This study examined salivary cortisol and testosterone responses to two, different high-intensity, ∼30-min cycles separated by 2 h rest before and after an 11-day intensified training period. Twelve recreationally active, healthy males completed the study. Saliva samples were collected before, immediately after and 30 min after both bouts with salivary cortisol and testosterone concentrations assessed. Compared with pre-training blunted exercise-induced salivary cortisol, testosterone and cortisol/testosterone responses to both bouts post-training were observed (P < 0.05 for all). Comparing pre- with post-training the absolute exercise-induced salivary cortisol, testosterone and cortisol/testosterone decreased from 11.1 to 3.1 and 7.0 to 4.4 nmol · L⁻¹ (cortisol), from 407 to 258 and from 473 to 274 pmol · L⁻¹ (testosterone) and from 12 to 4 and 7 to 5 (cortisol/testosterone) for the first and second bouts, respectively (P < 0.05). No differences in the pre- and post-training rating of perceived exertion (RPE) and heart rate (HR) responses during the cycles or times to fatigue were found (P > 0.05). Fatigue and Burnout scores were higher post- compared with pre-training (P < 0.05). These high-intensity exercise bouts can detect altered hormonal responses following intensified training. This test could assess an athlete's current hormonal status, reductions in salivary cortisol and testosterone responses suggestive of increased fatigue.
这项研究检测了唾液皮质醇和睾酮对两次不同的高强度、间隔 2 小时休息的反应，在 11 天强化训练期前后各进行一次。12 名有规律运动的健康男性完成了这项研究。在两次运动前后立即和 30 分钟后采集唾液样本，评估唾液皮质醇和睾酮浓度。与训练前运动诱导的唾液皮质醇减弱相比，训练后两次运动的睾酮和皮质醇/睾酮反应都有所增强（所有 P < 0.05）。与训练前相比，训练后绝对运动诱导的唾液皮质醇、睾酮和皮质醇/睾酮分别从 11.1 降至 3.1 和从 7.0 降至 4.4 nmol·L⁻¹（皮质醇），从 407 降至 258 和从 473 降至 274 pmol·L⁻¹（睾酮），从 12 降至 4 和从 7 降至 5（皮质醇/睾酮），分别用于第一和第二回合（所有 P < 0.05）。在循环或疲劳时间内，训练前后的感觉用力等级（RPE）和心率（HR）反应没有差异（P > 0.05）。与训练前相比，疲劳和倦怠评分更高（P < 0.05）。这些高强度运动回合可以检测强化训练后荷尔蒙反应的变化。该测试可以评估运动员当前的荷尔蒙状态，皮质醇和睾酮反应的降低表明疲劳增加。
