Nasal vs Oral Breathing During Exercise: What Happens as Intensity Increases

by Consuelo SotoBreathwork, English, Performance, Science, Validations March 17, 2026March 17, 2026No Comments

How breathing patterns shift across ventilatory thresholds and what it means for endurance training, exercise physiology, and respiratory efficiency. Breathing is one of the most important physiological processes during exercise, yet it is rarely something athletes or coaches actively observe. As exercise intensity increases, the way we breathe changes significantly. Understanding the transition between nasal …

Breathing Patterns and Lung Function: What Endurance Athletes Can Learn from Recent Research

by Consuelo SotoBreathwork, Performance, Science March 13, 2026No Comments

Breathing is the most constant movement we perform throughout the day. Yet it is also one of the least examined aspects of human physiology. For endurance athletes and coaches, breathing is usually associated with ventilation, oxygen uptake, and the response to exercise intensity. But recent research suggests that something even more basic may matter just …

Breathwork for Endurance Athletes: How to Integrate Breathing Training Into Your Program

by Consuelo SotoBreathwork, English, Performance, Science March 10, 2026No Comments

In recent years, breathwork has moved from yoga studios and mindfulness apps into the world of performance training. Coaches and athletes are increasingly recognizing that breathing is not only a passive process but also a trainable component of physiology. For endurance athletes in particular, the way we breathe influences efficiency, recovery, and the interaction between …

CHASKi Validation in Cycling

by Consuelo SotoEnglish, Science, Validations February 24, 2026No Comments

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 …

Validación de CHASKi en Ciclismo

La ergoespirometría es el estándar de referencia para la medición directa del consumo máximo de oxígeno (VO₂ max) y la determinación precisa de los umbrales ventilatorios (VT1 y VT2) en ciclismo, considerados indicadores clave del rendimiento aeróbico. Nuestro protocolo incremental en bicicleta fue validado científicamente frente a ergoespirometría en una muestra de ciclistas entrenados. Los resultados fueron publicados …

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

by Consuelo SotoEnglish, Science, Validations August 14, 2025February 12, 2026No 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 …

Breaking your limits: how to train and improve VT2 for high intensity

by Consuelo SotoEnglish, Performance, Science July 23, 2025February 18, 2026No Comments

In our constant pursuit of unraveling the secrets of endurance performance, we’ve already explored the First Ventilatory Threshold (VT1) as the foundation of our endurance. Today, we’ll raise the intensity to understand the next physiological milestone: the Second ventilatory threshold (VT2). What is the Second Ventilatory Threshold? The Second Ventilatory Threshold, commonly known as VT2 or also called …

En nuestra constante búsqueda por desentrañar los secretos del rendimiento en endurance, ya hemos explorado el Primer Umbral Ventilatorio (VT1) como la base de nuestra resistencia. Hoy, elevaremos la intensidad para comprender el siguiente hito fisiológico: el Segundo Umbral Ventilatorio (VT2). ¿Qué es el Segundo Umbral Ventilatorio? El Segundo Umbral Ventilatorio, comúnmente conocido como VT2 o también llamado …

First Ventilatory Threshold (VT1): The physiological key to your endurance performance

by Consuelo SotoEnglish, Performance, Science July 1, 2025February 18, 2026No Comments

As experts in physiology and performance, we know that endurance success lies in deeply understanding our body’s signals. Today, we’ll delve into a fundamental concept for athletes and coaches: the First Ventilatory Threshold (VT1). The First Ventilatory Threshold, or VT1, is a critical physiological point during progressive exercise. It represents the exercise intensity at which a …
