N-3 Polyunsaturated Fatty Acids Enriched Chicken Meet and Cardiovascular Function
Study Details
Study Description
Brief Summary
Evidence from multiple experimental, epidemiological, and clinical studies indicate that n-3 polyunsaturated fatty acids (n-3 PUFAs) may exert their cardiovascular (CV) protective effect, at least in part, by improving vascular endothelium-dependent function. Previously, the investigators demonstrated the significant beneficiary effect of consumption of n-3 PUFA-enriched hen eggs on microvascular endothelium-dependent reactivity, even in young healthy individuals.
The hypothesis of this research is that the consumption of n-3 PUFAs in the form of functionally enriched chicken meet has a beneficial effect on vascular reactivity measured in different vascular beds, and the lipid profile with a positive effect on the reduction of oxidative stress and inflammatory response in healthy sedentary individuals.
The main goal of this study is to investigate the influence of n-3 PUFAs functionally enriched chicken meet on vascular and endothelial function in a population of healthy young subjects and active athletes.

Outcome Measures
Primary Outcome Measures
- Microvascular endothelial function [3 weeks]
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).
- Macrovascular endothelial function [3 weeks]
Measurement of flow mediated dilation (FMD) of brachial artery using ultrasound.
- Cerebrovascular reactivity [3 weeks]
Measurement of cerebrovascular blood flow using transcranial color Doppler (TCD).
Secondary Outcome Measures
- Lipid profile [3 weeks]
Measurement of plasma cholesterol, HDL cholesterol, LDL cholesterol and triglycerides level.
- Oxidative stress status [3 weeks]
Measurement of Thiobarbituric Acid Reactive Substances (TBARS).
- Systemic hemodynamics [3 weeks]
Non-invasive assessment of systemic hemodynamics using impedance cardiography (CardioScreen 2000) - SV Stroke Volume (mL), CO Cardiac Output (L/min) and SVRI Systemic Vascular Resistance Index (dyn.s.cm-5 m2).
- Serum Pro- and Anti-Inflammatory Cytokines, Chemokines, Growth Factors and Soluble Cell Adhesion Molecules Protein Concentration [3 weeks]
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.
- Body composition [3 weeks]
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).
- Body fluid status [3 weeks]
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).
- Oxidative stress status [3 weeks]
Measurement of Ferric-Reducing Ability of Plasma (FRAP).
- Oxidative stress status [3 weeks]
Measurement of enzyme activity assay of glutathione peroxidase (GPx).
