Agility Drill
Agility drills are used in the aim of improving sports agility, which is the ability to change direction and accelerate while in motion. Description The ability to change direction while in motion is very important in many sports but especially in team and dual sports. For example, an American football running back must be able to quickly change direction when he sees an opponent preparing to tackle him. A basketball player must be able to quickly change directions when dribbling the ball, attempting to get back on defense, or when trying to beat an opponent to the ball. A tennis player must be able to quickly change directions when moving to a position where the ball is expected to go but instead finds the ball going in a different direction. Jumping Drills that entail jumping with turns in the air are usually applicable to basketball players and receivers and pass defenders in football but can apply to many sports in interest of strength. Drills that use side jumps and fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agility
Agility or nimbleness is an ability to change the body's list of human positions, position quickly and requires the integration of isolated movement skills using a combination of balance (ability), balance, coordination (physiology), coordination, speed, reflexes, physical strength, strength, and endurance. More specifically, it is dependent on: * Balance – The ability to maintain equilibrium when stationary or moving (i.e. not to fall over) through the coordinated actions of our sensory functions (eyes, ears and the proprioceptive organs in our joints); * Static balance – The ability to retain the center of mass above the base of support in a stationary position; * Dynamic balance – The ability to maintain balance with body movement; * Speed - The ability to move all or part of the body quickly; * Strength - The ability of a muscle or muscle group to overcome a resistance; and lastly, * Coordination – The ability to control the movement of the body in co-operation with the ...

Motion
In physics, motion is the phenomenon in which an object changes its position with respect to time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed and frame of reference to an observer and measuring the change in position of the body relative to that frame with change in time. The branch of physics describing the motion of objects without reference to its cause is called kinematics, while the branch studying forces and their effect on motion is called dynamics. If an object is not changing relative to a given frame of reference, the object is said to be ''at rest'', ''motionless'', ''immobile'', '' stationary'', or to have a constant or time-invariant position with reference to its surroundings. Modern physics holds that, as there is no absolute frame of reference, Newton's concept of '' absolute motion'' cannot be determined. As such, everything in the universe can be considered to be in motion. Motion applies to various p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Running Back
A running back (RB) is a member of the offensive backfield in gridiron football. The primary roles of a running back are to receive American football plays#Offensive terminology, handoffs from the quarterback to Rush (American football)#Offense, rush the ball, to line up as a receiver to catch the ball, and Blocking (American football), block. There are usually one or two running backs on the field for a given play, depending on the offensive formation. A running back may be a Halfback (American football), halfback (in certain contexts also referred to as a "tailback" — see #Halfback/tailback, below), a wingback (American football), wingback or a Fullback (American football), fullback. A running back will sometimes be called a "feature back" if he is the team's starting running back. Halfback/tailback The halfback (HB) or tailback (TB) position is responsible for carrying the ball on the majority of running plays, and may frequently be used as a receiver on ...

Tackle (football Move)
Most forms of football have a move known as a tackle. The primary purposes of tackling are to dispossess an opponent of the ball, to stop the player from gaining ground towards goal or to stop them from carrying out what they intend. The word is used in some contact variations of football to describe the act of physically holding or wrestling a player to the ground. In others, it simply describes one or more methods of contesting for possession of the ball. It can therefore be used as both a defensive or attacking move. Name origin In Middle Dutch, the verb meant to grab or to handle. By the 14th century, this had come to be used for the equipment used for fishing, referring to the rod and reel, etc., and also for that used in sailing, referring to rigging, equipment, or gear used on ships. By the 18th century, a similar use was applied to harnesses or equipment used with horses. Modern use in football comes from the earlier sport of rugby, where the word was used in the 19th ...

Basketball
Basketball is a team sport in which two teams, most commonly of five players each, opposing one another on a rectangular Basketball court, court, compete with the primary objective of #Shooting, shooting a basketball (ball), basketball (approximately in diameter) through the defender's hoop (a basket in diameter mounted high to a Backboard (basketball), backboard at each end of the court, while preventing the opposing team from shooting through their own hoop. A Field goal (basketball), field goal is worth two points, unless made from behind the 3 point line, three-point line, when it is worth three. After a foul, timed play stops and the player fouled or designated to shoot a technical foul is given one, two or three one-point free throws. The team with the most points at the end of the game wins, but if regulation play expires with the score tied, an additional period of play (Overtime (sports), overtime) is mandated. Players advance the ball by bouncing it while walking ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dribbling
In sports, dribbling is maneuvering a ball by one player while moving in a given direction, avoiding defenders' attempts to intercept the ball. A successful dribble will bring the ball past defenders legally and create opportunities to score. Association football In association football, a dribble is one of the most difficult ball skills to master and one of the most useful attacking moves. In typical game play, players attempt to propel the ball toward their opponents' goal through individual control of the ball, such as by dribbling (the usage of technical maneuvers). In order to go past an opponent, dribbling can involve a wide variety of manipulative tricks and feints; Ronaldinho would often employ elaborate skills and feints, such as the '' elastico'', in order to beat defenders. Dribbling is often invaluable especially in the third part of a pitch or at the wings, where most attacks take place. Dribbling creates space in tight situations where the dribbler is marked (cl ...

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 ...

Hurdling
Hurdling is the act of jumping over an obstacle at a high speed or in a sprint. In the early 19th century, hurdlers ran at and jumped over each hurdle (sometimes known as 'burgles'), landing on both feet and checking their forward motion. Today, the dominant step patterns are the 3-step for high hurdles, 7-step for low hurdles, and 15-step for intermediate hurdles. Hurdling is a highly specialized form of obstacle racing, and is part of the sport of athletics. In hurdling events, barriers known as hurdles are set at precisely measured heights and distances. Each athlete must pass over the hurdles; passing under or intentionally knocking over hurdles will result in disqualification. Accidental knocking over of hurdles is not cause for disqualification, but the hurdles are weighted to make doing so disadvantageous. In 1902 Spalding equipment company sold the Foster Patent Safety Hurdle, a wood hurdle. In 1923 some of the wood hurdles weighed each. Hurdle design improvements were ...

Ladder
A ladder is a vertical or inclined set of rungs or steps used for climbing or descending. There are two types: rigid ladders that are self-supporting or that may be leaned against a vertical surface such as a wall, and rollable ladders, such as those made of rope or aluminium, that may be hung from the top. The vertical members of a rigid ladder are called stringers or rails (US) or stiles (UK). Rigid ladders are usually portable, but some types are permanently fixed to a structure, building, or equipment. They are commonly made of metal, wood, or fiberglass, but they have been known to be made of tough plastic. Historical usages Ladders are ancient tools and technology. A ladder is featured in a Mesolithic rock painting that is at least 10,000 years old, depicted in the Spider Caves in Valencia, Spain. The painting depicts two humans using a ladder to reach a wild honeybee nest to harvest honey. The ladder is depicted as long and flexible, possibly made out of some sort of gr ...
