The HMOX2 polymorphism contributes to the carotid body chemoreflex in European sea-level residents by regulating hypoxic ventilatory responses

Frontiers in Medicine, 2022
This study investigates whether a functional single nucleotide polymorphism of HMOX2 (heme oxygenase-2) (rs4786504 T>C) is involved in individual chemosensitivity to acute hypoxia, as assessed by ventilatory responses, in European individuals.

Translating Fatigue to Human Performance [PDF]

Medicine & Science in Sports & Exercise, 2016
Despite flourishing interest in the topic of fatigue-as indicated by the many presentations on fatigue at the 2015 Annual Meeting of the American College of Sports Medicine-surprisingly little is known about its effect on human performance. There are two main reasons for this dilemma: 1) the inability of current terminology to accommodate the scope of ...

Fatigue Performance Of High-Modulus Basalt Fiber-Reinforced Asphalt Mixture

Journal of Applied Science and Engineering, 2023
An effective way to improve the rutting resistance of asphalt pavement is to increase the modulus of the middle surface layer of the asphalt mixture. However, the fatigue performance of high-modulus asphalt mixtures hinders this development.
