"By using OnTracx I discovered that there’s a real difference in load depending on the terrain I run on. Now, I use OnTracx to map my load during every running session".
“OnTracx gives you more confidence that you can run to improve your health without jeopardizing it.”
“I was surprised by how much load my body has to endure during every run, and how much it changes between runs. I now use OnTracx to gradually increase the load week by week, instead of only focusing on running speed and distance.”
”As a data freak, OnTracx is perfect for me. I love to learn more about my body and how it reacts to my training.”
”As a currently injured runner, OnTracx is my ideal running coach. It helps me to understand what my body can handle, so I can keep enjoying my weekly runs. Love it”.
“Can’t run without it.”
“As a runner who suffered from injuries before, OnTracx provides me with relevant data and insights in order to rehabilitate in an efficient way.”
OnTracx allows me to gradually increase the load my patients experience, in a valid and evidence-based manner. By monitoring mechanical load in combination with pain and comfort experienced by the patient, it allows me to provide better follow-up during the return-to-run process in a very time efficient manner.
What I really like is the visualization of mechanical load in such a way that it is easy to understand. Both for me as a professional as for my athletes. I use OnTracx to educate my athletes when it comes down to mechanical loading, and how it relates to the occurrence of overuse injuries.
Running with lower loads offers long-term benefits in terms of joint health. OnTracx allows you to quantify and subsequently manage that load, and can as such be considered an alternative for knee surgery in patients with mild to moderate knee osteoarthritis.
Runners, clinicians and the running industry have needed something like this since forever.

The mechanical load is the load that your muscles and bones (of the lower extremities) have to endure during running.
Mechanical load is very different from the so-called ‘physiological’ load, which represents e.g. your heart rate, your breathing and how much energy your body requires during physical activity.
When the mechanical load becomes too much for your body to handle, overuse injuries, such as stress fractures, can occur. Although it has been possible to measure physiological load already for a long time (via heart rate belts, running watches, etc.), OnTracx is the first to quantify mechanical load in a valid and reliable way.
Because more than 70% of all running injuries are caused by too much mechanical load.
Recent scientific evidence shows that many overuse injuries in running occur when the mechanical load a runner experiences is too high for what the body can handle. However, this load is influenced by a number of factors such as running style, surface and footwear choice. As a result, changes in one of these factors can be detected when taking a look at the mechanical load profile of a runner.
Studies have shown that the experienced load can be very different between runners, even when running at the same pace. Until now, this load is typically measured on a treadmill in very specialized and expensive lab settings (only covering a short period of time). This makes such analyses very expensive and difficult to translate to a real-world context.
By using the OnTracx sensor and related algorithms, your load can be measured and subsequently managed correctly every time you go for a run, with the ultimate aim of avoiding (another) running injury.
Simply put, these parameters can all have an effect on the mechanical load you experience.
However, these changes are very individual and can thus differ from runner to runner. OnTracx allows you to discover which surface, footwear type and running style have a positive effect (i.e. lower) on mechanical load. In the case of people transitioning during their rehab into a return-to-run phase, the same information can be used to gradually increase the load on their body, while managing the pain and overall comfort levels.
Yes that’s possible, but only unidirectional and dynamic movements.
OnTracx allows you to discover, both as a patient and a healthcare professional, how much mechanical load the muscles and bones of your lower legs endure while performing other (dynamic and unidirectional) movements such as a drop jump, forward jumps, single leg hops, and so on. As a result, OnTracx can be used as an ‘educational tool’ to teach patients what mechanical load is, and to demonstrate how much load a runner/patient endures during running, step by step.
Did you know that the mechanical load of a single step during a running activity is higher compared to most training drills used in a rehabilitation context?
Currently this is for practical reasons.
Bilateral load quantification can offer valuable information in the return-to-run process. However, mechanical load can currently only be measured based on one leg (but we’re working on it). We advise you to attach the sensor, during rehabilitation, at the injured leg.
It is hard to test all devices out there and bluetooth can sometimes become an issue. However, we keep an updated list of the tested devices right here. If your device is not listed, it does not necessarily mean that it will not be compatible, and it might be interesting to reach out before buying OnTracx.
The OnTracx sensor measures the acceleration of the tibia (or shin bone) during running.
