What if your breath could tell you more about your fitness than your heart rate or power meter? In this episode of Performance Process, Ronan Mc Laughlin is joined by Arnar Lárusson, founder of Tymewear, to explore the growing role of breathing sensors in cycling.
Together, they unpack how real-time measurements of breathing frequency and ventilation can give athletes unprecedented insight into their true physiological stress, sometimes revealing limits before your heart rate or power ever do.
Arnar explains the science behind ventilation, how Tymewear’s sensor works, why breathing frequency is emerging as a reliable proxy for perceived exertion, and how this technology is already being used in the pro peloton.
