4th Annual WML Academic Symposium

Purpose: To assess the influence of acute supplementation of docosahexaenoic acid (DHA), Choline and Uridine on anaerobic power output, work capacity and neural cognition. Methods: Eight (8) College-aged males (age: 21.1±1.4 years, height: 176.4±6.2 cm, and weight: 78.9±6.6 kg) completed a baseline assessment and two testing sessions, all two days apart. All sessions consisted of measuring vertical jump, 135 lb bench rep max and completion of the IMPACT neural cognition test. In the two testing sessions, participants received, in random order, either the supplement or a placebo 80 minutes before exercise. Results: No significant difference was shown in either the vertical jump test (p=0.11) or the 135 lb bench press max rep test (p=0.96). There was a significant difference from baseline in two of the IMPACT tests, Visual Motor Speed (VMS) (p=0.08) and Impulse Control (IC) (p=0.05). However, post-hoc analyses indicated no significant difference between the supplement and placebo.

Conclusion: This studies findings suggest that acute supplementation of DHA, Choline and Uridine do not increase anaerobic power output, work capacity and neural cognition. The main reasoning for this is most likely due to the fact that the supplement was ingested acutely. Further studies in which chronic ingestion is the focus are needed to determine rule out this supplements effectiveness with certainty.
