Sport (British English) or sports (American English) includes all forms of competitive physical activity or games which, through casual or organised participation, aim to use, maintain or improve physical ability and skills while providing enjoyment to participants, and in some cases, entertainment for spectators. Usually the contest or game is between two sides, each attempting to exceed the other. Some sports allow a tie game; others provide tie-breaking methods, to ensure one winner and one loser. A number of such two-sided contests may be arranged in a tournament producing a champion. Many sports leagues make an annual champion by arranging games in a regular sports season, followed in some cases by playoffs. Hundreds of sports exist, from those between single contestants, through to those with hundreds of simultaneous participants, either in teams or competing as individuals. In certain sports such as racing, many contestants may compete, each against each other, with one winner.

The Liber Abaci Institute have a new point of view of the sports on this present days and a new way to play association football named Fibonacci Football.

The team sports are an organized physical activity that requires different skills. The different sports have a diagram of the fuctions and positionings in the court.

The basquetball have players that can handle all of the positions and all of the functions and the best examples are Michael Jordan & Lebron James, capables of being the best attacker and the best defender and fullfilling every function in the field.

The sports are evolving constantly and the players every generation get more complete about their individual techniques. The perfect example of this progress is the association football or football soccer, as the attackers, midfielders and defenders are more skilled through time being able to cover other positions and functions.

The football defenders and attackers have a more defined function but also as the midfielders are a mix or gamma of skills as every player is unique. The midfielders have more variations about their individual techniques covering more areas of the court and continuously evolving to get more complete.

The "Player 23" is called to this complete football athete that performs all the positions in the field, having the best examples with: Toure Yaya, Radja Nainggolan, Paul Pogba, Marco Verrati, Arturo Vidal, Corentin Tolisso, Rodolfo Pizzarro & Marco van Ginkel being this last one more weak defensively.

Those players have the same profile being a complete central midfielder and also we have another example with Miguel Layun with the difference that he is a fast left wing back principally and right sided being an extra striker on attack and can fulfill also the wing function, every central midfielder position and can be an excellent central defender.

This artfulness players are natural leaders and are capable to defend and attack with high precision & dexterity, also they fulfill every area in the midfield. They totally complete the function of a central defender being able to defend better than the majority of the performers on this position, also they complete the function of a wing back as they are fast and they know how to cross the ball with accuracy.

The Player 23 is highly creative and they are perfect passers, conducers and retainers. Their defensives skills allow them to be excellent ball thieves. They have a high capacity of concentration in speed that gives them an excellent vision and awareness of the field to pass, receive and orquestate. They constant assist the scorers and they fully perform the functions of a wing. The Player 23 is perfect as a midfielder having the necessary skills to develop the different positions.

This complete athletes also are excelent forwards being dangerous outside and inside the striking area. They have capacity, accuracy and strength to shoot from long distances. Inside the area they are able to control the adrenaline of the goal definition being harmful like a central striker and having concepts enough to knock the ball with the head.

They have a fascinating way to move inside the court: excelent positioning inside the striking area, a perfect way of moving to recieve the ball through the midfield and precise defensive anticipation to rob the ball.

The Player 23 is the most complete football player being capable to cover every position and function in the battlefield, defending, creating & attacking with high preciseness and cunning. They perform better than most all players of the FIFA of any position (only by not taking into account the position of goalkeeper) being most complete football athletes of the History.

The Player 23 is the product of more than hundred years of the progress of the association football.

Boxing is a combat sport in which two people, usually wearing protective gloves, throw punches at each other for a predetermined amount of time in a boxing ring.

Boxing is overseen by a referee over a series of one- to three-minute intervals called rounds. The result is decided when an opponent is deemed incapable to continue by a referee, is disqualified for breaking a rule, resigns by throwing in a towel. If a fight completes all of its allocated rounds, the victor is determined by judges' scorecards at the end of the contest. In the event that both fighters gain equal scores from the judges, professional bouts are considered a draw. In Olympic boxing, because a winner must be declared, judges award the content to one fighter on technical criteria.

While humans have fought in hand-to-hand combat since the dawn of human history, the earliest evidence of fist-fighting sporting contests date back to the ancient Middle East in the 3rd and 2nd millennia BCE.[2] The earliest evidence of boxing rules date back to Ancient Greece, where boxing was established as an Olympic game in 688 BC.[2] Boxing evolved from 16th- and 18th-century prizefights, largely in Great Britain, to the forerunner of modern boxing in the mid-19th century with the 1867 introduction of the Marquess of Queensberry Rules.

Mike Tyson and Floyd Mayweather Jr. are two important personages for the sports and specifically for the boxing they are historical figures representing the best expresion of this figthing sport being Tyson the best attacker ever and Mayweather the best defender in the history.

