Trampolining has been a popular activity for generations of children, as recreation or competitive sport. 'There aren't too many children in the world that don't like trampolining, as it appeals to their sense of freedom and fun,' says Karen Smith, head of sport at ESF Educational Services. 'You don't have to be good or competitive to enjoy it. In our classes, beginners have as much fun bouncing as our more advanced students who practise somersaults and twists.' ESF Educational Services ( www.esf.org.hk ) runs courses at its Sha Tin and South Island schools, and as part of its summer programme. There are two courses this month: for children aged six years and above, and eight and older. While the senior programme is aimed at experienced trampolinists, the junior course is for beginners and teaches basic skills before moving on to more difficult tasks. Both courses comprise nine, one-hour classes and cost HK$1,800. Multi-Sport ( www.multi-sport.com.hk ) also offers trampolining classes and courses that teach a combination of trampolining and gymnastics skills. There are trampolining courses for children aged five to six and seven years and older. Each course begins by teaching basic moves followed by the introduction of a series of more difficult techniques. Some advanced gymnastics skills are also taught that help to improve participants' trampolining abilities. Courses last nine one-hour lessons and cost HK$1,770. Parents wanting their child to start learning at a younger age can consider the pre-school gym/tramp course for three- and four-year olds, where children are taught how to bounce correctly, followed by individual moves and correct landing techniques. There are nine weekly classes of 45 minutes and the cost is HK$1,500. Parental assistance is required at all classes. There are also combined gymnastics and trampolining courses for older children aged five to seven years and eight to 12. These involve nine one-hour classes and are also HK$1,500. All courses are based on an incentive scheme called Jump for Joy Awards, which sets out a structured sequence of moves that a student must complete before progressing to the next stage. Students will learn the science behind each move, and visual techniques that help in mastering each task.
