Plyometrics
Plyometrics, also known as jump training or plyos, are exercises in which muscles exert maximum force in short intervals of time, with the goal of increasing power (speed-strength). This training focuses on learning to move from a muscle extension to a contraction in a rapid or "explosive" manner, such as in specialized repeated jumping. Plyometrics are primarily used by athletes, especially martial artists, sprinters and high jumpers, to improve performance, and are used in the fitness field to a much lesser degree. Overview Plyometrics include explosive exercises to activate the quick response and elastic properties of the major muscles. It was initially adopted by Soviet Olympians in the 1950s, and then by sportspeople worldwide. Sports using plyometrics include basketball, tennis, badminton, squash and volleyball as well as the various codes of football. The term "plyometrics" was coined by Fred Wilt after watching Soviet athletes prepare for their events in track and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Push-up
The push-up (press-up in British English) is a common calisthenics Physical exercise, exercise beginning from the prone position. By raising and lowering the body using the arms, push-ups exercise the pectoralis major muscle, pectoral muscles, triceps, and anterior deltoid muscle, deltoids, with ancillary benefits to the rest of the deltoids, serratus anterior muscle, serratus anterior, coracobrachialis muscle, coracobrachialis and the midsection as a whole. Push-ups are a basic exercise used in civilian athletic training or physical education and commonly in Military Fitness, military physical training. It is also a common form of punishment used in the military, school sport, and some martial arts disciplines for its humiliating factor (when one fails to do a specified amount) and for its lack of equipment. Variations of push-ups, such as wide-arm push-ups, diamond push-ups target specific muscle groups and provide further challenges. Etymology The American English term '' ...

US Olympic
The United States of America has sent athletes to every celebration of the modern Olympic Games with the exception of the 1980 Summer Olympics, during which it led a boycott in protest of the Soviet Union's invasion of Afghanistan. The United States Olympic & Paralympic Committee (USOPC) is the National Olympic Committee for the United States. American athletes have won a total of 2,765 medals (1,105 of them gold) at the Summer Olympic Games, and another 330 (114 of them gold) at the Winter Olympic Games, making the United States the most prolific medal-winning nation in the history of the Olympics. The U.S. has placed first in the Summer Olympic medal table 19 times out of 30 Summer Olympics and 29 appearances (having boycotted in 1980), but has had less success in the Winter Olympics, placing first once in 24 participations. The United States Olympic contingent is the only Olympic contingent in the world to receive no government funding; neither training and development co ...

Split Jump (exercise)
A split jump (also known as lunge jump, jumping lunge, plyometric lunge or simply plyo lunge. Not to be confused with the split jump used by dancers, gymnasts and figure skaters) is a form of exercise which focuses on the upper leg muscles, especially the quadriceps: #assume an upright squatting position with one foot forward and the other back #with a jumping motion, simultaneously move the rear foot forward and the front foot back, ending as position 1 with the feet reversed #repeat The exercise is often used for increasing lower body strength and overall athleticism.

Figure Skaters
Figure skating is a sport in which individuals, pairs, or groups perform on figure skates on ice. It was the first winter sport to be included in the Olympic Games, with its introduction occurring at the 1908 Olympics in London. The Olympic disciplines are men's singles, women's singles, pair skating, and ice dance; the four individual disciplines are also combined into a team event, which was first included in the Winter Olympics in 2014. The non-Olympic disciplines include synchronized skating, Theater on Ice, and four skating. From intermediate through senior-level competition, skaters generally perform two programs (the short program and the free skate), which, depending on the discipline, may include spins, jumps, moves in the field, lifts, throw jumps, death spirals, and other elements or moves. Figure skaters compete at various levels from beginner up to the Olympic level (senior) at local, regional, sectional, national, and international competitions. The Interna ...

