Long Distance Running
Long-distance running, or endurance running, is a form of continuous running over distances of at least . Physiologically, it is largely aerobic in nature and requires stamina as well as mental strength. Within endurance running comes two different types of respiration. The more prominent side that runners experience more frequently is aerobic respiration. This occurs when oxygen is present, and the body is able to utilize oxygen to help generate energy and muscle activity. On the other side, anaerobic respiration occurs when the body is deprived of oxygen, and this is common towards the final stretch of races when there is a drive to speed up to a greater intensity. Overall, both types of respiration are used by endurance runners quite often, but are very different from each other. Among mammals, humans are well adapted for running significant distances, and particularly so among primates. The capacity for endurance running is also found in migratory ungulates and a ...

Military Education And Training
Military education and training is a process which intends to establish and improve the capabilities of military personnel in their respective roles. Military training may be voluntary or compulsory duty. It begins with recruit training, proceeds to education and training specific to military roles, and sometimes includes additional training during a military career. Directing staff are the military personnel who comprise the instructional staff at a military training institution. In some countries, military education and training are parts of the compulsory education. The organizers believe that military education can bring some benefits and experiences that cannot be obtained from normal class like setback education. Moreover, participants are able to learn more survival skills during the military education, like co-operations and resilience, which will help participants improve the capabilities of military personnel in their respective roles.

Australian Aborigines
Aboriginal Australians are the various Indigenous peoples of the Australian mainland and many of its islands, such as Tasmania, Fraser Island, Hinchinbrook Island, the Tiwi Islands, and Groote Eylandt, but excluding the Torres Strait Islands. The term Indigenous Australians refers to Aboriginal Australians and Torres Strait Islanders collectively. It is generally used when both groups are included in the topic being addressed. Torres Strait Islanders are ethnically and culturally distinct, despite extensive cultural exchange with some of the Aboriginal groups. The Torres Strait Islands are mostly part of Queensland but have a separate governmental status. Aboriginal Australians comprise many distinct peoples who have developed across Australia for over 50,000 years. These peoples have a broadly shared, though complex, genetic history, but only in the last 200 years have they been defined and started to self-identify as a single group. Australian Aboriginal identity has c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Native Americans (Americas)
The Indigenous peoples of the Americas are the inhabitants of the Americas before the arrival of the European settlers in the 15th century, and the ethnic groups who now identify themselves with those peoples. Many Indigenous peoples of the Americas were traditionally hunter-gatherers and many, especially in the Amazon basin, still are, but many groups practiced aquaculture and agriculture. While some societies depended heavily on agriculture, others practiced a mix of farming, hunting, and gathering. In some regions, the Indigenous peoples created monumental architecture, large-scale organized cities, city-states, chiefdoms, states, kingdoms, republics, confederacies, and empires. Some had varying degrees of knowledge of engineering, architecture, mathematics, astronomy, writing, physics, medicine, planting and irrigation, geology, mining, metallurgy, sculpture, and gold smithing. Many parts of the Americas are still populated by Indigenous peoples; some countries have size ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kalahari Desert
The Kalahari Desert is a large semi-arid sandy savanna in Southern Africa extending for , covering much of Botswana, and parts of Namibia and South Africa. It is not to be confused with the Angolan, Namibian, and South African Namib coastal desert, whose name is of Khoekhoegowab origin and means "vast place". Etymology ''Kalahari'' is derived from the Tswana word ''Kgala'', meaning "the great thirst", or ''Kgalagadi'', meaning "a waterless place"; the Kalahari has vast areas covered by red sand without any permanent surface water. History The Kalahari Desert was not always a dry desert. The fossil flora and fauna from Gcwihaba Cave in Botswana indicates that the region was much wetter and cooler at least from 30 to 11 thousand BP (before present) especially after 17,500 BP. Geography Drainage of the desert is by dry black valleys, seasonally inundated pans and the large salt pans of the Makgadikgadi Pan in Botswana and Etosha Pan in Namibia. The only permanent riv ...

San People
The San peoples (also Saan), or Bushmen, are members of various Khoe, Tuu, or Kxʼa-speaking indigenous hunter-gatherer cultures that are the first cultures of Southern Africa, and whose territories span Botswana, Namibia, Angola, Zambia, Zimbabwe, Lesotho and South Africa. In 2017, Botswana was home to approximately 63,500 San people (roughly 2.8% of the population) making it the country with the highest number of San people. Definition The term "San" has a long vowel and is spelled Sān (in Khoekhoegowab orthography). It is a Khoekhoe exonym with the meaning of "foragers" and was often used in a derogatory manner to describe nomadic, foraging people. Based on observation of lifestyle, this term has been applied to speakers of three distinct language families living between the Okavango River in Botswana and Etosha National Park in northwestern Namibia, extending up into southern Angola; central peoples of most of Namibia and Botswana, extending into Zambia an ...

