Calculating an equation to estimate the maximum oxygen uptake in lifeguards." International Journal of Aquatic Research and Education", v.13, n.1. https://doi.org/10.25035/ijare.13.01.03http://hdl.handle.net/2183/38544[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.engThis Research Article is brought to you for free and open access by the Journals at ScholarWorks@BGSU.http://creativecommons.org/licenses/by-nc-nd/3.0/es/Ecuación de regresiónSocorristaAbsorción máxima de oxígenoForma físicaRegression equationLifeguardMaximum oxygen uptakePhysical fitnessjournal articleopen accesshttps://doi.org/10.25035/ijare.13.01.03
