Outside杂志中一篇文章讲了咖啡因和咖啡的区别。啰啰嗦嗦半天其实也没啥结论。不过文章中倒是有一些信息还挺有用的。 根据研究表明每千克体重摄取3-6毫克的咖啡会对运动有帮助。如果70公斤的话，那就是210毫克到420毫克。基本上星巴克的大杯咖啡需要2杯以上了。 下次比赛前可以试试。 奥运会的咖啡因标准是差不多4-5杯以内都没事。最佳饮用咖啡因的时间是运动前30-60分钟。 The specialists at Memorial Hermann | Rockets Sports Medicine Institute believes the optimum time to consume caffeine is 30 to 60 minutes prior to a sports activity and the optimum amount before endurance events is two to three cups of regular coffee. Caffeine can increase performance in endurance sports, but just like overtraining for a sport, too much of a good thing can actually hurt their performance. https://memorialhermann.org/services/specialties/rockets-sports-medicine-institute/sports-nutrition/caffeine-and-athletic-performance#:~:text=Calculating%20Caffeine%20Amounts&text=The%20acceptable%20caffeine%20limit%20for,the%20substance%20is%20considered%20illegal.
