ObjectiveThe purpose of this study was to analyze the validity and provide normative values for the three-min shuttle run test in Spanish preschoolers.MethodsA total of 497 children (mean age 4.83±0.57 years; 47.8% girls) performed the three-min shuttle run test. Posttest body mass index and heart rate values were taken as internal validity indicators.ResultsAge- and sex-specific percentiles for cardiorespiratory fitness were provided. Boys performed better than girls in the test. A significant association was observed between the total distance covered and heart rate (p=0.002). No correlation was found between body mass index and the test score, although the total distance covered by normal weight and obese children was significantly different (296.9 versus. 271.3 m; p=0.013).ConclusionsThis study provides age- and sex-specific cardiorespiratory fitness normative values for the three-min shuttle run test when performed by Spanish preschoolers. This test is an interesting option when the lack of resources limits the measurement of cardiorespiratory fitness in the preschool setting.
