In a randomized controlled trial, Tsuchiya and collaborators assessed the effects of EPA + DHA supplementation on muscle stiffness after eccentric contractions (Tsuchiya et al., 2019). For a period of 8 weeks, a group of 16 participants was evenly divided. One group received 600 mg EPA and 260 mg DHA per day, the other half received a placebo. After the supplementation period, participants performed a one-time exercise, consisting of six sets of 10 eccentric contractions at 100% maximal voluntary contraction with a dumbbell. Parameters of muscle function and stiffness were measured before exercise; immediately after exercise; and 1, 2, and 5 days after exercise. The authors reported that muscle soreness and stiffness were higher in the placebo group. On this basis, they concluded that omega-3 fatty acids EPA and DHA have a positive effect on eccentric contraction-induced muscle soreness and stiffness
