The theory of challenge and threat states in athletes (TCTSA) proposes psychological antecedents will predict psychological and cardiovascular responses to stress. The present study investigated this theory in two contextually different stress tasks.
78 males completed a computerised competition and a public speaking task. Cardiovascular activity was measured with impedance cardiography and a blood pressure monitor. Challenge and threat antecedents, indicators of challenge and threat and emotions were assessed pre- and post-tasks.
Both tasks induced significant perturbations in cardiovascular activity and were perceived as highly challenging. Reported perceived threat was higher in the public speaking task compared to the competition task. Associations between the proposed antecedents, self-report and cardiovascular indices of challenge and threat and emotions support the TCTSA for the competition task, but less so for the public speaking task.
The TCTSA is supported during competitive stress, however during social stress there is dissociation between self-report appraisals and cardiovascular reactivity.
运动员的挑战与威胁理论（TCTSA）提出，心理前因将预测应对压力时的心理和心血管反应。本研究在两个不同情境的应激任务中对此理论进行了探讨。
78 名男性完成了计算机竞赛和公开演讲任务。心血管活动通过阻抗心动描记法和血压监测仪进行测量。在任务前后评估了挑战与威胁的前因、挑战与威胁的指标以及情绪。
两个任务都引起了心血管活动的显著变化，被认为极具挑战性。与竞赛任务相比，公开演讲任务中报告的感知威胁更高。所提出的前因、自我报告与心血管挑战和威胁指标以及情绪之间的关联支持了竞争任务中的 TCTSA，但在公开演讲任务中则不太支持。
在竞争压力下，TCTSA 得到支持，但在社交压力下，自我报告评估与心血管反应之间存在脱节。
