CHASKi: A Wearable Game-Changer for Endurance Athletes

by Consuelo SotoEnglish, Science February 19, 2025February 20, 2025No 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 …

Ventilatory Thresholds vs. Lactate Thresholds: Are They Competitors or Complementary Metrics?

by Renee LeathermanEnglish, Science January 30, 2025No Comments

Ventilatory Threshold and Lactate: Complementary Metrics for Smarter Training In the world of endurance training, metrics reign supreme. From heart rate to power output, athletes rely on data to refine their training strategies and achieve peak performance. Among these metrics, ventilatory threshold (VT) and blood lactate levels stand out as two of the most insightful …

Introducción a la Respiración para Atletas de Resistencia

by Consuelo SotoCiencia, Español November 20, 2024November 27, 2024No Comments

La investigación sugiere que los patrones de respiración controlados e intencionados pueden influir de manera significativa en los resultados deportivos. Por ejemplo, se ha demostrado que ciertas técnicas de respiración mejoran el rendimiento de resistencia al optimizar la utilización de oxígeno y retrasar la aparición de la fatiga [1]. Otros estudios documentan cómo diferentes técnicas …

HIIT vs. Sprint Intervals: How to Optimize VO₂max for Endurance Athletes

by Consuelo SotoEnglish, Science November 19, 2024November 26, 2024No Comments

Maximal oxygen uptake (VO₂max) is the cornerstone of endurance performance, and two recent studies confirm that aerobic high-intensity interval training (HIIT) is superior to sprint interval training (SIT) in improving VO₂max for both men and women. For endurance coaches and self-educated athletes, these findings offer critical insights into structuring training programs for peak performance. Key Findings From …

Unlocking Performance Gains: The Power of Personalized Training Zones with CHASKi

by Consuelo SotoEnglish, Science October 28, 2024October 28, 2024No Comments

Understanding the science behind exercise testing and training intensity zones is key to optimizing performance for endurance athletes. At CHASKi, we emphasize the value of data-driven training based on ventilatory thresholds, and today we’ll explore why testing and threshold-based training are so impactful. We’ll also dive into a cyclist’s case study, showcasing how CHASKi helped …

Introduction to Breathwork for Endurance Athletes

by Renee LeathermanEnglish, Science October 26, 2024October 26, 2024No Comments

Research suggests that controlled, deliberate breathing patterns can dramatically affect sports outcomes. For instance, specific breathing techniques have been shown to enhance endurance performance by improving oxygen utilization and delaying the onset of fatigue[1]. Other studies have documented how different breathing techniques can either enhance or impair athletic performance, depending on their application, underscoring the …

Knowing When to Rest: How to Avoid Overtraining by Monitoring Recovery and Respiratory Rate

by Consuelo SotoEnglish, Science August 23, 2024August 23, 2024No Comments

Proper rest and recovery are essential components of any successful training program. At CHASKi, we believe that understanding when to take a break can help athletes avoid the pitfalls of overtraining. This post explores the principles of recovery, the differences between overreaching and overtraining, and how respiratory rate (RR) can serve as an indicator of …

Estimate Your Maximal Lactate Steady State Using Ventilatory Thresholds

by Consuelo SotoEnglish, Science July 22, 2024July 23, 2024No Comments

Understanding the maximal lactate steady state (MLSS) is crucial for endurance athletes, as it signifies the highest intensity one can sustain without causing significant intramuscular or blood pH imbalances. Essentially, MLSS is a key indicator for gauging endurance performance, reflecting the ability to maintain a high aerobic rate during prolonged exercise. Breakthrough Study: Ventilatory Thresholds …

CHASKi Running Validation Study: Preliminary Results

by Consuelo SotoEnglish, Science, Uncategorized June 25, 2024September 27, 2024No Comments

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 …

Estudio de Validación en Running con CHASKi: resultados preliminares

by Consuelo SotoCiencia, Español June 17, 2024September 27, 2024No Comments

Recientemente realizamos un estudio preliminar para continuar validando la tecnología de CHASKi frente al gold standard, esta vez, en trotadora. Al igual que nuestro estudio de validación en ciclismo, estamos comparando la evaluación de umbrales ventilatorios y frecuencia respiratoria de CHASKi con la ergoespirometría. Este estudio involucró a 14 voluntarios de diferentes edades y disciplinas …
