This study aimed to look at the test-reliability of the estimated maximun oxygen volume (V02max), as assessed by the progressive aerobic cardiovascular resistance running test (PACER), in young adults of bothe sexes and at varied levels of physical activity. Determine whether the reliability levels are influenced by prediction formulas. Data was collected from 37 participants aged 20 to 34. The age, wieght, height, heart rate, and blood pressure of the participants were all recorded. The level of physical activity was assessed using a questionnaire, and the heart rate was measured using a POLAR H7. The PACER exam was performed twice, with a 24-72-hour delay between each time. V02max was estimated using three predictive formulae, Léger, Matsuzaka, and Fernhall, based on the number of laps and maximum speed. The interclass correlation coeficient (ICC) was used to measure relative reliability, and the standard error measured (SEM) and minimal detectable change (MDC) were used to assess absolute reliability. In the total sample excelente test-reset correlation values were found for estimating V02max (ICC=0.90-0.94), SEM (3.96-11.62), and MDC (7,90-32,21). Regarding the level of physical activity, bothe groups obtained excelente correlation values, active (ICC=0.92-0.85) and sedentary (ICA=0.79-0.89, SEM (2.74-11.75) and MDC (7,59-32,57). Considering gender, the two groups obtained for the most part excelente correlation values, men (ICC=0.87-0.92) and woman (ICC=0.70-0.81), SEM (2.04-13.62) and MDC (5,65-37,75). The V02max estimated through the PACER test shows excelente reliability values in individuals of both sexes, active and sedentary, considering the 3 predictive formulas analyzed.
