Breathing Frequency: The Overlooked Metric

This chapter discusses the importance of breathing frequency as a critical measure in endurance sports, drawing on groundbreaking research that correlates it with training stress and performance. It explores the development of a wearable technology designed to accurately measure breathing frequency, as well as its potential to enhance athletic assessment by serving as an objective metric of effort. The chapter highlights the physiological mechanisms behind breathing regulation, particularly the role of carbon dioxide management during physical exertion.
