This final paper will discuss obesity, its causes, consequences, and types of kinesiology activities, as well as the importance of any form of activity on children's health and quality of life. In recent years, obesity has become an increasingly common problem for preschool children and young people, which can have serious consequences for their health. In addition to the constantly increasing percentage of obesity, the percentage of physical activity is constantly decreasing, especially among young people. Physical inactivity and overweight are widespread worldwide and cause major health problems. Early childhood is the time to adopt healthy lifestyle habits. By encouraging children to adopt healthy lifestyle and eating habits and engage in and enjoy sports activities, they can be helped to avoid future health problems. Regular play and physical activity are a key part of children's growth and development. Being active in activities such as dancing, running, cycling, jumping, climbing or playing any game can greatly contribute to building their musculature and improving motor skills, acquiring new knowledge and skills, cognitive, emotional, social and physical growth and development. Physical activity along with proper nutrition is the most important factor in the prevention of obesity in children. The aim and purpose of this paper is to clarify the concept of obesity and to focus on the types of kinesiological activities and to point out their importance. In addition to the fact that kinesiology activity promotes the physical growth and development of children, a healthy, dexterous and agile child will be able to perform their work tasks more easily and deal with all the difficulties in life. Therefore, it is necessary to leave time for engaging in kinesiology activity, just to reduce the negativity due to not engaging in it.
