![]() The body can produce choline in limited amounts by using one-carbon groups from the folate metabolism, but most of it has to be supplied by the diet. Given that 90% of the US population is known to consume too little choline, and that European populations also do not reach the recommended daily intake levels of 400 mg, this indicates that athletes might also be at risk of choline deficiency. However, no interventional data exist that establish choline and omega-3 polyunsaturated fatty acid (n-3 PUFA) intake as a supplementation strategy to optimize PT training sessions and recovery, and these important nutrients seem so far to go unnoticed in this sporting discipline. ![]() There are some studies available that evaluated the benefits of nutritional interventions in PT athletes. Since risks for prolonged responses of oxidative stress and inflammation as well as injury and overreaching have been highlighted, dietary interventions may be required to improve athletic performance and speed up recovery. Because this functional movement training method is metabolically very demanding, its beneficial effect on health and on improving athletic performance has been contradictorily assessed. Whereas power lifting focuses on bench press, squat and deadlift, the PT schedule is characterized by functional movements performed at high intensity, combining intervals of strength and endurance that can vary between weightlifting, running, cycling, squatting, pulling, pushing, etc. These activities are known as power training (PT) sports, or high-intensity interval training activities (HIIT), but sometimes popularly referred to as CrossFit, which is a registered trademark (CrossFit TM). The high-intensity modality of exercise performed during short periods of time has gained popularity in the last decades due to factors related to health, fashion and a sense of well-being. In conclusion, krill oil can be used as a nutritional strategy for increasing the HS-Omega-3 Index, recover choline concentrations and address oxidative stress after intense power trainings. ![]() The krill oil group showed significantly higher recovery of choline concentrations relative to the placebo group from the end of the first to the beginning of the second exercise test ( p = 0.04) and an 8% decrease in total antioxidant capacity post-exercise versus 21% in the placebo group ( p = 0.35). ![]() ![]() After 12 weeks, only the krill oil group showed a significant HS-Omega-3 Index increase from 4.82 to 6.77% and a reduction in the ARA/EPA ratio (from 50.72 to 13.61%) ( p < 0.001). Thirty-five healthy power training athletes received either 2.5 g/day of Neptune krill oil TM (550 mg EPA/DHA and 150 mg choline) or olive oil (placebo) in a randomized double-blind design. The purpose of this study was therefore to characterize n-3 PUFA and choline profiles after a one-hour period of high-intensity physical workout after 12 weeks of supplementation. There is evidence that both omega-3 polyunsaturated fatty acids (n-3 PUFAs) and choline can influence sports performance, but information establishing their combined effects when given in the form of krill oil during power training protocols is missing. ![]()
