An attempt has been made to evolve some simple multiple linear regression equations for the prediction of VO2 max from body weight, time for 3.2 km run and exercise dyspnoeic index ( DIstd Ex%). The predictor variables have been selected by examining the product moment correlations of body weight, relative body weight indices, time for 3.2 km run, chest expansion, height, and DIstd Ex% with VO2 max, based on data collected on 320 healthy Indian males (17-22 years). It has been observed that body weight, time for 3.2 km run and DIstd Ex% attained maximum correlations with VO2 max. Thus, two regression equations with two and three predictor variables have been established in this paper to predict VO2 max. The first regression equation yielded a multiple correlation of 0.608 (P less than 0.001) with a standard error of 0.214 1 X min-1. In this equation, body weight and time for 3.2 km run were considered as significant predictors. To increase the precision of this equation, another multiple linear regression equation based on body weight, time for 3.2 km run and DIstd Ex% as predictors has been developed. This equation yielded a multiple correlation of 0.658 (P less than 0.001) with a standard error of 0.204 1 X min-1. Applications of these regression equations will be of practical importance to biomedical scientists engaged in the development of a simple procedure for indirect assessment of VO2 max, and may serve well as preliminary screening procedures for personnel selection.

D010101	Oxygen Consumption	The rate at which oxygen is used by a tissue; microliters of oxygen STPD used per milligram of tissue per hour; the rate at which oxygen enters the blood from alveolar gas, equal in the steady state to the consumption of oxygen by tissue metabolism throughout the body.

D012044	Regression Analysis	Procedures for finding the mathematical function which best describes the relationship between a dependent variable and one or more independent variables. In linear regression (see LINEAR MODELS) the relationship is constrained to be a straight line and LEAST-SQUARES ANALYSIS is used to determine the best fit. In logistic regression (see LOGISTIC MODELS) the dependent variable is qualitative rather than continuously variable and LIKELIHOOD FUNCTIONS are used to find the best relationship. In multiple regression, the dependent variable is considered to depend on more than a single independent variable.
