Aerobic fitness can be used as a health indicator. The purpose of this study is to investigate the effect of Body Mass Index, gender, and physical activity on the aerobic fitness. Twenty females and 27 males students in range of 20 ± 1.2 years old, height 164 ± 8.95 cm, and weight 58.23 ± 9.5 kg that meet inclusion criteria were used as subject that measured in Ergonomics Laboratory Gadjah Mada University within room temperature 25-26oC and 40-50% in humidity. Four methods of indirect measurement (VO2max as an output) is used to measure aerobic fitness: nonexercise skinfold measurements and Body Mass Index, Astrand bicycle, treadmill, and the fitness index Harvard Step Test performed on different days. The results showed that gender (rs = 0.838 on the nonexercise BMI) and BMI (rs = -0.677 on the Astrand method) effect on aerobic fitness. The average value of VO2max (ml.kg-1.min in-1) is achieved from each method. For male, Astrand bicycle = 53.24 ± 7.82, treadmill = 38.43 ± 9, 05, BMI = 44.85 ± 3.45, 42.49 ± 3.38 = skinfold. For women, Astrand bicycle = 47.86 ± 8.59, ± 5.73 treadmill = 34.1, BMI = 34.25 ± 2.46, 34.63 ± 2.51 = skinfold
