The Normal weight obesity (NWO) syndrome has been characterized on subjects with normal BMI and high body fat mass percentage (BF%>30 on with women) and is a risk factor for cardiometabolic dysregulation and cardiovascular mortality. The aim of this study was to evaluate whether circuit resistance training (CRT) improves body composition, heart size and functions, cardiometabolic parameters, and cardiorespiratory, cardiovascular and skeletal muscle fitness on women with NWO. Subjects/Methods: Data are mean [95%CI]. Twenty-nine white women participated in the study allocated to three groups: ten NWO-CRT (baseline: BMI=22.4 [21.4-23.3] kg/m2; BF%=44.5 [41.0-48.0]%) performed CRT during ten weeks; thirteen untrained NWO-control (baseline: BMI=21.7 [20.8-22.7] kg/m2; BF%=37.8 [34.6-41.1]%) and six non-obese (BMI=19.2 [17.9-20.6] kg/m2; BF%=23.6 [18.3-29.0]%). At baseline (all groups) and after ten weeks (NWO groups) performed: dualenergy- X-ray-absorptiometry, echocardiography, blood tests, arterial pressure, exercise testing, and total-overload-by-training-session (TOL) was calculated. Results: At baseline NWO-control showed almost double of body fat mass (BF) (22.41 [19.5-25.3] kg) than nonobese (11.88 [9.0-14.8] kg) (p=0.0001), and NWO-CRT had more BF than NWO-control (27.28 [23.9-30.6] kg) (p=0.0227). The NWO-CRT after training: reduced more than 8 kg of BF (p=0.000002); the BF% became lower than NWO-control (33.1 [30.1-36.0] < 37.0 [34.3- 39.6]%, p=0.0423) with 30% of NWO-CRT becoming non-obese; reduced 3 kg of trunk fat mass (p=0.000005); showed fasting glucose (72.8 [69.4-76.2] mg/dl) smaller than NWOcontrol (81.7 [78.6-84.8] mg/dl) (p=0.004) and non-obese (92.7 [86.6-98.8] mg/dl) (p=0.000003); increased TOL (5,087.5 [4,142.5-6,032.5] to 6 963.3 [6,226.4-7,700.2] rep.kg, p=0.0004); increased load at VO2peak (122.5 [106.8-138,2] to 137.5 [118.18-156.82] W, p=0.0051); reduced the double product/load at VO2peak ratio (277.4 [222.1-332.8] to 237.7 [194.2-281.2] mmHg.bpm/W, p=0.0015). The CRT increased left ventricular mass/body surface area ratio (84.29 [78.98-89.6] to 90.29 [81.45-99.12] g/m2, p=0.0215). Conclusions: CRT improves the body composition, cardiovascular and skeletal-muscle fitness and reduces fasting glucose without cardiorespiratory changes on normal weight obese women.
Impactos dos programas para a segurança do alimento (BPF e APPCC) adotados por empresas produtoras de alimentos para animais

The need to ensure the quality and safety of food becomes increasingly a concern of the entire food production chain, from primary production to final consumption. Feed industry is an important link in this chain, because the food given to livestock can influence the quality and safety of animal products. To ensure food safety adoption of Good Manufacturing Practices (GMP), which, for the animal feed industry has become mandatory implementation in Brazil, from 2003 is required, and preventive approach programs like Hazard Analysis and Critical Control Points (HACCP), whose implementation is not mandatory. This dissertation analyzes the internal and external impacts of the implementation of GMP / HACCP factories in the feed industry associated to Sindirações as well as the perceived difficulties during deployment. We conducted a survey research (survey), through a questionnaire sent to companies, yielding 60 response units. The data were analyzed in order to characterize companies, test possible correlations between the study variables and evaluate corporate groupings (clusters) with similar characteristics. Cluster analysis showed three groups, distinguished from each other mainly by the size of the unit and certifications standards for food safety. Although the quality of the product is a general requirement of the sector, the understanding that the adoption of programs to ensure the safety of foods is important for product quality and essential to the quality of food of animal origin food supplied to the final consumer does not seem to be unanimous in researching industry. It was observed that the plants that meet the most demanding markets tend to adopt these programs as well as certification. The main internal impacts, reported after the implementation of GMP / HACCP have been improvements in the occurrence of food security issues and improving the level of training of production employees, with respect to external impacts, the most cited were improved image brand and the improvement in customer satisfaction.
