Longitudinal Predictors of Aerobic Performance in Adolescent Soccer Players
Material and Methods. Players (n=83) were annually followed up during 5 years, resulting in an average of 4.4 observations per player. Decimal CA was calculated, and SA, stature, body weight, and aerobic performance were measured once per year. Fat-free mass (FFM) was estimated from age- and gender-specific anthropometric formulas, and annual volume training was recorded. After testing for multicollinearity, multilevel regression modeling was used to analyze the longitudinal data aligned by CA and SA (Model 1 and 2, respectively) and to develop aerobic performance scores.
Results. The following equations provide estimations of the aerobic performance for young soccer players: ŷ(Model 1 [deviance from the null model =388.50; P<0.01]) =57.75+9.06×centered CA– 0.57×centered CA2+0.03×annual volume training and ŷ(Model 2 [deviance from the null model= 327.98; P<0.01])=13.03+4.04×centered SA–0.12×centered SA2+0.99×FFM+0.03×annual volume training.
Conclusions. The development of aerobic performance in young soccer players was found to be significantly related to CA, biological development, and volume of training.
