The Relationship

Body composition analysis is relevant to characterize the nutritional requirements and finishing phase of fish. The aim of this study was to investigate the relationship between ichthyometric (weight, total and standard length, density and yields), bromatological (fat, protein, ash and water content) and bioelectrical-impedance-analysis (BIA) (resistance, reactance, phase angle and composition indexes) variables in the hybrid tambatinga (Colossoma macropomum × Piaractus brachypomus). In a non-fertilized vivarium, 520 juveniles were housed and fed commercial rations. Then, 136 days after hatching (DAH), 15 fish with an average weight of 37.69 g and average total length of 12.96 cm were randomly chosen, anesthetized (eugenol) and subjected to the first of fourteen fortnightly assessments (BIA and biometry). After euthanasia, the following parts were weighed: whole carcass with the head, fillet, and skin (WC); fillet with skin (FS); and the remainder of the carcass with the head (CH). Together, FS and CH were ground and homogenized for the bromatological analyses. Estimates of the body composition and yields of tambatinga, with models including ichthyometric and BIA variables, showed correlation coefficients ranging from 0.81 (for the FS yield) to 1,00 (for the total ash). Similarly, models that included only BIA variables had correlation coefficients ranging from 0.81 (FS and CH yields) to 0.98 (for the total ash). Therefore, in tambatinga, the BIA technique allows the estimation of the yield of the fillet with skin and the body composition (water content, fat, ash, and protein). The best models combine ichthyometric and BIA variables.

ABSTRACT Objective To compare body composition of postmenopausal women with and without dynapenia, defined by different cut-off points. Methods Body composition was assessed by electrical bioimpedance and the nutritional status by the body mass index. Dynapenia was diagnosed according to handgrip strength, using the following cut-off points: handgrip strength <16kgf and <20 kgf. Results A total of 171 women (50 to 92 years of age) participated in the investigation. The mean age of non-dynapenic and dynapenic women (handgrip strength <20kgf) was 69.4±8.2 and 74.5±8.2 years, respectively. The mean age of women with dynapenia (handgrip strength <16kgf) was 75.0±10.1 years and non-dynapenic women, 71.1±8.2 years. It was found that dynapenic women, with handgrip strength <20 and <16kgf, had an average of 2.38 and 2.47kg less muscle mass respectively, when compared to non-dynapenic women (p<0.05). However, there was no difference in muscle mass between the different dynapenic groups. Non-dynapenic women (handgrip strength ≥20kgf) had more total (3.55kg) and central fat (1.47kg) (p<0.05). Conclusion Dynapenic women, diagnosed considering both cutoff points, had less total and segmental muscle mass compared to non-dynapenic women. In addition, dynapenic women with handgrip strength <20kgf had lower total and trunk adiposity.

Measurement of body composition is an issue of growing interest that can be used to science research or clinical purposes. For professionals at the health sciences field, it is important to know characteristics of different methods of evaluation and analysis of body composition in order to decide what method should be used in each case, to carry out a better evaluation of the state of health and the risk of a person to becoming ill (by deficit or excess). Then, using these data, it could be performed the corresponding therapeutic strategy. Specifically for patients with eating disorders, a complete evaluation of it is useful, mainly due to body changes, increases or decreases in fat mass and lean mass (for example in anorexia nervosa, bulimia nervosa or binge eating disorder). A similar strategy could be assumed to patients with overweight or obesity.

AbstractThe phase angle is a versatile measurement to assess body composition, frailty and prognosis in patients with chronic diseases. In cirrhosis, patients often present alterations in body composition that are related to adverse outcomes. The phase angle could be useful to evaluate prognosis in these patients, but data are scarce. The aim was to analyse the prognostic value of the phase angle to predict clinically relevant events such as hospitalisation, falls, and mortality in patients with cirrhosis. Outpatients with cirrhosis were consecutively included and the phase angle was determined by electrical bioimpedance. Patients were prospectively followed to determine the incidence of hospitalisations, falls, and mortality. One hundred patients were included. Patients with phase angle ≤ 4.6° (n = 31) showed a higher probability of hospitalisation (35% vs 11%, p = 0.003), falls (41% vs 11%, p = 0.001) and mortality (26% vs 3%, p = 0.001) at 2-year follow-up than patients with PA > 4.6° (n = 69). In the multivariable analysis, the phase angle and MELD-Na were independent predictive factors of hospitalisation and mortality. Phase angle was the only predictive factor for falls. In conclusion, the phase angle showed to be a predictive marker for hospitalisation, falls, and mortality in outpatients with cirrhosis.

Deep Water Running

Abstract Background Interval training in deep water running (DWR-IT) is a training method to improve cardiovascular fitness, functional health, and quality of life and to help control body weight. Its main advantages are the reduction of joint overload and a low risk of musculoskeletal injuries. The aim of the study is to investigate the influence of DWR-IT on functional capacity, body composition, and quality of life of overweight middle-aged adults. Methods This is a randomized controlled, two-arm, open, parallel clinical trial with overweight adults. Volunteers will be allocated to a water group (WG), which will be submitted to the intervention, or a control group, which will not be subjected to any kind of intervention. The evaluation will be composed of anamnesis, electrical bioimpedance, six-minute walk test (6MWT), questionnaire on the Impact of Weight on Quality of Life-lite (IWQOL-LITE), Pittsburgh Sleep Quality Index, Epworth Sleepiness Scale, chair stand test, arm curl test, and food frequency questionnaire. The DWR-IT will last for 12 weeks, systematically increasing the intensity and training volume. Discussion The objective of this clinical trial is to evaluate the effect of DWR-IT on overweight adults. The study is guided through practice based on scientific evidence for the use of training and aquatic rehabilitation. It is expected that after 12 weeks of aquatic intervention there will be a decrease in body fat by about 10%, evaluated by electrical bioimpedance, an increase of about 25% of cardiorespiratory endurance, evaluated by 6MWT, and an improvement of about 25% of physical function domains, self-esteem, distress in public places, and work, analyzed by IWQOL-LITE in the WG. Trial registration The study protocol was published in the Brazilian Registry of Clinical Trials (ReBEC) on June 16, 2016. Registration number: RBR-6dmh7d.

Abstract Activities around applications of Electrical Bioimpedance Spectroscopy (EBIS) have proliferated in the past decade significantly. Most of these activities have been focused in the analysis of the EBIS measurements, which eventually might enable novel applications. In Body Composition Assessment (BCA), the most common analysis approach currently used in EBIS is based on the Cole function, which most often requires curve fitting. One of the most implemented approaches for obtaining the Cole parameters is performed in the impedance plane through the geometrical properties that the Cole function exhibit in such domain as depressed semi-circle. To fit the measured impedance data to a semi-circle in the impedance plane, obtaining the Cole parameters in an indirect and sequential manner has several drawbacks. Applying a Non-Linear Least Square (NLLS) iterative fitting on the spectroscopy measurement, obtains the Cole parameters considering the frequency information contained in the measurement. In this work, from experimental total right side EBIS measurements, the BCA parameters have been obtained to assess the amount and distribution of whole body fluids. The values for the BCA parameters have been obtained using values for the Cole parameters estimated with both approaches: circular fitting on the impedance plane and NLLS impedance-only fitting. The comparison of the values obtained for the BCA parameters with both methods confirms that the NLLS impedance-only is an effective alternative as Cole parameter estimation method in BCA from EBIS measurements. Using the modulus of the Cole function as the model for the fitting would eliminate the need for performing phase detection in the acquisition process, simplifying the hardware specifications of the measurement instrumentation when implementing a bioimpedance spectrometer.
