Effects of Tart Cherry and Aronia Extract Supplementation on Selected Physiological Parameters in Endurance-Trained Men
Sponsor: Wroclaw Medical University
Summary
This study will evaluate the effects of four weeks of oral supplementation with a double-standardized tart cherry (Prunus cerasus) and aronia (Aronia melanocarpa) extract on cardiovascular regulation and exercise performance in healthy endurance-trained men aged 40 to 75 years. In a randomized crossover design, 25 participants will receive CHG SPORT and placebo for four weeks each, separated by a four-week washout period. Assessments will include resting cardiovascular and respiratory measurements, cardiovascular and ventilatory responses to transient hypoxia, flow-mediated dilation, skin advanced glycation end products, cardiopulmonary exercise testing, 24-hour ambulatory blood pressure, and blood biomarkers. The study will determine whether CHG SPORT supplementation produces changes in selected cardiovascular and exercise-performance measures compared with placebo.

Interventions
Standardized Tart Cherry and Aronia Extract
Oral capsules containing 400 mg per capsule of a double-standardized extract of Prunus cerasus (Vistula) and Aronia melanocarpa (Michaux). The Prunus cerasus extract is standardized to a minimum of 15% polyphenols and 3% anthocyanins (DER 40:1), and the Aronia melanocarpa extract is standardized to a minimum of 50% polyphenols and 25% anthocyanins (DER 70:1). The intervention will be administered for four weeks during the active supplementation period.
Placebo
Maltodextrin-based placebo capsules visually matched to CHG SPORT capsules and supplied in identical containers. The placebo will be administered according to the same dosing schedule and for the same four-week duration as the active intervention.
