Physical Fitness
Physical fitness is a state of health and well-being and, more specifically, the ability to perform aspects of Outline of sports, sports, occupations, and daily activities. Physical fitness is generally achieved through proper nutrition, moderate-vigorous physical exercise, and sufficient rest along with a formal recovery plan. Before the Industrial Revolution, fitness was defined as the capacity to carry out the day's activities without undue fatigue or lethargy. However, with automation and changes in lifestyles, physical fitness is now considered a measure of the body's ability to function efficiently and effectively in work and leisure activities, to be healthy, to resist hypokinetic diseases, to improve immune system function, and to meet emergency situations. Overview Fitness is defined as the quality or state of being fit and healthy. Around 1950, perhaps consistent with the Industrial Revolution and the treatise of World War II, the term "fitness" increased in wester ...

Triangle
A triangle is a polygon with three corners and three sides, one of the basic shapes in geometry. The corners, also called ''vertices'', are zero-dimensional points while the sides connecting them, also called ''edges'', are one-dimensional line segments. A triangle has three internal angles, each one bounded by a pair of adjacent edges; the sum of angles of a triangle always equals a straight angle (180 degrees or π radians). The triangle is a plane figure and its interior is a planar region. Sometimes an arbitrary edge is chosen to be the ''base'', in which case the opposite vertex is called the ''apex''; the shortest segment between the base and apex is the ''height''. The area of a triangle equals one-half the product of height and base length. In Euclidean geometry, any two points determine a unique line segment situated within a unique straight line, and any three points that do not all lie on the same straight line determine a unique triangle situated w ...

Perspiration
Perspiration, also known as sweat, is the fluid secreted by sweat glands in the skin of mammals. Two types of sweat glands can be found in humans: eccrine glands and Apocrine sweat gland, apocrine glands. The eccrine sweat glands are distributed over much of the body and are responsible for secreting the watery, brackish sweat most often triggered by excessive body temperature. Apocrine sweat glands are restricted to the armpits and a few other areas of the body and produce an odorless, oily, opaque secretion which then gains its characteristic odor from bacterial decomposition. In humans, sweating is primarily a means of thermoregulation, which is achieved by the water-rich secretion of the eccrine glands. Maximum sweat rates of an adult can be up to per hour or per day, but is less in children prior to puberty. Evaporation of sweat from the skin surface has a cooling effect due to evaporative cooling. Hence, in Temperature, hot weather, or when the individual's muscles hea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heart Rate
Heart rate is the frequency of the cardiac cycle, heartbeat measured by the number of contractions of the heart per minute (''beats per minute'', or bpm). The heart rate varies according to the body's Human body, physical needs, including the need to absorb oxygen and excrete carbon dioxide. It is also modulated by numerous factors, including (but not limited to) genetics, physical fitness, Psychological stress, stress or psychological status, diet, drugs, hormonal status, environment, and disease/illness, as well as the interaction between these factors. It is usually equal or close to the pulse rate measured at any peripheral point. The American Heart Association states the normal resting adult human heart rate is 60–100 bpm. An ultra-trained athlete would have a resting heart rate of 37–38 bpm. ''Tachycardia'' is a high heart rate, defined as above 100 bpm at rest. ''Bradycardia'' is a low heart rate, defined as below 60 bpm at rest. When a human sleeps, a heartbeat with ra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
House Work
Homemaking is mainly an American and Canadian term for the management of a home, otherwise known as housework, housekeeping, housewifery or household management. It is the act of overseeing the organizational, day-to-day operations of a house or estate, and the managing of other domestic concerns. A person in charge of the homemaking, who is not employed outside the home, in the US and Canada, is called a homemaker, a term for a housewife or a stay-at-home dad. Historically, the role of homemaker was often assumed by women. The term "homemaker", however, may also refer to a social worker who manages a household during the incapacity of the housewife or househusband. Home health workers assume the role of homemakers when caring for elderly individuals. This includes preparing meals, giving baths, and any duties the person in need cannot perform for themselves. Homemaking can be the full-time responsibility of one spouse, partner, or parent, shared with children or extended fami ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strolling
Strolling is walking along or through at a leisurely pace. Strolling is a pastime and activity enjoyed worldwide as a leisure activity. The object of strolling is to walk at a slightly slower pace in an attempt to absorb the surroundings. Works featuring the ''flâneur'', French for a “strolling urban observer”, have appeared in European and American literature since the late 18th century. Etymology The verb form of "stroll" may have originated from a c.1600 Cant (language), Cant word. This word may have been derived from the German word ''strollen'', which in itself is a derivative of the German word ''strolchen'', which means "to roam, travel about aimlessly, drift, rove." The German noun ''strolch'' refers to any sort of vagabond or rogue. Before the American Revolution, a stroller was the British word for a vagabond. The noun stroll came from the verb in 1814. The term "stroller" was coined in the 1920s as a "child’s push-chair". The modern-day usage of the word ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Department Of Health And Human Services
The United States Department of Health and Human Services (HHS) is a cabinet-level executive branch department of the US federal government created to protect the health of the US people and providing essential human services. Its motto is "Improving the health, safety, and well-being of America". Before the separate federal Department of Education was created in 1979, it was called the Department of Health, Education, and Welfare (HEW). HHS is administered by the secretary of health and human services, who is appointed by the president with the advice and consent of the United States Senate. The United States Public Health Service Commissioned Corps, the uniformed service of the PHS, is led by the surgeon general who is responsible for addressing matters concerning public health as authorized by the secretary or by the assistant secretary for health in addition to his or her primary mission of administering the Commissioned Corps.

