Aerobic Fitness and Physical Activity in Children

In Volume 1 of Pediatric Exercise Science (PES), a paper by Fenster et al. (25) investigated the relationship between peak oxygen uptake (peak V . O 2 ) and physical activity (PA) in 6-to 8-year-old children. They used both questionnaires and large-scale integrated activity monitors (LSIs) to estimate daily PA and determined peak V . O 2 using an incremental treadmill test to volitional exhaustion. They concluded that peak V . O 2 correlated well with PA as measured by LSIs but commented that

O 2 and PA are the most researched and reported variables in the 25-year history of PES. Yet, the assessment and interpretation of young people's aerobic fitness and PA remain problematic and any meaningful relationship between them during childhood and adolescence is shrouded with controversy. The present paper uses Fenster et al.'s (25) report as an indicator of where we were 25 years ago, outlines how far we have advanced since then, and suggests future directions of research in the study of aerobic fitness and PA.
