本研究的目的是确定运动持续时间对超耐力运动引起的唾液应激标志物变化的影响。这项研究是在2个超耐力运动测试中开发的：Ultra-trail Serra de Tramuntana（UTST），104公里的超级马拉松比赛（n = 64）和25公里的Cabrera开放水域比赛（COWR）（n = 43）。COWR的参与者以3 km/h（3 K组）或2.5 km /h（2.5K组）的恒定速度完成了25 km。在运动前后采集唾液样本。唾液流速以及皮质醇，睾酮，C-反应蛋白（CRP）和免疫球蛋白A（伊加）水平进行了测量。唾液流速在UTST后降低，但在COWR后增加。UTST诱导皮质醇和CRP水平显著升高，睾酮和伊加水平降低。此外，运动员完成运动所需的时间与唾液皮质醇的变化呈负相关。COWR后，唾液皮质醇水平的增加在3 K组中观察到高于2.5K组。运动降低睾酮和伊加水平的显着效果在两组中观察到。在COWR期间未观察到CRP水平的变化。总之，完成超耐力运动的时间越短，皮质醇的增加越多。然而，没有发现完成运动的时间和睾酮，CRP和伊加水平的变化之间的关系。
The aim of the study was to determine the influence of the exercise duration on the changes in salivary stress markers in response to ultra-endurance exercises. The study was developed in 2 ultra-endurance exercise tests: the Ultra-trail Serra de Tramuntana (UTST), a 104 km ultra-marathon competition (n = 64) and the 25 km Cabrera Open Water Race (COWR) (n = 43). Participants in the COWR completed the 25 km at a constant pace of 3 km/h (3K group) or 2.5 km /h (2.5K group). Saliva samples were taken before and after the exercises. Salivary flow rate as well as cortisol, testosterone, C-reactive protein (CRP), and immunoglobulin A (IgA) levels were measured. Salivary flow rate decreased after the UTST but increased after the COWR. The UTST induced significant increases in cortisol and CRP levels and decreases in testosterone and IgA levels. Furthermore, a negative correlation was found between the time the athletes took to complete the exercise and the changes in salivary cortisol. After the COWR, higher increases in salivary cortisol levels were observed in the 3K group than in the 2.5K group. A significant effect of exercise decreasing testosterone and IgA levels was observed in both groups. No changes in the CRP levels were observed during the COWR. In conclusion, shorter times to complete the ultra-endurance exercise were associated with higher increases in cortisol. However, no relationships were found between the time to complete the exercises and the changes in testosterone, CRP, and IgA levels.
