Overview

Therefore, the aim of our project will be to assess the impact of omega-3 fatty acid on the neuromuscular system (muscle tensomyography- TMG), the composition and fluidity of erythrocyte cell membranes, the lipid profile and the antioxidant status of the blood.

The ability of skeletal muscles to generate force and resist fatigue is essential for athletic performance. Training adaptations within the neuromuscular system and skeletal muscles modulate the muscles' ability to produce force and resistance to fatigue. Much research has been conducted to determine the effects of dietary supplements on skeletal muscle adaptation to strength training (e.g., protein supplementation) and methods to support endurance performance (e.g., carbohydrate loading). However, limited research has been conducted to date on the effects of dietary supplements on the neuromuscular system.The research will focus on the effect of 4 and 8 weeks of supplementation with high doses of omega 3 fatty acids on the level of omega 3/omega6 fatty acids, the level of TRANS fatty acids and AA (arachidonic acid) fatty acid using a mixed diet. Additionally, we will examine the effect of this supplementation on the neuromuscular system (muscle tensomyography -TMG), the composition and fluidity of erythrocyte cell membranes, the lipid profile and the antioxidant status of the blood. The research will use innovative assumptions - high doses of omega 3 fatty acids. Additionally, a new laboratory tool will be used to assess the level of individual fatty acids (omega 3, omega 6) in the blood, the level of which shows or excludes latent inflammation in the body.

Outcomes

Primary Outcomes

Omega 3 index

The Omega-3 Index (%) determines the content of EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) relative to total fatty acids in erythrocyte membranes. It is expressed as a percentage and reflects long-term fatty acid intake. Unit of Measure: %

Time frame: 4-weeks

Secondary Outcomes

Tensiomyography (TMG) Parameters

2a. Maximal Radial Displacement (Dm) Unit of Measure: mm 2b. Contraction Time (Tc) Unit of Measure: ms 2c. Delay Time (Td) Unit of Measure: ms 2d. Sustain Time (Ts) Unit of Measure: ms 2e. Half-Relaxation Time (Tr) Unit of Measure: ms Description: Muscle contractile properties assessed using tensiomyography (TMG-BMC system).

Time frame: 4-weeks

Corsi Block-Tapping Test - Unweighted Block Span

Description: Maximum correctly reproduced sequence length in Corsi Block-Tapping Test. Unit of Measure: blocks
