The development of the sports industry was impacted by the era of Big Data due to the rapid growth of information technology. Unfortunately, that has become an increasingly challenging Issue.
The ...purpose of the research was to analyze the scientific production of Big Data in sports and sports-related activities in two databases, Web of Science and Scopus.
Bibliometric analysis and topic mining were done on 51 articles selected after four exclusion criteria (written in English, journal articles, the final stage of publication, and a detailed review of all full texts). The software tool used was Statistica Data Miner.
We found that the first articles appeared in Scopus in 2013 and WoS in 2014. USA and China are countries which produced the most articles. The most common research areas in WoS and Scopus are Public environmental and occupational health, Medicine, Environmental science ecology, and Engineering.
We conducted that further research and literature review will be required as this is a broad and new topic.
The purpose of the research was to analyse the injuries of primary school children in the framework of organised sports activities at school and in clubs or associations, and in leisure time without ...professional guidance.
We surveyed 631 participants, of which there were 282 boys and 349 girls from eight Slovenian primary schools. Frequencies were calculated and a Chi-square test was performed.
In physical education (PE) at school, 32% of the participants were injured in one school year, and there were no statistically significant differences in the number of injuries according to sex (p=0.18) and age (p=0.12). Most injuries were recorded in the lower extremities (50%), in the form of wounds. The participants were injured less often in PE at school than in a club or association, and more often than in their leisure time. The participants were absent from PE classes for longer after an injury in a club or association than in PE, while no significant differences in absences after injury were found. At school, the participants were most often injured in ball games, boys in football (43%) and girls in volleyball (19%). In activities in a club or association, we recorded the most injuries in boys in martial arts (18%) and dance for girls (19%). In their leisure time, boys suffered the most injuries from football (26%) and cycling, while girls suffered the most from running and rollerblading.
In the last ten years, the number of injuries in PE has increased in Slovenia. Based on the obtained results, we propose measures to reduce injuries and thus encourage more sports activities among children and adolescents, while ensuring their safety.
Introduction: Prior research generally confirms the importance of endurance exercises in preschool period and suggests shorter and less intensive exercises. However, little research has been ...conducted to show and evaluate different types for developing endurance in preschool period. Our research aims to find out which type of exercise is more suitable for developing endurance for a preschool age child compared to an adult, taking into account developmental characteristics.
Material and methods: A total of 69 preschool children (40 children aged 3 years and 29 children aged 5 years) were included in the study. We measured their heart rates during two types of endurance exercises (uninterrupted walking vs “method of game”). We compared the average heart rate and the actual frequency curves.
Results: Endurance exercise according to the “method of game” allows the child to adjust the effort more individually compared to uninterrupted walking when both exercises are performed with a group of pre-school children. A comparison of heart rate curves showed that when children partook in the “ method of game”, they achieved different heart rate values at the same time. A further analysis of heart rate with 5 selected “time stamps” between the two exercises showed that children achieved statistically significant higher heart rates when performing the “method of game” (1’: Z = 2.20; p = 0.028, r = 0.19; 3 ‘: Z = 4.64; p = 0.00, r = 0.39; 5’: Z = 3.23; p = 0.001, r = 0.27; 8’: Z = 3.82 p = 0.00, r = 0.32; 13 ‘: Z = 3.33; p = 0.001, r = 0.28). The comparison of the mean heart rate values over the entire 13-minute time interval between the execution of the “method of game” (M = 143, SD = 14) and uninterrupted walking (M = 132, SD = 9) was statistically significantly higher in favour of the “method of game” (Wilcox test: Z = 5.83, p = 0.00, r = 0.24). The Mann-Whitney-Test showed that 3-year-old children achieved statistically significantly higher average heart rate during the “method of game” (Z = -2.34 p = 0.020, η² = 0.08) as well as during uninterrupted walking (Z = 3.17 p = 0.002, η² = 0.15). No statistically significant differences between boys and girls were confirmed.
Conclusions: Based on the results obtained, we believe that endurance exercise according to the “method of game” is more suitable for a developing preschool child than uninterrupted walking. The “method of game” also allows the simultaneous implementation of endurance exercise in heterogeneous groups, since the children adapt to the effort themselves, regardless of age. We believe that other types of endurance exercises should be researched and all age groups of preschool children should be included in the research.
