimension matches all method that works. Numerous issues affect a runner’s cadence and it’s extra of a continuum than a magic quantity all of us intention for:
Growing cadence definitely has the potential to assist runners however we must always pay attention to the restrictions of this method, particularly after we think about the proof.
A current systematic evaluation (Anderson et al. 2022) recognized 37 research analyzing the consequences of fixing step price. Solely 2 of those had been associated to ache or harm! The overwhelming majority focussed on the biomechanical results in wholesome runners.
Most analysis inside this evaluation assessed quick results of accelerating or reducing step price. Some research have medium-term observe up information (e.g. 12 weeks) however the longer-term results are largely unknown.
4 key factors to think about when rising step price:
- Lowered load per step could also be offset by the elevated variety of operating steps per minute.
- Response will range relying on preliminary most popular step price. These with a excessive beginning step price (e.g. >175) are much less more likely to profit.
- Particular person ache response will range and a few report elevated ache!
- Any gait change must be based mostly on particular person evaluation not a one dimension matches all method.

These with a low beginning step price and gait findings which can be doubtless to enhance from a rise (akin to over-striding or elevated hip adduction) usually tend to profit. Strive a small change (e.g. improve 5-8%) and see how they reply when it comes to gait and signs. In the event that they don’t have ache throughout the gait evaluation itself then counsel they struggle it if their signs come on mid-run to check response.
