As people increasingly emphasize physical fitness, accurate and effective testing methods have become a critical focus for development. Traditional testing methods often require expensive equipment and are highly inconvenient. Therefore, leveraging technology to develop convenient and accurate testing methods is the goal of this study.. Purpose: This study aims to explore the correlation between the 3-minute incremental step-in-place test (3MISP), the 3-minute step-up test, and actual maximal oxygen uptake (V̇O2max) in a preliminary investigation, evaluating the feasibility of the 3MISP. Methods: A total of 60 healthy adults (30 males and 30 females) aged 23–64 years were recruited. Participants underwent the 3-minute step-up test, the 3MISP, and a maximal oxygen uptake test. Data were collected and analyzed using Pearson correlation coefficients to determine the linear relationship between the predictedV̇O2max and the actualV̇O2max. Paired sample t-tests were conducted to compare heart rate (HR) and percentage of heart rate reserve (HRR%) differences between the 3MISP and the step-up test. Results: The data revealed that the predictedV̇O2max from the 3MISP test showed a strong correlation with the actual measuredV̇O2max (r = 0.754, p < 0.01). We attribute this to the higher exercise intensity of the 3MISP test. This indicates that the 3MISP test is a more effective method for estimatingV̇O2max compared to traditional step-up tests, providing values closer to the actualV̇O2max. Conclusion: In terms of exercise intensity and formula correlation, the 3MISP test significantly outperforms the Step-up test. Its method and theV̇O2max estimation formula demonstrate rationality, making it a simple and effective tool for cardiorespiratory fitness assessment. It is well-suited for future promotion in home testing to enhance health management and physical fitness. |
