3 juni 2026 uppdaterad av: Małgorzata Magdalena Michalczyk, The Jerzy Kukuczka Academy of Physical Education in Katowice
The Impact of Omega-3 Fatty Acid Supplementation on the Composition of Erythrocyte and Neuromuscular System in Athletes
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.

Detaljerad beskrivning
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.

Intervention / Behandling |
|---|---|
|
Experimentell: AL (Alpha-linolenic acid) supplementation
Participants were randomly assigned to the ALA supplementation group.
After 4 weeks of the supplementation, there was a 12-week wash-out period, after which the participants crossed over to the EPA /DHA group.
|
The supplement will be administered in a dose of 4 capsules twice a day for 4 weeks.
Daily dose will contain 3500mg ALA.
|
|
Experimentell: EPA (eicosapentaenoic acid)/DHA (docosahexaenoic acid) supplementation
Participants were randomly assigned to the EPA/DHA supplementation group.
After 4 weeks of the supplementation, there was a 12-week wash-out period, after which the participants crossed over to the ALA group.
|
The supplement will be administered in a dose of 4 capsules twice a day for 4 weeks.
Each capsule will contain 330mg EPA and 220mgDHA.

Placebo-jämförare: Placebo supplementation
Participants were randomly assigned to the Placebo group.
After 4 weeks of the supplementation, there was a 12-week wash-out period, after which they repeated the placebo supplementation.
|
The supplement will be administered in a dose of 4 capsules twice a day for 4 weeks.
One capsule will contain 550 mg of olive oil.
The placebo will be matched to the supplement in appearance.
