Opis:
The aim of this study was to determine the technical performance profile of service reception with regard to execution and efficacy level according to level of competition in women’s volleyball. The sample of the study was composed of a total of 6,311 game phases from 187 sets in 48 matches played during season 2005–2006 by the following divisions: under-14, under-16, under-18, 2nd national senior division, 1st national senior division, and international senior division. The design of the study was a descriptive and inter- and intra-group correlational one. The variables studied included level of competition, technique used to serve, technique used to receive, zone where the reception was executed, and efficacy of reception. The results indicated that at higher levels of competition: a) there is higher efficacy in reception; b) number of errors decreases; and c) proportion of receptions that allow one or more attacking options for the receiving team increases. As level of competition increases, the effect of service on reception decreases, and receiving zones are more diverse. This study establishes the technical and tactical service-reception profiles in women’s volleyball, compares them, and establishes the dependence between variables to understand how the action changes throughout the levels of competition.

Opis:
From feminist and critical point of view sport has been a sexist institution. Despite the women empowerment in sport they are still trivialized and marginalized. Research also shows that sport organizations may be exceptionally opposed to women, valuing hegemonic masculinity. Therefore the aim of this article is to check whether gender inequalities occur in Polish sports organizations and what is the scale of those inequalities in comparison to international and British organizations. The study used methods of examining official documents (information generated by other empirical data from official documents of the organisation). The sample consists of 17 Polish, 17 international and 17 British sports organisations. The results of research showed that in Polish sports organisations there are working less women than in the international and British organisations, there are also less women in committees and women committees (if they have been established). More women work in organisations which represent women-orientated sports disciplines.

Opis:
The Olympic Games of 1936 in Berlin found sports and Olympic movement in the Second Republic of Poland at a stage of developing and strengthening its organizational structure. The most famous and honored sport newspapers were: “Przegląd Sportowy” from Warsaw and – published by “IKC” concern from Cracow – “Raz, Dwa, Trzy”. The circulation of both titles constituted more than 3/4 of the circulation of all the sporting titles in the Second Republic of Poland. In this paper reports of “Raz, Dwa, Trzy” correspondents of the Olympic Games and the capital of Germany were presented. The analysis of the reporting of the journalists of “Raz, Dwa, Trzy” from the The Games of the XI Olympiad in Berlin allows to conclude that the narration of the reports fully corresponded with the aforementioned Polish-German Press Agreement of the 7th October 1934 and its basic assumptions. At the same time it was in accordance with the appreciation expressed to German organizers by foreign correspondents. The relations of the correspondents from Cracow indicate that Hitler’s’ regimentation reached its goals also in this environment. Enormous sports and infrastructural investments in the Third Reich, together with incorporating the modern technology, high degree of social discipline and the penchant for order and cleanliness, so typical for Germans, found their expressive reflection in the pages of “Raz, Dwa, Trzy”.

Opis:
Despite many previous studies dealing with various aspects of physical activity in individuals with an amputation, the risk of injury in amputee footballers has not been assessed thus far. The aim of this study was to characterize the incidence and causes of sport injuries experienced by amputee football players. Furthermore, the incidence of injuries was stratified according to the players’ level of competitive aggressiveness and anger, and their role in the field. The study included 21 members of the Polish National Amputee Football Team, who have been followed-up for a period of 6 months. A total of 16 injuries were recorded, including three that required a medical consultation: luxation of the left elbow, adductor strain and ankle sprain. The group of injuries that have not been consulted with a physician included muscle strains (n = 4), abrasions (n = 3), bruising (n = 3), joint subluxations (n = 2) and luxation (n = 1). The injuries turned out to be more frequent in the lower limbs (n = 10) than in the upper ones (n = 6). The risk of injury turned out to be higher during trainings (n = 9) than matches (n = 7). Amputee football seems to be associated with low risk of injury, since only several bodily contusions were documented throughout the study period. The injuries occurred in 38% of the players; this makes amputee football a relatively safe discipline which can be recommended to physically disabled persons.

Opis:
Most athletes in order to achieve satisfactory results have to train long and hard. However, some of them, aiming at victory at all costs, resort to doping. The benefits of winning are relatively small when compared to the damage of the human organism caused by doping. The phenomenon has been present in cycling, athletics, boxing, football, weightlifting and many other sport disciplines for many years. In fencing only few instances of the use of illegal substances during the competition were revealed, which was reflected in Polish and foreign sports press. In many European countries the use of doping is regulated by the anti-doping rules, regulations and policies that define these practices as penal acts. In Poland the problem of doping was first regulated by the Act on Physical Culture of 1984 and 1996 as well as the he Act of 1985 on Prevention of Drug Abuse. The regulations of FIE fencing competitions, prepared on the request of Polish Fencing Federation on the basis of the FIE competition rules in the disciplinary regulations of competitions prohibited the use of artificial stimulants during or before the competition. The aim of this paper is to present the threats in modern sports with particular attention to the phenomenon of doping in fencing, as well as in social terms. It is a case study and a study of selected issues connected to doping in contemporary sports. The author poses the question whether the fencers often are tempted to support their bodies with doping in order to achieve better results than the representatives of other sports? What percentage of the fencers were using illegal stimulants? Is there is a problem of doping in fencing, and if so, what is its scale?