Background: Stress is an inevitable phenomenon of students’ way of life nowadays. In particular, stressors are associated with study obligations and interpersonal relationships. In a time of rapid ...social changes, the problem of stress among young people is highly dynamic and complicated; therefore, academic studies and research regarding this subject are among the most important tasks of society. Our study aimed to analyse the stress and coping strategies among the students of selected faculties of the University of Ljubljana.Methods: We surveyed 622 students of the first and third year of six faculties of the University of Ljubljana, of which 40.5% were men and 59.6% women. The questionnaire was summarized according to the questionnaire used in the project “Risk Factors for Non-Communicable Diseases in Adult Population of Slovenia” was used in our study. The data were processed with SPSS. The basic statistics were calculated, and the hypotheses were checked at the level of 5% of the statistical risk (p ≤ 0.05) using the Chi-square test.Results: The survey showed that most students (46.8%) feel stress occasionally, 30.4% of them often, and 4.7% every day. The students of the Faculty of Medicine are more affected by stress than other students are, especially in comparison to the students of the Faculty of Sport. Women suffer from stress more than men do. A total of 82.2% of the students claimed the burden of study as the reason for tension, stress and a feeling of heaviness. Among them, most students were from the Faculty of Medicine and the least were from the Faculty of Sport; most of them were women. The students of the Faculty of Mechanical Engineering and the Faculty of Medicine study and learn continuously. Outside the examination period, 38.5% of students sleep only 5 to 6 hours per day. Only 12.8% of students can easily handle stress, 70% of them handle stress with some effort and 16.5% of them with great effort; among them, students of the third year and men cope with stress better than others do. As a coping strategy, a large majority (72%) of students mention sports activity, mostly students of the Faculty of Sport, and the least students of the Faculty of Education. Only 5.2% of students never engage in sport; most are active in sports from 3 to 5 days a week, from 30 to 60 minutes.Conclusion: The study highlighted the problem of stress and coping with it with students from selected faculties of the University of Ljubljana. The survey has shown a high prevalence of self-reported stress, with the vast majority of students reporting physical activity as the most used method of coping. There were significant differences with the corresponding confidence level 95% in terms of gender and faculty. Further research and the implementation of effective measures could improve the quality of life of students, which would later also contribute to reduced levels of burnout in the workplace, as young people as students would be better aware of this problem and knew the appropriate preventive measures.
As cardio-vascular diseases are the leading cause of death worldwide, establishing measures to improve cardiovascular health is of crucial importance. Exercise plays an essential role in cardiac ...rehabilitation of patients with coronary artery disease (CAD), in whom an evaluation of the cardiorespiratory fitness (CRF) is necessary. CRF of CAD patients could be assessed using 6-min walk test (6MWT), and the results interpreted by using Enright-Sherill prediction equation which has mainly been designed and evaluated for a healthy population. Hypothesizing that the Enright-Sherill prediction equation might not be best suited for CAD patients, our aim was to reevaluate this equation in CAD patients, and potentially establish a more accurate 6MWD prediction equation to be applied in these patients.
6MWD was measured in a cross-sectional study in 67 CAD patients (44 women) who were members of the Coronary club Ljubljana, Slovenia. In addition, the predicted 6MWD was calculated for men and women using Enright-Sherill gender specific regression equation. Multivariate regression analysis was used to obtain a new prediction equation, and the agreement between the measured and the predicted 6MWD analyzed using the repeated measures ANOVA.
Men achieved 451 ± 122 m and women 485 ± 69 m without significant differences between sexes (F = 0.022,
= 0.882) when adjusted for age, height, body mass, and waist circumference. When comparing the measured (473 ± 91 m) and the predicted (422 ± 57 m) values of 6MWD in CAD patients we found that the Enright-Sherill prediction equation significantly (F = 27.734,
< 0.001) underestimated the 6MWD by 52 ± 81 m. A significant regression equation was established F (3,63) = 44.663,
< 0.001, with a
of 0.680 where 6MWD equals 1,057 m-4.966 x age (years)-0.614 x WC (cm)-68.629 x NYHA class.
The results of this study stress the importance of regular and actual walking ability testing in patients with stable CAD to obtain their CRF, rather than simply predicting it from regression equations obtained from non-representative or non-comparable samples. Our developed prediction equation warrants additional validation and may represent a good substitute for currently used predictions obtained from a healthy population.
The objective of the research is to identify the different factors of Lebanese culture that interfere with weight loss therapy and assist the field of nutrition in homogenising in a standardised ...manner the protocol of Medical Nutrition Therapy (MNT). The first part of the study is based on a literature review, and, in the second part, quantitative analysis was used. The research was conducted on 514 Lebanese adults via questionnaire. The analysis was performed with the AMOS (Version 22, IBM®, Amonk, NY, USA) statistical tool. For the analysis of correlations, chi-square and non-parametric tests were used. Variables affecting weight loss management were identified with the aid of seven hypotheses using structural equation modelling (SEM). Body shape and Body Mass Index (BMI) were found to be inter-related to cognitive behaviours toward food, lifestyle practices, medical conditions, food and beverages. In parallel, and based on the research results, younger adults, in particular women, have better BMI and look better in terms of body shape. Ageing has a direct impact on weight gain. Older people have a lower activity level, which is more prevalent among women, and they also prefer to eat typical Lebanese food. Habits, such as smoking, drinking alcohol, are directly related to obesity and some medical conditions. Low physical activity influences the problems related to body shape. For further studies, one should also include types of physical activities in terms of intensity and number of hours. This would assist the study in being more specified and credible toward the effect of exercise on weight loss management.