Scientific research showed that the peak of this tibial acceleration (PTA; this is when the foot hits the ground) is strongly related to the shock or impact measured in the lab. As such, OnTracx allows measuring the impact or shock for every step, in an outdoor setting (where and when it really matters). This allows runners to work on injury prevention based on load measures. In addition to this, we’re also developing more advanced loading metrics. More on that soon!
Here it gets a bit scientific, but the correlation between the signal from the sensor and the laboratory measure shows a very strong correlation of r = 0.91.
This means that our sensor-based measure is almost the same as the load parameter calculated in lab-settings. As a spin-off from Ghent University and its Sport Science Laboratory - Jacques Rogge, we care about the accuracy and validity of our product, and do not aim to create something that looks good but doesn't really do the job.
Our measurements have been validated with the so-called ‘golden standard methods’. This means that we checked - and verified - that the load measured by Ontracx is similar to the one measured in specialized laboratory settings. This however doesn’t mean that our product is perfect. It just means we’re confident that what we’re measuring is correct enough to be used in real-world settings.
There are quite some other running tools out there, but they all have a different purpose compared to OnTracx.
While many other (wearable) technologies focus on how to improve performance, the focus of OnTracx completely lies in the injury prevention and return-to-run areas. We’re one of the first to quantify mechanical load in an evidence-based and reliable way, and translate this type of information to all runners out there, with only one goal: reduce the millions of running injuries worldwide.
We strategically placed the sensor on the lower leg because, during extensive testing, it proved to be the most reliable location to measure mechanical load during running. Here's why:
Specificity: The lower leg experiences the first rapid deceleration as your foot strikes the ground. Which only can be captured by measuring at that specific location.
Consistency: Unlike other locations, such as in the shoe, on the laces, or on the lower back, attaching the sensor around the lower leg minimizes interference from external factors and ensures your data reflects actual running load.
Validation: Through rigorous lab testing, we found that the lower leg provided the most accurate and reliable data.
It’s important to place the sensor the same way every time you go for a run. Here are some guidelines for proper sensor attachment:
Place the sensor about 10cm above your inner ankle, on the flat part of your shin bone. Always attach the strap firmly, in a similar way, and on the same leg (we advise to put it on the leg that suffers (most) from running injuries).
To make this more clear, we made a video that shows you how to attach it exactly!
In the return-to-run phase it is crucial that the perceived load on the body is built up gradually and in an objective manner. And this for several reasons:
The latter is called 'proper load management', and is exactly what OnTracx offers.
Unfortunately, that’s still possible.
Although most running injuries are caused by an excessive amount of mechanical load, they also depend on a variety of other parameters. This makes it very hard to estimate whether someone will get injured or not, as it is not straightforward to quantify and interpret each of the parameters and their mutual relationships.
However, knowing the individual load profile of patients can provide valuable information to prevent (re-)injury and to optimize the rehabilitation process. This is because mechanical load is considered the most important risk factor for overuse injuries in running, and should be increased gradually (based on objective data) in a return-to-run context.
OnTracx gives you the possibility to measure mechanical load in an objective manner, both in the clinic and outside of the clinic.
This means that OnTracx offers a huge advantage on several fronts during rehabilitation (and mainly during the return-to-run phase):
Simply put: no, there isn’t.
Current scientific evidence shows that there’s no such thing as a ‘perfect’ running style that every runner should adopt, when it comes down to injury prevention or rehabilitation of overuse injuries. There are two important aspects here to take into account:
Changes in running technique can thus be effective in reducing mechanical load, but it needs to be measured (on an individual level) to know this. Here, OnTracx can help in supporting the right intervention.
Especially tibial stress fractures, plantar fasciitis, Achilles tendinopathy and patellofemoral pain have been shown to be related to a very high variety of parameters of which an excessive amount of load is considered the most crucial one - by far! Based on the available literature, managing load has already been shown to be one of the most effective ways to successfully reduce the number of running injuries.
No, OnTracx is not a medical device.
However, our innovative technology is designed to effectively manage mechanical load on the lower legs during running. Although not a medical device, our solution can be very relevant for injury prevention or rehabilitation purposes. Always consult a healthcare professional for personalized medical advice.
