Exercises are indispensable for a child’s development. By doing sport children get to know how to strengthen their personality and self-confidence. They learn how to deal with themselves, how to get in touch with others and develop their social skills. In addition, children learn more about themselves and their body – its possibilities and limitations: fun, adventure, strength, power, relaxation, fatigue and exhaustion. They also perceive the surroundings and influences: What is on top, what is at the bottom? What is fast, what is slow? Which forces act in which form of motion? Sport helps children to pool knowledge and experience and is part of a very important process in the development of their personality. Therefore, sport represents an optimal instrument to motivate children to move and exercise.
