摘要

目的:通过血乳酸浓度(LTDmax)和感知消耗等级(RPETDmax)测定无氧阈值(AnT)，并评价两种方法之间的相关性。方法:选取16名男性长跑运动员为研究对象。参与者在腿部按压45°运动中进行渐进式测试，收集血乳酸浓度和感知劳累。采用student’s Ttest比较LTDmax和RPETDmax存在的运动强度，并采用Pearson检验验证相关性和类内相关系数(ICC)。结果:LTDmax与RPETDmax无显著差异(p<0.05)。此外，两者之间存在强相关(r=0.73)和高ICC(0.822)。结论:对于所研究的样品，可以通过RPE动力学来确定AnT。

PREDICCIÓN DEL UMBRAL ANAERÓBICO EN EL EJERCICIO PRENSA DE PIERNAS A 45°

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.
