ZoneX
For sports professionals who want to train athletes with precision and efficiency

Yes, ZoneX comes with a 2-year warranty. ZoneX is repairable after this period

Yes, ZoneX results are scientifically validated. Our device was tested in collaboration with the Grenoble hospital and the sports pathology department. The tests were conducted under the supervision of Dr. Stéphane Doutreleau , head of the Pulmonology-Physiology, Sports and Pathology department, who performs more than 3,000 stress tests per year . ZoneX was evaluated alongside reference hospital devices, under real-world conditions. The results demonstrated excellent agreement between ZoneX measurements and those of conventional systems, confirming the reliability of our technology for detecting ventilatory thresholds .

No, ZoneX requires no specific maintenance and no consumables. The breathing tube, through which the user inhales and exhales, is easily removable and must be cleaned and sterilized after each test, according to current hygiene standards, in particular in accordance with standard NF 26782. It can be cleaned in the dishwasher or with disinfectant tablets.

Yes, ZoneX is perfectly suited for serial testing for groups or teams. ZoneX comes with 3 internal tubes which allow for consecutive testing. A test tube must be washed after use (in water with a disinfectant tablet). It must then be dried before reuse. The same applies to the mask, which can be dried with a wipe.

The test protocol is the same as that used for stress tests in hospitals. 1. Setting up the equipment. If the test is being carried out on a bike, the bike must be mounted on a home trainer. For running, the test is carried out on a treadmill.ZoneX comes with software. This software connects to the ZoneX device and the heart rate sensor (optional). It also connects to the treadmill or ergometer to program the test protocol.The following sensors can be connected to the software:Heart rate sensorChoose a treadmill or ergometer bike connected via Bluetooth (BLE)You also have the option of synchronizing the results after the test with a FIT file. 2. The test (submaximal incremental test) Warm-up phase: 5 minutes at low intensity Progressive effort phase: Start at a moderate intensity (e.g., 100 watts on a bike or 6 km/h when running) Increase your speed (running) or power (cycling) in 1-minute increments Each increment should gradually increase the load by approximately 20 watts (cycling) and/or 0.5 km/h (running) To obtain your ventilatory thresholds, you perform a submaximal test, i.e., you just need to exceed threshold 2 slightly. With practice, you will be able to see this on the signals displayed in real time during the test.Of course, you can push yourself to the maximum to get your VMA (running) or PMA (cycling) results. 3. Data analysis and detection of ventilatory thresholds The PAIRFS software automatically analyzes the results to automatically detect thresholds. Once your test is complete, the software will display your ventilatory thresholds in power and bpm for cycling and in speed/pace and bpm for running. Ventilatory Threshold 1 (VT1): Significant increase in expiratory volume Transition from calm breathing to deeper breathing Ventilatory Threshold 2 (VT2): Onset of marked hyperventilation Hyperventilation becomes disproportionate to CO₂ production

No, ZoneX measures ventilatory thresholds from exhaled volume and CO2 in your breath.
