Abstract
Introduction: Determination of total antioxidant capacity of plasma is taken as a diagnosis tool and treatment of various diseases, such as cardiovascular disease and diabetes. The antioxidant molecules of the plasma are provided from two intrinsic sources (such as uric acid, albumin and thiols) and exogenous (e.g., vitamins E, C and omega 3), and TAC shows the total activity of each both antioxidants groups existing in the plasma and body fluids. Studies have shown there is a relationship between oxidative stress and synaptic plasticity, also omega-3 fatty acids consuming by reducing oxidative stress, maintain or enhance brain function. This study examined the effect of omega-3 consuming on plasma brain-derived neurotrophic factor (BDNF), malondialdehyde (MDA) and total antioxidant capacity (TAC) after a session of intensive interval exercise, in young active men.
Methodology: In this study, 13 young active men randomly were divided into two groups: omega-3 (n = 7) and placebo (n = 6). The omega-3 group, for 4 weeks, daily 1,000 mg of omega-3 were consumed orally in capsule form. The subjects before and after four weeks of omega-3 consumption, anaerobic RAST test was performed. The Running Based Anaerobic Sprint Test (RAST) involves six sprints over 35 meters with a 10 second recovery between each sprint, and provides measurements of peak power, average power and minimum power along with a fatigue index. This test was repeated four times by each subject, and the subjects two minutes’ recovery between each the two repetitions. Blood samples were collected before and after the test run.
Results: The obtained results showed that taking omega-3 supplements for four weeks, had no significant effect on the plasma levels of BDNF (P=0.4), MDA (P=0.62) and TAC (P=0.72).
Discussion: Apparently, getting regular exercise has more effective than omega-3 supplementation at a dose of 1000 mg per day on BDNF and the oxidant / antioxidant after a session of intensive interval exercise.
