Effects Of Weather On Sport
The effects of weather on sport are varied, with some events unable to take place while others are changed considerably. The performance of participants can be reduced or improved, and some sporting world records are invalid if set under certain weather conditions. While outdoor sports are most affected, those played indoors can still be impacted by adverse or advantageous weather conditions. Temperature Temperature has a significant impact on the performance of athletes. High temperature can cause various heat illnesses such as heat cramps and heatstroke, while very low temperatures may lead to hypothermia. In cross country skiing world cup, races are cancelled or postponed if the temperature in a major portion of the course is -25°C or lower, while in biathlon the limit is -20°C. Training regimes may include methods of heat acclimatization, and regulations in some sports stipulate the intensity of some schedules.

Auto Racing
Auto racing (also known as car racing, motor racing, or automobile racing) is a motorsport involving the racing of automobiles for competition. In North America, the term is commonly used to describe all forms of automobile sport including non-racing disciplines. Auto racing has existed since the invention of the automobile. Races of various types were organized, with the first recorded as early as 1867. Many of the earliest events were effectively Classic trials, reliability trials, aimed at proving these new machines were a practical mode of transport, but soon became an important way for automobile makers to demonstrate their machines. By the 1930s, specialist racing cars had developed. There are now numerous different categories, each with different rules and regulations. History The first prearranged match race of two self-powered road vehicles over a prescribed route occurred at 4:30 A.M. on August 30, 1867, between Ashton-under-Lyne and Old Trafford, England, a di ...

Wind Assistance
In track and field, wind assistance is the benefit that an athlete receives during a race or event as registered by a wind gauge. Wind is one of many forms of weather that can affect sport. Due to a tailwind helping to enhance the speed of the athlete in events like certain sprint races ( 100 and 200 metres), 100/110 metres hurdles, the triple jump and the long jump, there is a limit to how much wind assistance the athlete may compete under if the performance is to establish a record. If a tail wind exceeds the result cannot be registered as a record on any level. However, the results within that competition are still valid because all athletes in said race would receive similar assistance, and in field events it is just random circumstance at the moment of the attempt. The wind assistance maximums are only in regard to the validation of a record. The exceptions are the combined events like heptathlon and decathlon. Here, the total score may be accepted even though some of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Golf
Golf is a club-and-ball sport in which players use various Golf club, clubs to hit a Golf ball, ball into a series of holes on a golf course, course in as few strokes as possible. Golf, unlike most ball games, cannot and does not use a standardized playing area, and coping with the varied terrains encountered on different courses is a key part of the game. Courses typically have either 9 or 18 Glossary of golf#Hole, ''holes'', regions of terrain that each contain a ''cup'', the hole that receives the ball. Each hole on a course has a teeing ground for the hole's first stroke, and a putting green containing the cup. There are several standard forms of terrain between the tee and the green, such as the fairway, rough (tall grass), and various Hazard (golf), ''hazards'' that may be water, rocks, or sand-filled Glossary of golf#Bunker, ''bunkers''. Each hole on a course is unique in its specific layout. Many golf courses are designed to resemble their native landscape, such as alon ...

Wind
Wind is the natural movement of atmosphere of Earth, air or other gases relative to a planetary surface, planet's surface. Winds occur on a range of scales, from thunderstorm flows lasting tens of minutes, to local breezes generated by heating of land surfaces and lasting a few hours, to global winds resulting from the difference in absorption (electromagnetic radiation), absorption of solar energy between the climate zones on Earth. The study of wind is called anemology. The two main causes of large-scale atmospheric circulation are the differential heating between the equator and the poles, and the rotation of the planet (Coriolis effect). Within the tropics and subtropics, thermal low circulations over terrain and high plateaus can drive monsoon circulations. In coastal areas the sea breeze/land breeze cycle can define local winds; in areas that have variable terrain, mountain and valley breezes can prevail. Winds are commonly classified by their scale (spatial), spatial ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waterlogging (agriculture)
Waterlogging water is the saturation of soil with water. Soil may be regarded as waterlogged when it is nearly saturated with water much of the time such that its air phase is restricted and Hypoxia (environmental), anaerobic conditions prevail. In extreme cases of prolonged waterlogging, anaerobiosis occurs, the roots of mesophytes suffer, and the subsurface reducing atmosphere leads to such processes as denitrification, methanogenesis, and the reduction of iron and manganese oxides. All plants, including crop, require Earth's atmosphere, air (specifically, oxygen) to respire, produce energy, and keep their cells alive. In agriculture, waterlogging typically blocks air from getting to the roots. With the exception of rice (''Oryza sativa''), most crops like maize and potato, are therefore highly intolerant to waterlogging. Plant Cell (biology), cells use a variety of signals such the oxygen concentration, plant hormones like ethylene, energy and sugar status to acclimate to ...

Tennis
Tennis is a List of racket sports, racket sport that is played either individually against a single opponent (singles (tennis), singles) or between two teams of two players each (doubles (tennis), doubles). Each player uses a tennis racket strung with a cord to strike a hollow rubber tennis ball, ball covered with felt over or around a net and into the opponent's tennis court, court. The object is to manoeuvre the ball in such a way that the opponent is not able to play a valid return. If a player is unable to return the ball successfully, the opponent scores a Point (tennis), point. Playable at all levels of society and at all ages, tennis can be played by anyone who can hold a racket, including Wheelchair tennis, wheelchair users. The original forms of tennis developed in France during the late Middle Ages. The modern form of tennis originated in Birmingham, England, in the late 19th century as lawn tennis. It had close connections to various field (lawn) games such as croqu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
