The study subjects were 380 players who took part in the 2018 Women’s Youth World Handball Championship. The independent variables were the relative age effect and the number of goals and shooting effectiveness of each type of shot. The dependent variables were the player’s position and the team’s final classification. To investigate the relationship between the RAE and the team’s final classification, player’s position, goals scored, and shooting effectiveness, contingency tables were drawn up and subjected to a chi-squared test. The dependence of the differences in goals and shooting effectiveness on the team’s final classification and the player’s position was studied by means of an ANOVA with a Tukey post hoc test. For the sample overall, there was no RAE, only an association between the classification and the year of birth, with more players born in the senior year in the teams ranked from 1st to 8th place than in those classified from 9th to 24th place. The teams classified from 1st to 4th had more significant numbers of several variables. There were differences in goals and shooting effectiveness, depending on the player’s position.","PeriodicalId":18942,"journal":{"name":"Montenegrin Journal of Sports Science and Medicine","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85073294","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}

A number of similar studies have been conducted in other parts of the world that investigate the knowledge, attitudes, and practices of athletes about doping. The results of those studies cannot entirely be extrapolated to elite Turkish athletes. Therefore, this study aimed to investigate elite athletes’ current knowledge of appropriate drug use, doping and use of supplements, and to explore the need for further education on these topics. A total of 202 Turkish athletes participated in this descriptive cross-sectional study. The data were collected through a questionnaire. A five-point Likert scale was used for questions. The most commonly used over-the-counter medications by athletes were painkillers (78.2%). A remarkable proportion of athletes considered painkillers (41.1%), protein powder (43.1%), and caffeine (41.1%) to be prohibited drugs. According to the athletes, physicians (84.6%) and coaches (78.6%) were the two most frequently used sources of information, and 87.6% of the athletes found the physician to be the most reliable source of information. Elite athletes have poor knowledge about doping in Turkey. There is an urgent need for educational anti-doping programmes to address the knowledge gaps observed amongst athletes in this study.","PeriodicalId":18942,"journal":{"name":"Montenegrin Journal of Sports Science and Medicine","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79730852","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}

Twelve well-trained young male basketball players with age 17.58±0.5 years, body mass 87.73±9.82 kg, and height 193.75±7.02 cm were voluntarily involved in the study. All participants were grouped randomly as sand and wooden training groups. A six-week plyometric training programme was performed on the sand and wooden parquet surfaces. Anthropometric measurements and physical performance tests; vertical and standing long jump, box agility, and 30m sprint tests were performed. Data were collected before and after six weeks of plyometric training and were analysed using ANCOVA. The results indicated that the plyometric training programme significantly improved jumping, agility and 30m sprint performance for both groups. Significant differences were found between the post-test mean values of two groups in the box-drill agility and 30m sprint test scores (p < .05). The results of this study suggest that while the plyometric training performed on a wooden or sand surface does not cause a different effect on the improvement of jumping performance, plyometric training on the sand surface may be a more effective training surface to improve the agility and sprint performance of young players.","PeriodicalId":18942,"journal":{"name":"Montenegrin Journal of Sports Science and Medicine","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77679303","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 main finding was that students under the elective condition felt more competent and motivated compared to those in the compulsory condition. They were also more physically active. When offered as electives, tertiary level physical activity education courses may be limited in reach, primarily attracting those who would likely be physically active without any such coursework.","PeriodicalId":18942,"journal":{"name":"Montenegrin Journal of Sports Science and Medicine","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79355307","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 most common research topics were identified, their methodologies were described, and the evolutionary tendencies of this area of research were systematized. Within a systematic review of the Web of Science TM Core Collection, PubMed, and SportDiscus databases, according to the PRISMA guidelines, the following keywords were used: “handball”, each one associated with the terms: “match analysis”, “performance analysis”, “notational analysis”, “game analysis”, “tactical analysis”, and “patterns of play”. Of the 245 studies initially identified, 28 were fully reviewed, and their results were analysed. Studies that meet all the inclusion criteria were organized according to the research design as descriptive, comparative, or predictive. The results showed that most of the studies use the statistics available through the tournament organization; some researchers have attempted to find some association between cause and effect in different contexts. The studies focused their analysis on four main variables of performance: total shots and finals, end match outcome, Time Outs (TTos), and the relationship between home advantage. This systematic review can provide useful information on potential lines of research for performance analysts in the field of handball match analysis.","PeriodicalId":18942,"journal":{"name":"Montenegrin Journal of Sports Science and Medicine","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82364886","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}

This study aims to investigate the chronic effect of high-intensity interval training (HIIT) on cross-sectional areas and muscle denervation genes, interpreted in the plantaris muscle atrophy of aged rats. Twenty-eight aged and young rats were divided into four different groups, including exercise and control. The training protocol included six weeks of HIIT. Animals were sacrificed 48 hours after the last training session, and the plantaris muscle was removed. To measure Gadd45a mRNA and NCAM1mRNA, we used a real-time PCR technique. The cross-sectional area was measured with photomyography using an H&E technique. The results showed that ageing significantly decreased NCAM1 mRNA in the aged control group (p=0.0001) and exercise leads to a significant increase (interaction effect) of it (p=0.003). Gadd45a mRNA was significantly increased due to ageing (p=0.009), and exercise resulted in a significant decrease in that in the aged exercise group (p=0.04). The cross-sectional area in the aged control group was significantly smaller than in the young control group (p=0.046). In contrast to young groups, exercise could increase the cross-sectional area in the aged exercise group compared with the aged control group, but it was not significant (p=0.069). It seems that HIIT could improve ageing-induced muscular atrophy, although denervation-involved gene modification leads to an increase in the muscular cross-sectional area; therefore, it improves muscular atrophy due to ageing.","PeriodicalId":18942,"journal":{"name":"Montenegrin Journal of Sports Science and Medicine","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88800771","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}

