The bleep test has long been used to predict maximal oxygen uptake (VO2max) in Indonesian athletes. However, the results of these examinations are not as good as the results reported abroad. This research was conducted to obtain a correction formula that can provide results closer to the gold standard VO2max examination results. This cross-sectional study recruited 190 subjects. Twelve subjects were excluded because they did not follow the whole study. All subjects underwent a physical examination: vital signs, posture, leg length, and laboratory tests: treadmill test, pre-post treadmill lactic acid, spirometry, a maximum pulse, and field examinations: Bleep test, temperature, room humidity. The data obtained were analyzed according to the proper method using SPSS. The results of the analysis obtained a new predictive modeling formula, namely the Ruli formula: VO2max = 49.795 + 0.238 (Total Shuttle) + (-0.173) (BW) + (-0.086) (HRmax Field) + 0.229 (Field Temp). Internal validity and reliability tests using Bland-Altman show that this formula is quite good and can be used. However, an external validity test is still needed before this formula can be widely used in male junior athletes.
