Overexertion
Exertion is the physical or perceived use of energy.Newton's Third Law, Elert, Glenn. “Forces.” ''Viscosity – The Physics Hypertextbook'', physics.info/newton-first/. Exertion traditionally connotes a strenuous or costly ''effort'', resulting in generation of force, initiation of motion, or in the performance of work. It often relates to muscular activity and can be quantified, empirically and by measurable metabolic response. Physical In physics, ''exertion'' is the expenditure of energy against, or inductive of, inertia as described by Isaac Newton's third law of motion. In physics, force exerted equivocates work done. The ability to do work can be either positive or negative depending on the direction of exertion relative to gravity. For example, a force exerted upwards, like lifting an object, creates positive work done on that object. Exertion often results in force generated, a contributing dynamic of general motion. In mechanics it describes the use of force against ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Humility And Struggle
Humility is the quality of being humble. Dictionary definitions accentuate humility as a low self-regard and sense of unworthiness. In a religious context humility can mean a recognition of self in relation to a deity (i.e. God), and subsequent submission to that deity as a member of that religion.Humility, The Catholic encyclopedia, Herbermann et al. (Editors), Vol 7, 1910, pp 543-544Humility, The Protestant theological and ecclesiastical encyclopedia, Herzog et al (Editors), Vol 2, 1860, pp 598-599 Outside of a religious context, humility is defined as being "unselved", a liberation from consciousness of self, a form of temperance that is neither having pride (or haughtiness) nor indulging in self-deprecation. Humility is an outward expression of an appropriate inner, or self regard, and is contrasted with humiliation which is an imposition, often external, of shame upon a person. Humility may be misappropriated as ability to suffer humiliation through self-denouncements which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biomechanics
Biomechanics is the study of the structure, function and motion of the mechanical aspects of biological systems, at any level from whole organisms to organs, cells and cell organelles, using the methods of mechanics. Biomechanics is a branch of biophysics. In 2022, computational mechanics goes far beyond pure mechanics, and involves other physical actions: chemistry, heat and mass transfer, electric and magnetic stimuli and many others. Etymology The word "biomechanics" (1899) and the related "biomechanical" (1856) come from the Ancient Greek βίος ''bios'' "life" and μηχανική, ''mēchanikē'' "mechanics", to refer to the study of the mechanical principles of living organisms, particularly their movement and structure. Subfields Biofluid mechanics Biological fluid mechanics, or biofluid mechanics, is the study of both gas and liquid fluid flows in or around biological organisms. An often studied liquid biofluid problem is that of blood flow in the human card ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Will (sociology)
In sociology, will is a concept introduced by Ferdinand Tönnies in "'' Gemeinschaft und Gesellschaft''", 1887. Tönnies' approach was very much indebted to Spinoza's dictum ''voluntas atque intellectus unum et idem sunt'' ("will as well as ratio are one and the same"), and to Arthur Schopenhauer. Tönnies saw a fundamental cleavage between "essential will" (''Wesenwille'') creating community (''Gemeinschaft''), and "arbitrary will" (''Kürwille''), creating society (''Gesellschaft'') - ''see'' Ferdinand Tönnies. See also * Neuroscience of free will *Voluntarism (action) Voluntarism, sometimes referred to as voluntary action, is the principle that individuals are free to choose goals and how to achieve them within the bounds of certain societal and cultural constraints, as opposed to actions that are coerced or p ...

Ferdinand Tönnies
Ferdinand Tönnies (; 26 July 1855 – 9 April 1936) was a German sociologist, economist, and philosopher. He was a significant contributor to sociological theory and field studies, best known for distinguishing between two types of social groups, Gemeinschaft and Gesellschaft (''community and society''). He co-founded the German Society for Sociology together with Max Weber and Georg Simmel and many other founders. He was president of the society from 1909 to 1933, after which he was ousted for having criticized the Nazis. Tönnies was regarded as the first proper German sociologist and published over 900 works, contributing to many areas of sociology and philosophy. Tönnies, Max Weber, and Georg Simmel are considered the founding fathers of classical German sociology. Though there has been a resurgence of interest in Weber and Simmel, Tönnies has not drawn as much attention. Biography Early life He was born on 26 July 1855 on the Haubuarg "De Reap," Oldenswort on t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Decision Theory
Decision theory (or the theory of choice; not to be confused with choice theory) is a branch of applied probability theory concerned with the theory of making decisions based on assigning probabilities to various factors and assigning numerical consequences to the outcome. There are three branches of decision theory: # Normative decision theory: Concerned with the identification of optimal decisions, where optimality is often determined by considering an ideal decision-maker who is able to calculate with perfect accuracy and is in some sense fully rational. # Prescriptive decision theory: Concerned with describing observed behaviors through the use of conceptual models, under the assumption that those making the decisions are behaving under some consistent rules. # Descriptive decision theory: Analyzes how individuals actually make the decisions that they do. Decision theory is closely related to the field of game theory and is an interdisciplinary topic, studied by economi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volition (psychology)
Volition or will is the cognitive process by which an individual decides on and commits to a particular course of action. It is defined as purposive striving and is one of the primary human psychological functions. Others include affect (feeling or emotion), motivation (goals and expectations), and cognition (thinking). Volitional processes can be applied consciously or they can be automatized as habits over time. Most modern conceptions of volition address it as a process of conscious action control which becomes automatized (e.g. see Heckhausen and Kuhl; Gollwitzer; Boekaerts and Corno). Overview '' Willpower'' and ''volition'' are colloquial and scientific terms (respectively) for the same process. When a person ''makes up their mind'' to do a thing, that state is termed 'immanent volition'. When we put forth any particular act of choice, that act is called an emanant, executive, or imperative volition. When an immanent or settled state of choice controls or governs a series ...

