Integrating biomechanics into endurance performance frameworks: an urgent need

to the editor: We read with interest the recent Viewpoint by Meixner et al. (1), which proposes a conceptual expansion of endurance performance through four constructs: durability, fatigability, repeatability, and resilience. The authors rightly point out that the classical physiological markers are insufficient to fully account for individual differences in performance, particularly in competitive settings involving prolonged or repeated efforts. In response, they advocate for a multidimensional framework to better capture the complexity of endurance across disciplines and situations.
