Combat sports reward preparation, but they reveal truth. You might enter the cage sharper, stronger, faster, and smarter — but when your body slips into redline, skill becomes inaccessible and strategy fades into instinct. The fight becomes a negotiation between technique and physiology. The side with more physiological control dictates the pace, the chaos, and […]
Breathing is the most underrated performance system in the human body. You can have powerful legs, a strong heart, and elite conditioning — but if your respiratory system can’t keep up, everything else suffers. Athletes feel this as the familiar wall of breathlessness. Everyday people feel it as fatigue climbing stairs or during stress. Coaches […]
Dr. Andrew Sellars sat down for a conversation with Anthony from the Roadman Cycling Podcast to discuss his experience with integrating respiratory training into endurance training protocols. Check out the full podcast in audio form HERE OR Check out the video version here: Podcast summary and key points For decades, cyclists have obsessed over legs, […]
Elite professional cyclists already train at the edge of human capacity. Their lungs are huge, their hearts powerful, and their muscles efficient. Pushing their performance even a few percent higher is notoriously difficult. Yet a new study shows that adding Isocapnic respiratory training moved the needle for these world-class riders. If athletes at this level […]
A new study has just been published in the peer-reviewed journal Biology by Tomasz Kowalski of Warsaw, Poland. Keen observers may remember some of his earlier work with speed skaters and triathletes, which confirmed the physiologic benefits of respiratory muscle training. In his most recent publication, he investigates the effects of the BWB (Breathe Way […]
When it comes to elite CrossFit athletes, few names have commanded as much respect and admiration as Sara Sigmundsdóttir. Known for her fierce determination, powerful engine, and comeback resilience, Sara has been a podium threat at the CrossFit Games and a crowd favorite for years. And now, she’s turning heads once again — not just […]
Increase Muscle O₂ with Isocapnic Respiratory Muscle Training : An Independent analysis by high performance coach at SPACS Sport Physiology. As a sports physiologist and competitive age-group triathlete, I’ve always been fascinated by human performance. But after recovering from COVID-19, my interest in the respiratory system and its impact on endurance deepened even further. I […]
Cyril Ricci’s latest research, Developments and Adaptations of the Ventilatory System after 11 Months of Specific Training, is a game-changer in the world of performance training. This study delivers compelling evidence that structured ventilatory training, centered around isocapnic methods, produces substantial improvements in both inspiratory and expiratory capacities—validating the principles we’ve long championed with the […]
In the realm of fitness and performance, understanding the intricacies of physiological responses to exercise is paramount. One individual pushing the boundaries of conventional assessments is Sean Seale from Upside Strength. In his recent YouTube video, Seale introduces viewers to an innovative approach called the Incremental Respiratory Step Test, shedding light on the physiological nuances […]
This is not a full list of Isocapnic training benefits. That list would be equally long and varied.Instead, here are 20 common ways to design sessions for different goals. If you wonder what to do with the Isocapnic BWB, this guide will get you started. 1. Learn to Breathe Efficiently Using Isocapnic training for better […]
