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