Abstract

Fatty acids are important components of human cells. They play a key role in structural, energetic functions as well as signal transduction, among others. Long chain polyunsaturated fatty acids (PUFA) from n-3 and n-6 family are essential to human body and their deficiency causes functional deficit for body development. Therefore, they must be provided in the diet. N-3 polyunsaturated fatty acid’s metabolites have been related to the control of inflammatory disorders and immune system modulation response. Physical activity is a stimulus which also modifies immune system response. In this study, we investigated the effect of fish oil supplementation, rich in n-3 PUFA, to amateur soccer players for 60 days. Serum biochemical parameters and immune system function were determined. Volunteers were divided in two experimental groups: not supplemented (n=9); and supplemented with n-3 (2g/day) for 60 days (n=19). After 60 days, according to serum biochemical parameters, only total cholesterol concentration presented a significant decrease (157,8±7,2 vs. 142,4±8,0 mg/dL, p<0,05). Levels of resting blood glucose, lactate, triacylglycerols and HDL-cholesterol were similar to control, p>0.05. Supplementation did not alter the proliferation capacity of mononuclear cells. Among the analyzed parameters of blood polymorphonuclear cells (PMNS), only cationic vesicles content was significantly altered. This content suffered an increase of 20% when compared to pre supplementation period. Taking in account the time and fish oil dose used here, there were not relevant modifications in the investigated parameters. However, reduction in the total cholesterol concentration and the increase of cationic vesicles content in PMNS can represent potential benefits for people’s health.
