Aerobic physical activity among third- to sixth-grade children

We observed the level of activity, and determined which of 24 third- to sixth-grade children were present during that activity, for two weekdays per child. No events of aerobic activity, as defined by nationally accepted criteria, were detected in that 48 days of observation. By a less stringent criterion, only half the children engaged in aerobic activity on any one day. With regard to who was active, there was no evidence for day-to-day consistency. Fathers were virtually absent during periods of activity. Issues relating to promoting aerobic activity are discussed.