Psychological Inertia
Psychological inertia is the tendency to maintain the status-quo (or default option) unless compelled by a psychological motive to intervene or reject this. Psychological inertia is similar to the status-quo bias but there is an important distinction in that psychological inertia involves inhibiting any action, whereas the status-quo bias involves avoiding any change which would be perceived as a loss. Research into psychological inertia is limited, particularly into its causes, but it has been seen to affect decision-making by causing individuals to automatically choose or prefer the default option, even if there is a more beneficial option available to them, unless motivated to reject this option. For example, psychological inertia may cause individuals to continue with their investments later than they should, despite information telling them otherwise, causing them to suffer greater losses than they would have if they had disinvested earlier. Psychological inertia has also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cost
In production, research, retail, and accounting, a cost is the value of money that has been used up to produce something or deliver a service, and hence is not available for use anymore. In business, the cost may be one of acquisition, in which case the amount of money expended to acquire it is counted as cost. In this case, money is the input that is gone in order to acquire the thing. This acquisition cost may be the sum of the cost of production as incurred by the original producer, and further costs of transaction as incurred by the acquirer over and above the price paid to the producer. Usually, the price also includes a mark-up for profit over the cost of production. More generalized in the field of economics, cost is a metric that is totaling up as a result of a process or as a differential for the result of a decision. Hence cost is the metric used in the standard modeling paradigm applied to economic processes. Costs (pl.) are often further described based on thei ...

Energy
In physics, energy (from Ancient Greek: ἐνέργεια, ''enérgeia'', “activity”) is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light. Energy is a conserved quantity—the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The unit of measurement for energy in the International System of Units (SI) is the joule (J). Common forms of energy include the kinetic energy of a moving object, the potential energy stored by an object (for instance due to its position in a field), the elastic energy stored in a solid object, chemical energy associated with chemical reactions, the radiant energy carried by electromagnetic radiation, and the internal energy contained within a thermodynamic system. All living organisms constantly take in and release energy. Due to mass–energy equivalence, any o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Exercise
Exercise is a body activity that enhances or maintains physical fitness and overall health and wellness. It is performed for various reasons, to aid growth and improve strength, develop muscles and the cardiovascular system, hone athletic skills, weight loss or maintenance, improve health, or simply for enjoyment. Many individuals choose to exercise outdoors where they can congregate in groups, socialize, and improve well-being as well as mental health. In terms of health benefits, the amount of recommended exercise depends upon the goal, the type of exercise, and the age of the person. Even doing a small amount of exercise is healthier than doing none. Classification Physical exercises are generally grouped into three types, depending on the overall effect they have on the human body: * Aerobic exercise is any physical activity that uses large muscle groups and causes the body to use more oxygen than it would while resting. The goal of aerobic exercise is to inc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sport Psychology
Sport psychology was defined by the European Federation of Sport in 1996, as the study of the psychological basis, processes, and effects of sport. Otherwise, sport is considered as any physical activity where the individuals engage for competition and health. Sport psychology is recognized as an interdisciplinary science that draws on knowledge from many related fields including biomechanics, physiology, kinesiology and psychology. It involves the study of how psychological factors affect performance and how participation in sport and exercise affect psychological and physical factors. Sport psychologists teach cognitive and behavioral strategies to athletes in order to improve their experience and performance in sports. In addition to instruction and training of psychological skills for performance improvement, applied sport psychology may include work with athletes, coaches, and parents regarding injury, rehabilitation, communication, team building, and career transitions.

Cortisol
Cortisol is a steroid hormone, in the glucocorticoid class of hormones. When used as a medication, it is known as hydrocortisone. It is produced in many animals, mainly by the '' zona fasciculata'' of the adrenal cortex in the adrenal gland. It is produced in other tissues in lower quantities. It is released with a diurnal cycle and its release is increased in response to stress and low blood-glucose concentration. It functions to increase blood sugar through gluconeogenesis, to suppress the immune system, and to aid in the metabolism of fat, protein, and carbohydrates. It also decreases bone formation. Many of these functions are carried out by cortisol binding to glucocorticoid or mineralocorticoid receptors inside the cell, which then bind to DNA to impact gene expression. Health effects Metabolic response Metabolism of glucose In general, cortisol stimulates gluconeogenesis (the synthesis of 'new' glucose from non-carbohydrate sources, which occurs mainly ...
