Mental health represents one of society's biggest challenges, and experts from various scientific disciplines are trying to find solutions that can make adaptation to everyday challenges easier and reduce exposure to psychophysical stress. In such circumstances, interest in the concept of emotional intelligence is increasing. Conducted researches in the field of emotional intelligence has shown that the consequences it carries are spread over different areas, and a large amount of knowledge about the competencies of emotional intelligence comes from the field of childcare. Regulation of emotional competencies and development of emotional habits can be easily achieved by involving children in some form of physical activity. Physical exercise during primary education ensures harmonious and stable development of children and contributes to their overall health. However, decision on which physical activity a child should participate in is sometimes a challenge. That is because the chosen activity needs to be coordinated with the psychophysical characteristics of the child. Organized physical activities in which students participate should be suitable to their developmental characteristics in order to ensure the possibility of improving those abilities, knowledge and traits that are important in a particular developmental stage. With the mutual cooperation of parents, teachers, coaches and others who participate in raising a child, it is possible to satisfy his individual needs and interests and positively influence on development of self-confidence, self-awareness, self-regulation, empathy, social skills and other competencies that make an emotionally intelligent person.
