A recent study referred to as “FITKids” demonstrated the extent to which physical activity can improve body composition, which is important as it contributes to overall health. The study included 220 eight- to nine-year-olds who were assigned to either a nine-month physical activity program that required 70 minutes of moderate to vigorous physical activity five days a week or a control group. Researchers measured baseline and follow-up cardiorespiratory fitness, percent fat mass, percent central fat mass, and estimated abdominal fat tissue. The FITKids showed improved cardiovascular fitness, less body fat, and carried less fat around their abdomens. The opposite was true for the control group who maintained their regular after-school routine.
