Junior Hop project was born out of the passion for sports of a group of organizations that wish to tackle a European problem of children obesity by promoting voluntary activities in sport and awareness of the importance of health-enhancing physical activity through increased participation in, and equal access to, sport for all. The coordinator of this project is the Junior Sport Association. Together with partners from Greece, Bulgaria; Turkey and the Czech Republic, we have formed a consortium in the field of junior sport, with the aim to encourage the participation of children in sports. The project will have a duration of 12 months and is expected to involve more than 200 members of sports organizations, more than 2500 children and more than 50 youth workers in the domain of junior sport. After an intense awareness campaign in all the 5 countries participating about the benefits of sports among children and a seminar on the exchange of good practices between the youth workers in the field of junior sport on the innovative methods of teaching through games, we will organize in the European Week of Sport a hopscotch with the most people playing at the same time as a world’s achievement. The event “Junior Hop” will be registered in the Guinness Book as the most people playing hopscotch simultaneously. Our project brings added value at EU level through results as: one short movie with good practices in junior sport teaching from 5 countries; 1 seminar especially conceived for youth workers in the domain of junior sport, a Junior’s Guides with good practices and recommendations for the improvement of sport curriculum at the level of sports students that want to become sports teachers in primary and secondary school and also at the level of schools. Through this project we will put the basis of a strong collaborative partnership, where public and private sectors work together to tackle big challenges as child obesity and poor curriculum in sports.
