Key result
A novel VO2peak prediction equation using treadmill test duration and body mass yielded lower cross-validation errors (SEE = 2.5 mL·kg⁻¹·min⁻¹) than previously published equations in male adolescents.
Why the study?
Can a VO2peak prediction equation be accurately developed and validated from a maximal treadmill test in active male adolescents?
Observational (n=88)

Effect estimate: R = 0.54
A newly developed VO2peak prediction equation based on treadmill test duration and body mass demonstrated better cross-validation accuracy than previously published equations in active male adolescents.
May improve VO2peak estimation in active male adolescents; extends prior equations but leaves open prospective validation.
The aims were to develop and validate a VO(2peak) 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 VO(2peak) (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⁻¹min⁻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 VO(2peak) using anthropometric data, performance in 20mST, and energy cost at submaximal speeds.

Tsiaras et al. (2010) conducted an observational in Active male adolescents (n=88). Treadmill running test prediction equation vs. Previously published equations was evaluated on Cross-validation statistics for VO2peak prediction (R, CE, SEE, TE) (R = 0.54). A novel VO2peak prediction equation using treadmill test duration and body mass yielded lower cross-validation errors (SEE = 2.5 mL·kg⁻¹·min⁻¹) than previously published equations in male adolescents.
