The objective of this study is to evaluate the effect of interdisciplinary therapy in the parameters of the oxidative stress and the anti-inflammatory responses of obese adolescents. We selected 57 participants, who were randomly divided into 2 groups: interdisciplinary therapy group and a control group. After 6 months of intervention, 17 participants of the interdisciplinary therapy group and 8 of the control group returned for re-evaluation. The interdisciplinary therapy group participated in a treatment with 4 weekly sessions of exercise, a weekly group therapy session and a weekly nutritional education session. Blood parameters of oxidative stress and anti-inflammatory response were evaluated. The results demonstrated that there were significant increases in the interdisciplinary therapy group for superoxide dismutase activity (6.56 ± 3.22 to 11.40 ± 7.49) and ferric-reducing antioxidant potential concentration (532.91 ± 106.48 to 573.25 ± 112.57), although adiponectin levels did not reduce (40.9 ± 29.34 to 49.05 ± 41.22). A significant decrease in nitrite levels was also found (14.23 ± 8.48 to 11.45 ± 6.05). In the control group, significant reduction was found in adiponectin (31.56 ± 18.88 to 18.01 ± 11.66). This study suggests that interdisciplinary therapy for 6 months was effective in improving the anti-inflammatory responses and the antioxidant defences in obese adolescents.

The purposes of this study were: 1) investigate whether different markers of infl ammation (CRP and TNF-alpha) are correlated to cardiorespiratory fi tness in adolescents with obesity; 2) examine the association of these variables when adjusted by parameters of body composition. Were selected 57 individuals, 34 girls and 23 boys, with 16.4±1.56 years and body mass index 36.0±4.3 kg/m2. Anthropometric measurements (weight, height and abdominal circunference) and body composition (BMI, visceral fat, body fat) were assessment. Body composition was estimated by analyzer of tetrapolar bioelectrical impedance. Obesity was defi ned as BMI>95th percentile of the curve proposed by the Center for Diseases Control. Plasma TNF-alpha was measured by a quantitative two-site high-sensitivity enzyme immunoassay and CRP was measured by high-sensitivityimmunoturbidimetric assay. Graded maximal exercise testing was performed to obtain the maximum oxygen consumption (VO2max) and velocity associated with the VO2max (vVO2max). Signifi cant correlations of CRP with VO2max and vVO2max were found (r=-0.40 and r=-0,36, respectively). No correlations were observed between TNF-alpha and VO2max e vVO2max. CRP was associated to the VO2max and vVO2max independently of measurements of body composition. The CRP was independently and inversely associated with direct measurement of VO2max and the indirect variable of cardiorespiratory fitness vVO2max, in obese adolescents, even after adjustments in body composition, a potential confounding factor. No association was found between TNF-alpha and the parameters of cardiorespiratory fitness.

A amostra foi composta de 14 indivíduos do sexo masculino e 20 do sexo feminino, com idade (16,8±1,6) e índice de massa corporal (IMC) (35,7±3,9). A ocorrência de EHNA e SM foi de 76,5% (n=26) e 50% (n=17), respectivamente. O sexo masculino apresentou maior ocorrência de EHNA (78,6%, n=11), SM (64,3%, n=09) e associação de EHNA com SM (50%, n=07). Em relação aos FRCs 100% (n=34), 61,8% (n=21) e 52,9% (n=18) dos adolescentes apresentaram valores aumentados da circunferência da cintura (CC), da lowdensity-lipoprotein cholesterol (LDL-C) e pressão arterial sistólica (PAS), respectivamente, e 52,9% (n=18) apresentaram baixos valores de high-density lipoprotein cholesterol (HDL-C). Houve correlações entre SM e triglicerídeos, PAS e diastólica e HDL-C, e entre EHNA, IMC e CC. Conclusão: Observou-se uma alta ocorrência de EHNA, SM e FRCs em adolescentes obesos. Uma forte correlação foi observada entre EHNA e SM, e entre FRCs com EHNA e SM.Descritores: Adolescentes; Obesidade Infantil; Fígado Gorduroso; Síndrome X Metabólica; Doenças Cardiovasculares. (LDL-C) ABSTRACT Objective: To evaluate the association between nonalcoholic hepatic steatosis (NAHS), metabolic syndrome (MS) and cardiovascular risk factors (CRF) in obese adolescents

comparação entre diferentes cargas na avaliação em teste anaeróbio de Wingate adaptado para membros superiores PalavRas chave: teste anaeróbio de Wingate. cicloergômetro de membros superiores. carga. resumo há muita informação acerca do teste de Wingate para membros inferiores, contudo pouco se sabe sobre a padronização deste teste para membros superiores. assim, o objetivo deste estudo foi comparar diferentes cargas do teste de Wingate adaptado para membros superiores. Participaram do estudo 9 homens que foram submetidos a quatro testes de Wingate de 10 segundos em cicloergômetro para membros superiores com diferentes cargas (4, 5, 6 e 7% do peso corporal). não houve diferença na potência média absoluta e relativa entre as
