“…The balance between the actions of different cytokines, pro and anti-inflammatory contributes to the complete repair of damaged tissues. In the cascade of cytokines after a stress (e.g., exercise or infection), the initial cytokines appear in the following order TNFa IL1, IL6 receptors of IL1ra cytokines (inhibitor of IL1) and sTNF-R (order TNFa inhibitor), wherein the presence of infection or acute stress many of these cytokines and their receptors are multiplied, and when the effect of stress or infection end generally there is decrease in plasma levels of these cytokines [4]. The major pro-inflammatory cytokines, which are "alarm cytokines", include interleukin (IL-1β) and tumor necrosis factor (TNF).…”

“…Generally, after acute exercise, there is no increase in pro-inflammatory cytokines (IL-1 and TNFa). This can partly be explained by increased IL-6 induces the synthesis of which receptor antagonistic of IL-1 and TNFa (IL1ra and sTNF-R, respectively) and also other antiinflammatory cytokines [4].…”

“…This significant increase has a biological explanation, since through it can induce the synthesis of anti-inflammatory factors, such as sTNF-R, IL1-ra and IL10, possible damage shields caused by excessive pro-inflammatory cytokines in blood circulation. Chronically, both the exercise of strength and aerobic seem to decrease your basal plasma levels [4]. By contrast, regular exercise and physical activity are protective against all-cause mortality through suppressing pro-inflammatory cytokine production, enhancing anti-inflammatory mediators and antioxidant development, and promoting fibrinolytic activity.…”

The human body when subjected to heavy loads of physical training suffers numerous modifications to adapt to stress in which the body is subjected. Various systems are affected directly and indirectly, we can mention the cardio respiratory system as the one that suffers most modifications when we are facing an intense physical load. Another system to modify and in which we will explain in this paper is the endocrine system, specifically the thyroid gland who suffers some changes. This paper aims to demonstrate and exemplify the changes in the thyroid gland during physical activity, such as the release of pro-and anti-inflammatory cytokines, and the alteration occurred in the release of thyroid hormones. All these changes suffer direct influence on the athlete's performance being a limiting factor for a good performance. Through this paper we exemplify the changes that occurred in the thyroid gland during exercise in order to seek an intervention for these transformations, aiming ultimately a good performance of the athlete.

RESuMoIntrodução: A população brasileira tem seguido a tendência dos países desenvolvidos, cuja característica é o aumento do consumo de gorduras e sedentarismo. Objetivo: Investigar os efeitos da dieta hiperlipídica e do treinamento sobre o peso corporal, o consumo alimentar, a massa corporal magra, os lipídios plasmáticos, o peso do fígado e a aterosclerose em camundongos com deficiência de apolipoproteína E (apoE-/-). Métodos: vinte e seis camundongos foram divididos em grupos/dieta: NS (normolipídica e sedentário), HS (hiperlipídica e sedentário), NT (normolipídica e treinamento) e HT (hiperlipídica e treinamento). Aferiu-se peso corporal (PC), consumo alimentar (CA) e peso relativo do fígado (PRF). Calculou-se a água da carcaça (A%) pela diferença do peso pré e pós-secagem, gordura (G%) por Soxhlet e proteína (P%) por Kjeldahl. Determinaram-se colesterol total (CT), triglicerídeos (TG) e HDL por método enzimático-colorimétrico e LDL e VLDL pela formula de Friedewald. Analisou-se a aterosclerose por fotomicrografia. Utilizou-se ANOVA e o método de Duncan, com P < 0,05. Resultados: No PC inicial e final, não houve diferença de G% e P% entre os grupos (P > 0,05). A dieta hiperlipídica aumentou o CA (365,3 ± 5,09 vs. 340,16 ± 6,32) e LDL (452,20 ± 114,63 vs. 329,60 ± 77,54) HDL (14,83 ± 3,95 vs. 37,60 ± 13,12), VLDL (4,55 ± 2,47 vs. 13,20 ± 4,37) e aterosclerose (0,35 ± 0,13 vs. 0,56 ± 0,12) nos hiperlipídicos (P < 0,05). Conclusão: A dieta hiperlipídica pode desencadear distúrbios no metabolismo lipídico e, com isso, desencadear doenças cardiovasculares; porém, associada ao treinamento, pode diminuir a aterosclerose.Palavras-chave: metabolismo, estilo de vida sedentário, composição corporal. Duncan' s method, P<0.05. Results: In the initial and final BW, there was no difference in F% and P% between groups (P>0.05). The high fat diet increased the FI (365,3±5,09 vs. 340,16±6,32) and LDL (452,20±114,63 vs. 329,60±77,54) in the sedentary animals and TC (858,75±140,84 vs. 320,87±157,81) and LDL (839,36±139,94 vs. 282,66±166,92) in trained ones (P<0.05). On the other hand, training increased the CA (350,4±7,81 vs. 340,16±6,32) and A% (64,23±2,46 vs. 62,62±1,47) in normolipidic mice and decreased FI (336,68±6,23 vs 365,3 ± 5,09), TG (22,75±12,36 vs. 66,00±21,88), HDL (14,83±3,95 vs. 37,60±13,12), VLDL (4,55±2,47 vs. 13,20±4,37) and atherosclerosis (0,35±0,13 vs. 0,56±0,12) ABStRAct Introduction: The Brazilian population has followed the trend of developed countries, whose characteristic is the increased consumption of fats and sedentary lifestyle. Objective: To investigate the effects of high fat diet and training on body weight, food intake, lean body mass, plasma lipids, liver weight and atherosclerosis in mice with apolipoprotein E (apoE-/-) deficiency. Methods: 26 rats were divided into groups/diet: NS (normolipidic and sedentary), HS (high fat and sedentary), NT (normolipidic and training) and HT (high fat and training).

Background/objectives Myocardial infarction (MI) frequently leads to cardiac remodeling and failure with impaired life quality, playing an important role in cardiovascular deaths. Although physical exercise is a well-recognized effective non-pharmacological therapy for cardiovascular diseases, the effects of strength training (ST) on the structural and functional aspects of cardiac remodeling need to be further documented. In this study, we aimed to investigate the role of a linear block ST protocol in the rat model of MI. Methods and results After 6 weeks of MI induction or sham surgery, male adult rats performed ST for the following 12 weeks. The ladder-based ST program was organized in three mesocycles of 4 weeks, with one load increment for each block according to the maximal carrying load test. After 12 weeks, the infarcted-trained rats exhibited an increase in performance, associated with reduced cardiac hypertrophy and pulmonary congestion compared with the untrained group. Despite not changing MI size, the ST program partially prevented cardiac dilatation and ventricular dysfunction assessed by echocardiography and hemodynamics, and interstitial fibrosis evaluated by histology. In addition, isolated cardiac muscles from infarcted-trained rats had improved contractility parameters in a steady state, and in response to calcium or stimuli pauses. Conclusions The ST in infarcted rats increased the capacity to carry mass, associated with attenuation of cardiac remodeling and pulmonary congestion with improving cardiac function that could be attributed, at least in part, to the improvement of myocardial contractility.
