Effects of Physical Activity on Motor Skills and Cognitive Development in Early Childhood: A Systematic Review.

Abstract: Objective. This study synthesized literature concerning casual evidence of effects of various physical activity programs on motor skills and cognitive development in typically developed preschool children. Methods. Electronic databases were searched through July 2017. Peer-reviewed randomized controlled trials (RCTs) examining the effectiveness of physical activity on motor skills and cognitive development in healthy young children (4–6 years) were screened. Results. A total of 15 RCTs were included. Of the 10 studies assessing the effects of physical activity on motor skills, eight (80%) reported significant improvements in motor performance and one observed mixed findings, but one failed to promote any beneficial outcomes. Of the five studies investigating the influence of physical activity on cognitive development, four (80%) showed significant and positive changes in language learning, academic achievement, attention, and working memory. Notably, one indicated no significant improvements were observed after the intervention. Conclusions. Findings support causal evidence of effects of physical activity on both motor skills and cognitive development in preschool children. Given the shortage of available studies, future research with large representative samples is warranted to explore the relationships between physical activity and cognitive domains as well as strengthen and confirm the dose-response evidence in early childhood.

Exergaming Impact on Physical Activity and Interest in Elementary School Children

Abstract: In this study, I explored the impact of exergaming on in-class physical activity (PA) and motivation in physical education. Elementary children participated in a 4-week exergaming unit and a 4-week fitness unit. At test showed the children's in-class PA in the exergaming unit was significantly lower than in the fitness unit. Results also indicated that students' situational interest in exergaming was significantly higher than in the fitness unit at the beginning and end of instruction. Children's interest declined significantly in both units and at the same rate. The evidence suggests that exergames may have strong motivational power, but it is premature to claim they will increase physical activity enough for children to receive health benefits in physical education.

Learning in Physical Education: A Self-Determination Theory Perspective

Abstract: The purpose of this study was to review the literature relevant to learning in physical education (PE) according to the self-determination theory (SDT). In this literature review, we first provide an overview of SDT. Second, we discuss students’ SDT-related motivational profiles in PE. Third, we illustrate the relationships among students’ perceptions of the nature of an autonomy-supportive or controlling learning environment, need satisfaction, and self-determined motivation. Fourth, we explore the impact of SDT on students’ learning in PE with respect to the cognitive, psychomotor, and affective learning domains. Finally, we articulate the pedagogical implications on the basis of the reviewed SDT research and future directions for SDT research in PE.

Reliability and validity

Abstract: Definition: To what extent does the study allow us to draw conclusions about a causal effect between two or more constructs? Issues: Selection, maturation, history, mortality, testing, regression towrd the mean, selection by maturation, treatment by mortality, treatment by testing, measured treatment variables Increase: Eliminate the threats, above all do experimental manipulations, random assignment, and counterbalancing.

Educating the Student Body: Taking Physical Activity and Physical Education to School

Abstract: Physical inactivity is a key determinant of health across the lifespan. A lack of activity increases the risk of heart disease, colon and breast cancer, diabetes mellitus, hypertension, osteoporosis, anxiety and depression and others diseases. Emerging literature has suggested that in terms of mortality, the global population health burden of physical inactivity approaches that of cigarette smoking. The prevalence and substantial disease risk associated with physical inactivity has been described as a pandemic.The prevalence, health impact, and evidence of changeability all have resulted in calls for action to increase physical activity across the lifespan. In response to the need to find ways to make physical activity a health priority for youth, the Institute of Medicine's Committee on Physical Activity and Physical Education in the School Environment was formed. Its purpose was to review the current status of physical activity and physical education in the school environment, including before, during, and after school, and examine the influences of physical activity and physical education on the short and long term physical, cognitive and brain, and psychosocial health and development of children and adolescents. Educating the Student Body makes recommendations about approaches for strengthening and improving programs and policies for physical activity and physical education in the school environment. This report lays out a set of guiding principles to guide its work on these tasks. These included: recognizing the benefits of instilling life-long physical activity habits in children; the value of using systems thinking in improving physical activity and physical education in the school environment; the recognition of current disparities in opportunities and the need to achieve equity in physical activity and physical education; the importance of considering all types of school environments; the need to take into consideration the diversity of students as recommendations are developed.This report will be of interest to local and national policymakers, school officials, teachers, and the education community, researchers, professional organizations, and parents interested in physical activity, physical education, and health for school-aged children and adolescents.
