Clinical Trial Summary

Carnosine is a dipeptide synthesized in the body from β-alanine and L-histidine. It was originally discovered in skeletal muscle where it is present in larger amounts than in other tissues, but it is also found in high concentrations in the brain, heart, and gastrointestinal tissues of humans. Although its physiological role has not been completely understood yet, carnosine is a non-enzymatic free-radical scavenger and a natural antioxidant and has anti-inflammatory and neuroprotective properties.

The hypothesis of this research is that the consumption of carnosine supplements in the form of capsules, as well as chicken meat enriched with carnosine (functional food) has a beneficial effect on vascular reactivity measured in different vascular basins, and the lipid profile with a positive effect on the reduction of oxidative stress and inflammatory response in healthy sedentary people. subjects and active athletes measured in different vascular basins.

The main goal of this study is to investigate the influence of carnosine supplement consumption (in the form of capsules and functional food) on vascular and endothelial function in a population of healthy young subjects and active athletes.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Microvascular endothelial function	Cutaneous microvascular blood flow will be measured by Laser Doppler Flowmetry in response to vascular occlusion (post occlusive reactive hyperaemia - PORH), in response to iontophoresis of acetylcholine (ACh) and local thermal hyperemia (LTH).	3 weeks
Primary	Macrovascular endothelial function	Measurement of flow mediated dilation (FMD) of brachial artery using ultrasound.	3 weeks
Primary	Cerebrovascular reactivity	Measurement of cerebrovascular blood flow using transcranial color Doppler (TCD).	3 weeks
Secondary	Lipid profile	Measurement of plasma cholesterol, HDL cholesterol, LDL cholesterol and triglycerides level.	3 weeks
Secondary	Oxidative stress status	Measurement of Thiobarbituric Acid Reactive Substances (TBARS).	3 weeks
Secondary	Systemic hemodynamics	Non-invasive assessment of systemic hemodynamics using impedance cardiography (CardioScreen 2000) - SV Stroke Volume (mL).	3 weeks
Secondary	Serum Pro- and Anti-Inflammatory Cytokines, Chemokines, Growth Factors and Soluble Cell Adhesion Molecules Protein Concentration	Measurement of serum protein concentration (pg/mL) of various pro- and anti-inflammatory cytokines, chemokines, growth factors and soluble cell adhesion molecules by kits and panels for multiplex protein quantitation using the Luminex 200 instrument platform.	3 weeks
Secondary	Body composition	Body composition and body fluid status measurement by a four-terminal portable impedance analyzer. Based on the value of skin resistance (Ohm) empirically derived formulas (the original manufacturer's software) will be used to calculate the estimated Fat Free Mass (FFM kg) and Fat (Fat Mass kg).	3 weeks
Secondary	Body fluid status	Body fluid status measurement by a four-terminal portable impedance analyzer. Based on the value of skin resistance (Ohm) empirically derived formulas (the original manufacturer's software) will be used to calculate the estimated Total Body Water (TBW L), Extracellular Water (ECW L), Intracellular Water (ICW L), Plasma Fluid (PF L) and Interstitial Fluid (IF L).	3 weeks
Secondary	Oxidative stress status	Measurement of Ferric-Reducing Ability of Plasma (FRAP).	3 weeks
Secondary	Oxidative stress status	Measurement of enzyme activity assay of glutathione peroxidase (GPx).	3 weeks
Secondary	Systemic hemodynamics	Non-invasive assessment of systemic hemodynamics using impedance cardiography (CardioScreen 2000) - CO Cardiac Output (L/min).	3 weeks
Secondary	Systemic hemodynamics	Non-invasive assessment of systemic hemodynamics using impedance cardiography (CardioScreen 2000) - SVRI Systemic Vascular Resistance Index (dyn.s.cm-5 m2).	3 weeks
