Many athletes do not achieve success proportional to their potential possibilities precisely because they do not have sufficiently high achievement motive. The aim of this study was to examine the relationship between the Big Five personality traits model and achievement motive in athletes. The survey encompassed 301 athletes from the Republic of Srpska. We applied the Big Five Inventory and Achievement Motive Scale. A series of hierarchical regression analysis was used to examine the predictive contribution of personality traits to achievement motive and its components, after removing the impact of demographic variables on achievement motive. The obtained results indicate a significant predictive power of personality traits for achievement motive. The most powerful predictor of the total score of achievement motive was conscientiousness. By observing the components of the achievement motive, conscientiousness proved to be a significant positive predictor of all components of achievement motive. Other personality traits of the Big Five model have proved to be significant predictors of one or more components of achievement motive. The obtained results are important for researchers, in order to better understand achievement motive in sport, but also for sports coaches and selectors deciding on the athletes for competitions.","PeriodicalId":30424,"journal":{"name":"Fizicka Kultura","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75424698","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}

Ponorac, Amela Matavulj","doi":"10.5937/fizkul1902206b","DOIUrl":"https://doi.org/10.5937/fizkul1902206b","url":null,"abstract":"Hepcidin is a peptide that was discovered in 2000, it is synthesized in the liver and it goes into circulation. There are three forms of hepcidin, hepcidin-25, hepcidin-22 and hepcidin-20. The first form is the most studied and its role is the most significant. Hepcidin-25 is considered to be a major regulator of the absorption of dietary iron as well as its release from cells. It achieves its regulatory function by preventing the function of ferroportin, the major cellular iron exporter. Ferroportin is a protein whose function is to release iron from the cells on which it is located (macrophages, hepatocytes and enterocytes). Hepcidin-25 induces degradation of ferroportin, resulting in an increase in intracellular iron stores. It also reduces the absorption of iron from food and thus reduces the concentration of circulating iron. During physical activity, the concentration of hepcidin increases at an intensity of 65% VO2 max, and maximum values are reached at 90-95% VO2 max. Not only intensity, but also the volume of physical activity influence its concentration. Studies showed that hepcidin expression during physical activity is influenced by inflammation, iron status, erythropoiesis and hypoxia. It is considered one of the causes of anemia in athletes. There are potential methods for neutralizing hepcidin (monoclonal antibodies and antagonists) and reducing its expression (erythropoietin doping, which is forbidden in sport, anti-IL-6 antibodies, STAT and BMP modulators). Given its important role in iron metabolism, which is essential for the transport of oxygen in the body, it can affect sports performance. It is still the subject of many research.","PeriodicalId":30424,"journal":{"name":"Fizicka Kultura","volume":"29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81752199","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}

