Article Review: Omega-3 supplementation on muscular inflammation

Article: Jouris, K. McDaniel, J. & Weiss, E. (2011). The effect of omega-3 fatty acid supplementation on the inflammatory response to eccentric strength exercise. Journal of Sports Science and Medicine, 10 pp. 432-438.


Study Design: 11 People (8 Female, 3 male) underwent a repeated measures intervention trial of 14day low omega 3 intake, 7day high omega 3 intake with testing of eccentric bicep exercise at the end of each trail. Soreness, swelling and size of bicep was measured and reported.


Findings: Whilst there was no significant change in swelling or circumference of the muscle, there was a large increase in soreness in both trails. With omega-3 supplementation however there was a remarked decrease in muscle soreness post supplementation.


Limitations: 11 people is quite a small sample size, so may represent a false-positive.


My Thoughts: The study showed a large decrease in muscle soreness with high dosage of Omega-3 a a 2:1 ratio. This may show benefit to those who are about to complete a large exercise task (i.e. marathon or strength session) to help mitigate a large soreness post event. This also may be beneficial for those beginning exercise (resistance training mainly) to help reduce soreness between sessions and help them continue training with out the large DOMs that comes with new training stimulus. However this was only done with a very small sample size of 11 people and it was a very high dosage, not the most reliable nor practical intervention. I would investigate more before recommending to clients.
