摘要：Mendez-Cornejo J, Gomez-Campos R, Andruske C, SullaTorres J, Urra-Albornoz C, Urzua-Alul L, Cossio-BolanosM. Maximum Oxygen Consumption: Validity of the Run Testof 20 Meters and Proposal of Equations for Prediction inYoung People. JEPonline 2020;23(1):24-37. The purpose ofthis study was: (a) to verify the validity of a 20 m round triprun test for young athletes; and (b) to propose regressionequations for predicting VO2 max in young athletes. Thesample for this study consisted of 31 young universitystudents. Age ranged from 18 to 24 yrs old. The absolute(L∙min-1) and relative (mL∙kg-1∙min-1) VO2 max values weremeasured with a test in the laboratory and in the field (20 mround trip run test). Weight, standing height, body fatpercentage (BF%), fat mass (FM), lean mass (LM), andmaximum expiratory flow (MEF) were also measured. Nodifferences were found between the laboratory and the fieldrun tests in absolute terms (criterion X = 49.3 ± 9.8 L∙min-1,field X = 49.3 ± 9.8 L∙min-1) and relative (criterion X = 3.3 ±0.8 mL∙kg-1∙min-1 field X = 3.4 ± 0.8 mL∙kg-1∙min-1). Thecoefficient of concordance index (CCI) varied from 0.89 to0.95. Three equations were created for the absolute VO2 max:(R2= 90 to 94%), and three other equations for the relative VO2 max: (R2= 73 to 76%). The six equations demonstrated high values for DesirableReproducibility Indexes (DRI) (precision 0.85 to 0.97) and (accuracy 0.94 to 0.99). The 20 mBack and Forth Run Test is valid for estimating absolute and relative VO2 max in youngathletes. Furthermore, the six equations developed for both sexes provide a reasonablealternative for evaluating aerobic fitness in the health and sport sciences context.
