Performance losses in middle age are often attributed to biological ageing. Running-time analyses in long-distance runners aged 20-80 years (n > 500,000) show that in fact no significant performance reductions occur before the age of 54 years. Moreover, further investigations carried out in the context of the PACE project (http://www.dshs-koeln.de/en/pace) reveal that performance losses in middle age are primarily caused by unhealthy lifestyle and lack of training. The increasing number of overweight, untrained individuals indicates that current preventive efforts are insufficient. Maintaining health and performance is becoming an urgent problem in modern society and a solution to this cost-intensive problem is not yet in sight.
中年时期的体能下降通常被归因于生物衰老。对20至80岁的长跑运动员（n>500,000）进行的跑步时间分析表明，事实上在54岁之前并没有出现明显的体能下降。此外，在PACE项目（http://www.dshs-koeln.de/en/pace）中进行的进一步调查显示，中年时期的体能下降主要是由不健康的生活方式和缺乏训练导致的。超重且未经训练的个体数量不断增加，这表明目前的预防措施并不充分。在现代社会中，保持健康和体能正成为一个紧迫的问题，而解决这个成本高昂的问题的方法仍未见端倪。
