The aim of the study was to develop linear models for estimating Maximal Oxygen Uptake (VO2 Max.)of male youth habitat of Delhi. The study was conducted on seventy five healthy male youth of Delhi(attitude: 744feet/127 meters). The age of the subjects ranged from 17 to 25 years The youth were administered with submaximal bench step test (American College of Sports Medicine Protocol) to determine the VO2max.(dependent variable) by plotting HR-workload combinations calculated by Karvonen heart rate reserve method. Data was collected using Cardio-Sport heart rate monitor and step test protocol. The selected independent variables were Age, Body weight in kilograms (B.Wt.), Height in centimeters (Ht.), Resting Heart Rate (RHrest) , Target Heart Rate (THR), Maximal Heart Rate (HRmax.) , Heart Rate at Two minutes of step testing with cadence 15 steps/min (ExHR2), Heart Rate at Four minutes of step testing with cadence 20 steps/min (ExHR4 ) , Heart Rate at Six minutes of step testing with cadence 30 steps/min (ExHR6),recovery heart rate at one minutes of rest (RcvHR1), recovery heart rate at two minutes of rest (RcvHR2) andrecovery heart rate at third minute of rest (RcvHR3),(As per the formula advocated by American College of Sports Medicine). The collected data was computed with mean, standard deviation, correlation matrix, and linear regressions for deriving linear models using SPSS.The study concluded withthe development of ten independent linear models among which model number six (M6) was found to be the best model for estimating VO2 max. of delhi youth.
