[Profile of body composition in women with class III obesity by multipolar bioimpedance method]. / Perfil da composição corporal de mulheres com obesidade grau III pelo método de bioimpedância multipolar.

OBJECTIVE: To analyze a body composition profile in women with class III obesity using the multipolar bioimpedance method. METHODS: Thirteen sedentary women aged between 20 and 40 years were evaluated. RESULTS: The results show that the patients had a fat percentage of 51.9±1.50 % and lean mass of 48.1±1.50 %. Regarding fat mass and lean mass per body region, figures of 26.3±3.62kg and 26.2±2.91kg in the upper body, 9.1±0.06kg and 8.4±0.14kg in the lower limbs, and 3.3±0.02kg and 7.6±0.01kg in the upper limbs were obtained. Patients had a good symmetry between the left and right sides in both upper and lower limbs, besides of a muscular mass of 32.1±5.08kg, with a muscular mass index of 12.7±1.05kg/m2. CONCLUSION: Higher fat accumulation was observed in the upper body region, followed by lower and upper limbs. Total muscular mass was apparently preserved, although sarcopenic obesity was not verified. Since this is a group of people that is still understudied, there is a need for further research on genetic and physical profile and caloric expenditure during exercise and rest.

[Effects of acute exercise with upper body cycle ergometer in individuals with morbid obesity]. / Efeitos do exercício físico agudo em ciclo ergômetro de membros superiores em indivíduos com obesidade mórbida.

Objective The purpose of this study is to research effects of acute exercise with cycle ergometers adapted for the upper limbs on physiological markers in the morbidly obese. Methods Ten morbidly obese patients participated in the study. They were submitted to thirty minutes of continuous activity on a cycle ergometer adapted to the upper limbs. The following physiological markers were evaluated: systemic arterial pressure, heart rate, the double product, and oxygen saturation. For the statistical analysis, descriptive analysis was used. Results Patients showed a Body Mass Index (BMI) value of 52.1 ± 8.3. Most of the subjects showed a slight reduction in systolic blood pressure (SBP) and diastolic blood pressure (DBP) after physical activity, with SBP before and after physical activity of 135.5±11.4 and 133.5±15.3 mmHg, respectively, and, for DBP, 83±7.5 and 77±7.1 respectively. The average heart rate was 68±10.4 bpm before, 100.6±16.5 bpm during and 80.7±14.5 bpm 1 minute after. The double product (DP) had a mean increase of 29.6±17.1 % in men and 10.4±8.9 % in women when compared with the initial phase. The oxygen saturation showed no mean difference before, during or after activity. Conclusion It can be concluded that acute physical exercise with an upper limbs cycle ergometer in morbidly obese patients does not represent an elevated risk to these patients, being in fact a good intervention to promote health.
