Background: Fitness is an important component of optimal physical activity and to determine one's fitness can be determined through cardiorespiratory fitness (CRF), one of which is by knowing the VO2max value. VO2max measurements can be carried out directly in the laboratory and indirectly in the field using the non-exercise fitness assessment (NEFA) and the sub-maximal methods. So, the purpose of this study is to find out and compare the measurement results directly in the laboratory and indirectly in the field. Methods: This research is a comparative descriptive study that aims to provide results from VO2max measurements with direct tests in the laboratory and indirect tests in the field. A sampling of this study used purposive sampling with the subjects of this study totaling 8 participants. Results: The results of this study stated that the VO2max results of the non-exercise fitness assessment (NEFA) method with HRrest and without HRrest had no significant difference with a P value > 0.05. Then the 6 Minute Walking Test (6MWT) with laboratory tests revealed that there was a significant difference and the 3 Minute Step Test (3MST) with laboratory tests also had significant differences with a P value < 0.05. Conclusion: The results of the analysis of the data obtained from this study, indicate that the similarity of the modified non-exercise fitness assessment (NEFA) method with and without resting heart rate (HRrest) was found to accurately predict VO2max in healthy adults because the measurement results are not far from the results laboratory test measurements. The non-exercise fitness assessment (NEFA) equation with and without resting heart rate (HRrest) provides a cost-effective method for measuring cardiorespiratory fitness. Meanwhile, the sub-maximal 6 Minute Walking Test (6MWT) and 3 Minute Step Test (3MST) methods do not have measurement results close to those of laboratory measurements, so they can not accurately predict VO2max in healthy adults.
