This study addressed whether lifetime stressor exposure was associated with psychophysiological reactivity and habituation to a novel laboratory-based stressor. Eighty-six participants (M _age = 23.31 years, SD = 4.94) reported their exposure to lifetime non-sport and sport-specific stressors before completing two consecutive trials of the Trier Social Stress Test, while cardiovascular (i.e., heart rate) and endocrine (i.e., salivary cortisol) data were recorded. Exposure to a moderate number of lifetime non-sport and sport-specific stressors was associated with adaptive cardiovascular reactivity, whereas very low or very high stressor exposure was related to maladaptive reactivity. Moreover, experiencing a very low number of lifetime non-sport (but not sport-specific) stressors was associated with poorer habituation. In contrast, lifetime stressor severity was unrelated to cardiovascular reactivity. Finally, greater lifetime non-sport and sport-specific stressor counts were associated with blunted cortisol reactivity and poorer habituation. These results suggest that lifetime stressor exposure may influence sport performers’ acute stress responses.

本研究探讨了终生压力源暴露是否与心理生理反应和对新型实验室压力源的习惯有关。86 名参与者（M _年龄 = 23.31 岁，SD = 4.94) 报告了他们在完成两次连续的特里尔社会压力测试试验之前暴露于终生非运动和运动特定压力源，同时记录了心血管（即心率）和内分泌（即唾液皮质醇）数据。终生暴露于中等数量的非运动和运动特异性压力源与适应性心血管反应相关，而极低或极高的压力源暴露与适应不良反应相关。此外，一生中经历的非运动（但不是运动特定）压力源数量非常少与较差的习惯有关。相反，终生应激源严重程度与心血管反应性无关。最后，更大的终生非运动和运动特定压力源计数与皮质醇反应迟钝和较差的习惯有关。
