ABSTRACT
Abstract The relation between oxidative stress and inflammation induced by diseases and exercise has increased the interest in the benefits of antioxidant supplements in the improvement of health and physical and mental performance. The aim of this study was to evaluate the effectiveness of açai gel in reducing oxidative stress in individuals engaged in physical activities as well as their acceptance. Sensory evaluation was performed to determine its acceptability and the biochemical parameters related to immune profile and biomarkers of muscle, liver and oxidative stress, with and without the use of gel were evaluated. The appearance, sweetness and overall impression of the açai gel were considered good. It was observed a significant increase in CK enzyme, without the gel as well as the oxidative stress biomarkers, it was observed that the MDA (with and without gel) a significant increase (p < 0.05). Through biochemical evaluation, it is concluded that the gel provided protection for some of parameters studied, since it modulated the immunological parameter reducing the lymphocyte activity and muscular stress. However, more studies must be carried out with a larger number of individuals to confirm the gel functionality.
ABSTRACT
O presente estudo verificou o grau de correlação entre os níveis séricos lipídicos/lipoprotéicos (colesterol total - CT,triglicerídio - TG, lipoproteína de muito baixa densidade ligada ao colesterol - VLDL-c, lipoproteína de baixa densidade ligada ao colesterol - LDL-c e a lipoproteína de alta densidade ligada ao colesterol - HDL-c) e a quantidade de lipídios ingeridos na dieta (lipídios totais - LIPT, lipídios insaturados - LIPIN, lipídios saturados - LIPSA e colesterol - C) de cadetes da Academia Militar das Agulhas Negras (AMAN), que cursam o segundo ano da academia. Participaram do trabalho, cadetes com percentual de gordura superior a 17%, com faixa etária variando entre 20 e 22 anos, em treinamento físico regular. Foram avaliados quanto ao percentual de gordura corporal, consumo de LIPT, LIPIN, LIPSA e C, além dos níveis séricos lipídicos/lipoprotéicos. Utilizou-se o tratamento estatístico descritivo, como também, o teste de correlação de Pearson(r) para determinação das correlações. Houveram correlações significativas entre os níveis obtidos no CT e LIPT (r=0,719, p=0,008<0,01); CT e LIPSA (r=0,697, p=0,012<0,05); e, CT e LIPIN (r=0,596, p=0,041<0,05). Já CT e C (r=0,539, p=0,071>0,05); LDL-c e LIPT (r=0,540, p=0,070>0,05); e, LDLc e LIPSA (r=0,553, p=0,062>0,05), demonstraram correlações médias, porém não significativas. Os dados avaliados indicam principalmente, uma associação entre os níveis de CT sangüíneo e o percentual calórico de LIPT e LIPSA obtidos na dieta, enquanto as outras variáveis, tenderam a se associar, porém não claramente.
The present study verified the degree of correlation between the serics levels of lipidics/lipoproteics (total cholesterol - CT, triglycerides - TG, lipoprotein of very low density to cholesterol - VLDL-c, lipoprotein of low density to cholesterol - LDL-c and the lipoprotein of high density to cholesterol - HDL-c) and the amount of lipids ingested in the diet (Counts lipids LIPT, unsaturateds lipids - LIPIN, saturated lipids - LIPSA and cholesterol - C) of cadets of the Military Academy of Agulhas Negras (AMAN), that attend the second year of the academy. Participated of this study, cadets having body fat percentage higher than 17%, from 20 to 22 years old, in regular physical training. They had been evaluated about the body fat percentage, consume of LIPT, LIPIN, LIPSA and C, beyond the lipidics/lipoproteics serics levels. It was used the descriptive statistical treatment, and also, the Pearson correlation test (r) for determination of the correlations. There was significant correlations between the levels gotten in CT and LIPT (r=0,719, p=0,008<0,01); CT and LIPSA (r=0,697, p=0,012<0,05); and, CT and LIPIN (r=0,596, p=0,041<0,05). However CT and C (r=0,539,p=0,071>0,05); LDL-c and LIPT (r=0,540, p=0,070>0,05); and, LDL-c and LIPSA (r=0,553, p=0,062>0,05), had demonstrated average, but not significant. The evaluated data indicate mainly, an association between the serics levels of CT and the caloric percentile of LIPT and LIPSA gotten in the diet, while the others variables, had tended to associate, however not clearly.
