Brief Summary
The purpose of this study was evaluate the comparative effects of FO rich in EPA (FO-EPA) and FO rich in DHA (FO-DHA) on inflammation and neutrophil properties after a prolonged and strenuous exercise. The effect of soybean lecithin on the same parameters and conditions also was evaluated.

Outcome Measures
Primary Outcomes (1)
Neutrophil expression of ICAM-1, L-selectin, FasR and TRAIL
Neutrophil expression was expressed in fluorescence intensity evaluated by flow cytometry at 530/30 nm (FITC) 660/20 nm (APC) or 695/40 nm (PE) wavelengths (BD Accuri cytometer).
Immediately after the first race (Phase II) and immediately after the second race in supplemented athletes (Phase IV).
Secondary Outcomes (1)
Plasma concentrations of IL-1beta, IL-4, IL-6, IL-8, IL-10, and TNF-alpha.
Immediately after the first race (Phase II) and immediately after the second race in supplemented athletes (Phase IV).
Other Outcomes (2)
Blood leukocytes counts
Immediately after the first race (Phase II) and immediately after the second race in supplemented athletes (Phase IV).
Plasma LDH activity
Immediately after the first race (Phase II) and immediately after the second race in supplemented athletes (Phase IV).
Study Arms (2)
dietary supplementation
ACTIVE COMPARATORThe volunteers ingested 3 g daily of Soybean lecithin or fish oil rich in docosa-hexanoic acid (DHA) containing 1.5 g DHA and 0.3 g EPA (DHA:EPA = 5:1) or fish oil rich in eicosapentaenoic acid (EPA) containing 1.6 g EPA and 0.3 g DHA (EPA:DHA = 5.4:1) during 60 days.
Exercise
EXPERIMENTALAll volunteers performed two half-marathons. In the first half-marathon, all participants were not supplemented. In the second half-marathon, participants were supplemented. Blood samples were collected before and after both half-marathon race.
Interventions

All volunteers performed two half-marathons. In the first half-marathon, all participants were not supplemented. In the second half-marathon, all participants were supplemented. Blood samples were collected before and after both half-marathon race.