Gymnasts
Gymnastics is a group of sport that includes physical exercises requiring balance, strength, flexibility, agility, coordination, artistry and endurance. The movements involved in gymnastics contribute to the development of the arms, legs, shoulders, back, chest, and abdominal muscle groups. Gymnastics evolved from exercises used by the ancient Greeks that included skills for mounting and dismounting a horse. The most common form of competitive gymnastics is artistic gymnastics (AG); for women, the events include floor, vault, uneven bars, and balance beam; for men, besides floor and vault, it includes rings, pommel horse, parallel bars, and horizontal bar. The governing body for competition in gymnastics throughout the world is the Fédération Internationale de Gymnastique (FIG). Eight sports are governed by the FIG, including gymnastics for all, men's and women's artistic gymnastics, rhythmic gymnastics (women's branch only), trampolining (including double mini-trampoline ...

Dancers
Dance is an art form, consisting of sequences of body movements with aesthetic and often symbolic value, either improvised or purposefully selected. Dance can be categorized and described by its choreography, by its repertoire of movements or by its historical period or place of origin. Dance is typically performed with musical accompaniment, and sometimes with the dancer simultaneously using a musical instrument themselves. Two common types of group dance are theatrical and participatory dance. Both types of dance may have special functions, whether social, ceremonial, competitive, erotic, martial, sacred or liturgical. Dance is not solely restricted to performance, as dance is used as a form of exercise and occasionally training for other sports and activities. Dance performances and dancing competitions are found across the world exhibiting various different styles and standards. Dance may also be participated in alone as a form of exercise or self expression. Dancing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Split Jumps
A split jump is a sequence of body movements in which a split is performed after jumping, while the performer is still in the air. Split jumps are commonly found in dance, figure skating, and gymnastics, and may also be used as a form of exercise. In figure skating Split jumps are a category of figure skating jumps in which the skater achieves a split position in the air. Unlike most figure skating jumps, split jumps are positional jumps, rather than rotational jumps; the point of them is to achieve a position in the air, not to rotate a specific number of times. Most split jumps are derived from the half flip, a half-rotation jump with a flip entry. Split jumps can also be done with half Lutz or falling leaf (a loop jump with a half-revolution in the air) entries. More rarely, full-rotation flip and Lutz jumps can be done with a split. These jumps are known as the ''split flip'' and ''split Lutz''. As an alternative to the standard front split, some skaters perform a ''Russ ...

Broad Jump
The long jump is a track and field event in which athletes combine speed, strength and agility in an attempt to leap as far as possible from a takeoff point. Along with the triple jump, the two events that measure jumping for distance as a group are referred to as the "horizontal jumps". This event has a history in the ancient Olympic Games and has been a modern Olympic event for men since the first Olympics in 1896 and for women since 1948. Rules At the elite level, competitors run down a runway (usually coated with the same rubberized surface as running tracks, crumb rubber or vulcanized rubber, known generally as an all-weather track) and jump as far as they can from a wooden or synthetic board, 20 centimetres or 8 inches wide, that is built flush with the runway, into a pit filled with soft damp sand. If the competitor starts the leap with any part of the foot past the foul line, the jump is declared a foul and no distance is recorded. To detect this occurrence ...

Jumping
Jumping or leaping is a form of locomotion or movement in which an organism or non-living (e.g., robotic) mechanical system propels itself through the air along a ballistic trajectory. Jumping can be distinguished from running, galloping and other gaits where the entire body is temporarily airborne by the relatively long duration of the aerial phase and high angle of initial launch. Some animals, such as the kangaroo, employ jumping (commonly called ''hopping'' in this instance) as their primary form of an locomotion, while others, such as frogs, use it only as a means to escape predators. Jumping is also a key feature of various activities and sports, including the long jump, high jump and show jumping. Physics All jumping involves the application of force against a substrate, which in turn generates a reactive force that propels the jumper away from the substrate. Any solid or liquid capable of producing an opposing force can serve as a substrate, including ground or wat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
