The aim of this study was to derive an equation that validly and reliably estimates 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 regression model was identified. A "stepwise" procedure was established as a variable selection method, where the VO2IPTL was selected as the dependent variable 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 observed between the 3 independent variables and the dependent variable (R2 = 0.84; p <.01). From this model, an equation could be generated that allows estimating the VO2max reached in the IPTL. The analysis of the results suggested that the IPTL was a valid and reliable test to estimate VO2 simply which would allow, in the long term, analysis of changes in lifeguards physical conditioning.
