Cardiopulmonary exercise testing (CPET) is the reference standard for the direct measurement of maximal oxygen uptake (VO₂ max) and the precise determination of ventilatory thresholds (VT1 and VT2) in cycling, key markers of aerobic performance. Our incremental cycling protocol was scientifically validated against laboratory ergospirometry in a cohort of trained cyclists. The results were published in NPJ …
Experience and key insights from a Senior Program At CHASKi, we believe that measuring is not just about collecting numbers, but about creating experiences that help people and professional teams make better decisions. With that mindset, we recently took part in a series of 1000-meter track assessments conducted as part of a leading Senior Sports …
For decades, physiological testing for endurance athletes has been dominated by laboratory-based ergospirometry—bulky equipment, masks, and controlled environments. While these setups are the gold standard for measuring key markers like ventilatory thresholds (VT1, VT2) and respiratory rate (RR), they come with limitations: cost, accessibility, and an environment that often feels far removed from real racing …

Revolutionizing Performance Monitoring with CHASKi For endurance athletes, understanding ventilatory thresholds (VT1 and VT2) is crucial for optimizing training and maximizing performance. Traditionally, these thresholds are measured using ergospirometry—an accurate but cumbersome lab-based method. Now, with CHASKi, you can access the same gold-standard data in the field. But how well does it stack up against …

We recently conducted a preliminary study to further validate CHASKi’s technology against the gold standard on the treadmill. Similar to our cycling validation study, we are comparing CHASKi’s evaluation of ventilatory thresholds and respiratory frequency with ergospirometry. This study involved 14 volunteers of varying ages and sports disciplines. Our preliminary results show high agreement between CHASKi …
