Calculating an Equation to Estimate the Maximum Oxygen Uptake in Lifeguards

Abstract

[Abstract]: The aim of this study was to derive an equation that validly and reliably stimates the VO2 reached in the IPTL, a maximum stress test for lifeguards. From the results obtained in the first part of the research, a multiple linear egression model was identified. A "stepwise" procedure was established as a ariable selection method, where the VO2IPTL was selected as the dependent ariable and the maximum time reached in the IPTL (s), the percentage of muscle mass (%) and weight of the participant (kg), as independent variables. This procedure generated a regression model where a high correlation was bserved between the 3 independent variables and the dependent variable (R2 = .84; p <.01). From this model, an equation could be generated that allows stimating the VO2max reached in the IPTL. The analysis of the results uggested that the IPTL was a valid and reliable test to estimate VO2 simply hich would allow, in the long term, analysis of changes in lifeguards physical onditioning.
