#fatigue

• Shot peening — The act of shot-peening and its result; an industrial technological operation of shot-blasting, hardening, or finishing metals, performed by projecting a dense jet of metallic pellets onto a surface. This structural process modifies the mechanical properties of the surface layer, inducing compressive stresses that prevent crack propagation, eliminate oxidation, and prepare the material for subsequent galvanic coating or painting.
• Endurance — The capacity of an organism, an athlete, or a mechanical and technical system to withstand prolonged heavy physical effort, intense stress, fatigue, or wear without structural degradation or significant drops in performance.
• Asthenia — The definite articulated form of the noun 'astenie'; it represents a pathological state of chronic fatigue, intense exhaustion, decreased muscular strength, and lack of physical or mental energy that does not disappear after rest; it often manifests during seasonal transitions or as a secondary symptom in infectious, endocrine, or neurological conditions.
• Exhausted — Having been brought into a state of asthenia; weakened, physically or nervously exhausted, lacking energy and vigor following a prolonged illness, intense intellectual effort, or chronic stress.
• Asthenic — Relating to asthenia or characterized by asthenia; an element, symptom, or organism marked by weakness, lack of energy, or chronic fatigue; as a noun or typological adjective, it denotes a person with a slender, longilinear physical constitution, narrow chest, and fine musculature, associated in biotypology with a temperament prone to introversion and sensitivity.
• Asthenic — The feminine form of the word 'astenic'; it refers to a person or a manifestation characterized by organic weakness, exhaustion, or chronic fatigue; in psychology and anthropology, it describes a woman with a slender, longilinear physical constitution, fine musculature, and a narrow chest, associated with a sensitive and introverted temperament.
• Asthenia — A pathological state of chronic fatigue, profound exhaustion, and decreased muscular strength, accompanied by a diminution of physical and mental energy that does not disappear after rest; it manifests as a core symptom during seasonal transitions or within endocrine, neurological, or infectious conditions.
• Debilitation — The act of weakening or bringing into a state of asthenia and its result; the physiological or psychological process through which an organism is reduced to a state of profound weakness, chronic exhaustion, or loss of vital strength, as a consequence of overwork, disease, or unfavorable environmental factors.
• Enervation — The act of enervating or bringing into a state of asthenia and its result; the medical, physiological, or psychological process through which an organism is reduced to a state of exhaustion, profound weakness, or loss of vital energy; physical or nervous overwork caused by pathogenic factors, stress, or overloading effort.
• Enervated — Having been brought into a state of asthenia; weakened, exhausted, depleted, or lacking physical and mental energy following chronic fatigue, prolonged stress, or illness.
• Asthenocoria — A rare ophthalmological condition characterized by an extremely slow, sluggish, or delayed accommodation reaction of the pupil to light stimuli (affecting both constriction and dilation), associated with local muscular or nervous fatigue of the iris, without implying a complete paralysis of the pupillary reflex.
• Asthenology — A theoretical branch or specialized medical study dealing with the detailed research, classification, and treatment of all forms of asthenia, organic weakness, and physical or mental exhaustion; it investigates the metabolic, endocrine, or neurological causes determining the collapse of energy barriers in the human body.
• Asthenomania — A rare mental disorder or obsessive preoccupation characterized by a person's deliberate simulation, exaggeration, or morbid focus on states of weakness, fatigue, and asthenia, often used as an unconscious or conscious mechanism to gain attention, sympathy, or social advantages.
• Asthenopia — An ophthalmological condition manifested by rapid visual fatigue, accompanied by headaches, tearing, blurred vision, and a burning sensation in the eyes; it usually occurs following prolonged visual effort (reading, computer work) or due to improperly corrected refractive errors (hyperopia, astigmatism).
