简要总结
This study of soccer skill performance has three objectives:
- Compare effects of coffeeberry (300mg) and placebo ingestion on dribbling speed and precision, passing speed and accuracy, and sprint speed during a full simulated soccer match.
- Compare effects of coffeeberry (300mg) and placebo ingestion on subjective measures (mental / physical energy and activation-deactivation (feelings or mood) during a full simulated soccer match.
- Compare effects of coffeeberry (300mg) and placebo ingestion on chlorogenic acid (CGA) and caffeine metabolites in the blood 1-hour post ingestion, and other blood metabolites (glucose/lactate) throughout the simulated soccer match.

结局指标
主要结局
Sprint speed.
时间窗: Change from pre-dose baseline through end of match 3.5 hours post consumption at multiple intervals each half of match
m/sec, increased sprint speed would be better. In indoor gym with marked course.
Passing accuracy
时间窗: Change from pre-dose baseline through end of match 3.5 hours post consumption at multiple intervals each half of match.
1 to 10 scale, a higher score would be better. Simulated soccer match in an indoor gym with pre-set targets.
Dribbling precision
时间窗: Change from pre-dose baseline through end of match 3.5 hours post consumption at multiple intervals each half of match
Meters, more accuracy would be better. Simulated soccer match in an indoor gym with pre-set targets.
Dribbling speed
时间窗: Change from pre-dose baseline through end of match 3.5 hours post consumption at multiple intervals each half of match
m/sec, increase would be better. Simulated soccer match in an indoor gym with pre-set targets.
Passing speed
时间窗: Change from pre-dose baseline through end of match 3.5 hours post consumption at multiple intervals each half of match
km/h, increased passing speed would be better. Simulated soccer match in an indoor gym with pre-set targets.
