Physical activity is defined as any voluntary bodily movement produced by skeletal muscles that requires energy expenditure. Physical activity encompasses all activities, at any intensity, performed during any time of day or night. It includes both voluntary exercise and incidental activity integrated into the daily routine. This integrated activity may not be planned, structured, repetitive or purposeful for the improvement of physical fitness , and may include activities such as walking to the local shop, cleaning, working, active transport etc. Lack of physical activity is associated with a range of negative health outcomes, whereas increased physical activity can improve physical and mental health, as well as cognitive and cardiovascular health. There are at least eight investments that work to increase population-level physical activity, including whole-of-school programmes, active transport, active urban design, healthcare, public education and mass media, sport for all, workplaces and community-wide programmes. Physical activity increases energy expenditure and is a key regulator in controlling body weight (see Summermatter cycle for more). In human beings, differences among individuals in the amount of physical activity have a substantial genetic basis.

The popularity of spectator sport as a recreation for non-participants has led to sport becoming a major business in its own right, and this has incentivised a high paying professional sport culture, where high performing participants are rewarded with pay far in excess of average wages, which can run into millions of dollars. Some sports, or individual competitions within

The technology is not compulsory, but was used in the 2014 FIFA World Cup in Brazil, and the 2015 FIFA Women's World Cup in Canada, as well as in the Premier League from 2013–14 , and the Bundesliga from 2015–16 . In the NFL , a referee can ask for a review from the replay booth, or a head coach can issue a challenge to review the play using replays. The final decision rests with

These separate forms of meaningfulness consist of (i) competition and championship, (ii) nature encounters, (iii) aesthetic-expressive, (iv) fitness gymnastics and play, (v) everyday exercise and (vi) five different basic forms of physical training (aerobic, anaerobic, strength, flexibility and coordination training). How these different clusters have been treated over time from 1813 to today in

402-522: A context of teacher training for physical education in the Swedish school system has been described by the Swedish professors in human movement science Suzanne Lundvall & Peter Schantz (2013). The World Health Organization recommend the following: 1. Adults aged 18–64 should do at least 150 minutes of moderate-intensity aerobic physical activity throughout the week or do at least 75 minutes of vigorous-intensity aerobic physical activity throughout

603-496: A large population-based study in England, higher air temperatures and lower wind speeds were associated with increased physical activity. Globally, in 2016, according to a pooled analysis of 298 population-based surveys, around 81% of students aged 11–17 years were insufficiently physically active. The region with the highest prevalence of insufficient activity in 2016 was high-income Asia Pacific. Physical activity, qualified in

670-460: A multitude of reasons. A 2021 study shows that people who start successful physical activity programmes maintain much of it for at least three months. Physical activity can be at any intensity, ranging from a little muscle twitch to a full-out sprint. Physical activity can be thought of as a continuum in practice, ranging from inactive lifestyles to high-intensity exercises. Intensities are broadly categorized according to energy expenditure using

737-769: A small number of mind sports, it is not open to admitting any further mind sports. There has been an increase in the application of the term "sport" to a wider set of non-physical challenges such as video games , also called esports (from "electronic sports"), especially due to the large scale of participation and organised competition, but these are not widely recognised by mainstream sports organisations. According to Council of Europe , European Sports Charter, article 2.i, " 'Sport' means all forms of physical activity which, through casual or organised participation, aim at expressing or improving physical fitness and mental well-being, forming social relationships or obtaining results in competition at all levels."

Adults aged 65 years and above should do at least 150 minutes of moderate-intensity aerobic physical activity throughout the week or do at least 75 minutes of vigorous-intensity aerobic physical activity throughout the week or an equivalent combination of moderate- and vigorous-intensity activity. 2. Aerobic activity should be performed in bouts of at least 10 minutes duration. 3. For additional health benefits, adults aged 65 years and above should increase their moderate-intensity aerobic physical activity to 300 minutes per week, or engage in 150 minutes of vigorous-intensity aerobic physical activity per week, or an equivalent combination of moderate-and vigorous-intensity activity. 4. Adults of this age group, with poor mobility, should perform physical activity to enhance balance and prevent falls on 3 or more days per week. 5. Muscle-strengthening activities should be done involving major muscle groups, on 2 or more days

Children and youth aged 5–17 should accumulate at least 60 minutes of moderate- to vigorous-intensity physical activity daily. 2. Amounts of physical activity greater than 60 minutes provide additional health benefits. Australia, New Zealand,

1139-555: Is running , while association football is the most popular spectator sport. The word "sport" comes from the Old French desport meaning " leisure ", with the oldest definition in English from around 1300 being "anything humans find amusing or entertaining".

1206-638: Is a cornerstone of public health and prevention of non-communicable disease . Physical inactivity has been found to cause a wide range of non-communicable diseases, including coronary heart disease, stroke, diabetes mellitus and depression. An analysis of the healthcare costs of non-communicable diseases and mental illness attributable to physical inactivity for 2020–30 found that 500 million new cases of disease will occur globally between 2020 and 2030 if physical activity remains at today's levels. This corresponds to more than US$ 300 billion in treatment costs As of 2024, 31% of adults and 80% of adolescents do not meet

The inclusion of mind sports within sport definitions has not been universally accepted, leading to legal challenges from governing bodies in regards to being denied funding available to sports. Whilst GAISF recognises

The well-known sentiment by sports journalist Grantland Rice , that it is "not that you won or lost but how you played the game", and the modern Olympic creed expressed by its founder Pierre de Coubertin : "The most important thing... is not winning but taking part" are typical expressions of this sentiment. Key principles of sport include that the result should not be predetermined, and that both sides should have equal opportunity to win. Rules are in place to ensure fair play, but participants can break these rules in order to gain advantage. Participants may cheat in order to unfairly increase their chance of winning, or in order to achieve other advantages such as financial gains. The widespread existence of gambling on

3484-599: The necessity of competition as a defining element of a sport, with almost all professional sports involving competition, and governing bodies requiring competition as a prerequisite of recognition by the International Olympic Committee (IOC) or GAISF. Other bodies advocate widening the definition of sport to include all physical activity. For instance, the Council of Europe include all forms of physical exercise, including those competed just for fun. In order to widen participation, and reduce

3551-470: The noun sport as an "activity engaged in for relaxation and amusement" with synonyms including diversion and recreation.

American English uses "sports" for both terms. The precise definition of what differentiates

3618-581: The number of mind games which can be admitted as sports. Sport is usually governed by a set of rules or customs , which serve to ensure fair competition. Winning can be determined by physical events such as scoring goals or crossing a line first. It can also be determined by judges who are scoring elements of the sporting performance, including objective or subjective measures such as technical performance or artistic impression. Records of performance are often kept, and for popular sports, this information may be widely announced or reported in sport news . Sport

Demographic groups can also intersect, increasing risk to individuals who are both female and socially disadvantaged for example. Studies have shown that as availability of natural environments (e.g., parks, woodlands, inland waters, coasts) increases, more leisure-time physical activity such as walking and cycling are reported. Meteorological conditions have been found to predict physical activity differently in different types of environment. For example, in
