About this study
Official title: Influence of Coffeeberry Extract on Soccer Specific Skill Performance After Rest, During Simulated Soccer Match Play, and Following Fatiguing Exercise in Academy Football Players
The study of soccer skill performance has 3 objectives. Objective 1 is to compare effects of coffeeberry (300mg) and placebo ingestion on dribbling speed and precision and passing and shooting speed and accuracy compared to placebo. 30 subjects will be assessed before dosing, after a 1 hr resting absorption period, and after simulated soccer match play. Of these 30, 20 subjects will proceed to Objective 2 (45 minutes of intense simulated soccer match play) and Objective 3 (repeated sprint activity continued until volitional fatigue).

Meters, more accuracy would be better. Simulated match in an indoor gym against pre-set targets.
Measured: During 3.5 hours post consumption
Passing accuracy
1-10 scale, higher score would be better. Simulated match in an indoor gym against pre-set targets.
Measured: During 3.5 hours post consumption
Passing speed by Time
km/h, increased would be better. Simulated match in an indoor gym against pre-set targets.
Measured: During 3.5 hours post consumption
Shooting accuracy
More shots on target would be better. Simulated match in an indoor gym against pre-set targets.
Measured: During 3.5 hours post consumption
Shooting speed
Milliseconds, faster would be better. Simulated match in an indoor gym against pre-set targets.
Measured: During 3.5 hours post consumption
Secondary outcomes (2)
Sprint speed
m/sec, increase would be better. In indoor gym with marked course.
Measured: During 3.5 hours post consumption
