The evaluation of fitness levels play an important role and strongly associated with health, physical condition, motor activity, and quality of life. Fitness level indicators can be obtained by measuring maximum oxygen uptake (VO2max). The measurement of VO2max basically can be carried out directly or indirectly. 1-mile and 2000-meter jogging are generally used as one of the methods in determining VO2max. The research aims to develop a regression model to predict VO2max in 1-mile and 2000-meter jogging. Thirty-three male university students (age = 18,58 ± 0,58 y, weight = 57,92 ± 6,02, kg, height = 166,07 ± 5,30 cm, heart rate exercise = 192,48 ± 5,36 beat/minute) participated in this study. Each of them was actively performed physical activities 3-5 times per week. All participants performed both direct and indirect measurements separately with a 4 x24 hours gap after the first test. The indirect measurement of VO2max used 1-mile and 2000-meter, was exercised in two stages, while the direct measurement of VO2max applied Astrand protocol by jogging on treadmills for 7 minutes. The research found that indirect tests using the 1-mile and 2000-meter running protocols are strong predictors of predicting fitness through VO2max measurements and there is no difference witnessed between the calculation result of the formula of the indirect and direct test. The SEE of the two different measurement mentioned were 0,001 (ml.kg-1..min-1). Average discrepancy of standard deviation between VO2max and 1-mile and 2000-meter jogging was 0,8 (0,47 ml.kg-1..min-1) and 0,53 (-0,41 ml.kg-1..min-1). The formula of 1-mile and 2000-meter jogging, thus, can be used to predict VO2max accurately. © JPES.
