ObjectiveLong-chain omega-3 polyunsaturated fatty acids (LC ω-3 PUFAs), eicosapentaenoic (EPA) and docosahexaenoic acid (DHA), have received widespread interest from the athletic community for their potential roles in physical performance and recovery. The purpose of this cross-sectional analysis was to evaluate the dietary intake and whole blood ω-3 PUFAs and their relationship with body composition, strength, and power in collegiate athletes.MethodThirty-six athletes completed a dual energy x-ray absorptiometry scan for body composition analysis (n = 35), ω-3 PUFAs food frequency questionnaire (n = 27), provided dried blood spot samples (n = 30) to quantify the Omega-3 Index (O3I) and total ω-3 PUFAs content, handgrip strength (n = 17), and countermovement jump (n = 26) testing.ResultsThe mean daily intake of LC ω-3 PUFAs and O3I was 140 mg and 4.6% ± 0.96, respectively, for all athletes. Dietary LC ω-3 PUFAs were positively correlated with the O3I (r = 0.635, p < .01), whole blood EPA (r = 0.778, p < .01), and DHA (r = 0.515, p < .01). Dietary LC ω-3 PUFA intake, whole blood EPA (%), and the EPA:AA ratio was positively associated with HGS (p < .05). Dietary or blood LC ω-3 PUFAs were not correlated with any other measures.Conclusions:Collegiate athletes consume low amounts of LC ω-3 PUFAs and have sub-optimal O3I status. Sports dietitians should encourage the intake of fatty fish and educate athletes about ω-3 PUFAs potential role on performance- and recovery-based outcomes.
