Every four years, the Summer Olympics are a significant international sports competition. In a variety of various sports, the world's finest athletes compete against one another. Gymnastics, track and field, aquatics, rowing, boxing, archery, and other sports are included in the Summer Olympics. At one period or another, the Olympics counted up to a total of 42 sports.

There will also be many classics, ranging from ever-popular events like gymnastics and athletics to team sports. We can expect to see the return of superstars such as 2016 gymnastics standouts such as Simone Biles, Katie Ledecky, Sydney McLaughlin, who competed in the Rio Olympics at the age of 16 and has been on the rise ever since.

The Summer Olympic Games in Tokyo will include a somewhat altered program of events. At the 2020 OG, new sports such as 3x3 soccer, BMX freestyle, Madison biking, and more mixed events will debut. Some appear to be obvious options, but there are a plethora of other sports that deserve a chance to compete for gold.

Which popular sports are not included in the Olympic Games and why?

The Olympics are one of the most popular international multi-sport events, but in order to keep the games manageable, not all sports, including some very popular ones could be included. Check out which popular sports are not included in the Olympic Games and why.

American Football

It appeared at the 1932 Olympics but was never seen again. Maybe the US would have a minor edge over other nations, or the organizers of the Olympic Games may not be interested in some sport's tragedy. It would have been nice to see some of the finest NFL athletes get together.

Mixed Martial Arts (MMA)

Mixed Martial Arts is a brutal yet fascinating sport. The Olympics' main focus is safety, however, the MMA fighters do not wear helmets or padding. MMA connects participants and spectators back to the Olympic Games' Ancient Greek origins. In the ancient Games, athletes would fight aggressively and viciously with some restrictions in mind. Boxing, wrestling, and martial arts methods were utilized to battle, similar to today's MMA combat.

Cricket

British sport, Cricket, has over 2,5 billion admirers and is the world's second most-watched sport in the world. Cricket is not part of the Olympics despite its huge fanbase. It took place during the inaugural modern games in 1896 but was retired later as a result of a lack of participants. 

Polo

Polo has witnessed a comeback in popularity in recent years and is one of the most prestigious games, but since 1936, it has not been part of the Olympics.

Chess

In the 1920s, the IOC acknowledged chess as a sport. It was planned to be part of the Paris 1924 Games, but it was eventually omitted because it was difficult to distinguish between amateur and professional players. The World Chess Federation calls for the sport's inclusion in the Olympics, and the organization often drug tests players to ensure they are abiding by the IOC's regulations.

Squash

Roughly 17 million people worldwide play squash, however, its last formal attempt to be included in the Olympics was denied in favor of wrestling. For the 2024 Olympics, a fresh bid looks likely.

Bowling

Bowling dates to ancient Egyptian people, as Old Egyptians played a bowling-like game that was its first known predecessor. As a showcase sport at the Seoul Games, bowling has been incorporated into the Olympics momentarily. However, there were only 20 participating countries, and since that time, this particular sport has not reappeared.
