Fatigability refers to the susceptibility to fatigue or the tendency to become easily tired.
Fatigability is a noun derived from the adjective "fatigable", which refers to the capacity or tendency to become fatigued or tired easily. It describes a person's or organism's susceptibility to experience a state of mental or physical exhaustion due to prolonged or strenuous activity.
In the context of physical exertion, fatigability refers to the ease with which muscles tire or become exhausted during exercise or work. Individuals with high fatigability may find themselves quickly drained of energy and unable to sustain their physical efforts for an extended period of time. This can manifest as muscle weakness, decreased endurance, or a reduced ability to perform tasks that require physical strength or stamina.
Fatigability can also be applied to mental or cognitive processes. It describes an individual's tendency to experience mental exhaustion or diminished cognitive functioning after prolonged periods of mental effort or concentration. Those with high mental fatigability may struggle to maintain focus, experience a decline in attention span, or find it difficult to retain information or make decisions after prolonged mental exertion.
Factors such as overall health, fitness level, lifestyle choices, and underlying medical conditions can influence a person's fatigability. Some individuals may naturally exhibit higher levels of fatigability due to genetic or physiological factors, while others may experience increased fatigability as a result of lifestyle habits or certain medical conditions.

The word "fatigability" is derived from the root word "fatigue", which originated from the French term "fatiguer" meaning "to tire". It entered the English language in the 17th century and developed into the noun "fatigue", defining a state of mental or physical exhaustion. The suffix "-ability" is added to "fatigue" to form "fatigability", which describes the quality or state of being susceptible to fatigue or easily tired.