Floyd Joy Mayweather Jr. (born February 24, 1977) is an American professional boxing promoter and former professional boxer. He competed from 1996 to 2007 and 2009 to 2015, and made a one-fight comeback in 2017. During his career, he held multiple world titles in five weight classes and the lineal championship in four weight classes (twice at welterweight), and retired with an undefeated record. As an amateur, Mayweather won a bronze medal in the featherweight division at the 1996 Olympics, three U.S. Golden Gloves championships (at light flyweight, flyweight, and featherweight), and the U.S. national championship at featherweight.

Mayweather is a two-time winner of The Ring magazine's Fighter of the Year award (1998 and 2007), a three-time winner of the Boxing Writers Association of America Fighter of the Year award (2007, 2013, and 2015), and a six-time winner of the Best Fighter ESPY Award (2007–2010, 2012–2014). In 2016, Mayweather was ranked by ESPN as the greatest boxer, pound for pound, of the last 25 years. He remains BoxRec's number one fighter of all time, pound for pound, as well as the greatest welterweight of all time. Many sporting news and boxing websites, including The Ring, Sports Illustrated, ESPN, BoxRec, Fox Sports, and Yahoo! Sports, ranked Mayweather as the best pound for pound boxer in the world twice in a span of ten years.

He is often referred to as the best defensive boxer in history, as well as being the most accurate puncher since the existence of CompuBox, having the highest plus–minus ratio in recorded boxing history. Mayweather has a record of 26 consecutive wins in world title fights (10 by KO), 23 wins (9 KOs) in lineal title fights, 24 wins (7 KOs) against former or current world titlists, 12 wins (3 KOs) against former or current lineal champions, and 2 wins (1 KO) against International Boxing Hall of Fame inductees.

Mayweather is one of the most lucrative pay-per-view attractions of all time, in any sport. He topped the Forbes and Sports Illustrated lists of the 50 highest-paid athletes of 2012 and 2013, and the Forbes list again in both 2014 and 2015, listing him as the highest paid athlete in the world. In 2007, he founded his own boxing promotional firm, Mayweather Promotions, after leaving Bob Arum's Top Rank. Mayweather has generated approximately 23.8 million PPV buys and $1.67 billion in revenue throughout his career, surpassing the likes of former top PPV attractions including Mike Tyson, Evander Holyfield, Lennox Lewis, Oscar De La Hoya and Manny Pacquiao.

Michael Gerard Tyson (born June 30, 1966) is an American former professional boxer who competed from 1985 to 2005. He reigned as the undisputed world heavyweight champion and holds the record as the youngest boxer to win a heavyweight title at 20 years, four months and 22 days old. Tyson won his first 19 professional fights by knockout or stoppage, 12 of them in the first round. He won the WBC title in 1986 after stopping Trevor Berbick in the second round, and added the WBA and IBF titles after defeating James Smith and Tony Tucker in 1987. This made Tyson the first heavyweight boxer to simultaneously hold the WBA, WBC and IBF titles, and the only heavyweight to successively unify them.

Tyson became the lineal champion in 1988 when he knocked out Michael Spinks in 91 seconds of the first round.[6] He successfully defended his titles nine times, which included victories over Larry Holmes and Frank Bruno. In 1990, Tyson lost the titles to underdog Buster Douglas, who knocked him out in the tenth round. Attempting to regain the titles, Tyson defeated Donovan Ruddock twice in 1991, but pulled out of a fight with then-undisputed heavyweight champion Evander Holyfield (who had defeated Douglas later in 1990) due to a rib injury.

In 1992, Tyson was convicted of rape and sentenced to six years in prison, but was released on parole after serving three years. After his release in 1995, he engaged in a series of comeback fights. He won the WBC and WBA titles in 1996, after stopping Frank Bruno and Bruce Seldon. With his defeat of Bruno, Tyson joined Floyd Patterson, Muhammad Ali, Tim Witherspoon, Evander Holyfield, and George Foreman as the only men in boxing history to have regained a heavyweight championship after having lost it. After being stripped of the WBC title in the same year, Tyson lost the WBA title to Evander Holyfield by an eleventh round stoppage. Their 1997 rematch ended when Tyson was disqualified for biting Holyfield's ears.

In 2002, Tyson fought for the world heavyweight title again at the age of 35, losing by knockout to Lennox Lewis. Tyson retired from professional boxing in 2006, after being knocked out in consecutive matches against Danny Williams and Kevin McBride. Tyson declared bankruptcy in 2003, despite having received over $30 million for several of his fights and $300 million during his career. At the time the media reported that he had approximately $23 million of debt.

