New 20 m Progressive Shuttle Test Protocol and Equation for Predicting the Maximal Oxygen Uptake of Korean Adolescents Aged 13-18 Years.

: Although several equations for predicting VO in children and adolescents have been reported, the validity of application of these equations to the Korean population has not been verified. The purpose of study was to develop and validate regression models to estimate maximal oxygen uptake (VO) using a newly developed 20 m progressive shuttle test (20 m PST) protocol in Korean male ( = 80, 15.3 ± 1.
