The technology was validated in a clinical study conducted with the Grenoble University Hospital. This article details the principle and methodology. A technology for measuring ventilatory thresholds PAIRFS' first products are designed for sports professionals and athletes and allow for the measurement of ventilatory thresholds. The objective of the measurement is to determine the exercise intensities to which these thresholds correspond. Training zones and thresholds. More i

Analyzing gas exchange – VO₂, VCO₂, ventilation – is now the gold standard for understanding exercise physiology, determining ventilatory thresholds, and personalizing training. However, the market offers highly contrasting technological approaches: on the one hand, cumbersome, complex, expensive, but extremely precise systems; on the other, much more affordable and simpler devices, but with limited accuracy. This article discusses data quality, trade-offs, and why PAIRFS dec

Connected devices have transformed training: heart rate, power, cadence, speed, oxygen saturation… but one essential parameter is still largely absent from current wearables: breathing . However, breathing is the most direct, sensitive and reliable physiological signal for understanding what is happening in an athlete's body. After years of innovations focused on cardio and power, a new generation of sensors is emerging: respiratory wearables . And this revolution begins no

And how does this fit into the long-term vision of a portable CPET? In endurance sports, breathing is one of the most powerful physiological signals. Yet, measuring respiratory gases remains a complex field, dominated by cumbersome, expensive systems reserved for laboratories. At PAIRFS, we want to change that: to make key metabolic information accessible to all athletes , on the field, during training. But to achieve this, one fundamental rule must be respected: 👉 Don't me