The purpose of this study was to design, validate, and test the reliability of an instrument to evaluate knowledge of nutrition, weight control and its risk. The instrument collects information regarding: socio-demographics and athletic status; basic knowledge of nutrition (the diet they follow, nutrients, supplements, energy balance, myths, hydration and habits); and weight control and risks (weight control, eating behaviors, and weight control habits). The design, validation, and testing of the reliability of the questionnaire were done in four phases: a) design and development of the instrument, b) content validation, c) instrument reliability, and d) concurrent validity. The results show that the instrument is suitable for measuring nutrition, weight control and risk knowledge in athletes. The instrument that was developed and validated in this paper can contribute to assessing how the athletes evolve through their different formation stages.

The purpose of this study was to determine what coaches of female athletes know about the female athlete triad. The sample involved 472 NCAA Division I coaches of female athletes. The variables studied were coaches’ knowledge and confidence about the triad and coaches’ characteristics (coach’s gender, age, type of coach, degree held, years of experience in coaching females, continuing education participation specific to the triad and/or triad components, and sport coached). Coaches’ knowledge of the female athlete triad is higher for coaches who have received triad education. No differences regarding knowledge of the female athlete triad were found by gender, degree, experience in coaching female athletes, or coach type. Higher knowledge was found in sports emphasizing low body weight compared to sports that do not emphasize weight. The article discusses the results’ implications and the need for future interventions in this population.

Aim: The purpose of the current study was to analyse the effect of life stress, competitive trait anxiety and sleep disturbance on injury susceptibility in football players. Methods: Participants were 67 male football players from different teams in Cologne ranging in age from 18 to 25 years (M = 21.09 years; SD = 2.69). Participants filled out four questionnaires: The Holmes-Rahe life stress scale, the sport competition anxiety test (SCAT), the Pittsburgh Sleep Quality Index (PSQI), and the Oslo Sports Trauma Research Centre (OSTRC) questionnaire on health problems. Results: Results suggest that while life stress may increase the injury susceptibility, competitive trait anxiety, and sleep disturbance have no effect on injury susceptibility. Concerning this descriptive data, 53.7 % (36/67) of the players stayed away from the football field for at least one week, and about 23.8 % (16/67) of them did not have any injury during this four months’ period. Conclusion: Our findings suggest that high life stress levels caused athletic injury; for these reasons the psychological dimension should be considered and adapted in the training. Although we found no significant correlation between competitive trait anxiety, and sleep disturbance on injury susceptibility, longitudinal studies are required to assess the effect of life stress, anxiety, and sleep disturbance on injury susceptibility.

Climbing is becoming more and more popular. During 2020 Olympic Games this discipline will be competed for the first time. Individualized diet plays a significant role among representatives of all sport disciplines. The aim of this research was to evaluate the correlation between the level of advancement of sport climbers, selected anthropometric indicators and diet composition. The study involved 36 women and 65 men practicing sport climbing who completed the food record and the survey on the most difficult climbing routes completed. Anthropometric measurements were collected. In the group of men statistically significant, positive correlation between the climbing level and the diet content of fiber, vitamin E, potassium, iron, zinc, and copper, was observed. In the group of women, a statistically significant positive correlation between the climbing level and the participation of vitamin C, potassium, magnesium and copper in the diet was observed. There was a positive correlation of protein, vitamin B2, B6, B12, D, phosphorus, magnesium, iron and copper content, and negative correlation between SFA content per 1,000 kcal of the diet and the climbing level of study participants. No statistical correlation was found between anthropometric parameters and advancement level.

