To validate the traditional talk test (TTT) and an alternative talk test (ATT; using a visual analog scale) in overweight/obese (OW-OB) patients and to establish its accuracy in determining the aerobic training zones.
We recruited 19 subjects aged 34.9 ± 6.7 years, diagnosed with overweight/obesity (BMI 31.8 ± 5.7). Every subject underwent incremental cycloergometric tests for maximal oxygen consumption, and TTT in a randomized order. At the end of each stage during the TTT, each subject read out loud a 40 words text and then had to identify the comfort to talk in two modalities: TTT which consisted in answering "Yes," "I don't know," or "No" to the question Was talking comfortable?, or ATT through a 1 to 10 numeric perception scale (visual analog scale (VAS)). The magnitude of differences was interpreted in comparison to the smallest worthwhile change and was used to determine agreement.
There was an agreement between the power output at the VAS 2-3 of ATT and the power output at the ventilatory threshold 1 (VT1) (very likely equivalent; mean difference - 1.3 W, 90% confidence limit (CL) (- 8.2; 5.6), percent chances for higher/similar/lower values of 0.7/99.1/0.2%). Also, there was an agreement between the power output at the VAS 6-7 of ATT and the power output at the ventilatory threshold 2 (VT2) (very likely equivalent; mean difference 11.1 W, 90% CL (2.8; 19.2), percent chances for higher/similar/lower values of 0.0/97.6/2.4%).
ATT is a tool to determine exercise intensity and to establish aerobic training zones for exercise prescription in OW-OB patients.
验证传统谈话测试（TTT）和一种替代谈话测试（ATT；使用视觉模拟量表）在超重/肥胖（OW-OB）患者中的有效性，并确定其在确定有氧训练区域方面的准确性。
我们招募了19名年龄在34.9±6.7岁的受试者，诊断为超重/肥胖（BMI 31.8±5.7）。每位受试者以随机顺序进行递增式蹬车测力试验以测定最大摄氧量，并进行TTT。在TTT的每个阶段结束时，每位受试者大声朗读一段40个单词的文本，然后必须通过两种方式确定谈话的舒适度：TTT是对“谈话是否舒适？”这个问题回答“是”“我不知道”或“否”，或者通过1至10的数字感知量表（视觉模拟量表（VAS））进行ATT。将差异大小与最小有意义变化进行比较来解释，并用于确定一致性。
ATT的VAS 2-3时的功率输出与通气阈值1（VT1）时的功率输出之间存在一致性（非常可能等效；平均差异-1.3W，90%置信区间（CL）（-8.2；5.6），较高/相似/较低值的百分比机会为0.7/99.1/0.2%）。此外，ATT的VAS 6-7时的功率输出与通气阈值2（VT2）时的功率输出之间存在一致性（非常可能等效；平均差异11.1W，90%CL（2.8；19.2），较高/相似/较低值的百分比机会为0.0/97.6/2.4%）。
ATT是一种用于确定运动强度和为OW-OB患者制定运动处方确定有氧训练区域的工具。
