Why the study?
CPET in preschoolers is challenging and studies have mostly been limited to older children, despite knowledge of performance being essential to evaluate cardiorespiratory fitness.
Does an age-appropriate outdoor cardiopulmonary exercise test using a mobile device improve the achievement of maximal cardiopulmonary parameters compared to a modified Bruce protocol on an indoor treadmill in healthy preschool children?
Does an age-appropriate outdoor cardiopulmonary exercise test using a mobile device improve the achievement of maximal cardiopulmonary parameters compared to a modified Bruce protocol on an indoor treadmill in healthy preschool children?
Outdoor mobile CPET in preschoolers yields significantly higher maximal cardiopulmonary values in a shorter time compared to traditional indoor treadmill testing, offering a more age-appropriate alternative.
No takes yet. Share an insight, caveat, or question.
May support outdoor mobile CPET as more age-appropriate in preschoolers; hypothesis-generating and requires prospective validation before practice change.
Rottermann et al. (2022) studied this question.