{"title":"Periodization models in the research of the muscle strength in athletes, theoretical-methodological reductions or non-critical positivism in sport-scientific periodics","authors":"M. Ćosić","doi":"10.5937/fizkul1902174c","DOIUrl":"https://doi.org/10.5937/fizkul1902174c","url":null,"abstract":"Periodization is a theoretical and practical construct of sports training that relates to the programming of training activities in mutually dependent periods of time in order to induce specific physiological adaptations. During training and competition processes, it is used to achieve results at the specific competition. The theoretical and practical foundations of the periodization process can also be studied from the aspect of its impact on biomotor abilities. In this context, the general position for the study of periodization include research covering the impact of different periodization models on muscle strength (the subject of this paper). Based on an analysis of the content, meaning, methodological orientation, and conclusion within a selected number of published studies/papers, it cannot be ascertained whether periodized training models, in the muscle strength area, give better results than the non-periodized model, or which periodized model gives better results at all. The above-mentioned dilemmas regarding the subject of this work have also been confirmed in several review papers and meta-analyses. However, by examining the methodological and theoretical context of these studies, a number of dilemmas are evident, primarily those related to the sample of the subjects. Namely, none of the analyzed studies focused only on the athletes as a target group, but instead, the results of the research performed on athletes were analyzed in relation to a group of recreational or non-trained subjects. Also, there is a discrepancy in the terminology of the applied periodization models, which opens up the question regarding the existence of a clear theoretical concept and methodological-organizational construct that aims to achieve a competitive result. It can be assumed that a clear analysis of the original context of the phenomenon of periodization, harmonization of methodical and methodological steps in the process of learning, clear distinction towards existing definitions and terminology, resulted in the optimization of the learning process that will lead to recognition of the periodization model, which will result in optimization of the training-competitive preparations goals. Therefore, the problem of this paper derived from the theoretical and methodological inconsistency of the researchers in areas covering the influence of different periodization models on athletes' strength. The aim of the paper was to analyze and determine the facts of the methodological and theoretical construct of periodization, the conclusions of various studies, which can be said to - despite publication in important international journals - lead to confusion in the area of the conclusion about the influence of different periodization models on the strength of athletes. After examining more than 80 papers published in refereed journals, and by selection in relation to the theoretical-methodological context and the context of deductive conclusions, 10 studies have bee","PeriodicalId":30424,"journal":{"name":"Fizicka Kultura","volume":"53 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81023673","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 sample was made of 125 participants (female students) of III and IV year of Bachelor studies of FASPER. Research was conducted in a Methodical-research laboratory (MRL) in Faculty of sport and physical education, University of Belgrade in a time period 2012-2017, in accordance with standardized procedure of applying electrical multichannel bioimpedance method with body structure analyzer - InBody 720. It contained twenty (20) variables, eight (8) were basic and twelve (12) were derived. Based on BMI it's claimed that 77.60% participants has a normal body status, but the prevalence of overweight students (BMI 18.50) is 11.20%, with 4.00% participants who were significantly thinness underweight i.e. poorly nourished (BMI>17.50). According to the results it was concluded that even 96.8% of sample was not in line with ideal or optimal body structure profile. For example, 63.2% participants has some form of body mass deficits (average of 5.25 kg) with mostly muscle component deficit 78.4% (average muscle mass deficit is 4.28 kg) and with body fat component deficit 43.2% (average deficit of body fat is 2.01 kg). On the other hand, 33.6% participants has a form of surplus (average surplus in body structure is 9.44 kg) where even 54.4% has a surplus of body fat component (average level of surplus of body fat 7.48 kg). The results of 4D body structure model of female students from FASPER can be defined like this: 31.77 L of Total Body Water (53.37%), 8.50 kg of proteins (14.26%), 16.98 kg of body fat (27.10%) and 3.10 kg of minerals (5.18%). Beside the probability that the reason of bad nutrition behaviour of these students is the cause of their increasing fat depots it's also a fact that 69.6% of these students are physically inactive and 21.6% just occasionally active, which mean that 91.2% of students was physically non active person, could indicate a most possible reason of body fat component suficit and body muscle component deficit as a main body structure characteristics.","PeriodicalId":30424,"journal":{"name":"Fizicka Kultura","volume":"48 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75697083","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}

Having regard to the changes occurred in some segments of physical education, during the period of the full state sovereignty of the Republic of Serbia, the analysis included the following: legal framework and adopted documents, PE curriculum and program, physical education teaching conditions, educational standards, teaching staff, physical education exemptions and research in the field of physical education. The importance of physical education, which has been recognized in the legal framework, by the recommendations contained in the adopted regulations and measures, has not been implemented or practically applied. In this sense, an increased number of PE classes and uniform conditions for physical education teaching at the state level, i.e. throughout the country, should be set as a priority. The emphasis which has moved away from the curriculum and learning content towards the learning process and its outcomes, introduction of the mandatory monitoring, evaluating and recording of pupils' physical abilities and allowing pupils to be exempted only from a practical part of the PE course with an obligation to attend PE classes represent significant novelties within the subject bearing a new name (Physical and Health Education). It is necessary to assess the achievement level of educational standards, i.e. to examine the extent to which pupils have acquired knowledge and skills and developed their motor abilities upon completion of their compulsory education. Mandatory professional development of PE teachers aimed at acquiring new competences and strengthening the existing ones is important for the improvement of educational work. The research results have indicated that it is necessary to continuously monitor the prevalence of obesity and level of physical activity and motor abilities in pupils at the national level, as well as to promote healthy eating habits and encourage children to engage in physical activity and exercise.","PeriodicalId":30424,"journal":{"name":"Fizicka Kultura","volume":"52 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84836012","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}
