Flavonoids, Antioxidants, and Omega-3 Fatty Acids May Reduce Post-Exercise Oxidative Stress


I love it when I am right! Here is anthor article that supports the ideas I have been using with my athletes for over 15 years. That you can enhance recovery with the use of an antioxidant and anti-inflammatory approach to supplements instead of performance enhancement directly. My athelets know that I am always looking to find new ways to enhance recovery from each workout and its nice when we get another study confirming my approach. Take a look!


Flavonoids, Antioxidants, and Omega-3 Fatty Acids May Reduce Post-Exercise Oxidative Stress

Keywords:OXIDATIVE STRESS, INFLAMMATION - Flavonoids, Antioxidants, Omega-3 Fatty Acids
Reference:"Effect of Mixed Flavonoids, n-3 Fatty Acids, and Vitamin C on Oxidative Stress and Antioxidant Capacity Before and After Intense Cycling," McAnulty SR, Nieman DC, et al, Int J Sport Nutr Exerc Metab, 2011 Aug; 21(4): 328-37. (Address: Dept. of Health, Leisure, and Exercise Science, Appalachian State University, Boone, NC, USA).
Summary:In a randomized study involving 39 athletes, supplementation with flavonoids, antioxidants and omega-3 fatty acids taken for 2 weeks prior to and 3 days during cycling at 57% Wmax for 3 hours, was found to be associated with reductions in the immediate post-exercise increase in F2-isoprostane. Subjects received supplementation with one of the following interventions: 1,000 mg quercetin + 1,000 mg vitamin C; 1,000 mg quercetin + 1,000 mg vitamin C + 400 mg isoquercetin, 30 mg epigallocatechin gallate, and 400 mg omega-3 fatty acids; or, placebo, daily for 2 weeks before and during 3 days of cycling. Subjects in both treatment groups were found to be protected against the significant increase in F2-isoprostanes post-exercise, as found in the placebo group. This effect was found to be independent of changes in plasma antioxidant capacity. These results suggest that supplementation with flavonoids, antioxidants and omega-3 fatty acids may benefit athletes.
