Aim: Aerobic threshold is the minimum intensity and duration of exercise, which is effective in improving aerobic capacity. Studies have shown that achieving exercise goals for improving cardio-respiratory capacity requires activity at the intensity equivalent to the aerobic threshold. The aerobic threshold is the intensity needed in order to produce an adaptation that will improve someone's aerobic capacity or VO2max. The aerobic training threshold is defined as the point at which lactate begins to rise in the blood above normal resting levels. The aim of this study was to determine the aerobic threshold by means of the maximum distance method (Dmax) based on HRPC in active young men. Methodology: In a laboratory trial, 30 active young men were selected on a targeted basis as subjects and studied. The aerobic threshold of the subjects was determined by means of two methods using respiratory gas analysis as the criterion method and maximum distance model based on HRPC. Bland – Atmann plots, Pearson Correlation Coefficient and Paired Sample T-test were used for data analysis. Results: The aerobic thresholds of all of the subjects were obtained by by the means of the heart rate performance curve (HRPC) using the Maximum distance method (Dmax) method. However, supplementary results revealed that moderate agreement exist between two methods. Similarly, significant but moderate correlations observed between two models, while there was no significant difference exists between two methods. Conclusion: According to these results, it can be concluded that using the heart rate method (HR) for determining the aerobic threshold may be useful. Therefore, instead of time consuming as well as expensive methods, these simple and inexpensive methods can be used.
