Editorial on the Research Topic From Physiological Adaptations to Endurance Performance: It Is Time to Bridge the Gap Endurance Performance: A Vast Worksite At first glance, endurance performance appears relatively simple as it relates to the efficiency of the aerobic metabolism through the cascade of oxygen transfer from inspiration of atmospheric oxygen down to tissue mitochondria (Hoppeler, 2018). Yet, despite the profusion of research on endurance performance (i.e., >30,000 "endurance physiology"-related studies available on Pubmed within a century), there is a mismatch between endurance performance per se and its underlying physiological mechanisms. Indeed, studies rarely link athletes' performance/profile and their physiological adaptation in response to a given training or ergogenic intervention. In order to identify and understand the physiological adaptations that directly translate into enhanced endurance performance, this Research Topic intended to mobilize the scientific community to connect physiological adaptations [e.g., maximal oxygen consumption (VO2max)], mitochondrial content) with endurance performance (e.g., power output, time, distance) in a single- or multi-disciplinary sports (e.g., marathon or triathlon).
