Validity of maximum consumption of oxygen and intensity prescription of aerobic training predict by 12 minute Cooper test on young sedentary adults
Abstract
Since 1918, when the first tests of maximum consumption of oxygen (VO2max) were carried out, researchers and practitioners have tried to measure the individuals’ physical aptitude, in order to classify them from a functional point of view, as well as to get parameters for an adequate exercise prescription. The aim of this study was to verify the validity of this test for the measurement of the VO2max and intensity prescription of aerobic training, according to the recommendations of the American College of Sports Medicine (2003). The sample was constituted by 11 voluntary, healthy sedentary male college students, 24 ± 1.8 years old, weight of 78.4 ± 10.82 kg, stature of 174 ± 8.2 cm and body mass index (BMI) of 26 ± 3.8 kg/m2. The ergospirometry and the 12 minute Cooper test were carried out in all individuals, with an interval of 48 to 72 hours between each test. The VO2max, the inferior and superior limits for intensity prescription of predict aerobic training by 12 minute Cooper test were on average 14.7%, 25.4%, and 8.3% lower, respectively, when compared with the ergospirometry results (p<0.05). Therefore, such test did not present good validity for the studied population.
