These fats are essential for health, but the body cannot make enough of them, so they must come from foods like oily fish or from supplements. The Index reflects long-term Omega-3 intake and is considered optimal at 8% or higher. Levels below this range have been linked with poorer cardiovascular health (Harris \\& Von Schacky, 2004).\n\n. For athletes, Omega-3 research suggests they can help reduce inflammation, ease muscle soreness, and support immune function. Despite this, many elite athletes appear to have Omega-3 Index values around 4-5%, well below the recommended level of 8%.\n\nTherefore, the aim of this study is to investigate whether increasing the Omega-3 index has any recovery benefits post a bout of downhill running in athletes. Downhill running is commonly used as way to cause exercise-induced muscle damage and study recovery. The Omega-3 index will be increased with a daily fish oil supplement.",[57],"Focus on Omega 3 Index on Recovery","NOT_YET_RECRUITING","2026-02-23",{"date":61,"type":62},"2026-02-27","ACTUAL",{"date":64,"type":51},"2026-02-28",{"date":66,"type":51},"2028-12-30",{"name":5,"class":6}]
