About Fibion. The Professional Sitting and Activity Analysis.

Fibion Story

The story of Fibion started from our passion to make sitting and activity measurement a credible, evidence-based tool for professionals.

The participants in our research projects were amazed when they saw the results of the accurate activity measurements. Our findings showed that people were spending the majority of their days sitting without even thinking about it. However, the evidence-based results motivated them to change their behaviour in an active, healthier direction.

We decided that this concept needed to be taken out of the laboratory to coaches who wanted to provide their customers with an easy, yet evidence-based and effective step toward healthy sitting and activity habits. This is the story of Fibion. Our mission to help people to help people.

From the start..

The idea towards Fibion was born from our scientific research to provide professionals with a credible and easy-to-use analysis for measuring sitting and everyday activity in order to achieve an evidence-based health impact.

To proudly summarise, Fibion is based on five break-through innovations.

Firstly the secret sauce is the advanced analysis algorithms to process the recorded data. The Fibion algorithms are based on our scientific research and hundreds of scientific research papers.
Secondly the analysis results and related recommendations are visualised and presented in an understandable way. We know because we asked people.
Thirdly Fibion is the first sitting and physical activity analysis report designed from the beginning for professional feedback and consultation - even group consultation.
Fourthly because the Fibion Device is worn next to the thigh, it can very accurately analyse different activities and their energy expenditure based on the movement of the thigh with almost perfect accuracy. Thus, the Fibion analysis gives more accurate results with a week-long measurement, than the consumer trackers are able to provide in habitual use.
Fifthly Fibion is easy to use. It does not have buttons or settings. Starting a measurement with Fibion takes less than a minute without collecting any background information from the person. The efficient customer process is thought-out for customer delivery; Fibion even includes an equipment pouch for the necessary gear. the goal.

Fibion has become not only the first, but also the most accurate and the easiest to use commercial professional level analysis tool available. It requires no prior training and cost the same as inaccurate consumer gadgets. Even your customer will understand the science of our visual reports.

Fibion is the InBody of activity measurement – the golden standard that you can trust.

The key combination accurate health data and professional consultation

It all started with our determination to get people out of their chairs

Several years ago, when the health hazards of sitting gained support from initial findings, we were launching our first research projects to quantify the sitting and physical activity habits of people with muscle activity measurement.

The test subjects were invited to our lab in the university. They were hooked up to big machines and put through many hours of scrutiny in order to collect the research data. These pioneer projects gave us a solid standpoint from which to develop the science and practise of our sitting and physical activity measurement.

As a part of these projects, we were giving interested people feedback about their everyday sitting and activity habits. People were amazed and scared when they saw the truth based on the accurate activity measurements: they were spending the majority of their days sitting without even thinking about it.

Yet, at the same time, the evidence-based results motivated them to change their behaviour toward living a more active lifestyle. As the project results pointed out, the key to the behaviour change was the combination of the accurately recorded data and the professional consultation regarding what the measurement actually revealed.

The opportunity

to help masses of people

presented itself

In the developed countries, millions of people are suffering from sedentary lifestyle, obesity, and the resulting health problems. A modern life is characterized by physical inactivity, which is fourth leading cause of premature death in western countries. Obesity, type 2 diabetes, cardiovascular diseases and musculoskeletal diseases cause a high burden for several stakeholders with accumulated costs rising up to tens of percents of GDP.

How to fit a lab into your pocket and other challenges to be tackled

This is the scientifically proven way how professionals will be able to encourage and motivate their customers away from a health damaging behavior, as we did with our research subjects.

We need to take our experiences and the analysis out of laboratory

Even if the analysis methodology proved itself, it involved cumbersome laboratory equipment, purpose-built scientific devices, and analysis software developed only for the researchers in the project. To operate this equipment, you were required to be a trained scientist, which we cannot require from everybody, can we?

Additionally, the measurement setting required tedious preparations and it was not overly reliable. Yet, along the way, the measurement process and the consultation feedback was iterated and improved in numerous incremental steps. We knew first hand that the whole process needed to be as easy and fluent as possible.

