Formulation of predict equation the Vo2max based in information independent of physical exercise

Abstract

This work presents a method capable of predicting the absolute and relative consumption of oxygen, based on physiological information about the individual without performing physical activity. At first, it is described the motivation that led to this work, the general principles of the physical tests and the techniques used for measuring and/or predicting the VO2max in 30 college students apparently healthy, with ages ranging between 20 to 30 years old (23,4 years old ± 3,18). Making use of this information, it is proposed an empirical equation to predict the VO2max, based on the high coefficient of correlation that exists between oxygen consumption by time unit and the cardiac frequency r = 0,9148. It is demonstrated through preliminary tests that the proposed model shows a reasonable index of correctness when directly compared with the results obtained in laboratory using gas analyzer, with a percentage error lower than 6%. The use of this model gives us a useful estimate, with reasonable efficacy, for a possible classification of the degree of cardiorespiratory capacity of large groups of people.
