MAPS “Multisport Against Physical Sedentary” partnership (IT, DE, GR, HR, NL, PL, PT, TR), according with the HEPA guidelines, aims to create a European multisport methodology against obesity, sedentary lifestyle and dropout among youngsters aged between 9 and 12.This project involves and brings together a group of organizations actively engaged in sports or in research data on issues collateral to the sports’ world.Starting from a model already tested in Italy, at the national level, and the collection of other partners’ good practices, a new shared model will be designed and tested in the participating countries. It will include training modules for local trainers and coaches and multisport activities for boys and girls, guided by the previously trained sports experts.MAPS tries to find ways for promoting physical activity in all its aspects by encouraging children to practice multisport and also through passive factors like urban travel habits and urban structure: for this reason the project will include a study about the impact of the urban asset on the children’s motor habits.It has been shown that the practice of multisport is functional to influence, harmoniously and completely, the motricity development of the young . In fact, during the adolescent growth stages it is highly recommended to workout mixing various motor gestures instead of repeating constantly the same ones because only in this way it is possible to complete the motor scheme that the young has to develop and consolidate for a future healthy life.The partnership will adopt and test the MAPS method in 7 countries with the collaboration of 35 trainers and 84 local coaches specifically trained for becoming “Multisport Trainers” , involving 76 sport teams and more than 900 boys and girls. The Multisport Trainers will share and record the data of their experience simultaneously thanks to an APP, available for smartphone and tablet, created ad hoc.
