Physical Activity During Recess

Physical activity – what can be done by school children and adolescents during recess for 20 minutes?

Introduction

Physical activity is defined as movement involving the skeletal muscles and bones that result in energy   expenditure. Physical activity is influenced by four main variables such as frequency, intensity, types and duration.

Physical activity is important not only for the wellbeing of children and adolescents but also the adults and the elderly. Children and adolescents who are physically active have a better chance of enjoying a healthy adulthood. They generally do not develop chronic diseases such as heart diseases, hypertension, diabetes or osteoporosis.

Physical activity and chronic disease prevention

Obese children and adolescents are at risk of developing various chronic diseases in adulthood such as heart diseases and diabetes. It has been documented that the presence of chronic risk factors in children is associated with low aerobic fitness and low levels of physical activity.

Physical activity recommendations for children and adolescents

It is recommended that children and adolescents accumulate at least 60 minutes of moderate to high intensity physical activity in a day. Physical activities that produce high stresses on the bones such as jumping, running, table tennis, badminton and squash should be emphasized. More importantly physical activities that are generally safe and enjoyed by young should always be encouraged so that they continue to engage in these activities way into their adulthood and beyond. Structured physical activities should also encourage playing for pleasure, entertainment and participation rather than competition.
