How does GRASPOR work? What does GRASPOR measure, and how can I use that in my training? And how does the measurement work?
The availability of oxygen in your muscles is vital for endurance sports. Oxygen is the fuel to your muscles, which is why every endurance athlete should measure it.
Based on an advanced technology originally developed for astronauts, we have re-developed the technology for cyclists and runners, so you can measure your level of muscle oxygen in real-time when you’re out training.
When measuring it, you can improve it.
Technology
GRASPOR emits light from two different sources and measure the returning light at three different sites.
The light sources shines through your muscle and measures the intensity of the light returning to the sensor.
The intensity of the light is then used to calculate your muscle oxygen level. This calculation is made 10 times per second, allowing you to rely on live data throughout your workout.
space tech – not rocket science
Developed for space – optimized for earth
The technology behind GRASPOR was originally developed for astronauts. But just because it’s space tech, doesn’t mean it’s rocket science.
Simply put, we took an advanced technology, optimized it for you to use by turning it into one single number to manage your training intensity.
One number to rule them all.
GRASPOR dispels the myth of training based on the saying:
No pain, No gain.
What we measure
GRASPOR measures the oxygen level inside your muscles. This gives a clear understanding about exaclty how hard you are pushing your body at a certain intensity. Having this data available gives you the possibility to train based on an actual performance indicator, as oppoesed to power or heart rate.
When using power as a performance marker, you put all your trust in an external measurement. Simply put, the power meter only measures how hard you’re pushing the pedal. It doesn’t tell you anything about how much you’re stressing your body to apply the force into your pedals.
This is what GRASPOR can tell you.
GRASPOR gives you a clear understanding about what happens inside your body when on the bike. You can see exactly when you’re pushing too hard, or not hard enough.

What is muscle oxygen?
GRASPOR measures the number of oxygenated haemoglobin cells in your blood, compared to your total amount of haemoglobin cells. This means that if you have a Muscle Oxygen level of 54%, 54% of your haemoglobin cells carry oxygen at that moment. Your body requires oxygen to perform, as oxygen is a part of the process to create the energy your muscles use as fuel.
So, the harder you work, the higher the demand for oxygen, and therefore a lower Muscle Oxygen.
How it works
Muscle Oxygen has similar applicability to the blood lactate level. You can use Muscle Oxygen to measure the intensity of the work the body is performing in real time.
The major difference is that you can measure it without poking a hole in your finger to analyze the blood. This is because GRASPOR uses infrared light, that shines through your leg to measure your muscle oxygen value.
The intensity is impacted by the amount of oxygenated blood cells. The more oxygen present in the muscle, the more intense light is returned.

GRASPOR vs. status quo
GRASPOR is not a competitor to your power meter or heart rate monitor.
We love the power meter as much as you do. We just want to go above and beyond existing performance markers. We want to give you a tool to measure how hard you are working to deliver an output.
Below is an outline of the major differences between your power meter, heart rate monitor and GRASPOR.
Heart rate
Subtitle goes Here- Easy to begin using
- Measures heart beats per minute
- Less reliable as data is affected by outside factors like, sleep, clothing, caffeine, fatigue.
- High variablity from day-to-day
- Limited potential due to reliability and delay
GRASPOR
- Measures oxygen levels in the muscle
- Not impacted by external factors
- The only way to get your anaerobic and aerobic threshold
- Allows you to train based on adaptive training zones
- Pro level tests – on your own
- Improved warm-up’s
- Easy to use on all your bikes, or off the bike
- Requires an interest in training and some effort to use
Power meter
- External measurement
- More accurate than heart rate
- Measures the force applied to the pedal
- Not affected by external factors like, sleep, clothing, caffeine.
- Doesn’t measure actual intensity
- Intensity can change from day to day
