The Impact

The metabolic syndrome comprises an array of cardiovascular disease (CVD) risk factors such as abdominal obesity, dyslipidemia, hypertension, and glucose intolerance. Insulin resistance and/or increased abdominal (visceral) obesity have been suggested as potential etiological factors. More recently, increasing evidence has associated insulin resistance and subclinical inflammation involving cytokines derived from adipose tissue, or adipocytokines. Despite the fact that precise mechanisms have yet to be established, there is a significant role for both diet and physical activity to improve the many factors associated with the metabolic syndrome, including modulation of various adipocytokines. Although both diet and physical activity have been studied for their ability to modify cytokines in more traditional inflammatory conditions, such as rheumatoid arthritis, they have been less studied in relation to inflammation as an underlying cause of the metabolic syndrome and/or CVD. A more thorough understanding of the clustering of metabolic abnormalities and their underlying etiology will help to define diet and physical activity guidelines for preventing and treating the metabolic syndrome, an important aspect of CVD prevention. This paper will address potential underlying causes of the metabolic syndrome, with a focus on the putative mechanistic role of adipocytokines, and will discuss the impact of diet and physical activity on the metabolic syndrome.

Inflammatory Pattern

SummaryExtensive research of the past decades altered our traditional concept about the genesis of atherosclerosis fundamentally. Today, the crucial role of inflammation in the formation and progression of atherosclerotic plaques is indisputable. Patients at high risk for developing cardiovascular disease, owing to poor diet, obesity and low physical activity have been shown to exhibit a particular inflammatory pattern.Therefore, the present review highlights the crosslink between the metabolic syndrome (MetS), adipose tissue, adipokines and selected inflammatory cytokines in the context of atherothrombosis and cardiovascular disease.

Exercise Induced

The lack of adequate physical activity and obesity created a worldwide pandemic. Obesity is characterized by the deposition of adipose tissue in various parts of the body; it is now evident that adipose tissue also acts as an endocrine organ capable of secreting many cytokines that are though to be involved in the pathophysiology of obesity, insulin resistance, and metabolic syndrome. Adipokines, or adipose tissue-derived proteins, play a pivotal role in this scenario. Increased secretion of proinflammatory adipokines leads to a chronic inflammatory state that is accompanied by insulin resistance and glucose intolerance. Lifestyle change in terms of increased physical activity and exercise is the best nonpharmacological treatment for obesity since these can reduce insulin resistance, counteract the inflammatory state, and improve the lipid profile. There is growing evidence that exercise exerts its beneficial effects partly through alterations in the adipokine profile; that is, exercise increases secretion of anti-inflammatory adipokines and reduces proinflammatory cytokines. In this paper we briefly describe the pathophysiologic role of four important adipokines (adiponectin, leptin, TNF-α, and IL-6) in the metabolic syndrome and review some of the clinical trials that monitored these adipokines as a clinical outcome before and after exercise.

The Impact

Polycystic ovary syndrome is a highly frequent reproductive-endocrine disorder affecting up to 8–10% of women worldwide at reproductive age. Although its etiology is not fully understood, evidence suggests that insulin resistance, with or without compensatory hyperinsulinemia, and hyperandrogenism are very common features of the polycystic ovary syndrome phenotype. Dysfunctional white adipose tissue has been identified as a major contributing factor for insulin resistance in polycystic ovary syndrome. Environmental (e.g., chronodisruption) and genetic/epigenetic factors may also play relevant roles in syndrome development. Overweight and/or obesity are very common in women with polycystic ovary syndrome, thus suggesting that some polycystic ovary syndrome and metabolic syndrome female phenotypes share common characteristics. Sleep disturbances have been reported to double in women with PCOS and obstructive sleep apnea is a common feature in polycystic ovary syndrome patients. Maturation of the luteinizing hormone-releasing hormone secretion pattern in girls in puberty is closely related to changes in the sleep-wake cycle and could have relevance in the pathogenesis of polycystic ovary syndrome. This review article focuses on two main issues in the polycystic ovary syndrome-metabolic syndrome phenotype development: (a) the impact of androgen excess on white adipose tissue function and (b) the possible efficacy of adjuvant melatonin therapy to improve the chronobiologic profile in polycystic ovary syndrome-metabolic syndrome individuals. Genetic variants in melatonin receptor have been linked to increased risk of developing polycystic ovary syndrome, to impairments in insulin secretion, and to increased fasting glucose levels. Melatonin therapy may protect against several metabolic syndrome comorbidities in polycystic ovary syndrome and could be applied from the initial phases of patients’ treatment.

