Abstract: Physical activity in preschool period is closely related with the development of bone,cardiopulmonary health,motor,cognition and mental health. Moreover,it will continue to influence their health throughout the course of life. Over the past few years,some developed countries,like Canada and Australia,and World Health Organization have published their physical activity guidelines for children in early childhood. However,there are not yet physical activity guidelines for Chinese preschoolers aged 3-6 years. The Physical Activity Guidelines for Chinese Preschoolers (3-6 years old),hereinafter referred to as the "Guidelines",was jointly developed by Capital Institute of Pediatrics,Beijing Sport University,and China Institute of Sports Science from General Administration of Sport of China under an expert team from sports science,pediatrics and public health. The process of developing the Guidelines follows strict and transparent principle,drawing on the Appraisal of Guidelines for Research and Evaluation (AGREE) Ⅱ instrument,adopting the method of literature materials,and sorting out the relevant guidelines and research evidence of foreign preschool children on the basis of systematically searching,forming the core issues and the draft of the recommendations of the guidelines. After repeated discussions and revisions through five rounds of expert consensus meetings,the Guidelines was finally completed. As the first physical activity guideline for preschoolers in China,the Guidelines comprehensively considers movement behaviors of preschoolers in 24 hours of daily life,including physical activity,sedentary behavior and sleep. On this basis,it raises ten key recommendations in four aspects including the principles of preschool children′s physical activity,physical activity time,types of physical activity,and physical activity monitoring and evaluation. The Guidelines provides recommendations for parents,health care professionals,kindergarten teachers and parents,so as to give professional guidance on scientific and safe physical activities for Chinese preschoolers and meet their developmental needs.
