CHASKi on the Track: Lab-Grade Precision in the Real World

by Consuelo SotoEnglish, Science, Validation & Field UsePosted on No Comments

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 …

CHASKi: A Wearable Game-Changer for Endurance Athletes

by Consuelo SotoEnglish, Science, Validation & Field UsePosted on No Comments

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 …

Training at altitude with CHASKi

by Consuelo SotoEnglish, Science, Validation & Field UsePosted on No Comments

The benefits of altitude training Altitude training is common practice among endurance athletes seeking to improve performance. It is generally performed at > 2,000 meters (> 6,560 ft) above sea level and induces a series of physiological adaptations, such as increased production of red blood cells and hemoglobin, which improve the body’s ability to transport and utilize oxygen. These adaptations generate improved …
