Delayed-onset muscle soreness (DOMS) is the feeling of discomfort that occurs after being exposed to unaccustomed eccentric resistance training often resulting in diminished athletic performance. Previous research has shown positive effects with omega-3 fatty acid (O3FA) supplementation to ameliorate DOMS. The purpose of this study was to investigate the effects of acute O3FA supplementation on perceived muscle soreness, ratings of exertion, and recovery after a lower body resistance training protocol in college-aged males. A double blind, repeated-measures design was utilized with 10 healthy, college-age males. Participants were placed in the placebo (olive leaf oil) or experimental (O3FA) group, consuming 3,000 mg O3FA for seven days. Exercise protocol consisted of two testing sessions, separated by 24 hours, of the leg press, leg extension, and lying leg curl exercises at 75% 1RM completing three sets until failure for each exercise. Following a seven-day washout period, participants repeated the protocol in the opposite supplement group. A paired sample t-test (α = 0.05) was conducted for 1) total number of repetitions; 2) difference in number of repetitions; 3) perceived ratings of exertion; 4) 24-hour perceived muscle soreness; 5) and recovery status. O3FA supplementation was not effective in improving any variable tested when compared to the placebo: total number of repetitions between conditions (O: 96 ± 17, C: 90 ± 24, p = 0.45); difference in repetitions between tests (O: 6 ± 12, C: 14 ± 11, p = 0.19); RPE (Test 1: Mdn = 5.5, C: Mdn = 6.0, Z = 13.0, p = 0.86; Test 2: Mdn = 6.0, C: Mdn = 7.0, Z = 7, p = 0.88); 24 hour perceived muscle soreness (O: 26.8 ± 21.0, C: 33.7 ± 17.6, p = 0.47); and recovery status (O: Mdn = 6.0, C: Mdn = 4.0, Z = 25.5, p = 0.38). The results suggest that acute O3FA supplementation does not attenuate perceived muscle soreness or improve rating of exertion or recovery 24 hours following induction of DOMS.