The aim of this article is to make the assessment of physiotherapy use in the case of swimmers’ regeneration. A diagnostic survey was used as the method. Opinions from the author’s survey were considered and there were 30 high-class swimmers analyzed aged 15–27. The research was conducted in 2012 at the Floating Arena swimming pool in Szczecin. 100% of the surveyed swimmers benefit from regeneration after physical effort. The most common physiotherapist treatment in case of swimmers is dry classic massage – 86.7%. The water bath (63.3%), sauna bath (56.7%), whirl bath (53.3%), water jets/Scotch douche (43.3%) and hydro massages (30%) are the most common types of hydrotherapy. On the other hand, ultrasounds and cryotherapy are the least common treatments when choosing adequate types of regeneration, i.e. respectively 13.3% and 3.3%. The biggest amount of massages is performed shortly before start – 40%. Massage in 60% cases lasts 10 minutes. In 90% of the surveyed group partial massage is being applied, whereas only 3.3% of competitors take the overall massage. In case of 80% of the swimmers, massage is regarded as completely relaxing. For 77% of them it relaxes both physically and mentally. In case of 80% of the surveyed, it is regarded as the most efficient form of biological regeneration. 60% of swimmers say it is helpful to maintain readiness to start and to overcome fever (feeling of annoyance) or apathy.

Nowadays, because of irregular lifestyle, high level of stress dietary supplements (DS) are becoming more popular as a source of needful nutrients among millions of people all over the world. The main purpose of present study was to estimate prevalence of dietary supplement consumption in sport, motivation in DS usage and sources of information. Anonymous self-administered questionnaire was spread among students of medical faculty in the end of their fourth year of study. There were 218 students of the fourth year of the Medical Faculty, of which 60.1% were females and 39.9% were males. Males more often used or had been using dietary supplements than females. The most popular dietary supplement was whey protein. The most common aim among men was to build up muscle mass. It is possible to state conclusions that prevalence of using dietary supplement among students is similar to values reported previously in the literature. Males were definitely more often undertaking physical activity in the gym and that could be the reason why they were definitely more often using specific dietary supplements.

The aim was to study the effect of a formative program about nutrition as well as weight management and its risks in elite gymnasts. The sample was 37 under-18 Spanish athletes from rhythmic and aesthetic gymnastics (national level). The sample was divided into a control group (n=21) and an intervention group (n=16). A quasi-experimental design with a pre-test and post-test was used. The dependent variable was the knowledge of nutrition, weight management, and its risks. The independent variable was the educational program. The program had three 30-minute sessions which combined talks, videos, and tasks to complete. Descriptive and inferential analyses were done. The educational program was ineffective with regard to increasing the gymnasts’ knowledge about nutrition, weight management, and its risks. The gymnasts’ knowledge of nutrition and weight management was high before beginning the intervention. Gymnasts and the coach expressed the need for individualized training adapted to each gymnast’s needs and for incorporating a follow-up that provides feedback that is applicable in the gymnast’s daily life.

Background: Childhood represents a risk period of susceptibility to sport-related injuries. Objectives: The aim of the study was to investigate the prevalence of sports-related injuries including orofacial traumas in children attending primary schools and participating in competitive sports, then to compare their situation with that of children engaging in sporting activities only at school and in their leisure time. The second aim of the study was concentrated on the use of sports mouthguards. Methods : Data was obtained by means of a questionnaire and statistically analysed by the basic statistic methods in Microsoft Office Excel and Pearson’s chi-square test , and a statistical significance level p < 0.05 was established. Results: 341 children (175 girls and 166 boys) completed the questionnaires and 204 (59.8%) of them were competitive athletes. 146 (42.8%) children reported sports-related injuries and 47 (13.8%) children registered trauma of the orofacial region. Only 10 (2.9%) children regularly use sports mouthguards. No statistically significant differences were detected in the occurrence of sport-related injuries including orofacial traumas between the competitive athletes and non-competitive children. Conclusion: Sport-related trauma represents a risk not only for children engaging in competitive sport activities but also for children doing sports at school and occasionally in their free time.

Opis:
The modern decathlon is a sport consisting of ten different events held over two days, played by men. Depending on the complexity of combined events, variety of events (runs, throws, jumps), the multi-stage, time-consuming and difficult training process the sport is considered as one of the most difficult. The analysis of careers of the best decathlon participants and applying advanced data-mining methods can help define the patterns occurring between each decathlon event and the final result. The research material encompasses career data of the 25 top competitors from Poland in years 1985–2015. Principal component analysis (PCA) was used in the research in order to designate new uncorrelated variables (components), representing input data across a new plane. Data analysis involved appointment of correlations between the events, determining the number of main components taken into account in further studies, analysis of the weight of each variable in formation of main components as well as visualisation and interpretation of results in the new plane described by the determined main components. Through the implementation of PCA method in the process of analysis it was possible to designate over 69% of compound data volatility with the use of the first three components. The first component, comprised of seven variables, displays the largest share in the total variability. The study of the relationship between variables in the new plane displayed strong correlations between sprint events (100 m, 110 m hurdles) and long jump and pole vault. No correlations between the 1500 m run and other events were found.
