The aim of the presented work is to prove that construction of large sports facilities in the urban space, can generate positive changes and revitalization of degraded areas. On the basis of comparative analysis of cases in which such activities took place, it can be concluded that locating these facilities in heavily degraded urban areas is one of the most eff ective methods of large-scale revitalization. This is mainly visible in post-industrial areas, which are usually well linked to canals, rivers and other waterways or reservoirs. The vast spaces around sports facilities create favorable conditions for additional recreational functions, such as parks and green areas, which in connection with water become a very attractive place for the residents of the city. Increasing interest in the area leads to new investments such as housing estates and gradual development of a multi-functional urban structure. One of the most important factors leading to this type of transformation is the modernization of the communication infrastructure which enables connection between revitalized areas and the rest of the city. A well-planned program of newly emerging sports facilities is also an extremely important factor. As research shows, large multifunctional sports and entertainment facilities, can function as a new kind of public space in the city. This leads not only to the establishment of completely new social relations, but also to the creation of jobs and the general improvement of the broadly understood image of the district.
The article presents the ideas of flexible design in the construction sector. Flexibility in the construction sector was discussed and defined between typical and flexible approaches to design. The idea applied during the economic effectiveness analysis of construction projects was introduced. The issue of flexibility was discussed based on the example of construction of a sports facility - The National Stadium in Warsaw. An effectiveness analysis was applied for variant solutions.
Theory and practice of sport psychology suggest that emotional and behavioral states of anxiety and aggression both affect athletic performance. The aim of the present study was the investigation of possible differentiation among water -polo male and female players according to their anxiety, anger and aggression levels. The sample consisted of 225 players (120 men, 105 women), between the ages of 17–39 years old. They completed the Greek versions of the: (a) CSAI -2, and (b) CAAS instruments. Results revealed differences among almost all questionnaire variables, between sport (athletic) experience’ groups. Finally, male athletes of the 2nd national division identified greater levels of anger and aggression in comparison to all other division groups. Overall, results shine some light on facets that play an important role and can affect the athletic performance of water -polo players.
Introduction: The history of using performance-enhancing substances (PES) is long and it goes back to ancient times. At present, PES are employed at all levels of sport competition, starting from Olympic level contestants to individuals recreationally involved in various sports disciplines. Purpose: The objective of the study was examining the views on doping in sports in a group of physicians, together with evaluating the frequency of their contacts with this phenomenon, in their professional activities. Methods: The investigation was carried out using a validated questionnaire developed by the authors. Questionnaire included 34 questions divided into 6 sections. In total, 257 individuals participated in the study. The percentage of answers was 75.81%. Results: Among the responders, 96.50% believed that using PES by sports competitors represented unethical behavior. 42% participants declared that they met doping problem during their professional career. Almost one-third of the physicians (28.79%) declared that during their work, they consulted patient suffering from adverse side eff ects resulting from using PES. Conclusions: In Poland, physicians regard using PES as unethical behavior. They believe that a health care system professional should participate in counteracting doping in sports. Physicians — regardless of their specialty — are also exposed to PES-related problems in their professional work. In view of the above facts and the consistently increasing popularity of PES, extending the knowledge in this field among physicians seems to be of importance to allow for their offering better medical services to their patients.
