Olympic Games
The Olympic Games programme consists of 35 sports, 30 disciplines and 408 events. For example, wrestling is a Summer Olympic sport, comprising two disciplines: Greco-Roman and Freestyle. It is further broken down into fourteen events for men and four events for women, each representing a different weight class. The Summer Olympics programme includes 26 sports, while the Winter Olympics programme features 15 sports. Athletics, swimming, fencing, and artistic gymnastics are the only summer sports that have never been absent from the Olympic programme. Cross-country skiing, figure skating, ice hockey, Nordic combined, ski jumping, and speed skating have been featured at every Winter Olympics programme since its inception in 1924. Current Olympic sports, like badminton, basketball, and volleyball, first appeared on the programme as demonstration sports, and were later promoted to full Olympic sports. Some sports that were featured in earlier Games were later dropped from the programme.
Pan American Games sports
The Pan American Games sports comprise all the sports contested in the Summer Olympic Games. In addition, traditional and popular sports throughout the Americas which are not contested at the Olympic Games are also contested such as bowling and baseball. As of 2015, the Pan American Games included 36 sports with 51 disciplines and 364 events. The number and kinds of events may change slightly from one Pan American Games to another.
