Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
This study aims to determine if a low dose of caffeine, in the form of a whole-fruit coffee extract also containing polyphenols, can improve exercise performance compared to a placebo condition, with a secondary objective of identifying if this supplement can improve post exercise refuelling (glycogen resynthesis).
Participants will consume either the supplement or a placebo before engaging in an exercise protocol. Muscle biopsies will then be obtained so as to measure subsequent glycogen resynthesis, with multiple blood samples being taken through the day. The following morning another biopsy will be taken before the exercise protocol will be repeated.
This research will inform us of the efficacy of caffeine and polyphenols on improving exercise performance.
