Fatigue is a temporary decrease in performance under the influence of prolonged exposure to stress. It arises as a result of the depletion of the internal resources of the individual and the mismatch in the work of the systems that support the activity.
Fatigue has various manifestations on the behavioral (decrease in labor productivity, decrease in the speed and accuracy of work), physiological (difficulty in developing conditioned connections, increased inertia in the dynamics of nervous processes), psychological (decreased sensitivity, impaired attention, memory, intellectual processes, shifts in emotional motivational levels, accompanied by the formation of a complex of subjective experiences of fatigue.The specificity of manifestations of fatigue depends on the type of load, the localization of its impact, the time required to restore the optimal level of performance.
Fatigue, a set of changes in the physical and mental state of a person and an animal, developing as a result of activity and leading to a temporary decrease in its effectiveness. The subjective feeling of fatigue is called fatigue.
The dynamics of fatigue
The dynamics of working capacity includes phases: mobilization, i.e. preparation for activity, a primary reaction reflecting the process of quantitative balancing, hypercompensation, i.e. search for an optimal solution, compensation, when the working capacity is adequate to the requirements of the activity, subcompensation, decompensation and breakdown, reflecting the gradual depletion of the body's reserves and a decrease in working capacity. U. is characteristic of all phases, starting with subcompensation, when there is a significant reduction in physiological reserves and the body switches to energetically less favorable types of reactions, for example, maintaining the minute volume of blood flow by increasing the frequency of heart contractions instead of a more favorable reaction of increasing the stroke volume; the implementation of a motor reaction by a large number of functional muscle units with a weakening of the force of contractions of individual muscle fibers, i.e. violation of the alternation of periods of work and rest of the muscle groups involved in the contraction. In a person in the initial stages of U., the effectiveness of activity decreases, i.e. the amount of physiological and mental costs required for one and the same labor act increases; then labor productivity also falls. With fatigue, first of all, the stability of the autonomic functions, the strength and speed of muscle contraction are disturbed, the regulation of functions, the development and inhibition of conditioned reflexes deteriorate. As a result, the pace of work slows down, the rhythm, accuracy and coordination of movements are disturbed, for the same activity, large energy costs are required. The thresholds of sensory (sensitive) systems rise, stereotypical forms dominate in decision-making processes, attention is weakened and it is difficult to switch. Fatigue is characterized by an increase in the number of errors and a change in their structure: in the initial phases, quantitative errors dominate, in subsequent phases, qualitative ones appear. The development of the picture of fatigue can be generally characterized as a violation of the adequacy of the body's response to the requirements imposed by the nature of the activity. At the same time, all 3 basic requirements of adequacy are violated: the optimality of the particular reactions that underlie the activity and their coordination with each other, the qualitative and quantitative correspondence of the body's response to the requirements of the task and the minimization of the consumption of physiological reserves.
With pronounced fatigue, there is a complete cessation of work. Subjective signs of human fatigue - unpleasant sensations in working muscles and joints, with a static posture - pain and a feeling of swelling in the muscles of the back, abdomen and neck, the appearance of pain in the forehead and the back of the head, especially with sensory and mental fatigue, impaired concentration, easy distraction, at first some increase, and then a sharp limitation of contacts with others, an unconscious desire to make breaks from work more frequent and longer. Fatigue in animals and humans has a number of common mechanisms associated with biochemical changes at the cellular level and impaired conditioned reflex activity. However, both the dynamics and a number of structural mechanisms of fatigue, determined in humans by the regulating role of the motives of activity, its goals and social nature, make it possible to detect a number of fundamental differences in fatigue in animals and humans. In particular, in animals there is no strict development of the phases of fatigue, a sequential decrease in quantitative indicators is more characteristic, a change in the structure of activity is less pronounced, fatigue is practically not suppressed by volitional effort.
The dynamics of fatigue is influenced by the nature of the activity, primarily its intensity, extensiveness and pace. There is an optimal intensity of activity in which fatigue occurs later; an increase or decrease in this intensity accelerates the onset of fatigue. Fatigue develops rapidly during monotonous, static and sensory depletion of activity. So, during activities during which a person performs the same working operation for a long time, requiring a limited set of movements, for example, during highly specialized work on an assembly line (monotonous activity), attention decreases, positive motives of activity fade away and fatigue develops quickly. Fatigue appears especially early in those cases when work is performed with a fixed tense posture (static activity) or when the flow of stimuli arriving at a person is limited, for example, sound or light signals containing information about the conditions of activity. Of the external factors of the working environment, the microclimate is of great importance, especially temperature, humidity and air velocity, air composition and the presence of chemical impurities in it, noise, vibration, illumination, etc. The development of fatigue depends on the state of health and physical fitness of a person, which not only determine large physiological reserves, but also contribute to a faster and more stable mobilization and formation of functional systems. The rate of emergence and development of U. also depends on a number of psychological characteristics of the personality - the level of anxiety, volitional qualities, including persistence, and other activation parameters, i.e. such functional properties of a person, which provide the degree of realization in a specific activity of his potential. For example, attention as an activation parameter provides great opportunities for memorization, and a high level of volitional qualities allows you to maintain the required level of activity with a pronounced feeling of fatigue. The leading role belongs to the highest mental characteristics - ideals and worldview.
Types of fatigue
Depending on the type of work performed, mental and physical fatigue is distinguished, in which deviations of energy metabolic parameters are taken into account, for example, changes in body temperature, bioelectric potentials. Due to the fact that the fundamental commonality of physical and mental fatigue has been revealed, a classification based on the predominant localization of fatigue in the links of the nervous system that ensures human activity is becoming widespread. Thus, sensory fatigue and its varieties (perceptual and informational) and effector fatigue are distinguished. In addition, general fatigue is distinguished as a generalized form. However, this or that classification depends on the accepted physiological theory of fatigue. Sensory fatigue develops as a result of prolonged or intense exposure to a stimulus (for example, loud noise, light), in which primary changes occur in sensory systems, from the receptor to the cortical end of the analyzer. Perceptual fatigue, localized mainly in the cortical end of the analyzer, is associated with the difficulty of detecting a signal (for example, with large noise, with its low intensity, difficulty in differentiation). Information fatigue develops as a result of insufficient information or during information overload, when the greatest load falls on the dynamics of intercentral relations, which consists in closing temporary connections between various structures in the central nervous system and revitalizing associative connections, which make it possible to correctly reflect the objective picture of the external environment in consciousness. Effective fatigue occurs when changes are localized mainly in the parts of the central nervous system that form the motor act. With changes that appear as a result of intensive processes of reproductive activity, associated only with the processing of the information received according to strict rules (for example, counting, categorization by headings), as well as productive, including the processes of converting information and forming judgments, concepts, inferences, etc., and heuristic, i.e. creative, carried out according to individual, implicit algorithms, mental fatigue is formed. Due to the fact that during work, all of the listed changes are often combined, general fatigue is highlighted, while emphasizing the most pronounced disorders in the central nervous system.
