After the Rotterdam Marathon on 21 April 1991 (ambient temperature 5.8 degrees C, relative humidity 74%, wind velocity 5 m s-1) data from 66 athletes were analysed for information concerning total recovery and recovery from pain, stiffness, loss of appetite, sleep disturbance and fatigue. The pulse rate, body weight and temperature were measured. The athletes were divided at random into two groups. Thirty-four athletes received an intravenous infusion of 2.5 l of a 2.5% glucose/0.45% NaCl solution. Thirty-two athletes received a placebo infusion of 100 ml 0.9% NaCl. Recovery took 9.2 days in the placebo group and 10.2 days in the infusion group. All athletes had pain and/or stiffness after the marathon. The immediate replacement of 2.5 l of fluid had no significant influence on the rate of total recovery, the number of days with pain or stiffness, the appetite, sleep or fatigue. On the first day after the marathon the pulse rate was increased. The rectal temperature was not affected. The athletes were also divided into fast and slow runners without regard to fluid replacement. Fast runners (those running the race in less than 2 h 55 min) needed more time to recover than slower runners and pain and/or stiffness lasted longer in the fast group. Athletes who equalled or improved their best previous results also needed more time to recover than athletes who did not, although there were no significant differences in pain and stiffness. Athletes did not benefit from immediate fluid replacement after running the 1991 Rotterdam Marathon.
1991年4月21日鹿特丹马拉松赛后（环境温度5.8摄氏度，相对湿度74%，风速5米/秒），对66名运动员的数据进行了分析，以获取有关完全恢复以及从疼痛、僵硬、食欲不振、睡眠障碍和疲劳中恢复的信息。测量了脉搏率、体重和体温。运动员被随机分为两组。34名运动员接受了静脉输注2.5升2.5%葡萄糖/0.45%氯化钠溶液。32名运动员接受了100毫升0.9%氯化钠的安慰剂输注。安慰剂组的恢复时间为9.2天，输注组为10.2天。所有运动员在马拉松赛后都有疼痛和/或僵硬症状。立即补充2.5升液体对完全恢复的速度、疼痛或僵硬的天数、食欲、睡眠或疲劳没有显著影响。马拉松赛后第一天脉搏率升高。直肠温度未受影响。运动员还被分为快跑者和慢跑者，而不考虑液体补充情况。快跑者（比赛用时少于2小时55分钟者）比慢跑者需要更多时间来恢复，并且快跑组的疼痛和/或僵硬持续时间更长。达到或提高了之前最佳成绩的运动员也比未达到的运动员需要更多时间来恢复，尽管在疼痛和僵硬方面没有显著差异。1991年鹿特丹马拉松赛后，运动员并未从立即补充液体中受益。
