The Talk Test (TT) is a submaximal, incremental exercise test that has been shown to be useful in prescribing exercise training intensity. It is based on a subject's ability to speak comfortably during exercise. This study defined the amount of reduction in absolute workload intensity from an incremental exercise test using the TT to give appropriate absolute training intensity for cardiac rehabilitation patients.
Patients in an outpatient rehabilitation program (N = 30) performed an incremental exercise test with the TT given every 2-minute stage. Patients rated their speech comfort after reciting a standardized paragraph. Anything other than a "yes" response was considered the "equivocal" stage, while all preceding stages were "positive" stages. The last stage with the unequivocally positive ability to speak was the Last Positive (LP), and the preceding stages were (LP-1 and LP-2). Subsequently, three 20-minute steady-state training bouts were performed in random order at the absolute workload at the LP, LP-1, and LP-2 stages of the incremental test. Speech comfort, heart rate (HR), and rating of perceived exertion (RPE) were recorded every 5 minutes.
The 20-minute exercise training bout was completed fully by LP (n = 19), LP-1 (n = 28), and LP-2 (n = 30). Heart rate, RPE, and speech comfort were similar through the LP-1 and LP-2 tests, but the LP stage was markedly more difficult.
Steady-state exercise training intensity was easily and appropriately prescribed at intensity associated with the LP-1 and LP-2 stages of the TT. The LP stage may be too difficult for patients in a cardiac rehabilitation program.
谈话测试（TT）是一种次极量递增运动测试，已被证明有助于规定运动训练强度。它基于受试者在运动期间舒适交谈的能力。本研究确定了使用TT进行递增运动测试时绝对工作量强度的降低量，以便为心脏康复患者提供合适的绝对训练强度。
门诊康复项目中的患者（N = 30）进行递增运动测试，每2分钟阶段进行一次TT。患者在背诵一段标准化段落后对其言语舒适度进行评分。除“是”以外的任何回答都被视为“模棱两可”阶段，而之前的所有阶段都是“阳性”阶段。能够明确积极交谈的最后阶段是最后阳性（LP）阶段，之前的阶段是（LP - 1和LP - 2）。随后，在递增测试的LP、LP - 1和LP - 2阶段的绝对工作量下，随机顺序进行三次20分钟的稳态训练回合。每5分钟记录一次言语舒适度、心率（HR）和自觉用力程度（RPE）。
LP（n = 19）、LP - 1（n = 28）和LP - 2（n = 30）均完全完成了20分钟的运动训练回合。通过LP - 1和LP - 2测试，心率、RPE和言语舒适度相似，但LP阶段明显更困难。
在与TT的LP - 1和LP - 2阶段相关的强度下，稳态运动训练强度很容易且适当地规定。LP阶段对心脏康复项目中的患者来说可能太难了。
