The importance of physical activity is gaining recognition in children with cardiac or respiratory diseases, and the measurement of heart rate (HR) response during exercise is required.1 The 6-minute walking test (6MWT), which has been verified for validity and reliability in children,2 is the reference field test to measure functional exercise capacity. New field tests are emerging to counteract the practical drawbacks associated with the 6MWT. The 1-minute sit-tostand test (STST) is easy to implement and has already been validated in adults,3 but not yet in children. Moreover, to our knowledge, the physiological response associated with this test is unknown in children. The aims of this study were to evaluate the concurrent validity and reliability of the STST in measuring the HR response to submaximal exercise and functional exercise capacity in children.
