  • Biochemical Changes and Ponderal Weight After Administration of a Hyperlipidic Diet in Swiss Mice

    Introduction: The type of diet influences the metabolic functions and leads to changes in weight and/or body composition. Researchers have been trying to develop animal models in order to mimic the metabolic states of disorder that occur in humans. Aim: To analyze the metabolic changes after administration of a hyperlipid diet in Swiss mice. Methods: Twenty male Swiss mice weighing 39 – 44g with 120 days old were used. The control group (CG) was maintained on a standard balanced diet (Presence®: 23% protein, 4% fat, 50% carbohydrate and 23% other components), whereas the experimental group (EG) received a special diet with formulation with a high fat content (37.20% encephalon powder, 41.86% crushed feed, 18.60% lard and 2.32% cellulose). The Protocol was approved by the Ethics Committee on Animal Use (CEUA) of the Center for Higher Education and Development (CESED), with Protocol No. 2010/4573. The statistic was performed by Student’s t-test. Results: The initial weight of the animals of the GC and GE groups were 383g and 389g, respectively, and the final weight was 385g and 424g, respectively, with a difference of 39g more for the group that received only the hyperlipidic diet. Cholesterol analysis were 57.4 ± 5.38 for GC and 100.2 ± 10.43 for the GE, where p = 0.0013, whereas for triglycerides values observed were of 50.4 ± 16.62 and 91, 91,6 ± 30.6 respectively. Discussion: The hyperlipid diet significantly increased animal weight, plasma triglyceride concentration, and cholesterol. As demonstrated in other studies this diet was also efficient in increasing body adiposity in this study. Conclusion: The hyperlipidic diet elaborated in this study demonstrates as an excellent model for induction of obesity and dyslipidemia in mice.

  • The Exercise Physical Practice Importance as Diabetes Prevention of Type 2 Mellitus

    Introduction: Type 2 Diabetes Mellitus is a chronic disease related to modern lifestyle and inactivity, accounting for 90-95% of diagnosed cases. The beginning of continuous physical practices characterized as aof form prevention for people susceptible to this type of illness. Objectives: describe how physical activity can prevent the onset of diabetes mellitus type 2. Methodology: It is an integrative review, which used articles were obtained from the data base: MEDLINE. The descriptors being used: Healthy behaviors, Type 2 diabetes, Exercise and Quality of life, using the logical AND operator. Through employee, descriptors were identified 18 publications, of which 12 were excluded for not suit the theme of the study, editorials and reviews. Being admitted the following inclusion criteria: articles published in Portuguese and English, the years 2010 to 2017. The guiding question was: how physical exercise helps in the prevention of type 2 diabetes mellitus? Results and Discussion: The items used were published one in each year, respectively: 2010, 2012, 2013, 2014 and two in 2015, which showed that physical activities with guidance and regulars contributes positively to the reduction of weight and levels of cholesterol, and is associated with significant improvements in blood pressure, the same way that adds sensitivity to insulin and therefore improves the quality of life related to health. The article 2015 reports the existence dandy cost savings with treatment as prevention reduces spending on medication. Conclusion: It is proven that improvements in lifestyle, along with constant practice of physical exercise and low intensity prevent type 2 diabetes mellitus.

  • Evaluation of Respiratory Musculature Work in High Performance Athletes

    Introduction: The high yield sport is an activity where athletes need to improve performance, seeking expected results. Breathing supports, influencing the supply and transport of oxygen; reduction in fatigue, feeling of effort and athlete’s decision. Goals: Increase muscle strength and respiratory capacity, verifying cardiorespiratory repercussions in training. Methodology: The study was conducted at Sport Club do Recife, with 5 male Handball players individuals. Were submitted to respiratory assessment through POWER BREATHE carehealth 2 controlled by the breathlink software, performing 2 sessions 10 minutes long, 2 times a week, for 5 weeks. The charge for first session was 60% of the maximum inspiratory pressure (Pimáx) increased by 5%. Results: There has been an increase in Pimax in 80% of athletes, being 75% raised the average volume of air inspired by incursion. All presented beneficial physiological adaptations with the progression of respiratory load imposed and improves the sense of effort by the Borg scale. Conclusion: It was evidenced that the respiratory muscle training is an important tool in the preparation of high performance athletes, due to provide increased inspiratory muscle force, pulmonar volumes and capacities; and, reducing the sensation of dyspnea and muscle fatigue.
