In non-elite male runners (n = 8), changes in adrenal activity were monitored by measurement of salivary cortisol in samples collected at 4-mile intervals during marathon runs. These changes were compared with those in similarly timed samples collected on rest days. Immediately prior to the Cardiff marathon, at 09.00 h, mean salivary cortisol concentrations (21.5 nmol/l) were higher than those in similarly timed rest day samples (14.9 nmol/l). Cortisol concentrations increased during the marathon, and although values at 25 miles were high (79.4 nmol/l), maximum values (87.9 nmol/l) were observed in samples collected 30 min after completion of the run. Some Cardiff marathon runners also participated in the Bristol marathon (n = 4) and a non-competitive event (n = 3). The changing pattern in secretory activity was similar in all events. The easy collection of saliva without cessation of exercise is ideal for monitoring the hormonal response to exercise.
在非精英男性跑步者（n = 8）中，通过测量马拉松跑步期间每隔4英里采集的样本中的唾液皮质醇来监测肾上腺活动的变化。将这些变化与休息日采集的时间相同的样本中的变化进行比较。在加的夫马拉松赛即将开跑前的09:00，唾液皮质醇平均浓度（21.5纳摩尔/升）高于时间相同的休息日样本（14.9纳摩尔/升）。马拉松比赛期间皮质醇浓度升高，尽管25英里处的值很高（79.4纳摩尔/升），但在跑步结束后30分钟采集的样本中观察到了最大值（87.9纳摩尔/升）。一些参加加的夫马拉松赛的跑步者还参加了布里斯托尔马拉松赛（n = 4）和一项非竞争性赛事（n = 3）。所有赛事中分泌活动的变化模式相似。在不停止运动的情况下易于采集唾液，这对于监测运动的激素反应来说是理想的。
