at the first modern olympic Games in 1896, there were just nine different sports: athletics, cycling, fencing, gymnastics, shooting, swimming, tennis, weightlifting and wrestling.in tokyo, there will be 33 different sports represented by 50 separate disciplines across 339 events.
That's an awful lot of sport to cram into 17 days of competition.well, in addition to the 28 core sports, there have been five additions to the Tokyo program to improve local interest: karate, sport climbing, surfing, skateboarding and baseball/softball.
