Improve FTP, VO₂ and Power : Lessons from Elite Cyclists Using Isocapnic Training

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 […]

Isocapnic Validation Study

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 […]

Rethinking Respiratory Limits in Exercise

Review of: Barstow TJ, Murphy K, et al., “Respiratory Limitations during Exercise,” Current Opinion in Physiology, Volume 10, August 2019, pp. 173–179. For decades, we’ve assumed that in healthy individuals, the lungs and respiratory system are “overbuilt”—more than capable of handling the demands of even the most intense workouts. Recent research, however, paints a different picture. Three […]

Respiratory Muscle Training for Patients with COPD and Asthma

By: Dr. Andrew Sellars  Asthma and chronic obstructive pulmonary disease (COPD) share some similar symptoms, despite being caused by distinct underlying mechanisms. Both conditions often lead to expiratory wheezing—a raspy, whistling sound during exhalation—which is linked to an inability to fully exhale. This prolongs the exhalation phase of the breathing cycle and can result in shortness […]

How Respiratory Muscle Training Transforms Post-Covid Care

By: Dr Andrew Sellars A recently published article in the German Journal of Sports Medicine highlights the potential benefits of breath training for patients experiencing lingering symptoms following a Covid-19 infection. This study underscores the power of focused breathing exercises and innovative tools like the Isocapnic BWB device to support post-COVID lung recovery and improve overall respiratory health. One of the common post-Covid […]

The “Upside” of Sean Seale’s Respiratory Step Test

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 […]
