“…While this is in contrast to other studies which have considered similar scenarios (Jouris et al, 2011), the lack of impact on perceived muscle soreness reflects work by Lenn et al (2002) and Houghton and Onambele (2012). It is likely that the lack of effect in the current work was due to the nature of the supplementation, in the fact that it was an acute, rather than a chronic supplementation protocol.…”

“…Omega-3 fish oil is a supplement which has increased in popularity as it has potent anti-inflammatory effects and is associated with a lower risk of coronary heart disease (Hu et al, 2002). The two primary constituents of fish oil, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are thought to reduce the production and release of arachidonic acid and pro-inflammatory prostaglandins, among others, with this being particularly true of EPA (Tartibian et al, 2011;Lenn et al, 2002). Accordingly, it has been suggested that fish oil can ameliorate symptoms of EIMD, including soreness and swelling (Jouris et al, 2011).…”

“…Accordingly, it has been suggested that fish oil can ameliorate symptoms of EIMD, including soreness and swelling (Jouris et al, 2011). Typically, prolonged supplementation periods, including 7, 21, 26 and 30 days, have been used to assess the effect of fish oil in moderating EIMD, as it has been demonstrated that chronic supplementation can result in EPA and DHA being incorporated into cellular membranes (Jouris et al, 2011;Houghton and Onambele, 2012;Mickleborough et al, 2015;Lembke et al, 2014;Lenn et al, 2002). Recent research has concluded that EPA and DHA supplementation in a 2:1 ratio may be beneficial to attenuating symptoms of EIMD when consumed chronically (8 weeks; Tsuchiya et al, 2016).…”

Effect of an acute dose of omega-3 fish oil following exercise-induced muscle damageAbstract Purpose: The purpose of this double blind, placebo controlled study was to examine the effect of two fish oil supplements, one high in EPA (750mg EPA, 50mg DHA and one low in EPA (150mg EPA, 100mg DHA), taken acutely as a recovery strategy following EIMD.Methods: Twenty-seven physically active males (26 ± 4 yr, 1.77 ± 0.07 m, 80 ± 10 kg) completed 100 plyometric drop jumps to induce muscle damage. Perceptual (perceived soreness) and functional (isokinetic muscle strength at 60 0 and 180 0 ·s -1 , squat jump performance and countermovement jump performance) indices of EIMD were recorded before, and 1, 24, 48, 72, and 96h after the damaging protocol. Immediately after the damaging protocol, volunteers ingested either a placebo (Con), a low EPA fish oil (Low EPA) or a high EPA fish oil (High EPA) at a dose of 1g per 10kg body mass.Results: A significant group main effect was observed for squat jump, with the High EPA group performing better than Con and Low EPA groups (average performance decrement, 2.1%, 8.3%and 9.8%, respectively), and similar findings were observed for countermovement jump performance, (average performance decrement, 1.7%, 6.8% and 6.8%, respectively, p = 0.07).Significant Time, but no interaction main effects were observed for all functional and perceptual indices measured, although large effects sizes demonstrate a possible ameliorating effect of high dose of EPA fish supplementation (effect sizes ≥ 0.14).

“…Positive effects on DOMS may be augmented by the ability of n-3 acids to increase blood flow, thereby aiding in a more rapid nutrient delivery post-exercise. Some studies have shown a beneficial effect [75] while others have not [41]. Further studies are warranted to assess whether n-3 acids may, in fact, produce analgesic effects.…”

SummaryOmega-3 (n-3) fatty acids, and the long-chain n-3 derivatives eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in particular, have been extensively researched for their nutritive effects. Among their many purported benefits, n-3 acids have been implicated as positive mediators of cardiovascular health and body composition. It has therefore been speculated that supplementation may enhance the beneficial effects of physical activity, potentiating greater reductions in body fat and improvements in exercise performance. This paper has three objectives: first, to assess the theoretical basis for a synergistic ef-fect when n-3 supplementation is combined with exercise; second, to review the literature as to specific findings on the subject and third, to make relevant conclusions and recommendations for future research.

“…While no significant difference was observed between groups for pain level of the lower limbs and knee range of motion before, immediately after, and 24 hr after the exercise, a significant decrease in indirect indices of delayed-onset muscle soreness (DOMS), such as perceived pain, thigh circumference (indicator of muscle swelling/inflammation), and range of motion, and were seen 48 hr after exercise in the omega-3 PUFA group compared with the placebo and control groups. In contrast, Lenn et al (2002) examined the effects of 1.8 g/day of fish oil and isoflavones on DOMS for 30 days before and after 7 days of eccentric exercise and found no significant effects of attenuated perceived pain. It is possible that differences in the eccentric-exercise protocol or the muscle groups that were studied contributed to the differences in findings between the two studies (Lenn et al, 2002;Tartibian et al, 2009).…”

Omega-3 Polyunsaturated Fatty Acids in Physical Performance Optimization

Increased muscle oxidative stress and inflammatory responses among athletes have been reported consistently. In addition, it is well known that exhaustive or unaccustomed exercise can lead to muscle fatigue, delayed-onset muscle soreness, and a decrement in performance. Omega-3 polyunsaturated fatty acids (PUFAs) have been shown to decrease the production of inflammatory eicosanoids, cytokines, and reactive oxygen species; have immunomodulatory effects; and attenuate inflammatory diseases. While a number of studies have assessed the efficacy of omega-3 PUFA supplementation on red blood cell deformability, muscle damage, inflammation, and metabolism during exercise, only a few have evaluated the impact of omega-3 PUFA supplementation on exercise performance. It has been suggested that the ingestion of EPA and DHA of approximately 1-2 g/d, at a ratio of EPA to DHA of 2:1, may be beneficial in counteracting exercise-induced inflammation and for the overall athlete health. However, the human data are inconclusive as to whether omega-3 PUFA supplementation at this dosage is effective in attenuating the inflammatory and immunomodulatory response to exercise and improving exercise performance. Thus, attempts should be made to establish an optimal omega-3 fatty-acid dosage to maximize the risk-to-reward ratio of supplementation. It should be noted that high omega-3 PUFA consumption may lead to immunosuppression and prolong bleeding time. Future studies investigating the efficacy of omega-3 PUFA supplementation in exercise-trained individuals should consider using an exercise protocol of sufficient duration and intensity to produce a more robust oxidative and inflammatory response.
