Brief Summary

This study of soccer skill performance has three objectives:

1. 1.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.
2. 2.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.
3. 3.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.

Outcome Measures

Primary Outcomes (5)

• Dribbling speed

  m/sec, increase would be better. Simulated soccer match in an indoor gym with pre-set targets.

  Change from pre-dose baseline through end of match 3.5 hours post consumption at multiple intervals each half of match

• Dribbling precision

  Meters, more accuracy would be better. Simulated soccer match in an indoor gym with pre-set targets.

  Change from pre-dose baseline through end of match 3.5 hours post consumption at multiple intervals each half of match

• Passing accuracy

  1 to 10 scale, a higher score would be better. Simulated soccer match in an indoor gym with pre-set targets.

  Change from pre-dose baseline through end of match 3.5 hours post consumption at multiple intervals each half of match.

• Passing speed

  km/h, increased passing speed would be better. Simulated soccer match in an indoor gym with pre-set targets.

  Change from pre-dose baseline through end of match 3.5 hours post consumption at multiple intervals each half of match

• Sprint speed.

  m/sec, increased sprint speed would be better. In indoor gym with marked course.

  Change from pre-dose baseline through end of match 3.5 hours post consumption at multiple intervals each half of match

Secondary Outcomes (11)

• Blood analyte: Chlorogenic acid (CGA)

  Pre-dose baseline, 60 minutes post-dose, half-time, and end of match (3.5 hours)

• Blood analyte: Caffeine metabolites

  Pre-dose baseline, 60 minutes post-dose, half-time, and end of match (3.5 hours)

• Blood analyte: Glucose

  Pre-dose baseline, 60 minutes post-dose, half-time, and end of match (3.5 hours)

• Blood analyte: Lactate

  Pre-dose baseline, 60 minutes post-dose, half-time, and end of match (3.5 hours)

• Rating of perceived exertion (RPE)

  Half-time and end of match (3.5 hours)