Obesity is an increasing worldwide problem, and it is common in women with polycystic ovaries syndrome (PCOS). It is well known that women with PCOS have lower chances of spontaneous conception as ...well as lower success with IVF procedures. The mechanisms by which obesity causes lower fertility are not yet fully understood. The aim of the present study was to determine the effect of a lifestyle intervention weight loss program on the expression of the endometrial genes during the window of implantation (WOI). For this purpose, 15 infertile women with obesity and PCOS were included in the study. Endometrial samples were taken during the WOI before and at the end of the program, and RNASeq analysis was performed. There were no significantly differentially expressed genes before and after the weight loss program. We then compared the results of our study with previously published studies on markers of endometrial receptivity. The biomarker genes that were found to be down-regulated during the WOI in previous studies were more down-regulated after the weight loss program in the present study. Furthermore, 25% of the women who achieved the desired 5% or more weight reduction conceived spontaneously. Our study shows that weight loss might positively impact endometrial receptivity. which may lead towards the improved fertility of obese women with PCOS.
Abstract
Introduction
Injury registration is an important first step of the musculoskeletal injury (MSI) prevention process that helps establish the magnitude of the problem and focus prevention on ...the body parts that are most frequently injured. However, an injury definition used in that process may influence the reported prevalence of MSI, causing some injuries to be under-reported which in turn alters the prevention efforts. The primary goal of our study was to identify the 10-year prevalence of MSI in members of the Slovenian Armed Forces (SAF), to help plan and implement preventive measures for the reduction of MSI. Our secondary goal was to compare MSI data collected using two different approaches. The first one was prospective approach where only time-loss injuries were collected during a 10-year period, and the second one was a cross-sectional approach where at one point in time soldiers were asked about any musculoskeletal complaint.
Materials and Methods
The study was an introductory part of trial that was registered in the U.S. Clinical Trials Registry (clinical.trials.gov) under the identifier number NCT03415464. For the retrospective analysis, injury data from the Department of Safety and Occupational Safety of the SAF were used for a 10-year period (2006–2015) where only injuries that cause a soldier to be absent from duty for three or more working days are registered. For cross-sectional analysis, 129 members (N = 129) of an infantry SAF regiment (118 males, 11 females) volunteered to participate in the study. A modified Oslo Sports Trauma Research Centre (OSTRC) injury report form was used to collect injury data about current musculoskeletal complaints.
Results
The 10-year prevalence of MSI in SAF was 4.9%, with significantly (p = 0.0004) lower prevalence in females (3.1%) than males (5.4%). The most frequently injured body parts were ankles (23%) and knees (21%). The cross-sectional analysis has shown a much higher MSI prevalence of 48.8% (50.8% in males and 27.7% in females), demonstrating that some MSIs are probably under-reported. For all reported injuries in a cross-sectional analysis, a previous injury was a strong and significant injury risk factor (p < 0.001 for all instances).
Conclusions
To the best of our knowledge, this is the first comprehensive analysis of MSI among SAF members showing that the currently used injury surveillance system in SAF, that reports only the prevalence of time-loss injuries (4.9%), is probably underestimating the true and overall MSI prevalence (48.8%) in SAF members, suggesting a need for a better injury registration process. Based on the most frequent injury locations, preventive measures in SAF should focus on knee and ankle injuries in males with previous lower limb injuries. A best preventive approach would probably be to train smarter and harder to develop the physical capability to better protect against those injuries.

The aim of the study was to determine whether obstacle course and circuit training areefficient teaching methods as forms of exercise in terms of their intensity, monitored by usingenergy expenditure ...measuring devices. The key differences in energy expenditure between thetwo teaching methods were examined. The BodyMedia SenseWear equipment for measuringenergy expenditure was used to acquire data from two practice sessions. A sample ofparticipants included 24 five-year-old children from one kindergarten in Ljubljana, althoughcomplete data from both afternoon practice sessions was obtained only from 12 children. Thestudy has shown that obstacle course and circuit training are adequate teaching methods, asmoderate to vigorous intensity was achieved with both methods when practicing the ABCs ofgymnastics. The average energy expenditure has exceeded 7 MET in the main part of twopractice sessions for both obstacle course and circuit training. The results showed nostatistically significant differences in energy expenditure between genders or the specificteaching method used.
The performance of a pilot also depends on the pilot's personality profile and their stresscoping style. In our study we aimed to analyze, by means of the Big Five Questionnaire (BFQ) and the Coping ...Responses Inventory (CRI), the personality profiles, stress-coping strategies and the relationship between them among Slovenian military pilots. The study involved 120 respondents: 30 of whom were military pilots in the experimental group, while the other 90 were in the control groups. The control groups included sport pilots, the general population and soldiers with no involvement in aviation. The members of the control group were selected with regard to the characteristics of the experimental group members, so that both groups were equivalent in terms of relevant factors (e.g. gender, age, health state, level of education etc), thus participating in a study of equivalent pairs. A statistical analysis identified statistically significant differences between the groups in the following BFQ dimensions: energy, conscientiousness and emotional stability; in the dimensions of CRI 'cognitive avoidance' (cognitive effort to avoid realistic consideration of a problem); and 'emotional discharge or emptying' (behavioural attempts to alleviate tension by venting negative emotions). Results revealed that certain personality characteristics were differentially and significantly related to specific stress coping strategies adopted by military pilots.
