I-formation (tennis)
I-formation is a doubles tennis strategy carefully planned to confuse the opponent returning the serve. "The name comes from its resemblance to American football's I formation, in which the fullback positions right behind the halfback, who positions right behind the quarterback." "The net player on the serving team crouches down (so they do not get hit by the serve) on the centre service line. The server hits the serve from directly behind her on the baseline". The net player then indicates (privately), typically with their hands behind their back, which side of the court they will move to as the return of serve is hit. These hand gestures let the server at the baseline know which side of the court they are to serve to, and then move to. For intermediate players, such as league or club players, it is recommended that the server head to the opposite side to which the net player is headed so that maximum court coverage is obtained. Advanced competitors, such as professional and tour ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Serve (tennis)
A serve (or, more formally, a service) in tennis is a shot to start a point. A player will hit the ball with a racquet so it will fall into the diagonally opposite service box without being stopped by the net. Normally players begin a serve by tossing the ball into the air and hitting it (usually near the highest point of the toss). The ball can only touch the net on a return and will be considered good if it falls on the opposite side. If the ball contacts the net on the serve but then proceeds to the proper service box, it is called a ''let''; this is not a legal serve in the major tours (but see below) although it is also not a ''fault''. Players normally serve overhead; however serving underhand is allowed. The serve is the only shot a player can take their time to set up instead of having to react to an opponent's shot; however, as of 2012, there is a 25-second limit to be allowed between points. The serve is one of the most difficult shots for a novice, but once mastered it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
I Formation
The I formation is one of the most common offensive formations in American football. The I formation draws its name from the vertical (as viewed from the opposing endzone) alignment of quarterback, fullback, and running back, particularly when contrasted with the same players' alignments in the ''T formation''. The formation begins with the usual 5 offensive linemen (2 offensive tackles, 2 guards, and a center), the quarterback under center, and two backs in-line behind the quarterback. The base variant adds a tight end to one side of the line and two wide receivers, one at each end of the line. History The exact origin of the I formation is unclear. Charles M. Hollister of Northwestern in 1900 is one source, as is Bob Zuppke in 1914. Tom Nugent is credited with developing the I formation at Virginia Military Institute in 1950 as a replacement for the single-wing and an alternative to the T formation. Don Coryell, before popularizing Air Coryell, was also a pioneer o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fullback (gridiron Football)
A fullback (FB) is a position in the offensive backfield in gridiron football, and is one of the two running back positions along with the halfback. Fullbacks are typically larger than halfbacks and in most offensive schemes the fullback's duties are split among power running, pass catching, and blocking for both the quarterback and the other running back. Many great runners in the history of American football have been fullbacks, including Jim Brown, Marion Motley, Bronko Nagurski, Jim Taylor, Franco Harris, Larry Csonka, John Riggins, Christian Okoye, and Levi Jackson. However, many of these runners would retroactively be labeled as halfbacks, due to their position as the primary ball carrier; they were primarily listed as fullbacks due to their size and did not often perform the run-blocking duties expected of modern fullbacks. Examples of players who have excelled at the hybrid running–blocking–pass-catching role include Vonta Leach, Mike Alstott, William Henderson, ...

Halfback (American Football)
A halfback (HB) is an offensive position in American football, whose duties involve lining up in the offensive backfield and carrying the ball on most rushing plays, i.e. a running back. When the principal ball carrier lines up deep in the backfield, and especially when that player is placed behind another player (usually a blocking back), as in the I formation, that player is instead referred to as a tailback. Sometimes the halfback can catch the ball from the backfield on short passing plays as they are an eligible receiver. Occasionally, they line up as additional wide receivers. When not running or catching the ball, the primary responsibility of a halfback is to aid the offensive linemen in blocking, either to protect the quarterback or another player carrying the football. History Overview Before the emergence of the T formation in the 1940s, all members of the offensive backfield were legitimate threats to run or pass the ball. Most teams used four offensive back ...

Quarterback
The quarterback (commonly abbreviated "QB"), colloquially known as the "signal caller", is a position in gridiron football. Quarterbacks are members of the offensive platoon and mostly line up directly behind the offensive line. In modern American football, the quarterback is usually considered the leader of the offense, and is often responsible for calling the play in the huddle. The quarterback also touches the ball on almost every offensive play, and is almost always the offensive player that throws forward passes. When the QB is tackled behind the line of scrimmage, it is called a sack. Overview In modern American football, the starting quarterback is usually the leader of the offense, and their successes and failures can have a significant impact on the fortunes of their team. Accordingly, the quarterback is among the most glorified, scrutinized, and highest-paid positions in team sports. '' Bleacher Report'' describes the signing of a starting quarterback as a Catch- ...

Tennis Strategy
Players use different strategies while playing tennis to enhance their own strengths and exploit their opponent's weaknesses in order to gain the advantage and win more points. Players typically specialize or naturally play in a certain way, based on what they can do best. Based on their style, players generally fit into one of three types, ''baseliners'', ''volleyers'', ''all-court players''. Many players have attributes of all three categories but, at times, may also focus on just one style based on the surface, or on the condition, or on the opponent. A ''baseliner'' plays from the back of the tennis court, around/behind/within the baseline, preferring to hit groundstrokes, thereby allowing themselves more time to react to their opponent's shots, rather than to come up to the net (except in certain situations). Many modern professional players employ this style most of the time. A ''volleyer'' plays nearer towards the net, preferring to hit volleys, whereby providing their o ...

Tennis
Tennis is a racket sport that is played either individually against a single opponent ( singles) or between two teams of two players each ( doubles). Each player uses a tennis racket that is strung with cord to strike a hollow rubber ball covered with felt over or around a net and into the opponent's court. The object of the game is to manoeuvre the ball in such a way that the opponent is not able to play a valid return. The player who is unable to return the ball validly will not gain a point, while the opposite player will. Tennis is an Olympic sport and is played at all levels of society and at all ages. The sport can be played by anyone who can hold a racket, including wheelchair users. The modern game of tennis originated in Birmingham, England, in the late 19th century as lawn tennis. It had close connections both to various field (lawn) games such as croquet and bowls as well as to the older racket sport today called real tennis. The rules of modern tennis have ...
