This article focuses on changes in Ramadan during the course of the waking day in physical performance, mental performance and gastrointestinal function. Possible explanations of the changes are considered by reference to the roles of the body clock and external factors such as the environment and the individual's lifestyle. The effects of these factors upon training schedules and upon changing the times of training are then discussed in terms of physiology and biochemistry. Delaying the time of training until after sunset has advantages and disadvantages, but it is a regimen that is unlikely to be widely accepted in non-Muslim countries. It is clear that the detailed nature of the problems involved and dealing with them in a manner based upon a firm body of knowledge requires far more experimental investigation.
本文主要关注斋月期间白天在身体机能、精神表现和胃肠道功能方面的变化。通过参考生物钟的作用以及环境和个体生活方式等外部因素，对这些变化的可能原因进行了探讨。然后，从生理学和生物化学的角度讨论了这些因素对训练计划和训练时间改变的影响。将训练时间推迟到日落之后有其优缺点，但在非穆斯林国家，这种方案不太可能被广泛接受。显然，涉及的问题的详细性质以及基于坚实的知识体系来处理这些问题需要进行更多的实验研究。
