Introduction : The essential role of Omega-3 in sports physiology  

Omega-3 fatty acids are essential bioactive lipids that the human body cannot synthesize itself. They play a crucial role in modulating inflammatory processes, cardiovascular health, and neuronal function. The long - chain omega-3 fatty acids eicosapentaenoic acid ( EPA ) and docosahexaenoic acid ( DHA ) are particularly relevant for athletes because they can optimize various physiological parameters. Scientific studies demonstrate that a targeted intake of omega-3 not only supports muscle regeneration but also increases performance and reduces the risk of training-related injuries. There is also evidence that a sufficient supply of omega-3 strengthens the immune system and thus reduces athletes ' susceptibility to infection . 

The main sources of omega-3 fatty acids are fatty cold-water fish such as salmon, mackerel, and sardines. Plant-based alternatives such as flaxseed, chia seeds, and walnuts provide alpha-linolenic acid (ALA), which, however, is only converted to EPA and DHA to a limited extent. Targeted supplementation with fish oil or algal oil therefore represents an effective strategy to ensure optimal supply.  

Muscular regeneration and adaptation: influence of omega-3 on recovery processes  

Intense physical activity leads to micro- injuries or micro-traumas in the muscles, which are associated with local inflammatory reactions and oxidative stress. Omega-3 fatty acids, through their inflammation-modulating properties, can inhibit the expression of pro-inflammatory cytokines such as IL-6 and TNF-α, thus shortening recovery time.  

Regular intake of EPA and DHA has been shown to reduce markers of muscle damage and accelerate muscle strength recovery after strenuous exercise. Omega-3 fatty acids can also promote protein synthesis and muscle adaptation, which is particularly important in strength and hypertrophy training . Omega-3 fatty acids also improve mitochondrial biogenesis, making muscular energy production more efficient.  

Performance improvement: More energy and efficiency through optimized metabolism  

Efficient energy metabolism is essential for athletic performance. Omega-3 fatty acids optimize mitochondrial function and increase fat oxidation, enabling prolonged glycogen storage during physical exertion. This represents a significant advantage, especially for endurance athletes .  

Furthermore, a balanced intake of EPA and DHA contributes to improved microcirculation by reducing blood viscosity and stabilizing endothelial function. This results in a more efficient oxygen and nutrient supply to working muscles. Omega-3 also improves ATP synthesis, which plays a key role in muscular performance. Regulation of the autonomic nervous system by omega-3 may also contribute to the optimization of cardiovascular adaptation mechanisms during intense exercise.  

Joint protection: support for pain-free movement  

Exercise-related stress increases the risk of joint inflammation and degenerative changes in cartilage tissue. Omega-3 fatty acids exert anti-inflammatory effects by modulating arachidonic acid metabolism and reducing the synthesis of proinflammatory prostaglandins. Studies show that athletes with a high omega-3 intake have a lower incidence of exercise-related joint pain.  

Additionally, omega-3 promotes the production of synovial fluid, which maintains joint mobility and minimizes wear and tear. Improved collagen synthesis helps stabilize tendon and ligament structures, reducing the risk of musculoskeletal injuries.  

Neurocognitive functions: Improvement of responsiveness and mental resilience  

DHA is an essential component of neuronal membranes and plays a key role in synaptic plasticity and signal transmission in the brain. Optimized omega-3 intake is associated with improved cognitive performance, faster reaction times, and greater mental resilience. This is particularly beneficial for sports that require precise motor control and quick decision-making.  

In addition, studies have shown that omega-3 fatty acids have a positive effect on stress regulation by reducing cortisol secretion This contributes to the reduction of competition stress and mental exhaustion and could lower the risk of sports-related psychological stress disorders .  

Practical application: Optimal dosage for athletes  

The optimal dosage of omega-3 fatty acids for athletes varies depending on individual needs and training intensity. A daily intake of at least 250 mg of EPA and DHA is recommended , although higher amounts may be beneficial during periods of high physical exertion or for specific health needs. Choosing high-quality sources such as wild fish or purified fish oil or algal oil supplements is essential to ensure effective absorption. Omega-3 bioavailability can be improved by combining it with fatty meals. Furthermore, the ratio of omega-6 to omega-3 in the diet should be considered, as excessive omega-6 intake can have a pro-inflammatory effect.
