%X Cardiorespiratory fitness (CRF) is an important indicator of adolescent cardiovascular well-being and future cardiometabolic health but not always feasible to measure. The purpose of this study was to estimate the concurrent validity of the non-exercise test (NET) for adolescents against the Progressive Aerobic Capacity Endurance Run (PACER £¿) and direct measures of VO 2max as well as to examine the concurrent validity of the PACER £¿ with a portable metabolic system (K4b 2£¿). Forty-six adolescents (12¨C17 years) completed the NET prior to performing the PACER £¿ while wearing the K4b 2£¿. The obtained VO 2max values were compared using linear regression, intra-class correlation (ICC), and Bland¨CAltman plots, and ¦Á was set at 0.05. The VO 2max acquired directly from the K4b 2£¿ was significantly correlated to the VO 2max indirectly estimated from the NET ( r = 0.73, p < 0.001, r 2 = 0.53, ICC = 0.67). PACER £¿ results were significantly related to the VO 2max estimates from the NET ( r = 0.81, p < 0.001, r 2 = 0.65, ICC = 0.72). Direct measures from the K4b 2£¿ were significantly correlated to the VO 2max estimates from the PACER £¿ ( r = 0.87, p < 0.001, r 2 = 0.75, ICC = 0.93). The NET is a valid measure of CRF in adolescents and can be used when an exercise test is not feasible. View Full-Tex
