Children and Fitness: A Public Health Perspective

Abstract

Abstract The promotion of cardiorespiratory fitness through increased physical activity has become a national public health objective for both adults and children. Based on numerous small-scale studies it appears that children are highly fit but the population distribution is unknown due to the lack of rigorous population studies. Very little is known about the extent of children's physical activity; the available evidence does not support the hypothesis that children obtain sufficient activity to explain their generally high levels of fitness. Due to the lack of evidence of substantial carry-over effects of youth fitness to adult health and the likelihood of children's resistance to vigorous fitness routines, there is little reason to recommend an aerobic training focus in physical education. A focus on enjoyable moderate to vigorous physical activity (MVPA) with carry-over value to adulthood is recommended. Physical education is an important vehicle for promoting physical activity by children; it appears, however, that children may obtain little MVPA during physical education class.
