“…Additionally, the stress arising from exercise stimulates the neuro-endocrine axis, promoting greater synthesis and secretion of catecholamines by the adrenal glands. Such hormones are responsible for the migration of these cells into the circulation, causing an acute eff ect of increased absolute counts of circulating leukocytes, lymphocytes, neutrophils, and monocytes (Dias, et al, 2017), just as occurred in the present study. While catecholamines induce acute rise in leucocytes, cortisol has a late eff ect of inhibiting mitogenesis and lymphocyte functionality, promoting immunosuppression and increasing the incidence of URIs, and consequently, lowering the volume and quality of training among athletes (Keaney, et al, 2018;Pedersen & Hoff man-Goetz, 2000).…”

The aim of this study was to evaluate the effects of a day with two separate training sessions (morning and afternoon) of rhythmic gymnastics on erythrocytes, leukocytes, muscle damage, oxidative stress, and hydration of Brazilian team [age 17.7 (±1.1) years; body height 165 (±0.5) cm; body mass 49.7 (±4.2) kg]. Heart rate and session-ratings of perceived exertion were used to monitor training intensity. Blood samples were collected immediately before (M1) and after (M2) the training day for analyzing erythrocytes, leukocytes, plasma creatine kinase activity, lactate dehydrogenase, alanine aminotransferase, aspartate aminotransferase, ferric reducing ability plasma, thyroid-stimulating hormone, and free T4. Saliva was collected for cortisol analysis. After 24 hours rest (M3), blood collection was performed to analyze creatine kinase and lactate dehydrogenase. The moderate-intensity training day induced significant elevations of total leukocytes (5,163.3 to 9,617.8), lymphocytes (1,752.7 to 2,729.7), neutrophils (2,873.9 to 6,163.6), monocytes (255.7 to 519.1), platelets (280,000.0 to 300,666.7), aspartate aminotransferase (13.1 to 25.6), lactate dehydrogenase (102.5 to 249.1), thyroid-stimulating hormone (1.0 to 3.2), and ferric reducing ability plasma (136.8 to 165.4), as well as significant reductions in red cells (4,691,111.1 to 4,497,777.8), hematocrit (42.1 to 39.3), and hemoglobin (12.9 to 12.5) at M2. There were also significant increases in creatine kinase (144.2 to 519.3) and lactate dehydrogenase (102.5 to 538.2) at M3. The average dehydration rate was 1.3%. A moderate-intensity day of training in rhythmic gymnastics of 8h21min duration caused hemolysis, leukocytosis, muscle damage, redox status perturbations, and insufficient hydration status. These findings show that athletes are exposed to physiological vulnerabilities that can possibly harm their performance and health.

“…At the edge, marginal leukocytes are located due to the plasma's viscosity and shear force that makes them dislocate with a lower speed that the circulation pool. The catecholamines elevation promotes hemodynamic changes inducing the marginal leukocytes pool inside the blood vessel to migrate combined with the leukocytes in the middle of the vessel, justifying the development of a neutrophil leukocytosis associated with a reduction of monocytes, lymphocytes and eosinophils reported here [19].…”

Introdução: Diante das alterações metabólicas advindas do esporte e as consequências da superação dos limites individuais nos esportes coletivos de elite, faz-se necessária a compreensão bioquímica dos fenômenos ocorridos nessa modalidade a fim de minimizar danos, aperfeiçoar o desempenho atlético e fornecer protocolos mais adequados para cada esporte e indivíduo. Objetivo: O presente estudo objetivou analisar o metabolismo de atletas profissionais durante o treinamento mediante determinação de biomarcadores sanguíneos e urinários de proteólise, lipólise, hemólise e microtrauma muscular. Métodos: A avaliação foi realizada com 12 atletas que participam na série Ouro da liga de futsal. Todos foram submetidos a um protocolo padrão de treinamento e amostras de sangue e urina foram coletadas em repouso e 15 minutos após a sessão de treinamento. Resultados: A análise estatística dos resultados mostra um aumento significativo (p < 0,05) nas contagens relativa (células/ %) e absoluta (células/μL) de neutrófilos, bem como na concentração sérica de ácido úrico, colesterol total e frações HDL, ALT, LDH e CK-MM. Por outro lado, apresentaram uma diminuição estatisticamente significativa (p < 0,05) na concentração de magnésio, glicose, ureia urinária, contagem relativa de linfócitos, contagem absoluta de monócitos e eosinófilos (células /% e células/μL). Conclusão: Os resultados aqui obtidos permitem concluir que a compreensão bioquímica pode minimizar dano muscular, aperfeiçoar o desempenho atlético e oferecer formação de protocolos mais adequados para cada esporte.

“…Maleev et al aimed to assess the body reserve of skiers developing local area muscular endurance (LRME), static exercise, and resistance to hypoxia and described a regression model comparing key indicators of morphofunctional and metabolic status in athletes [5]. Dias et al study focused on reviewing the interaction between immunological parameters and overtraining syndrome, and the correlations between exercise, immune system, and susceptibility to URTIs were assessed primarily in individual and endurance exercise [6].…”

Cross-country skiing is one of the most important competitive events in the Winter Olympics, and it is also the earliest competitive sports event in China’s winter snow events. However, due to the influence of factors such as economic development, climatic conditions, and regional resources, cross-country skiing has developed slowly in China and is still in a relatively backward position compared with developed countries such as Europe and the United States. In this paper, the modeling and analysis of the attitude calculation system is proposed, and the attitude recognition technology is applied to the high-intensity resistance training system of cross-country skiing. Several training elements such as special endurance training goals, training content, training methods, and training monitoring are presented. It demonstrates the rationality and feasibility of the high-intensity resistance training system for excellent cross-country skiers in cross-country skiing and arranges the strengthening training of the upper and lower limbs and waist and abdominal muscles of the athletes in a targeted manner. For 6–9 times a week, each endurance training is about 1–4 hours or strength training is about 15–90 minutes. The fastest time for men is 31 minutes 29 seconds 21, which is 1 second 88 higher than that before training, and the average score has improved by 6 seconds 80; the women’s fastest time was 24 minutes 06 seconds 21, which was 4 seconds 22 higher than that before training, and the average score increased by 7 seconds 70.
