An analysis has revealed that the models for females ( RMSE C V 4.07 mLkg 1 min 1 ) are characterised by a smaller degree of error as compared to male models ( RMSE C V 5.30 mLkg 1 min 1 ). The model accounting for sex generated an error level of RMSE C V 4.78 mLkg 1 min 1.

This study presents mathematical models for predicting VO 2 max based on a 20 m shuttle run and anthropometric parameters.

The research was conducted with data provided by 308 young healthy people (aged 20.6 1.6).

Twenty-four variables were used to build the models, including one dependent variable and 23 independent variables.

The predictive methods of analysis include: the classical model of ordinary least squares (OLS) regression, regularized methods such as ridge regression and Lasso regression, artificial neural networks such as the multilayer perceptron (MLP) and radial basis function (RBF) network.

All models were calculated in R software (version 3.5.0, R Foundation for Statistical Computing, Vienna, Austria).

In order to compare and choose the best model, leave-one-out cross-validation (LOOCV) was used.

The paper presents three types of models: for females, males and the whole group.

An analysis has revealed that the models for females ( RMSE C V 4.07 mLkg 1 min 1 ) are characterised by a smaller degree of error as compared to male models ( RMSE C V 5.30 mLkg 1 min 1 ).

The model accounting for sex generated an error level of RMSE C V 4.78 mLkg 1 min 1.
