{"title":"SHOULD I REPORT ABUSE? - ATTITUDES TOWARD DOPING TESTING AND ANONYMOUS REPORTING IN THE WHISTLEBOWER PROGRAMME","authors":"Tanja Kajtna, Luka Zajc, Nina Makuc","doi":"10.52165/kinsi.29.2.68-82","DOIUrl":"https://doi.org/10.52165/kinsi.29.2.68-82","url":null,"abstract":"Despite all endeavours to prevent it, the use of performance-enhancing substances continues to occur in sports and social science research suggests that doping prevalence is likely much higher than what is found through testing. One of the ways to uncover doping violators is through reporting illicit drug use, through “doping whistleblowing” – the readiness to do so depends highly on the level of our moral development and the motivation to do so. It was exactly this method, which helped uncover some of the biggest doping scandals in sport in the past few years and our purpose in this study was to examine attitudes toward drug testing and anonymous reporting and see, if we can predict an athlete’s intention to report anonymously based on attitudes toward drug testing. 255 top athletes and coaches from Estonia and Slovenia-two small, athletically successful countries-participated in this study, 176 male and 79 female, 156 athletes and 99 coaches from team and individual sports. They filled out an attitudes questionnaire about drug testing and an anonymous report. The participants filled out a questionnaire online. We used t – test to compare subgroups of participants and correlation and linear regression to look for relations between doping attitudes and willingness to make an anonymous report. Comparisons of subgroups of participants revealed that female participants are more likely to believe that taking banned substances should be punished but are less likely to make an anonymous report. We also found that coaches seem to be better informed about the issue of doping than athletes and trust NADO more than athletes. We found several correlations between attitudes toward doping testing and those toward anonymous report and we tried to predict the willingness to make an anonymous report. We found several predictors, which were different for men and women. NADOs play an important role in creating conditions, which will enable people to report doping anonymously, but it has to be done both through education and through rigorous testing. This will ensure that whistleblowing can become an active part of the fight for clean sport.","PeriodicalId":43206,"journal":{"name":"Kinesiologia Slovenica","volume":"16 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135556721","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 predictions of doctors and experts in static apnea, long-distance diving and achievable depths have been exceeded. The aim of this research is to analyze this trend and determine the development curve for the best results in the world between professional apnea divers in pool disciplines over the last 20 years. The sample of subjects in this work consists of the three best world results of free-breath divers in pool disciplines (STA, DNF, DNY) from 2002 to 2021. The variables used in the research are dynamics without flippers (DNF), dynamics with flippers (DYN) and statics (STA) in men. The data was collected from the official websites of the International umbrella diving organizations - AIDA and CMAS. Collected data was processed using a method, algorithm and trend analysis program in the Statistica 13.0 software package. A polynomial regression analysis was used to analyze the development trend of the best results in a given year for each discipline. The coefficient of determination (STA Multi. R=0.77 p≥0.00, DYN Multi. R=0.87 p≥0.00, DNF Multi. R=0.90 p≥0.00) of the positive correlation of the results, while statistical significance was determined by the analysis as a consequence of the constant change in the results. According to the data obtained from the research, a linear increase in results in all three disciplines (statics, dynamics without flippers, dynamics with flippers) between 2002 and 2021 can be determined. According to the analyzed literature, important success factors are knowledge of certain physiological properties, the physical condition of the individual and the optimization of energy.","PeriodicalId":43206,"journal":{"name":"Kinesiologia Slovenica","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2023-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43662928","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}

One hundred and ninety-one games from the FIBA 3x3 Under-18 World Cup 2019 and the FIBA 3x3 World Cup 2019 were analyzed. Offensive plays were classified into three types according to their starting actions: check-ball offensive plays (CBOP), transition offensive plays (TOP), or offensive rebound offensive plays (OROP). Offensive plays resulting in a successful field goal or an earned free throw were considered successful. Pearson’s chi-squared test was used to compare the success rates of offensive plays between starting actions and between categories. The Benjamini-Hochberg method was applied to ensure a significance level of 0.05. Cohen’s w was calculated as an effect size for the chi-squared test. TOP occurred with the highest frequency (55.1-57.5% of the totals) in all four categories, followed by CBOP (28.1-31.2%) and OROP (11.9-14.7%). The success rates of OROP (39.2-49.2%) were significantly higher (p < 0.05, w = 0.07-0.14) than those of TOP (28.5-36.4%) and CBOP (32.1-35.0%) in all categories. Improving the success rate of TOP is crucial to increase the chance of winning a game because TOP accounts for more than half of the total offensive plays. While the incidence of OROP was the lowest among the three offensive plays, the success rate of OROP was higher than that of TOP and CBOP, indicating the importance of acquiring offensive rebounds in 3x3 basketball.","PeriodicalId":43206,"journal":{"name":"Kinesiologia Slovenica","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2023-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47184491","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 recently established altitude training method »sprint interval training in hypoxia« (SIH) requires individuals to perform multiple 30 s Wingate sprints under hypoxia, interspersed with 3–5 min recovery periods. As the execution of repeated supramaximal efforts in hypoxia does not seem to be compromised, it was hypothesized that SIH might further augment exercise performance compared to sprint interval training in normoxia (SIT). To elucidate the usefulness of hypoxia during sprint interval training for exercise performance a systematic review of the available literature was conducted. The PubMed, SportDiscusTM, and Web of Science online databases were searched for original articles – published up to March 2023 – assessing changes in exercise performance following SIH and SIT. Six studies (randomized controlled trials (RCTs)) were identified, evaluating