Waterskiing
Water skiing (also waterskiing or water-skiing) is a surface water sport in which an individual is pulled behind a boat or a cable ski installation over a body of water, skimming the surface on one or two skis. The sport requires sufficient area on a stretch of water, one or two skis, a tow boat with tow rope, two or three people (depending on local boating laws), and a personal flotation device. In addition, the skier must have adequate upper and lower body strength, muscular endurance, and good balance. There are water ski participants around the world, in Asia and Australia, Europe, Africa, and the Americas. In the United States alone, there are approximately 11 million water skiers and over 900 sanctioned water ski competitions every year. Australia boasts 1.3 million water skiers. There are many options for recreational or competitive water skiers. These include speed skiing, trick skiing, show skiing, slaloming, jumping, barefoot skiing and wakeski. Similar, related ...

Yarra River
The Yarra River or historically, the Yarra Yarra River, (Kulin languages: ''Berrern'', ''Birr-arrung'', ''Bay-ray-rung'', ''Birarang'', ''Birrarung'', and ''Wongete'') is a perennial river in south-central Victoria, Australia. The lower stretches of the Yarra are where Victoria's state capital Melbourne was established in 1835, and today metropolitan Greater Melbourne dominates and influences the landscape of its lower reaches. From its source in the Yarra Ranges, it flows west through the Yarra Valley which opens out into plains as it winds its way through Greater Melbourne before emptying into Hobsons Bay in northernmost Port Phillip Bay. The river has been a major food source and meeting place for Indigenous Australians for thousands of years. Shortly after the arrival of European settlers, land clearing forced the remaining Wurundjeri people into neighbouring territories and away from the river. Originally called ''Birrarung'' by the Wurundjeri, the current name w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water Skier Rising Out Of Water
Water is an inorganic compound with the chemical formula . It is a transparent, tasteless, odorless, and Color of water, nearly colorless chemical substance. It is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent). It is vital for all known forms of life, despite not providing food energy or organic micronutrients. Its chemical formula, , indicates that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. The hydrogen atoms are attached to the oxygen atom at an angle of 104.45°. In liquid form, is also called "water" at standard temperature and pressure. Because Earth's environment is relatively close to water's triple point, water exists on Earth as a solid, a liquid, and a gas. It forms precipitation in the form of rain and aerosols in the form of fog. Clouds consist of suspended droplets of water and ice, its solid state. When finely divided, crystalline ice ...

Surface Water Sports
The following is a list of surface water sports. These are sports which are performed atop a body of water. Boat racing Motorized racing * Hydroplane racing * Bathtub racing Rowing * Canoeing * Kayaking * Sweep rowing * Sculling * Dragon boat racing Sailing * Yacht racing * Hydrofoil sailing. This recent development in the high-speed sailing arena has evolved most in the International Moth class of racing dinghy. These boats have a T-shaped rudder and centreboard that generates sufficient lift to clear the hull from the water. When this happens wetted surface area drops radically and the boats accelerate up to 1.2 to 1.5 times the speed of the prevailing wind. These boats are very light (all up weight is less than 40 kg) and very fast, They hydrofoil in as little as of breeze ("sit on the deck breeze" for most dinghy classes). The top recorded speed is about 50 km/hour, and speeds of 40 km/hour are common in the class. All types of propulsion * Dinghy racin ...

Cable Skiing
Cable skiing is a way to water ski (or wakeboard), in which the skier's rope and handle are pulled by an electrically driven cable, whereas traditionally a waterskier is pulled by a motorboat. The mechanism consists of two cables running parallel to one another with carriers between them every 80 metres. The carriers are metal tubes that can hook up tow ropes with riders. Tow ropes are detached and attached at the same time without slowing the system down, which is a main reason for its high efficiency. With a main cable of 800 metres long, 10 riders can waterski or wakeboard at the same time. The speed of the main cable can be up to , and slalom skiers can reach much higher speeds. The most common speed is , which suits wakeboarders best. The cable is generally suspended above the water. This makes for a different feel than when riding behind a boat, whether wakeboarding or water skiing. The higher angle of pull makes bigger "air" and sharper turns possible. Generally, on wa ...

Competitive
Competition is a rivalry where two or more parties strive for a common goal which cannot be shared: where one's gain is the other's loss (an example of which is a zero-sum game). Competition can arise between entities such as organisms, individuals, economic and social groups, etc. The rivalry can be over attainment of any exclusive goal, including recognition. Competition occurs in nature, between living organisms which co-exist in the same environment. Animals compete over water supplies, food, mates, and other biological resources. Humans usually compete for food and mates, though when these needs are met deep rivalries often arise over the pursuit of wealth, power, prestige, and fame when in a static, repetitive, or unchanging environment. Competition is a major tenet of market economies and business, often associated with business competition as companies are in competition with at least one other firm over the same group of customers. Competition inside a company ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Safety Measures
Safety is the state of being protected from harm or other danger. Safety can also refer to the control of recognized hazards in order to achieve an acceptable level of risk. Meanings The word 'safety' entered the English language in the 14th century. It is derived from Latin , meaning uninjured, in good health, safe. There are two slightly different meanings of "safety". For example, "home safety" may indicate a building's ability to protect against external harm events (such as weather, home invasion, etc.), or may indicate that its internal installations (such as appliances, stairs, etc.) are safe (not dangerous or harmful) for its inhabitants. Discussions of safety often include mention of related terms. Security is such a term. With time the definitions between these two have often become interchanged, equated, and frequently appear juxtaposed in the same sentence. Readers are left to conclude whether they comprise a redundancy. This confuses the uniqueness that shoul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Muscle Strength
Skeletal muscle (commonly referred to as muscle) is one of the three types of vertebrate muscle tissue, the others being cardiac muscle and smooth muscle. They are part of the somatic nervous system, voluntary muscular system and typically are attached by tendons to bones of a skeleton. The skeletal muscle cells are much longer than in the other types of muscle tissue, and are also known as ''muscle fibers''. The tissue of a skeletal muscle is striated muscle tissue, striated – having a striped appearance due to the arrangement of the sarcomeres. A skeletal muscle contains multiple muscle fascicle, fascicles – bundles of muscle fibers. Each individual fiber and each muscle is surrounded by a type of connective tissue layer of fascia. Muscle fibers are formed from the cell fusion, fusion of developmental myoblasts in a process known as myogenesis resulting in long multinucleated cells. In these cells, the cell nucleus, nuclei, termed ''myonuclei'', are located along the inside ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
