This resulted, as a consequence, in a remodelling of the lifestyle;in this scenario the correct nutrition combined with regular physical activity becomes fundamental for health. Although the sedentary lifestyle of a few weeks involves risks such as lowering the immune system, it favours overweight and obesity, high blood pressure, metabolic disorders, depression and anxiety, and in some subjects they react to the risk of onset of cardiovascular disease, diabetes and other diseases. The importance of healthy lifestyle is crucial to prevent also viral infection. Indeed, as reported by many data literature, during lung infections, IL-6 and TNF-a create the pathway between adipose tissue and lung system demonstrating the important involvement of adipose tissue in lung diseases. In obese condition, adipose tissue endocrine function is altered. There is an imbalance in the production of pro-inflammatory cytokines such as IL-6 and TNF-a and anti-inflammatory mediators such as IL-10. In the light of these evidences, the immune response is influenced by nutritional status and by physical activity which are able to reduce pro-inflammatory mediators and increase anti-inflammatory mediators such as IL-10. In addition, the power of viral infection is influenced by host predisposition. For these reasons, a correct lifestyle, and physical activity are a valid strategy in the prevention and treatment of not metabolic diseases also of inflammatory diseases © Faculty of Education.

In order to contribute to the young talent identification and selection of sports specialization, the aim of this STROBE-based cross-sectional study was to determine the morphological characteristics (MC), body composition (BC) and maturity status (MS) of U16 athletes from this subregion (7 municipalities). Eighty-one young athletes (66 weightlifters, 15 boxers) with at least one regional-competition of experience participated (33F; 48M; 14.9 ± 1.4 years; 62.28 ± 16.6 kg; 162.8 ± 9.9 cm). After parental informed consent, ISAK-standardized anthropometric data were collected during a youth sports championship. Athletes were subdivided in clusters using the PAM (k-Medoids clustering) and the bottom-up agglomerative (hierarchical clustering) algorithms. Both clustering methods were based on 55 variables that encompassed MC (raw variables, indices, somatotype), BC (five-compartment model, %BF-equations, ΣS) and MS (maturity offset, PHV, inter alia). The number of clusters was predefined as k = 2 since was the best solution according to 18 criterion-algorithms (100 bootstrap simulations). Non-parametric tests showed significant differences between sex, sports, municipalities and clusters for certain analysed variables. Internal validity of the clustering showed that sport type might explain the variation in the data; thus, it is noteworthy reasonable to recommend the implementation of unsupervised machine learning strategies along with other supervised methodologies in the identification and characterization of young talents and early sports specialization in Colombian athletes with Olympic projection but further research and support is needed.","PeriodicalId":221164,"journal":{"name":"Journal of Human Sport and Exercise - 2020 - Summer Conferences of Sports Science","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126005961","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of the study was to develop a system of realization step exercises in home conditions using the independent calorimetry during the period regime of self-isolation and to prove its effectiveness on the indicators of body mass index of the people. Study participants: 62 women and men between the ages of 18 and 45 who have problems with being overweight. Interventions: The study was being conducted in home conditions during 60 days. During the experiment the participants independently carried out the calorimetry, taking into account the consumed calories during the day and burning kilocalories while doing step exercises and another physical activity. For carrying out the calorimetry during the day a formula was developed due to available and simple counting: «N = 0.00168 - 0.098/P», where N - the amount of burning kilocalories per one heartbeat per one kg of body mass, P - heart rate per minute. Main outcome measures: It is defined out that the introduction of step exercises in home conditions with the use of independent calorimetry to the author's system has made a significant impact (p <.05) on body mass index of participants. Findings. In the presented study, for the first time, the regularities of increasing the burning of kilocalories in people at various levels of intensity depending on their body weight were experimentally revealed. © Faculty of Education.
