The Gymnasiade, or World Gymnasiade, is an international multi-sport event which is organised by the International School Sport Federation (ISF). It is the largest event among many other sport events held by the ISF. The fifteenth ISF Gymnasiade was organised Brazil in 2013 with more than 1700 young athletes representing 37 countries. Aligned with the philosophy of the organisation, only pupils between the ages of 13 and 18 are eligible to compete.
There are four main sporting competitions at each Gymnasiade: athletics, artistic gymnastics, rhythmic gymnastics, and swimming. Other disciplines may be added upon the request of the organising country, such as trampoline, aerobics. There are 34 athletics events (17 for boys and 17 for girls), which are held in agreement with the IAAF rules. The events are split equally between the genders. Demonstration sports will be displayed as part of the programme. These are Judo, Karate, Wrestling, Chess, Tennis, Archery.
The first edition of the Gymnasiade was held in 1974 in Wiesbaden, Germany and it featured solely gymnastics competitions and swimming. The athletics competition was added to the programme in the following edition in Orléans in 1976. The Gymnasiade continued as a biennial event until 1990, when it was altered to a quadrennial schedule. The next editions will be held in Trabzon, Turkey in 2016 and Morocco in 2018.
