There are numerous anecdotal reports relating infection to deterioration in sporting performance. Unexplained failures by top sportsmen are often attributed to recent or current infections. We have carried out a prospective investigation to determine the effect of viral infections on the performance of a group of 68 elite track and field athletes. Athletes were monitored for evidence of viral infection during winter training and their form was assessed subjectively and also semi-objectively by analogue scale questionnaires. Static elevated titres of neutralising antibody to Coxsackie B 1-5 were present in 54% of the athletes and 79% had serological evidence of past viral infection. The raised titres did not relate to poor performance. There was no evidence that loss of form was related to subclinical infection. Elevated antibody levels to Coxsackie B and other common viruses should be interpreted with great caution when assessing athletes complaining of poor performance.
有大量轶事报道将感染与运动成绩下降联系起来。顶级运动员出现的不明原因成绩下滑往往被归咎于近期或当前的感染。我们进行了一项前瞻性调查，以确定病毒感染对一组68名优秀田径运动员成绩的影响。在冬季训练期间对运动员进行病毒感染迹象监测，并通过模拟量表问卷对他们的状态进行主观和半客观评估。54%的运动员存在针对柯萨奇B1 - 5型病毒的静态中和抗体滴度升高，79%的运动员有既往病毒感染的血清学证据。抗体滴度升高与成绩不佳无关。没有证据表明状态下滑与亚临床感染有关。在评估抱怨成绩不佳的运动员时，对于柯萨奇B病毒和其他常见病毒抗体水平升高的情况应极其谨慎地解读。
