Study Details

Study Description

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).

Arms and Interventions

Arm Intervention/Treatment
Experimental: Coffeeberry beverage

300 mg Coffeeberry extract in 300 ml beverage

Dietary Supplement: Coffeeberry beverage
One exposure of 300 mg coffeeberry extract in a 300 ml flavored still beverage prior to exercise session

Placebo Comparator: Color and flavor matched beverage

0 mg Coffeeberry extract in 300 ml flavor and color-matched beverage

Other: Comparator beverage
One 300 ml still beverage, color and flavor matched to experimental beverage prior to exercise session

Outcome Measures

Primary Outcome Measures

  1. Dribbling speed [During 3.5 hours post consumption]

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

  2. Dribbling precision [During 3.5 hours post consumption]

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

  3. Passing accuracy [During 3.5 hours post consumption]

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

  4. Passing speed by Time [During 3.5 hours post consumption]

    km/h, increased would be better. Simulated match in an indoor gym against pre-set targets.

  5. Shooting accuracy [During 3.5 hours post consumption]

    More shots on target would be better. Simulated match in an indoor gym against pre-set targets.

  6. Shooting speed [During 3.5 hours post consumption]

    Milliseconds, faster would be better. Simulated match in an indoor gym against pre-set targets.

Secondary Outcome Measures

  1. Sprint speed [During 3.5 hours post consumption]

    m/sec, increase would be better. In indoor gym with marked course.

  2. High-intensity endurance running capacity [During 3.5 hours post consumption]

    Run time to volitional fatigue in min, increase would be better. In indoor gym with marked course.

Other Outcome Measures

  1. Blood analyte concentration: Capillary glucose [During 3.5 hours post consumption]

    (mmol/L), more regulated would be better

  2. Blood analyte concentration: Capillary lactate [During 3.5 hours post consumption]

    (mmol/L), lower (delayed rise) would be better

  3. Blood analyte concentration: Serum chlorogenic acid [During 3.5 hours post consumption]

    (mmol/L), n.a. for placebo, introduced to evaluate primary outcomes

  4. Blood analyte concentration: Serum caffeine [During 3.5 hours post consumption]

    (ug/mL), n.a. for placebo, Introduced to evaluate primary outcomes

  5. Rate of Perceived Exertion (RPE) [During 3.5 hours post consumption]

    By Borg scale, rated 6-20, lower values would be better

  6. Activation/Deactivation (feelings and mood) [During 3.5 hours post consumption]

    Checklist of feelings using a 4 point scale from definitely do to definitely don't feel, more relaxed and better mood would be better

  7. Mental energy [During 3.5 hours post consumption]

    By Visual Analog Scale (VAS) vertical marking on 100 mm horizontal line, higher energy would be better

  8. Physical energy [During 3.5 hours post consumption]

    By Visual Analog Scale (VAS) vertical marking on 100 mm horizontal line, higher energy would be better

  9. Heart rate [During 3.5 hours post consumption]

    By electronic reading, lower would be better

  10. Gut comfort [During 3.5 hours post consumption]

    By Visual Analog Scale (VAS) vertical marking on 100 mm horizontal scale, no or less nausa, fullness or bloating would be better

  11. Hydration status [During 3.5 hours post consumption]

    Urine osmolality in mOsm/kg, comparing pre- vs. post-exercise concentration
