Developed in 1934, trampolines were originally used to train astronauts or were used as a training tool for other sports. They soon became popular in their own right and a sport was born.
The first modern trampoline was built by George Nissen and Larry Griswold around 1934 at the University of Iowa. It was initially used to train tumblers and astronauts and as a training tool to develop and hone acrobatic skills for other sports such as diving, gymnastics, and freestyle skiing. People enjoyed the sensation so much, they began to trampoline for sheer fun, and it became popular in its own right.
World Championships were held under the auspices of the FIT (Federation Internationale de Trampolin) from 1964 to 1998. In 1999 The FIT dissolved and trampoline became part of the FIG in order to join the Olympic programme in Sydney 2000.
Canada sent its first trampoline team to the World Championships in Stuttgart, GER in 1972, and when the sport made its Olympic Games debut in Sydney, AUS in 2000, Karen Cockburn won her first Olympic medal – a bronze, and Mathieu Turgeon also took home a bronze medal. Cockburn would go on to win a silver medal at the 2004 Olympic Games and 2008 Olympic Games, becoming one of Canada’s most decorated Olympians. Rosie MacLennan became Canada’s first Olympic champion in trampoline by capturing the gold medal at the 2012 London Olympic Games. She followed it up with a second gold at the 2016 Olympic Games in Rio de Janeiro - becoming the only trampolinist to successfully defend an Olympic title. Rosie was also Canada's Opening Ceremonies Flag bearer at the 2016 Olympic Games.
