Physical exercise plays an important role in a child's life. It is necessary for proper growth and development of the child. Numerous studies have shown that children spend more and more time sitting in front of the television or playing computer games. The activities we carry out with children must be adapted to their abilities and their age. It is important to program and plan them in order to achieve the set goals. Parents also play a big role. They can participate in physical activities together with the children, but they can also enroll them in various sports such as basketball, volleyball, football or swimming. Physical exercise is closely related to health. It helps in the prevention of diseases of the movement system and chronic diseases. Movement is one of the basic human needs, which develops from an early age, so it is necessary to activate children and encourage them to engage in physical activities, while reducing a sedentary lifestyle. Lack of physical exercise can lead to certain absences such as incorrect posture, flat feet, excess body weight, reduced function of the movement system and weaker functioning of the circulatory system. The role of educators in conducting physical exercise is very important because they need to be loud and cheerful, clear and loud so that the children understand what they are doing and to make it more interesting for them. Children who engage in some type of physical exercise or who practice one of the sports are usually more cheerful, full of energy, sociable and happier compared to children who do not engage in physical exercise.
