Athlete’s heart is characterised by structural, functional, and electrical remodelling. During an exercise session, the heart increases the use of oxygen, which is associated with decreased vascular resistance in the lungs’ circulation. Left ventricular hypertrophy is an echocardiographic modification especially met in endurance athlete’s heart. Moreover, left atrial dilatation represents another important characteristic of endurance athletes. Electrical modulation in the athletic heart induces neurological modifications leading to sinus arrhythmia, bradycardia, early repolarisation, and first-grade atrioventricular (AV) blocks. Athletes' nutritional status involves the assimilation of macronutrients such as proteins, carbohydrates, and fats. Depending on the duration of physical exercise, ATP can be obtained in aerobic or anaerobic conditions. This systematic review aims to find correlations between different evaluative methods of cardiac adaptation and present the metabolism in performance athletes.

“…Systematic training in bodybuilding and powerlifting leads to an increase in cardiac output (CO), which, under conditions of physiological bradycardia and an increase in cardiac output is one of the criteria for saving heart resources. Strength athletes have another manifestation of functional remodelling of the heart -a decrease in the sensitivity of the myocardium to sympatho-adrenal influences [34]. However, with the use of anabolic steroids or the wrong construction of the training process in strength athletes, the degree of sympathetic modulation of the functioning of the heart and blood vessels increases, and the sensitivity of the executive organs of the circulatory system to the influence of catecholamines increases [35][36][37].…”

The greater omentum is one organ that can accumulate a large amount of adipose tissue. Adipose tissue plays a key role in the local immune response and contains a population of multipotent mesenchymal stem cells. The greater omentum contains mainly white adipose tissue. White adipocytes usually have one large lipid droplet that occupies most of the cell and relatively few mitochondria. The primary function of the white fat of the greater omentum is to store and release energy in response to changes in systemic energy levels. In addition, white adipose tissue is an important endocrine organ that produces hormones and biologically active substances called adipokines and regulates many physiological processes.The aim of the work -summarize the existing scientific data on the morphofunctional features of adipose tissue of the greater omentum and its role in the development of obesity and type 2 diabetes.Adipokines play important roles in regulating whole-body metabolism, including promoting insulin sensitivity, insulin resistance, and inflammation. Dysfunction of adipokines, lipokines and their ratio plays an important role in the development of obesity and type 2 diabetes. Obesity and type 2 diabetes are two diseases that in most cases share metabolic abnormalities; however, there are also differences. The development of obesity and associated metabolic disorders is facilitated by the plasticity of adipose tissue. According to some data, the growth of adipose tissue and changes in metabolic processes in it can be influenced by the level of vascularization of adipose tissue. However, recent studies show that in obese patients, the number of capillaries in visceral adipose tissue is reduced compared to non-obese individuals, and the degree of vascularization was almost the same regardless of the degree of obesity or changes in the metabolic profile. Morphologically, patients with obesity and type 2 diabetes have a significant increase in the size of adipocytes in visceral adipose tissue, but the changes that occur in adipose tissue are not the result of prolonged hyperglycemia and may be associated with genetic or epigenetic factors of patients. In obesity, the increase in adipose tissue occurs due to hypertrophy and hyperplasia, which explains the relative decrease in the number of vessels in adipose tissue.

“…Cardiac adaptations induced by high‐intensity training have been widely studied, particularly in strength and endurance athletes, as the nature of training interferes with these adaptations, 1‐3 of which right ventricle (RV) morphology and functions of the right atrium (RA) have received increasing attention 4‐12 . Due to the similarity of RV adaptations to training with those observed in arrhythmogenic RV cardiomyopathy (ARVC), some studies have associated adaptations induced by training with pathology 13‐15 ; however, D'Ascenzi et al published a systematic meta‐analytical review to establish normative references for the assessment of the right heart of competitive athletes, 16 since the normative references established by the American Society of Echocardiography (ASE) 17 are intended for the general population and may lead to misdiagnosis in athletes.…”

Our purpose was to investigate the association between right heart dimensions and muscle performance and cardiorespiratory capacity in athletes. We selected 90 men with a mean age of 33.0 ± 8.0 years: strength group (SG), 30 bodybuilders; endurance group (EG), 30 endurance athletes; and control group (CG), 30 healthy non‐athletes. Comprehensive echocardiography and radionuclide angiography allowed the cardiac evaluation. VO2peak was assessed by cardiopulmonary testing, muscle strength by the one‐repetition maximum test (1RM) and the relative strength (RS), and muscle endurance by the maximum repetitions test (MR) with 50% of 1RM. In SG was observed an association between right ventricle (RV) basal diameter and RS bench press (R2 = .188 β = 0.486 P = .017) and between right atrium (RA) area and MR leg press (R2 = .257 β = 0.143 P = .004). In EG was observed an association between RV basal diameter and VO2peak (R2 = .299 β = 0.026 P = .002) and between RA area and VO2peak (R2 = .417 β = 0.092 P ≤ .001). In conclusion, our data suggest that there is an association between right heart dimensions and muscle performance and cardiorespiratory capacity; moreover, muscle strength seems important for understanding cardiac adaptations to training.
