Purpose: Lower physical activity in children may contribute to obesity and increased risk of cardiovascular disease. The purpose of the current study was to design a portable and validated step test that predicts aerobic capacity in healthy children aged 7-11 years. Methods: Children were recruited for a single day of testing. Anthropometric measurements and baseline heart rate (HR) were obtained, and then two 3-min step tests (low and high step conditions) were performed in random order. The second test was conducted after HR returned to baseline. Then, participants performed a peak oxygen consumption (peak VO2) test. Results: Of 128 children, 75 were included in our analysis. Heart rate after a step test was inversely related to peak VO2. Predictive model 1 (M1) and predictive model 2 (M2) were developed to predict aerobic capacity. Although M1 included body fat percentage, it was not better than M2 (M1
