Abstract With the change of people’s parenting concept, Chinese residents tend to let children sit in daily life, which will lead to the continuous decline of children’s physical health. Therefore, the detection rate of obesity and overweight of children in China continues to rise, which requires kindergartens to choose a more efficient physical exercise method. Through scientific physical health education, we can guide children to pay attention to physical exercise, which will help them acquire lifelong sports awareness and ability. At the same time, physical health education can promote children’s health, which is also the most effective measure. Therefore, some kindergartens have formed children’s physical education curriculum with the help of modern information technology, which will help children better develop their physical quality. However, some kindergartens also have some problems when introducing physical fitness courses, such as lack of experience, lack of understanding of concepts, curriculum confusion, etc., which will be difficult to fully reflect the development of physical fitness. First of all, this paper analyzes the impact of physical training on children. Then, this paper analyzes the problems of modern information technology. Finally, some suggestions are put forward.
