Previous research confirms the positive impact of kinesiology activities on child development, including the emotional aspect. Through physical activity, children learn to cope with unpleasant feelings. Emotion regulation refers to the management of emotions and the strategies we use to bring the duration or intensity of our emotional states to a comfortable level that allows us to achieve our desired goal. To this end, a study was conducted to determine the effects of kinesiological activities, in this case sport climbing, on emotions and emotion regulation in children. The study was conducted in person by completing a questionnaire orally. Twenty children and one coach participated in the study. The results showed a positive influence on emotions and a positive effect on emotion regulation. A noticeable increase in children's self-confidence when engaged in sport climbing and overcoming the fear of heights. Kinesiological activity provides the opportunity to express and express emotions in a natural and spontaneous way. When engaging in a kinesiological activity, a child can feel satisfaction and achievement when he successfully overcomes new challenges. This can result in an increased sense of self-confidence and pride, which has a positive impact on emotional development.
