The Science behind OMbra

What biosignals does the OMbra capture and how?

Heart rate:
3 electrodes on the inside of the band capture your heart’s electrical signal (ECG) at the core.

Sensor embedded into the band captures inhalations and exhalations in order to determine your breathing rate and depth.

Accelerometer inside the OMbox captures the direction and force of impact of your body’s movement.

How are the Smart Zones calculated?

OMsignal's technology narrows down on your body’s Ventilatory Threshold (VT) and Anaerobic Threshold (AT) by measuring your breathing while you run.

It then translates that to your corresponding heart rate in order to delimit your 3 Smart Zones.

It takes 5 runs to accurately determine your specific VT and AT and personalize your Smart Zones. Your Smart Zones adapt with you as you get more fit.


Why is it important to run in different zones?

Low-intensity runs (Endurance zone) strengthen the cardiovascular system (heart, mitochondria, capillaries), help the body burn fatefficiently and fend off soreness and fatigue.

High-intensity runs (Peak zone) develop speed, power and physical strength.

Moderate-intensity runs (Race zone) aren't bad; they're just not as productive. You're not getting as much body-adapting benefits of high intensity or conditioning benefits of low intensity. You are however creating fatigue, which leads to injury.

What are the Ventilatory and Anaerobic Thresholds?

Ventilatory and Anaerobic Thresholds are physiological thresholds that characterize specific changes in your breathing and metabolism during physical exercise.

These thresholds are specific to your body and vary from person to person.

Ventilatory Threshold (VT): you cross this threshold when your breathing suddenly gets much faster but you still feel in control of it. At this point your body starts partially tapping into its anaerobic metabolism (energy from carbohydrates) for the increased demand in energy.

Anaerobic Threshold (AT): you cross this threshold when you start feeling like you can no longer control your breathing. At this point your body is mostly using its anaerobic metabolism to sustain the high demand in energy.

What is Breathing Rhythm?

Breathing rhythm refers to the act of breathing in a set pattern along with stride (e.g. 4 steps / breath).

The more you keep your breathing rhythmic the more you reduce the workload on your respiratory muscles, which can use up to 15% of your energy expenditure.
