Long-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.Thirty-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.The 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 ( = 0.635, < .01), whole blood EPA ( = 0.778, < .01), and DHA ( = 0.515, < .01). Dietary LC ω-3 PUFA intake, whole blood EPA (%), and the EPA:AA ratio was positively associated with HGS ( < .05). Dietary or blood LC ω-3 PUFAs were not correlated with any other measures.: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.
长链ω-3多不饱和脂肪酸（LC ω-3 PUFAs），即二十碳五烯酸（EPA）和二十二碳六烯酸（DHA），因其在体能表现和恢复方面的潜在作用而受到体育界的广泛关注。本横断面分析的目的是评估大学生运动员的膳食摄入量、全血ω-3 PUFAs及其与身体成分、力量和功率的关系。36名运动员完成了用于身体成分分析的双能X线吸收测定扫描（n = 35）、ω-3 PUFAs食物频率问卷（n = 27），提供干血斑样本（n = 30）以量化ω-3指数（O3I）和总ω-3 PUFAs含量、握力测试（n = 17）和纵跳测试（n = 26）。所有运动员的LC ω-3 PUFAs平均每日摄入量和O3I分别为140毫克和4.6%±0.96。膳食LC ω-3 PUFAs与O3I（r = 0.635，P <.01）、全血EPA（r = 0.778，P <.01）和DHA（r = 0.515，P <.01）呈正相关。膳食LC ω-3 PUFA摄入量、全血EPA（%）和EPA:AA比值与握力呈正相关（P <.05）。膳食或血液中的LC ω-3 PUFAs与其他任何指标均无相关性。大学生运动员LC ω-3 PUFAs摄入量低，O3I状态不理想。运动营养师应鼓励运动员摄入富含脂肪的鱼类，并向运动员宣传ω-3 PUFAs在基于表现和恢复的结果方面的潜在作用。
