Abstract
The aim of this study was to investigate the effects of EPA intake over 6 months on EPA concentration, EPA/AA ratio and 5000 m running performance. The results of 58 male collegiate long-distance runners (5000 m: 14 min 30.6 s. ± 30.0 s.) showed that the group that were administered EPA had higher EPA concentration and EPA/AA ratio than the group that were not administered EPA. In addition, EPA concentration, EPA/AA ratio, and 5000m running performance of the administered EPA group improved from pre to post intake and a case analysis of the athletes who were administered EPA demonstrated that EPA concentration, EPA/AA ratio, and 5000 m running performance improved after EPA intake. These results suggest that EPA intake can increase EPA concentration, EPA/AA ratio, and can be predicted to be safe and good for training, and as a result, improve running performance.