Tyson was well known for his ferocious and intimidating boxing style as well as his controversial behavior inside and outside the ring. Nicknamed "Iron" and "Kid Dynamite" in his early career, and later known as "The Baddest Man on the Planet," Tyson is considered one of the best heavyweights of all time. Tyson holds the third longest unified championship reign in heavyweight history at eight consecutive defenses. He currently ranks #15 in BoxRec's ranking of the greatest heavyweight boxers in history. He was ranked No. 16 on The Ring's list of 100 greatest punchers of all time, and No. 1 in the ESPN.com list of "The Hardest Hitters in Heavyweight History." Sky Sports described him as "perhaps the most ferocious fighter to step into a professional ring." He has been inducted into the International Boxing Hall of Fame and the World Boxing Hall of Fame.

This two figthers will always be in the highest place of the podium of the boxing for their titles, performance, constance, money generated also for being this personages a comercial attraccion for the crowds that will be always on the history of the sports. The only reason for their success is they high performance being Mike Tyson the most powerful and spectacular attacker and Floyd Mayweather an unbeatable skilled defender.

Mike Tyson was not very tall but was having nice muscle work and was naturally heavy, was always hunting the opponent
to react with bursts of blows with extreme power and speed that could knock out the fighters at any time. He used to fight ​with opponents over his weight that sometimes caused problems but his unmatched strength and speed made Tyson triumph over adversity. Myke Tyson is remembered for archiving spectacular victories for knockout since the bursts he made to attack were unstoppable. His impact damage can only be compared with the impact damage of Muhammad Ali.

Tyson will always be remembered with an aggressive reputation after his fight against Holyfield when he bit an ear. Apparently I leave a negative image in society but for the Liber Abaci Institute and for the history of boxing the bite to Holyfield is something pisotivo as it enhances his reputation as an aggressive fighter since he is the best attacker of this sport.

Floyd Mayweather Jr. is totally different from Tyson since the attack is not his priority if not the tactical development of the defense. Mayweather has an expert and neat defense technique, attacking only when the adversary is neglected. Mayweather does not come out on the attack if he does not wait for the opponent like a comparison could be the catenaccio of Italian football that waits for the opponent to attack.
​
This way of fighting Mayweather allows you to be fresh and rested by most rounds to be able to attack when the adversary is neglected throughout the fight, being only one option since the priority is defense and win by desicion of the judges. This sporting behavior has generated a negative reputation of Mayweather resembling cowardice and the fights are very popular because people expect some fighter to stop these defensive tactics knocking him out.​

People have the right to judge the behavior of Mayweather that they understand as negative, but the truth is that this fighter has overcome the barrier of having a good defense to have an almost perfect defense. Mayweather handles a lot of space and makes the opponent look for the attack, tempting the opponent and making a backward, diagonal posture with a lot of elasticity with high speed movements that allows him not to be hit and attack when the opponent is neglected.

These two fighters have the status of commercial phenomena and will be remembered with a bad reputation, but for the Liber Abaci Institute it is positive, since the combat sports are the reflection of a focused aggression. Tyson will be remembered for his impact damage and speed against his opponents, Mayweather will be registered as the most impeccable defender.​

Mike Tyson the best attacker & Floyd Mayweather Jr. The best defender of the History.

The boxing have a variety of techniques and one important aspect of this sport is the combat posture.

The combat posture in boxing depends on the athletes skilled side to have in front the weak side for the jab technique and the skilled side back for the strong impacts.

Having a good posture helps to do not lose the equilibrium, for defending and for attacking better, so the stance switching has not been an option for the pugilistic culture. The reasons is that is very risky as the athlete can lose the equilibrium uncovering the defense and can be hitted or knocked out.

The Liber Abaci Institute have innovate with the stance switching technique that consist on using rigth stance and left stance for attacking and defending.

The stance switching technique can be used steady to give a jab of major impact having the strong side in front. The technique gives major reaching on attack when the switch of sides happens having the possibility to come back in the switched stance for defending jabbing with the strong side. On defense the stance switching can be used to retreat with a greater distance than by not changing position.

This technique must be perfected since it is a high risk movement that can uncover the defence. The loss of balance must be worked with the practice of foot play on the switching movement.

The Fibonacci football have a system with 1 central defender, 2 wing backs, 1 defensive midfielder, 2 creative midfielders, 2 wings and 2 strikers, being an option to use a central striker or 2 attacking midfielders.

The defense will be high pressure and personal, meaning that the team will block from the front of the court and every team player will have the responsability to defend a single player and to block the passing circuit. The system have a defensive stair to use the players in front of the court to have double team defense in the back when needed. The traditional teams have 2 or 3 defenders that never attack and also always a midfielder will have the tendence to defend, so there is a way to use the team players from the front to go down like on a stair to have the double team defense on the attackers of the opposing team.

The  web site will show better how to performe Fibonacci football with the roll of every playing position.
