Impacts of a Combined Berry Extract Supplement on Vascular Function and Oxygen Utility Capacity in Young Adults

Impacts of a Combined Berry Extract Supplement on Endothelial Function, Blood Pressure, Oxygen Utility Capacity, and Fatigue Index in Healthy Young Adults

Endothelial function was measured using flow-mediated dilation in percents (%). A higher value represents a better outcome. Scale range for endothelial function is approximately 8-12% for healthy populations.

Systolic blood pressure was measured as millimeters of mercury (mmHg). Higher values represent a worse outcome. Scale range for systolic blood pressure is approximately 110-129 for most healthy populations.

Diastolic blood pressure was measured as millimeters of mercury (mmHg). Higher values represent a worse outcome. Scale range for systolic blood pressure is approximately 70-79 mmHg for most healthy populations.

Oxygen utility capacity was measured as tissue saturation index in percents (%). Higher values represent a better outcome. Scale range for tissue saturation index is approximately 70-100% for most healthy populations.

The Effect of Tart Cherry Juice on Fat Metabolism, Exercise Performance, and Recovery

Fat oxidation determined from gas analysis

Carbohydrate oxidation determined from gas analysis

Blood pressure assessed by continuous blood pressure monitor

Muscle pain determined by a visual analog scale (participant marks a scale from 0 to 100 mm. A score of 0 mm is "no pain". A score of 100 mm is maximal pain).

Knee extensor strength determined by isometric contraction

Measured by force production at low and high stimulation frequencies as an index of muscle damage
