从事高强度有氧运动，特别是耐力运动，与皮质醇水平升高所表明的 HPA 轴激活相关。由于传统的皮质醇评估方法（唾液、血液、尿液）仅反映相对较短的时间段，因此很难检查皮质醇水平反复短期升高是否会导致耐力运动员长期接触更高的皮质醇。头发片段分析提供了一种以回顾性方式评估长时间内累积皮质醇分泌的新方法。本研究的目的是通过检查耐力运动员的头发皮质醇水平来调查几个月内反映强化训练和竞技比赛的累积皮质醇分泌量。头发样本取自 304 名业余耐力运动员（长跑运动员、铁人三项运动员、自行车运动员）和 70 名对照者。测定最接近头皮的第一至第三个 3 厘米头发片段中的皮质醇浓度。此外，还获得了培训量的自我报告测量。与对照组相比，耐力运动员的所有三个发段都表现出更高的皮质醇水平 (p<.001)。发现第一发段的皮质醇浓度与训练量的各项指标之间呈正相关（均 p<.01）。这些数据表明，耐力运动员在强化训练和竞技比赛中反复承受的身体压力与长期接触皮质醇升高有关。这些发现可能对运动员的身心健康产生重要影响，应在未来的研究中进行调查。
Engaging in intensive aerobic exercise, specifically endurance sports, is associated with HPA axis activation indicated by elevated cortisol levels. Whether the repeated short-term elevations in cortisol levels result in higher long-term cortisol exposure of endurance athletes has been difficult to examine since traditional methods of cortisol assessments (saliva, blood, urine) reflect only relatively short time periods. Hair segment analysis provides a new method to assess cumulative cortisol secretion over prolonged time periods in a retrospective fashion. The aim of this study was to investigate cumulative cortisol secretion over several months reflecting intensive training and competitive races by examining hair cortisol levels of endurance athletes. Hair samples were obtained from 304 amateur endurance athletes (long-distance runners, triathletes, cyclists) and 70 controls. Cortisol concentrations were determined in the first to third 3-cm hair segments most proximal to the scalp. In addition, self-report measures of training volume were obtained. Endurance athletes exhibited higher cortisol levels in all three hair segments compared to controls (p<.001). Positive correlations between the cortisol concentration in the first hair segment and each indicator of training volume were found (all p<.01). These data suggest that repeated physical stress of intensive training and competitive races among endurance athletes is associated with elevated cortisol exposure over prolonged periods of time. These findings may have important implications with regard to somatic and mental health of athletes which should be investigated in future research.
