An extract from whole Coffea arabica coffee cherry improves time trial performance, but not muscle glycogen resynthesis, in trained cyclists

BACKGROUND: coffee cherry extract concentrated in caffeine and polyphenols would increase exercise performance and muscle glycogen resynthesis. METHODS: carbohydrate and a second time trial (TT2) was performed the following morning. Blood samples were collected throughout, and muscle biopsies were collected immediately after TT1 (0 h), and at 4 and 24 h. RESULTS: < 0.001). CONCLUSIONS: Registered with clinicaltrials.gov on 10/01/2022 as NCT05404841 (URL: https://clinicaltrials.gov/study/NCT05404841).