SIH interventions lasting 2–6 weeks. Currently, the available scientific literature does not suggest that SIH additively augments exercise performance in comparison to SIT. The potential changes in anaerobic thresholds after SIH, but not after SIT require further investigation to fully elucidate the subsequent effects on exercise performance. Nevertheless, there is evidence to support beneficial peripheral adaptations known to increase the oxidative and glycolytic capacity, especially in type II, fast-twitch fibers, following SIH, but not SIT. These local adaptations could potentially enable superior improvement in exercise performance after long enough SIH training protocols. Future RCTs on SIH and, particularly, on the performance-related underlying mechanisms seem warranted.","PeriodicalId":43206,"journal":{"name":"Kinesiologia Slovenica","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2023-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42297577","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 is even more emphasized when officers perform tasks while carrying their occupational load (e.g., protective vest, weapon, radio, cuffs, etc.). The absolute weight of the equipment remains the same regardless of officer’s body size and weight, which is of importance for female police officers whose morphology is different than in males. This study investigated the associations between selected measures of body morphology and CODS among female police officers under two loading conditions. The sample consisted of 29 female police officers (age = 32.00±5.09 yrs, body height = 162.92±5.01 cm, and body mass = 70.88±13.42 kg). Anthropometric variables included height, weight, and body mass index (BMI), while body composition characteristics included percent body fat, (PBF), percentage of skeletal muscle mass (PSMM), and index of hypokinesia (IH). CODS was assessed using the Illinois agility tests under loaded (LIAT) (10 kg vest) and unloaded (IAT) conditions. Participants’ CODS times were significantly slower in the LIAT condition (p < 0.001). IAT correlated to BMI (r=0.479, p<0.05), PBF (r=0.647, p<0.001), PSMM (r=-0.655, p≤0.001), and IH (r=0.462, p<0.05). Similarly, LIAT was associated with BMI (r=0.446, p<0.05), PBF (r=0.651, p<0.001), PSMM (r=-0.672, p<0.001), and IH (r= 0.503, p<0.01). These findings highlight the need for developing specific physical training programs aimed at improving and maintaining healthy body composition levels among female officers if improved CODS is the goal.","PeriodicalId":43206,"journal":{"name":"Kinesiologia Slovenica","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2023-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48164931","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 purpose of the article is to highlight the rehabilitation of rowing athletes during the formation of respiratory rhythms in course of bone tissue prosthetics. The aspect of the restoration of disturbed breathing rhythms and the activity of the cardiovascular system is of particular relevance. Since disorders of the cardiovascular system usually take place when associated physical damage occurs, the issue of forming a model of medical intervention during operations and rehabilitation activities is of primary importance. The main research method was the experimental method. With its help, experimental measurements and analysis of the obtained results were carried out. The novelty of the study is determined by the fact that the formation of a system of rehabilitation measures should be determined by the requirements for the achievement of previously shown results. The authors determine the structure of the model, its practical application and the formation of a graphic model on its basis that will be used when replacing parts of the skeletal support. It was determined that this allows to form not only stable functioning support, but also the respiratory systems, and thus lay the foundation for the athlete’s further physical rehabilitation for practical activities and return to sports. The practical significance of the subject matter is determined by the need to form adaptive potential, which will allow athletes to maintain positive dynamics of performances in the future at the level of international competitions.","PeriodicalId":43206,"journal":{"name":"Kinesiologia Slovenica","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2023-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48796264","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}

However, no studies have investigated the effects of cognitive characteristics on performance in practice. This study aimed to determine the effect levels of the different variables of elite male orienteers (i.e., success rate, year of sports experience, short-term memory, visual memory, attention, and concentration) on their performance in two orienteering courses (sprint and memory courses). A total of 36 voluntary elite male athletes who had been orienteering for at least two years, over 18, with a mean age of 24.58±4.85 years and sports experience of 7.83±3.56 years participated in the study. The Cognitrone, VISGED visual memory, d2 attention, and serial digit learning tests were applied to all participants, respectively. All participants ran the memory and sprint orienteering courses at 72-hour intervals in a randomized manner. Afterward, the effects of the athletes’ cognitive performance and some characteristics on the course completion time were examined. According to the results of the linear regression analysis, the model’s independent variables that affected the winning time of the sprint course were the success rate, short-term memory score, and concentration (R= .505, R2= .255, F=3.193, p=.003, p<.01). Among these variables, the variable that predicted the winning time of the sprint course the most was the success rate (B=-244.25, Beta=-0.473, P=.015, p<.05). Year of sports experience, success rate, short-term memory score, concentration, and cog-correct response time were the independent variables affecting the winning time of the memory course (R=.620, R2=.385, F= 3.374, p=.000, p<.001). Year of sports experience was the independent variable with the highest effect on the winning time of the memory course (B=-6.718, Beta=-0.369, p=.029, p<.05). The factors affecting the sprint and memory courses' winning time were examined, and it was concluded that the orienteers' years of sports experience and successes affected the course winning time. These findings suggest that orienteering race performance is more related to the experience of transferring them to orienteering and creating tactical processes rather than the cognitive characteristics of orienteers.","PeriodicalId":43206,"journal":{"name":"Kinesiologia Slovenica","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2023-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49640528","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}