Physical Activity Guidelines For Americans
Physical Activity Guidelines for Americans are National Physical Activity Guidelines first published by the United States Department of Health and Human Services (HHS) in 2008. These guidelines provided physical activity recommendations for people aged six years and older, including those with many chronic health conditions and disabilities. The science-based Guidelines recommend a total amount of physical activity per week to achieve a range of health benefits. In 2018, HHS released an update to the first set of guidelines. This 2018 edition provides guidelines for people aged three years and older and summarizes the new knowledge gained from studies that were conducted since the first edition was released in 2008. These Guidelines can be tailored to meet individual interests, lifestyles, and goals. Recommendations in the Guidelines can be incorporated within daily routines and allow activities—like walking, biking, or dancing—to be integrated. The main message is that regula ...

Myokine
A myokine is one of several hundred cytokines or other small proteins (~5–20 kDa) and proteoglycan peptides that are produced and released by skeletal muscle cells (muscle fibers) in response to muscular contractions. They have autocrine, paracrine and/or endocrine effects; their systemic effects occur at picomolar concentrations. Receptors for myokines are found on muscle, fat, liver, pancreas, bone, heart, immune, and brain cells. The location of these receptors reflects the fact that myokines have multiple functions. Foremost, they are involved in exercise-associated metabolic changes, as well as in the metabolic changes following training adaptation. They also participate in tissue regeneration and repair, maintenance of healthy bodily functioning, immunomodulation; and cell signaling, expression and differentiation. History The definition and use of the term myokine first occurred in 2003. In 2008, the first myokine, myostatin, was identified. The gp130 receptor cytok ...

Endocrine Organ
The endocrine system is a messenger system in an organism comprising feedback loops of hormones that are released by internal glands directly into the circulatory system and that target and regulate distant organs. In vertebrates, the hypothalamus is the neural control center for all endocrine systems. In humans, the major endocrine glands are the thyroid, parathyroid, pituitary, pineal, and adrenal glands, and the (male) testis and (female) ovaries. The hypothalamus, pancreas, and thymus also function as endocrine glands, among other functions. (The hypothalamus and pituitary glands are organs of the neuroendocrine system. One of the most important functions of the hypothalamusit is located in the brain adjacent to the pituitary glandis to link the endocrine system to the nervous system via the pituitary gland.) Other organs, such as the kidneys, also have roles within the endocrine system by secreting certain hormones. The study of the endocrine system and its disorders is kn ...

Lifestyle (sociology)
Lifestyle is the interests, opinions, behaviours, and behavioural orientations of an individual, group, or culture. The term " style of life" () was introduced by Austrian psychologist Alfred Adler in his 1929 book, ''The Case of Miss R.'', with the meaning of "a person's basic character as established early in childhood". The broader sense of lifestyle as a "way or style of living" has been documented since 1961. Lifestyle is a combination of determining intangible or tangible factors. Tangible factors relate specifically to demographic variables, i.e. an individual's demographic profile, whereas intangible factors concern the psychological aspects of an individual such as personal values, preferences, and outlooks. A rural environment has different lifestyles compared to an urban metropolis. Location is important even within an urban scope. The nature of the neighborhood in which a person resides affects the set of lifestyles available to that person due to differences ...

Chronic Condition
A chronic condition (also known as chronic disease or chronic illness) is a health condition or disease that is persistent or otherwise long-lasting in its effects or a disease that comes with time. The term ''chronic'' is often applied when the course of the disease lasts for more than three months. Common chronic diseases include diabetes, functional gastrointestinal disorder, eczema, arthritis, asthma, chronic obstructive pulmonary disease, autoimmune diseases, genetic disorders and some viral diseases such as hepatitis C and acquired immunodeficiency syndrome. An illness which is lifelong because it ends in death is a terminal illness. It is possible and not unexpected for an illness to change in definition from terminal to chronic as medicine progresses. Diabetes and HIV for example were once terminal yet are now considered chronic, due to the availability of insulin for diabetics and daily drug treatment for individuals with HIV, which allow these individuals to live wh ...
