Influence of Coffeeberry Ingestion on Soccer Skill Performance

Study Overview
=================
Brief Summary
-----------------
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).

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Dribbling speed | m/sec, increase would be better. Simulated match in an indoor gym with pre-set targets. | During 3.5 hours post consumption | 
| Dribbling precision | Meters, more accuracy would be better. Simulated match in an indoor gym against pre-set targets. | 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. | 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. | 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. | During 3.5 hours post consumption | 
| Shooting speed | Milliseconds, faster would be better. Simulated match in an indoor gym against pre-set targets. | During 3.5 hours post consumption | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Sprint speed | m/sec, increase would be better. In indoor gym with marked course. | During 3.5 hours post consumption | 
| High-intensity endurance running capacity | Run time to volitional fatigue in min, increase would be better. In indoor gym with marked course. | During 3.5 hours post consumption |
