Abstract
Objective: Identify the anaerobic threshold (AnT) through blood lactate concentrations (LTDmax) and rating of perceived exertion (RPE) by the Dmax method (RPETDmax), and evaluate the correlation between these methods. Methods: Sixteen male long-distance runners participated in the study. Participants performed a gradual incremental test in leg press 45° exercise collecting blood lactate concentrations and perceived exertion. A student’s Ttest was performed to compare the intensity of exercise in which the LTDmax and RPETDmax were found, and a Pearson test was applied to verify the correlation and intraclass correlation coefficient (ICC). Results: No significant difference was found between the LTDmax and RPETDmax (p<0.05). In addition, a strong correlation (r=0.73) and high ICC (0.822) were observed between them. Conclusions: For the sample studied, it was possible to determine the AnT through the kinetics of RPE.
