Abstract

ABSTRACT Field-based tests of aerobic fitness that can be administered quickly and do not require maximal effort are desirable. The purpose was to develop and validate quarter-mile walk tests for 10–13-year-olds. Participants (N = 59) walked one mile on two different days. Walk times, heart rates, body mass, physical activity, and aerobic fitness were assessed. Multiple regression was used to develop models to estimate VO2max. Quarter-mile walk models provided estimates of aerobic fitness that were similar in accuracy to previously published walk tests. The recommended model that balances accuracy and ease of administration was: VO2max = 119.691–(13.744*quarter-mile walk time [min])–(0.168*heart rate), R=.73, SEE = 6.84 mL·kg−1·min−1. Walk times, heart rates, and estimated VO2max values were highly reliable. The walk tests developed provide valid estimates of VO2max, are easy to administer, and could be particularly useful for unmotivated or overweight children when this equation is confirmed with a larger sample in group testing conditions.
