The aims were to develop and validate a VO2peak prediction equation from a treadmill running test in active male adolescents. Eighty-eight athletes (12–18 yrs.) performed a maximal exercise test on a treadmill to assess the actual VO2peak and a 20m Shuttle-Run-Test (20mST). A step-wise linear regression analysis was used and the following equation for estimation of VO2peak (mL·kg−1·min−1) = 35.477 + 1.832 × duration in min - 0.010 × duration × body mass in kg was developed. The cross-validation statistics were: R = .54, CE = 0.1 mL·kg−1·min−1, SEE = 2.5 mL·kg−1·min−1 (4.6%), and TE = 2.6 mL·kg−1·min−1 (4.9%). The cross-validation values (CE, SEE, and TE) were lower compared with those of previously published equations in adolescents that estimated VO2peak using anthropometric data, performance in 20mST, and energy cost at submaximal speeds.
