Abstract

AIM

The aim of this study was to investigate the urine cortisol (F) and cortisone (E) relation, having a well-defined water intake.

METHODS

Urine specimens were collected from 10 male trained cyclists (19+/-1 year, 70+/-4 kg, 179+/-4 cm), at rest just before the test (pre-exe) and until 45 min after the cycle ergometer exercise test (45 min at 50-60% VO2max) (post-exe) in the morning. This investigation measured the diuresis in the pre-exe and post-exe after each athlete had drunk 1 L of water from waking-up, after bladder emptying, to the start of the test (pre-exe) and 1 L during the 45 min after the exercise (post-exe).

RESULTS

Urinary F and E concentrations demonstrated a significant decrease comparing pre-exe with post-exe (177+/-134 vs 64+/-21 and 706+/-475 vs 372+/-178 nmol.L(-1) respectively, p < 0.05). This significant decrease was verified when diuresis and urinary creatinine were taken into account and the ratio measured.

CONCLUSION

One litre of water intake after exercise seemed to have no effect on urine F and E excretion. Moreover the urine F/E ratio was not statistically different comparing pre-exe with post-exe.

摘要

目的

本研究旨在探讨在明确规定水摄入量的情况下，尿皮质醇（F）和可的松（E）之间的关系。

方法

收集10名男性训练有素的自行车运动员（年龄19±1岁，体重70±4千克，身高179±4厘米）的尿液样本，样本采集时间为早晨，在测试前（运动前）休息时以及在自行车测力计运动测试后45分钟（以最大摄氧量的50 - 60%进行45分钟运动）（运动后）。本研究测量了每位运动员在从醒来膀胱排空后到测试开始（运动前）饮用1升水后的排尿量，以及运动后45分钟内饮用1升水后的排尿量。
