This study of soccer skill performance has three objectives:
PepsiCo Global R&D is the lead sponsor of 101 studies on the registry; 7 are open to participants now.
Counted across the registry records on this site, refreshed daily.
Exclusion Criteria:
300 ml drink containing 300 mg coffeeberry extract
Other: Beverage
300 ml drink (0 mg coffeeberry extract, 0 mg caffeine)
Other: Beverage
Free from added carbohydrates (contain 1g CHO only) and electrolytes are absent.
Dribbling speed
m/sec, increase would be better. Simulated soccer match in an indoor gym with pre-set targets.
Time frame: 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.
Time frame: 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.
Time frame: 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.
Time frame: 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.
Time frame: Change from pre-dose baseline through end of match 3.5 hours post consumption at multiple intervals each half of match
Blood analyte: Chlorogenic acid (CGA)
mmol/L to evaluate primary outcomes. n.a. for placebo. Capillary blood draw for frozen plasma analysis
Time frame: Pre-dose baseline, 60 minutes post-dose, half-time, and end of match (3.5 hours)
Blood analyte: Caffeine metabolites
ug/ml, to evaluate primary outcomes. n.a. for placebo. Capillary blood draw for frozen plasma analysis
Time frame: Pre-dose baseline, 60 minutes post-dose, half-time, and end of match (3.5 hours)
Blood analyte: Glucose
mmol/L, more regulated would be better. Capillary blood draw for frozen plasma analysis
Time frame: Pre-dose baseline, 60 minutes post-dose, half-time, and end of match (3.5 hours)
Blood analyte: Lactate
mmol/L, lower (delayed rise) would be better. Capillary blood draw for frozen plasma analysis
Time frame: Pre-dose baseline, 60 minutes post-dose, half-time, and end of match (3.5 hours)
Rating of perceived exertion (RPE)
By Borg scale, rated 6 to 20, very very light to very very hard. Lower values would be better
Time frame: Half-time and end of match (3.5 hours)
Activation-deactivation (feelings or mood)
Checklist of 20 feelings using a 4 point scale from definitely do feel to definitely don't feel. More relaxed feelings or in a better mood would be better.
Time frame: Pre-dose baseline, 60 minutes post-dose, half-time, and end of match (3.5 hours)
Mental energy
Visual Analog Scale (VAS), vertical marking on 100 mm horizontal line. Higher energy would be better
Time frame: Pre-dose baseline, 60 minutes post-dose, half-time, and end of match (3.5 hours)
Physical energy
Visual Analog Scale (VAS), vertical marking on 100 mm horizontal line. Higher energy would be better
Time frame: Pre-dose baseline, 60 minutes post-dose, half-time, and end of match (3.5 hours)
Gut comfort
Visual Analog Scale (VAS), vertical marking on 100 mm horizontal line. No or less nausea, fullness or bloating would be better
Time frame: Pre-dose baseline, 60 minutes post-dose, half-time, and end of match (3.5 hours)
Heart rate
By electronic reading. Lower would be better.
Time frame: Continuous from pre-dose baseline through end of match (3.5 hours)
Hydration status
Urine osmolality in mOsm/kg change in concentration pre- vs. post-exercise
Time frame: Pre-dose baseline and end of match (3.5 hours)
