The aim of this study was to extend the range of populations where the Talk Test (TT) might be used as a marker of physiologic thresholds. Eighteen highly trained cyclists underwent 2 incremental tests. One test included measurement of respiratory gas exchange to determine the ventilatory (VT) and respiratory compensation thresholds (RCTs). On a separate day, a TT was performed using the same exercise protocol. During TT, subjects read a standard paragraph at the end of each stage. The first stage at which the cyclists could not talk comfortably and could definitely not talk were referred to as the equivocal (EQ) and the negative stages (NEG), respectively. There were no significant differences in workload, heart rate, lactate, and rating of perceived exertion between VT (3.7 ± 0.4 W kg, 150 ± 10 b min, 1.6 ± 0.3 mm L, and 4.1 ± 1.4, respectively) vs. EQ (3.6 ± 0.4 W kg, 148 ± 12 b min, 1.3 ± 0.5 mm L, and 3.8 ± 1.2, respectively) and RCT (5.3 ± 0.4 W kg, 177 ± 7 b min, 4.0 ± 0.9 mm L, and 7.2 ± 1.0, respectively) vs. NEG (5.3 ± 0.5 W kg, 176 ± 10 b min, 4.2 ± 1.3 mm L, and 6.8 ± 1.5, respectively). We found significant relationships (p < 0.01) between VT and EQ and RCT and NEG for workload (r = 0.86 and 0.94, respectively), heart rate (r = 0.79 and 0.92, respectively), and rating of perceived exertion (r = 0.79 and 0.88, respectively). In conclusion, the present study showed that the EQ and NEG stages of TT can be used as a simple and practical surrogate of the VT and RCT in highly trained cyclists.
本研究旨在扩大 Talk Test(TT)可用于作为生理阈值标志物的人群范围。18 名高训练水平的自行车运动员进行了 2 次递增测试。其中一次测试包括测量呼吸气体交换以确定通气(VT)和呼吸补偿阈值(RCT)。在另一天,使用相同的运动方案进行 TT。在 TT 过程中,受试者在每个阶段结束时阅读一段标准段落。运动员无法舒适地说话且肯定无法说话的第一阶段分别称为含糊阶段(EQ)和阴性阶段(NEG)。VT(3.7±0.4 W kg、150±10 b min、1.6±0.3 mm L 和 4.1±1.4)与 EQ(3.6±0.4 W kg、148±12 b min、1.3±0.5 mm L 和 3.8±1.2)和 RCT(5.3±0.4 W kg、177±7 b min、4.0±0.9 mm L 和 7.2±1.0)与 NEG(5.3±0.5 W kg、176±10 b min、4.2±1.3 mm L 和 6.8±1.5)之间的工作量、心率、血乳酸和主观感觉用力程度均无显著差异。我们发现 VT 与 EQ 以及 RCT 与 NEG 之间的工作量(r=0.86 和 0.94)、心率(r=0.79 和 0.92)和主观感觉用力程度(r=0.79 和 0.88)之间存在显著关系(p<0.01)。综上所述,本研究表明,TT 的 EQ 和 NEG 阶段可作为高度训练的自行车运动员 VT 和 RCT 的简单实用替代指标。
