Which performance or physiological characteristic is NOT usually observed in a state of nonfunctional overreaching (NFOR) within athlete populations?

Which performance or physiological characteristic is NOT usually observed in a state of nonfunctional overreaching (NFOR) within athlete populations?

• A. Stagnation in performance
• B. Hormonal disturbances
• C. Sleep disturbances
• D. Increased levels of fatigue

Answer: (C)

Nonfunctional overreaching reflects a maladaptive response to excessive training with insufficient recovery, leading to a meaningful drop or stagnation in performance along with systemic signs. The most consistently seen features are a sustained performance plateau or decline and clear physiological disruptions, such as hormonal disturbances and an overall increase in perceived and actual fatigue. Sleep disturbances, while they can occur in some athletes under heavy stress or as part of broader overtraining syndromes, are not a reliable or defining characteristic of nonfunctional overreaching. They’re not typically used to identify NFOR across athlete populations, making them the least consistent sign among the options.