The Impact

Metabolic syndrome is a cluster of cardiometabolic risk factors. They include obesity, dyslipidemia, hypertension, and insulin resistance. Central obesity and resistance to insulin, in particular, are recognized as causative factors, which form the development of metabolic syndrome. Metabolic syndrome is a progressive and genetically determined condition. The result of its progression is that carbohydrate, lipid and purine metabolism break down. The intestinal microbiome has a significant role in the pathogenesis of metabolic syndrome. One of the methods of influencing the micribiotic composition is the physical activity. The human intestinal microbiome is a complex ecosystem consisting not only of microorganisms, but also including bacteria, archaea, fungi and viruses. Biodiversity and the overall composition of the microbiota play a crucial role in maintaining normal homeostasis in the human body. With the recent advent of the possibility of studying the intestinal microbiome, the impact on its taxonomic composition and metabolism through exercise is the subject of scientific interest. Recent studies showed that the intestinal microbiota was directly involved in the formation of the metabolic syndrome. The function of the microbiome is just as important as the function of the "metabolic organs" that affect energy homeostasis and control body weight. In addition, changes in the intestinal microbiotic composition lead to increased intestinal permeability, endotoxemia, which plays a role in the development of chronic inflammation in the host, contributing to the development of metabolic syndrome and related chronic metabolic diseases. Intestinal microbiota in its own right is injected into the development of systemic inflammation in obesity, such a rank, inappropriate insertions in development or regression of insulin resistance, and hyperglycemia in metabolic syndrome. Physical activity can affect not only the composition of the microbial composition, but also the metabolic activity of the intestinal microbiome. The health-improving effect of physical exercises is connected with their ability to change the composition of an intestinal microbiota. Studies involving professional athletes and a specially selected control group indicated that athletes had a lower pro-inflammatory status and a high degree of bacterial diversity. Due to this, there is a positive dynamics of improving carbohydrate metabolism and the impact on the course of pathological processes associated with the metabolic syndrome, through the introduction of regular physical activity. Conclusion. The literature review presents data on the metabolic syndrome, its pathogenesis and components of the spectrum of development of metabolic disorders. We also analyzed material on influence of gut microbiota on development of metabolic disturbances and inreraction of structure of a microbiotic composition with physical exercises

The Impact

Both observational and interventional studies suggest an important role for physical activity and higher fitness in mitigating the metabolic syndrome. Each component of the metabolic syndrome is, to a certain extent, favorably influenced by interventions that include physical activity. Given that the prevalence of the metabolic syndrome and its individual components (particularly obesity and insulin resistance) has increased significantly in recent decades, guidelines from various professional organizations have called for greater efforts to reduce the incidence of this condition and its components. While physical activity interventions that lead to improved fitness cannot be expected to normalize insulin resistance, lipid disorders, or obesity, the combined effect of increasing activity on these risk markers, an improvement in fitness, or both, has been shown to have a major impact on health outcomes related to the metabolic syndrome. Exercise therapy is a cost-effective intervention to both prevent and mitigate the impact of the metabolic syndrome, but it remains underutilized. In the current article, an overview of the effects of physical activity and higher fitness on the metabolic syndrome is provided, along with a discussion of the mechanisms underlying the benefits of being more fit or more physically active in the prevention and treatment of the metabolic syndrome.

The link between psoriasis and sport is a controversial issue. The topic has been poorly investigated, and nowadays there are many unsolved questions, dealing with the role of psoriasis in influencing the sporting habits of patients and, vice versa, the impact of sport activity on course, severity and extent of the disease, with particular regard to the indirect benefits on cardiovascular risk and metabolic syndrome. Moreover, the role of physical activity on patients’ quality of life and the potential limitations on physical activity due to joint involvement have not been well elucidated until now. In this narrative review we will try to provide answers to these queries.

Male Wistar Rats

This study evaluated the chronic effects of the run and walk in the metabolic and cardiovascular parameters of a metabolic syndrome experimental model. Male Wistar rats were divided into 4 groups(n=8): Control (C),Sedentary Fructose (SF), Fructose Run (FR) and Fructose Walk (FW, n= 8). Metabolic syndrome (MS) induction was performed with D-fructose in drinking water for 18 weeks. The exercise training was initiated after the nineth week of treatment with fructose and was held for 8 weeks (60 minutes/day, 5 times / week). The FW and FR were performed on a treadmill (1 h/day; 5 days/wk for 8 wk), with ∼20% and 60% intensities respectively of the maximum speed in a maximal exercise test. Plasma glucose, triglycerides, insulin resistance, adipose tissue, blood pressure, heart rate, baroreceptor sensitivity and sympathetic and parasympathetic tone, were evaluated at the end of protocol. The results showed that run and walking decreased the adipose tissue (FR: 2.97±0.2; FW: 4.26±0.9; SF: 6.49±0.6; C: 3.23±0.2 g). The glycemia values remained within the normal range,(FR: 86.7±2.3; WF: 91.0±1.4; SF: 70.2±1.9; C: 84±2.3 mg/dl), however only the FR group decreased the triglycerides levels (FR: 133±8.8; FW: 159±10.2; SF: 220±6.3; C: 96± 4.2 mg/dl), and the insulin resistance (FR: 4.37±0.1; FW: 3.55±0.2; SF: 2.79±0.3; C: 4.86±0.3 %/min). The FR group showed a reduction in mean arterial pressure (FR: 111±4.5, FW: 125±4.1; SF: 137±2.6, C: 113±1.5 mmHg) and increased of bradycardic (FR 1.76±0.08; FW 1.31±0.10; SF 1.37±0.10; C 1.72±0.14 bpm/mmHg) and tachycardic response to BP changes (FR 4.02±0.32; FW 2.56±0.16; SF 1.97±0.15; C (and C 3.25±0.37 bpm/mmHg). Finally we observed that only the FR group showed an increase of the vagal tone (FR: 72.3±8.1, FW: 47.3±6.7; FS: 40.3±4.6, C: 60.7±6.5 bpm). In conclusion, our results suggest that training walk (FW), a practice widely recommended, is especially effective for the treatment of metabolic disorders, whereas controlled exercise (FR) seems to encompass hemodynamic and metabolic aspects. This application is easy and within reach of the majority of the population, indicating that this practice should be encouraged and may be effective in managing cardiovascular risk in MS as start therapeutic.
