Summary:
- The article examines physiological and psychological differences between biological sexes in the context of ultra-endurance running, citing research on fatigue resistance and muscle fiber composition.
- It explores the "fatigue gap," noting that women often demonstrate a higher capacity to resist muscle fatigue during prolonged physical exertion compared to men.
- The piece contextualizes these findings within the broader scientific discourse on human performance, acknowledging that while evolutionary biology may play a role, individual training and metabolic efficiency remain critical variables.
