Your Breathing, Your Identity: The Science of Respiratory Fingerprints

by Consuelo SotoEnglish, Performance Monitoring & Metrics, SciencePosted on No Comments

A new study published in Current Biology reveals that each of us has a unique nasal respiratory fingerprint, an individually specific and stable pattern of breathing. This groundbreaking research shows that these “fingerprints” can be used to identify individuals with near-biometric accuracy and provide significant insights into a person’s physiology, emotional state, and even cognitive traits. For coaches and …

Why Monitoring RPE—and Comparing It to Respiratory Frequency—Matters More Than You Think

by Consuelo SotoEnglish, Performance Monitoring & Metrics, SciencePosted on No Comments

In endurance training, Rating of Perceived Exertion (RPE) has long been a trusted compass—an intuitive guide to how hard an athlete feels they’re working. But how reliable is this perception in real-time, especially under fatigue, heat, or glycogen depletion? More importantly, can we measure how well athletes are controlling their RPE, and should we compare what they …

Why Heart Rate Alone Isn’t Enough: Rethinking Performance Metrics

by Consuelo SotoEnglish, Performance Monitoring & Metrics, SciencePosted on No Comments

For decades, heart rate has been the go-to metric for athletes and coaches aiming to optimize performance. It’s convenient, widely accessible, and often seen as a universal marker of effort. However, heart rate is far from perfect. Recent research, including findings from the Journal of Sports Science and Medicine (Tocco, 2015), highlights significant limitations of …

Could Respiratory Rate Serve as a Superior Indicator of Physical Effort?

by Consuelo SotoEnglish, Performance Monitoring & Metrics, SciencePosted on No Comments

Metrics like heart rate, speed, and power have long been the gold standard for monitoring physical effort during exercise. However, emerging research suggests that respiratory rate (RR) could be a more reliable and insightful marker of exercise intensity. As coaches and athletes seek the most effective ways to optimize training, understanding the role of respiratory …
