Objective: To evaluate the hydration of obese and non-obese adolescents by vectorial bioimpedance analysis, in addition to verifying the associations between obesity and bioelectrical impedance vectorial analysis (BIVA) parameters. Methods: A cross-sectional study with adolescents between 14 and 18 years old (n=489, 300 boys and 189 girls). Electric bioimpedance (BIA; Quantum_II, RJL system, Rome, Italy) provided resistance and reactance parameters to calculate phase angle (PA), fat-free mass (FFM) and body fat (%BF). The confidence ellipses were compared, and the construction of the tolerance ellipses allowed individual and qualitative evaluation of the vectors and classification in dehydrated, normohydrated and hyperhydrated. Results: 78 obese and 411 eutrophic adolescents participated. Resistance (p<0.001) and reactance (p<0.001) and their normalization by stature (p<0.001) were reduced in the obese, whereas the PA was higher (p=0.003). %BF was 11.3% higher in obese adolescents. The main vector of the obese, both male (D=1.38; p<0.001) and female (D=1.49; p<0.001), indicated greater hydration. The ellipse of tolerance of the total sample showed that 25 (32.1%) were hyperhydrated and 02 (2.6%) vectors positioned in the sense of dehydration. A total of 17 (53.2%) girls and 16 (34.8%) boys were hyperhydrated. Logistic regression showed an inverse relation of BMI with resistance (p<0.001), reactance (p<0.001) and both normalized by stature. Adolescents with increased PA (p<0.001) were twice as likely to present obesity. Conclusions: Obese adolescents were hyperhydrated and there was an inverse relationship of BMI with resistance and direct with PA.

Este estudo teve como objetivo verificar os efeitos da atividade física em caráter de lazer sobre os sintomas de ansiedade e da aptidão física de dependentes químicos e, analisou também algumas valências físicas como promoção de saúde. Por meio de um estudo de campo de carater experimental sem grupo de controle no Centro de Reabilitação e Amparo Bom Jardim – Distrito de Interlândia – Anápolis – Goiás. Participaram do estudo 8 internos adultos, homens, em tratamento voluntário na unidade. Foram realizadas 12 intervenções. Após uma abordagem inicial foi aplicado o questionário de ansiedade e depressão de BECK e os testes de aptidão física antes e depois das intervenções. Após a intervenção, os participantes realizaram maior número de flexões de membro superior (p=0,03) e percorreu maior distância (200m) no teste de aptidão cardiorrespiratória (p=0,002). Foi constado através do inventario de depressão de BECK que 4 internos se encontravam em estado de depressão mínima e 4 apresentavam score moderado de depressão. Com a intervenção foi reduzido o escore de 9 (5) para 3 (3) (p<0,001).

Objective: To associate and compare the level of physical activity with cardiovascular health (CVH), quality of life, cardiorespiratory fitness, anthropometric variables and workload of active and sedentary women working in a university environment. Methods: Cross-sectional study, carried out with employees of a higher education institution. The sample was for convenience and 51 healthy adult women participated. Seven metrics were evaluated for CVH, using the international physical activity questionnaire and the Mediterranean diet questionnaire. Quality of life was assessed using the Short Form-36 instrument and cardiorespiratory fitness using the shuttle run test. The Student-t test and Mann-Whitney U test were used to analyze the data, and a multiple linear regression was performed with data adjusted for age and the climacteric period. Results: Active women had lower values for waist-hip ratio (WHR) (p=0.001) and diastolic blood pressure (DBP) (p<0.001), and higher results for maximal oxygen consumption (VO2max) (p<0.001), CVH score (p<0.001), functional capacity (p=0.004), and general health (p=0.009). There was a direct relationship with the CVH score (p= 0.018) and VO2max (p= 0.012), and an inverse relationship for workload (p=0.013). Conclusion: The level of physical activity contributes to lower values of risk factors for cardiovascular diseases (WHR and DBP) and higher values of VO2max, SCV scores and quality of life in active women.