Eight daily smokers (28.44 ± 3.94 years) and nine non-smokers (29.62 ± 3.46 years) were included. The subjects were not trained and performed continuous endurance exercise on a treadmill for 40 minutes at 70% of maximal heart rate. Venous blood samples were collected at baseline [preexercise (PRE)], at immediately after the exercise [post-exercise (POST)], at 2 hours after the exercise (2h), at 24 hours after the exercise (24h) to measure lactate dehydrogenase (LDH), creatine kinase(CK), creatine kinase-myocardial band (CK-MB), cardiac troponin T (TN-T), and myoglobin levels. A progressive increase was observed in all exercise-induced muscle damage parameters of the smoker and non-smoker from PRE to 2h. CK, myoglobin and T-NT levels of smokers were significantly higher than non-smokers at 24h (p=0.039, p=0.018 p=0.008, respectively). No significant difference was found between the smoking and non-smoking groups at all time points regarding CK-MB and LDH levels (p>0.05). Acute endurance exercise leads to more skeletal and myocardial damage in smokers compared to non-smokers. Smoking may increase the risk of cardiovascular events during both exercise and daily physical activity.","PeriodicalId":18942,"journal":{"name":"Montenegrin Journal of Sports Science and Medicine","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89894513","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}

Limited research in the last five years in Singapore shows that young children experience significant amounts of screen time from television, computers and other forms of mobile digital devices, even before primary school. For children, digital media use can aid with learning, but its overuse has inimical effects on learning and health. As digital media use in children increases faster than research on its impact, it is essential to develop a tool that can monitor changes in digital media habits of children over time. This study aimed to develop an online questionnaire for parents to report on the digital media habits of children. An online questionnaire bundle, Surveillance of digital-Media hAbits in earLy chiLdhood Questionnaire (SMALLQTM), organized into sections ((I) Digital-media use of parent and child, (II) Non-digital media behaviour of the child, (III) Parent and child information) was developed for the purpose of charting digital media use and changes over three years (2018, 2019, and 2020). The results showed that SMALLQTM has face and content validity and was practicable for Singapore. Furthermore, based upon a similar methodology for developing the SMALLQTM, the development of Child-SMALQ (Surveillance of digital MediA use in chiLdhood questionnaire) and Adolescent-SMALQ (Surveillance of digital MediA use in adoLescence questionnaire) are directions for future research.","PeriodicalId":18942,"journal":{"name":"Montenegrin Journal of Sports Science and Medicine","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81985006","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":"Research Quality Evaluation in Social Sciences: The Case of Criteria on the Conditions and Requirements for Academic Promotion in Serbia, Slovenia and Montenegro","authors":"S.

The University of Novi Sad, the University of Ljubljana, and the University of Montenegro were selected to be subjects in this study. The sources used for the analyses in this study were the official criteria on the condition and requirements for academic promotion at the abovementioned universities. The authors used a descriptive method with the consulting of competent sources and personal experiences. First, it is interesting to note that the universities in Serbia and Slovenia follow official documents at two levels: one at the national level issued by the relevant higher education council/agency and the second at the university level issued by the senate of each university, whose criteria are more strict in terms of quantitative requirements. However, this is not the case in Montenegro, where universities follow only the national criteria in the research quality evaluation. In each country, evaluation exercises usually recognize three fields, one of which is social sciences and humanities, which is concerned with an entire range of interdisciplinary and multidisciplinary scientific areas. Comparing the minimum standards for the appointment of university teachers, it is essential to highlight that Slovenian regulations are the most demanding, especially with regards to quantitative criteria, while Serbian and Montenegrin criteria are similar to each other; however, it is necessary to highlight that Montenegrin regulations contain some unusual criteria, such as the requirement that scientific research work must be achieved through one single-author paper published in an international journal for promotion to academic titles at all three levels (assistant, associate and full professor) in social sciences and humanities; however, this is not the case in other academic fields.","PeriodicalId":18942,"journal":{"name":"Montenegrin Journal of Sports Science and Medicine","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78752510","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 of this study was composed of 5,161 receptions, corresponding to 84 matches (179 sets) of the Men’s Beach Volleyball World Tour organized by the Fédération Internationale de Volleyball (FIVB). The sample included only confrontations between the first 30 teams of the World Tour (FIVB ranking). The variables studied were: a) manner of serve execution: standing, power jump serve, and floating jump serve; b) reception technique (bump, overhead, and other); c) zone of reception: the court was divided into 10 equal zones; d) reception efficacy; e) spike efficacy; and f) rally result: win, continuity, or loss. The bump reception involved the highest efficacy coefficient, the number of receptions that allowed all options, and it was the most used reception. The power jump serve was the type of serve that most limited the receivers. This limitation was found when the serve required the receivers to move. The same tendency was found in the reception of the floating jump serve and standing serve, although not in the interference zone. Reception efficacy has a direct relationship with spike efficacy and winning the rally. The reception is the foundation for building a team’s attack. The data found in the present study can be used as a reference to guide match analysis and practices in men’s performance-level beach volleyball.","PeriodicalId":18942,"journal":{"name":"Montenegrin Journal of Sports Science and Medicine","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90251497","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}