Hunter-gatherer
A traditional hunter-gatherer or forager is a human living an ancestrally derived lifestyle in which most or all food is obtained by foraging, that is, by gathering food from local sources, especially edible wild plants but also insects, fungi, honey, or anything safe to eat, and/or by hunting game (pursuing and/or trapping and killing wild animals, including catching fish), roughly as most animal omnivores do. Hunter-gatherer societies stand in contrast to the more sedentary agricultural societies, which rely mainly on cultivating crops and raising domesticated animals for food production, although the boundaries between the two ways of living are not completely distinct. Hunting and gathering was humanity's original and most enduring successful competitive adaptation in the natural world, occupying at least 90 percent of human history. Following the invention of agriculture, hunter-gatherers who did not change were displaced or conquered by farming or pastoralist ...

Anthropology
Anthropology is the scientific study of humanity, concerned with human behavior, human biology, cultures, societies, and linguistics, in both the present and past, including past human species. Social anthropology studies patterns of behavior, while cultural anthropology studies cultural meaning, including norms and values. A portmanteau term sociocultural anthropology is commonly used today. Linguistic anthropology studies how language influences social life. Biological or physical anthropology studies the biological development of humans. Archaeological anthropology, often termed as 'anthropology of the past', studies human activity through investigation of physical evidence. It is considered a branch of anthropology in North America and Asia, while in Europe archaeology is viewed as a discipline in its own right or grouped under other related disciplines, such as history and palaeontology. Etymology The abstract noun '' anthropology'' is first attested in refe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
All-weather Track
An all-weather running track is a rubberized, artificial running surface for track and field athletics. It provides a consistent surface for competitors to test their athletic ability unencumbered by adverse weather conditions. Historically, various forms of dirt, Rocks, sand, and crushed cinders were used. Many examples of these varieties of track still exist worldwide. Surfaces Starting in the late 1950s, artificial surfaces using a combination of rubber and asphalt began to appear. An artificial warm-up track was constructed for the 1956 Summer Olympics in Melbourne, Australia. During the 1960s many of these tracks were constructed; examples still exist today. In the mid-1960s Tartan tracks were developed, surfaced with a product by 3M. The name ''Tartan'' is a trademark, but it is sometimes used as a genericized trademark. This process was the first to commercialize a polyurethane surface for running tracks, though it was originally conceived for horse racing. Man ...

Cross Country Running
Cross country running is a sport in which teams and individuals run a race on open-air courses over natural terrain such as dirt or grass. The course, typically long, may include surfaces of grass and earth, pass through woodlands and open country, and include hills, flat ground and sometimes gravel road and minor obstacles. It is both an individual and a team sport; runners are judged on individual times and teams by a points-scoring method. Both men and women of all ages compete in cross country, which usually takes place during autumn and winter, and can include weather conditions of rain, sleet, snow or hail, and a wide range of temperatures. Cross country running is one of the disciplines under the umbrella sport of athletics and is a natural-terrain version of long-distance track and road running. Although open-air running competitions are prehistoric, the rules and traditions of cross country racing emerged in Britain. The English championship became the first natio ...

Road Running
Road running is the sport of running on a measured course over an established road. This differs from track and field on a regular track and cross country running over natural terrain. These events are usually classified as long-distance according to athletics terminology, with races typically ranging from 5 kilometers to 42.2 kilometers in the marathon. They may involve large numbers of runners or wheelchair entrants. The four most common IAAF recognized distances for road running events are 5K runs, 10K runs, half marathons and marathons. Running on the road is an alternative surface to running on a trail, track, or treadmill. For many people looking to participate in running as an activity or sport, there are multiple opportunities that can be found on the road. Road running is one of several forms of road racing, which also includes road bicycle racing and motor vehicle road racing. IAAF The international governing body for road racing is the IAAF.

Track Running
Track and field is a sport that includes athletic contests based on running, jumping, and throwing skills. The name is derived from where the sport takes place, a running track and a grass field for the throwing and some of the jumping events. Track and field is categorized under the umbrella sport of athletics, which also includes road running, cross country running and racewalking. The foot racing events, which include sprints, middle- and long-distance events, racewalking, and hurdling, are won by the athlete who completes it in the least time. The jumping and throwing events are won by those who achieve the greatest distance or height. Regular jumping events include long jump, triple jump, high jump, and pole vault, while the most common throwing events are shot put, javelin, discus, and hammer. There are also "combined events" or "multi events", such as the pentathlon consisting of five events, heptathlon consisting of seven events, and decathlon consisting of ten eve ...
