I learn a paper this week that basically acquired me pondering. When we analyse a runner’s gait we often achieve this with a view to injury. We’re asking ourselves if the person’s gait could place extra stress on delicate tissue and whether or not we will change it. I also usually surprise although what influence such adjustments could have on efficiency. This new examine went some method to answering that query and exploring the interaction between gait, loading and effectivity…

Step Frequency Training Improves Running Economy in Well-Trained Female RunnersQuinn et al. (2019)

Running Economy is a measurement of effectivity in runners. Runners with good economic system use much less oxygen than runners with poor economic system on the similar regular state velocity (Barnes and Kilding 2015 – an ideal open entry paper if you happen to’d like to seek out out extra).

There are some intriguing findings right here that link to analysis on running injury in addition to different research on economic system. For instance Quinn et al. (2019) report that step charge elevated by roughly 7.5% which is also how a lot Willy et al. (2015) aimed to extend step charge by of their examine which noticed reductions in influence pressure, hip adduction and knee load.

A current examine (Pizzuto et al. 2019) discovered that knee flexion/ extension and hip adduction throughout stance had been related to running economic system, with hip adduction explaining as a lot as 43% of the variance in economic system. In a nutshell elevated knee flexion or hip adduction throughout stance seem prone to have a adverse impact on economic system. They’re also thought to extend load on a number of tissues, particularly the patellofemoral joint (Lenhart et al. 2014, Neal et al. 2016).

Increasing step charge by 10% has been discovered to scale back peak knee flexion and hip adduction (Schubert et al. 2014) and scale back patellofemoral load and peak muscle forces for the calf, quads and glutes (Lenhart et al. 2014). An enhance in step charge has also been reported to scale back peak achilles load, (Lyght et al. 2016) tibial load (Edwards et al. 2009) and plantar fascial load (Wellenkotter et al. 2014). Luedke et al. (2016) discovered these with a low step charge (164 or much less) had been extra prone to develop shin ache that these with a better step charge (174 or above).

It would seem that making small will increase in step charge of roughly 7.5% to 10% could have constructive results for each economic system and tissue loading. There is proof that this will scale back ache (Dos Santos et al. 2019) however it’s honest to say research utilising step charge will increase in these with ache/ pathology stay restricted. In addition reducing hip adduction in feminine runners with extreme hip adduction throughout gait has been discovered to enhance signs in patellofemoral ache (Noehren et al. 2011, Willy et al. 2012). Based on Pizzuto et al’s outcomes this will help economic system too.


As ever we should concentrate on the restrictions of the analysis, for instance in Quinn et al’s examine are outcomes influenced by the training impact of sustaining a major enhance in step charge for 15 minutes? An 11% lower in oxygen consumption does appear a big change however then smiling when you run has been discovered to enhance economic system by almost 3% (Brick et al. 2018)! It’s necessary to recognise that growing cadence is way from a treatment all and ought to be based mostly on a person’s want and targets. Step charge is influenced by velocity and height and tends to be greater in additional skilled athletes (Luedke et al. 2018). There’s no single method to it (equivalent to aiming for a cadence of 180) that may go well with everybody.

The members in Quinn et al’s examine all had low step charges, outlined as lower than 176 steps per minute (spm). Those with a decrease step charge usually tend to profit from a rise than these already at excessive most well-liked step charges. This ties in with de Ruiter et al. (2014) whose graphic we’ve tailored beneath. For these with low step charges (like our running determine within the picture) growing could take them nearer to their optimum, nonetheless each coronary heart charge and running value seem to extend above this.

Adapted from de Ruiter et al. (2014).

If step charge is already excessive or we enhance it an excessive amount of it could actually have a adverse impact on running economic system and result in a excessive variety of loading cycles. This is the commerce off, growing steps per minute could imply decrease peak hundreds however it does imply extra loading cycles and this must be thought of.In clinic we regularly see a ‘shuffling gait’ on account of an extreme enhance in step charge as demonstrated by the runner beneath. Note how toe off of the left leg is going on nearly instantly earlier than foot strike of the proper, which means minimal flight time and decreased stride size.

Thinking about your running method could be detrimental for running economic system (Schücker and Parrington 2018) and so any adjustments we make must outweigh the consequences of elevated effort to make these adjustments, particularly within the quick time period. Innovative new analysis from Whittier et al. (2019) means that whereas gait adjustments could enhance cognitive demand within the quick time period this reduces over time with observe. It could also be that acutely economic system is worse on account of the trouble of creating a change however this improves as we study the method, nonetheless extra proof is required to reveal this and to see what have an effect on gait adjustments have on efficiency.


A little bit of an extended one at present however hopefully some food for thought which will show helpful when analysing and altering running gait in clinic.