18 months

of additional R&D followed

Fibion was born and available for professionals in our online store in 2015. During the years of research and development, we collected and studied physical activity data from a great number of participants. We learned the hard way that every detail in the process needed to be in place.

Consequently, in Fibion, the smallest detail was considered, including everything to make the three-step experience - measurement, analysis, consulting - as easy and efficient as possible.


Sometimes innovations can be as simple as an equipment pouch that keeps everything in place and ensures that a small user guide will always be with your customer and that the personal background information form will never get lost. The pouch looks nice and is professional, too! Coaches can serve big groups of customers alone without collecting any personal background information beforehand, like weight and height: just hand out Fibion pouches.
When the measurements and pouches are returned, the coach can run an analysis immediately and provide combined feedback to groups, such as at work places, while handing the personal reports of all interested parties. The coach decides how much time to spend on feedback and consultation (15 minutes to an hour), while the entire customer process –through the report phase – can be done in less than five minutes.

We brought the science with us. The magic happens in our analysis algorithms.

Our secret sauce lies deep inside our cloud service. This is where the fruit of the years-long scientific research is located. The collected raw data is sent to our online service, where the data is crunched into visualised and portable reports. Internet technology and computer farms ensure that the reports are generated instantly.

To make sure our algorithms provide the latest knowledge for your coaching, we have collected data from hundreds of research papers and translated them for your benefit. We do our best to crystallise and visualise the collected information into attractive and understandable reports so that it is easy for the coach to convince his or her customers of the importance of everyday activities.

How do you replace expensive and difficult-to-use laboratory equipment?

The Fibion Device is based on a commonplace 3D accelerometer. This means that the device measures acceleration in three dimensions. However, the Fibion Device is significantly different from its competitors in several ways. It is very small and lightweight, and does not have any buttons. The Device is worn simply in the front pocket of the trousers. Fibion comes with a thigh strap so it can be worn even without a pocket.

It is not what you wear, but how you wear it

Based on the movement and position of the thigh, the Fibion Device is capable of detecting a set of body postures and movements that are difficult to detect otherwise, including sitting, standing, and cycling. In these activities, a device worn around the wrist or waist is very inaccurate, as the position of the device is similar during these activities, like working at a desk.

Validation Testing

TASK: Classify Activity by type

92.8% accuracy

in pocket

97.0% accuracy

with strap

Almost Perfect

In our own validity testing, we tested the ability of Fibion to classify several different sitting, standing, walking, cycling, and running activities in 12 different subjects.

Fibion classified the activity type correctly in 92.8% and 97.0% of the recorded time when worn in the pocket and on the thigh strap, respectively.

This result was very high, given that the inaccuracy of wrist-worn devices in measuring daily light intensity activities may result in very raw estimates of true activity time, if they can measure the activity difference at all.

For example, a wrist-worn device cannot recognize between sitting and standing next to a standing work desk.


Estimating Energy Expenditure

Market Leader
36.7% off

1.6% off

as compared to heart rate

We also compared Fibion to Actigraph in their ability to estimate energy expenditure using the heart rate as a reference method. The Actigraph is the most common device used in scientific research.

We found that, during simulated walking, running, and cycling activities with 19 subjects, Fibion underestimated energy expenditure by 1.6% as compared to heart rate. However, the Actigraph underestimated energy expenditure by 36.7%.

Thus, Fibion appeared to be more accurate than the Actigraph, which currently is the most widely utilised device in scientific physical activity research.

Validation Test Results

Fibion is to be worn for seven days during waking hours. This suggestion is based on scientific findings where a seven-day measurement tells about your sitting habits with 88% reliability. In other words, if you repeat the measurement the next week, the result is the same with 88% probability.
Based on the results, it is fair to say that Fibion provides more accurate data about sitting and physical activity habits with only one week of measurement than the consumer trackers are able to provide during habitual use.

Additionally, with Fibion, the consumer has access to a professional who can explain the results and the recommendations based on the results, whereas consumer devices leave the user alone to guess what the diagrams actually mean regarding health.
