An extract from whole Coffea arabica coffee cherry improves time trial performance, but not muscle glycogen resynthesis, in trained cyclists.
Journal of the International Society of Sports Nutrition·December 31, 2026·PMID 42234539
Why it mattersThis study suggests that a low-dose caffeine–polyphenol coffee cherry extract can acutely improve high-intensity cycling performance, offering a potential ergogenic aid for athletes. The lack of effect on glycogen resynthesis indicates that any performance benefit is likely due to central or metabolic effects during exercise rather than enhanced recovery.
