Purpose: The main aim of the research was to analyse aggression dimensions among athletes practising martial arts and combat sports.Material and Methods: There were 219 respondents. The Buss and Perry Aggression Questionnaire (BPAQ) in the Polish adaptation by Siekierka was applied.Results: Martial arts apprentices turned out to present a statistically significantly lower level of hostility (p < 0.001) and of the general aggression index (p = 0.04) than combat sports athletes. It turned out that lower level of aggression was noted in female participants (physical aggression (p < 0.001), verbal aggression (p = 0.004), hostility (p < 0.001), and the general aggression index (p < 0.001). Analysis revealed that the training experience and the training rank did not differentiated the level of the respondents' particular aggression dimensions.Conclusions: It would be advisable to perform parallel analyses in other areas of Poland and take into account the respondents' education and place of residence.

Background In recent years, there has been a growing interest in active virtual reality games (AVRGs) that provide entertainment and encourage more physical activity (PA). Since playing AVRGs involves primarily arm movements, the intensity of this form of PA may not be sufficient for health benefits. Therefore, it is worth looking for virtual entertainment solutions that are comfortable for users and at the same time increase physical exercise. Objective The main objective of this study was to evaluate the effect of external loading of the arms in the form of handheld weights (HHWs) on exercise intensity in users playing a popular AVRG. The results obtained in the study were compared with the PA recommendations for health. The study also assessed the perceptions of the users about the attractiveness and usefulness of this type of exercise and discomfort caused by additional load on the arms. Methods The study covered 17 young adults aged 18 to 25 years playing an AVRG (Beat Saber) with no arm load and with HHWs (0.5 kg). A PlayStation 4 PRO console (Sony) with accessories including a head-mounted display and controllers was used in the study. PA intensity was evaluated using a heart rate monitor based on the percentage of maximal heart rate (% HRmax). The usability, attractiveness, and comfort perceived during exercise by users were evaluated using a survey questionnaire. Results The measurements showed that the mean % HRmax in participants playing Beat Saber without HHWs was significantly lower (P<.001; Cohen d=1.07) than that observed when playing with HHWs. It should be emphasized that with no additional load, the intensity of PA was low (mean 63.7% HRmax, SD 9.3% HRmax), while with the upper limb load, it increased to a moderate level (mean 67.1% HRmax, SD 10.3% HRmax), which is recommended for health benefits. The survey conducted in the study showed that HHWs (0.5 kg) attached to the wrists did not disturb Beat Saber players. Conclusions Since PA in most of the modern AVRGs primarily involves upper limb movements, the use of HHW seems to be a simple and effective way to increase exercise intensity, especially because, as reported by the study participants, such a procedure does not cause discomfort while using the application.

Wstęp: Dane epidemiologiczne wskazują, że blisko 80% społeczeństwa cierpi z powodu dysfunkcji kręgosłupa i tkanek okołokręgosłupowych. Dolegliwości te są zatem istotnym problemem medyczno-społeczno-ekonomicznym.Celem pracy było przedstawienie przyczyn oraz sposobów leczenia zespołów bólowych kręgosłupa na podstawie wyników najnowszych badań.Materiały i metody: Przeszukano bazy danych EBSCOhost, PubMed Medline i Scopus.Wyniki: Ból kręgosłupa spowodowany może być anomaliami wrodzonymi, zmianami zwyrodnieniowymi, stanami zapalnymi, chorobami nowotworowymi, urazami, przeciążeniem, zaburzeniami metabolicznymi, problemami psychologicznymi lub socjalnymi. W leczeniu wykorzystuje się: teorie hamowania bólu, farmakoterapię oraz fizjoterapię.Wnioski: W ostatnich latach zdecydowanie wzrasta liczba publikacji dotycząca dolegliwości bólowych kręgosłupa. Pomimo rozwoju medycyny oraz znajomości zasad ergonomii liczba osób uskarżających się na omawiane schorzenia systematycznie rośnie. Konieczne jest podjęcie szerokich działań profilaktycznych, w których istotną rolę powinno odegrać uświadomienie społeczeństwa o zagrożeniach wynikających z niedbałości o własny kręgosłup. Celem powinno być ukształtowanie prozdro­wotnych zachowań, wyrobienie poprawnych nawyków ruchowych w życiu codziennym, tj. wykonywanie systematycznych ćwiczeń i technik rozluźniających.

The aim of the study was to validate the Polish version of the Perceptions of Inclusion Questionnaire (PIQ) for the first time. The analysis included not only pupils, parents/legal guardians, and teachers but also physical education teachers, which is an innovative solution proposed by the authors. The sample consisted of 448 respondents. Confirmatory factor analysis showed that the tested model corresponding to the construct proposed by the PIQ authors did not have good fit indicators (χ2/df = 7.73; CFI = 0.855; SRMR = 0.103; RMSEA = 0.123). The three-factor structure of the questionnaire was confirmed by the eigenvalues obtained for each extracted factor based on the Kaiser criterion and the scree plot based on the Cattella criterion. All three factors showed satisfactory levels of reliability (Cronbach’s alpha > 0.7). The conditions of convergent and discriminant validity for the construct were confirmed. However, Horn’s parallel analysis showed that the optimal number of factors is 4. Therefore, the research presented here should constitute a starting point for further analyses. It is recommended that research teams should conduct further scientific exploration of the PIQ tool in four perspectives, i.e., including PE teachers’ opinions.

Although the ability to deal with stress is one of the key competences of people working in managerial positions in schools and educational establishments, principals in this area are very poorly diagnosed. The aim of this study was to consider the coping strategies used by headmasters and deputy headmasters of schools and educational establishments during the COVID-19 pandemic. For this purpose, Mini-COPE was used. The respondents (N = 159) obtained a higher mean for “active coping”, “planning”, “positive reframing”, “acceptance”, “use of instrumental support”, “venting”, and “problem-focused strategies” than the normative value. Compared to deputy headmasters, headmasters obtained higher mean results for “planning” and “religion”, and lower results for “behavioral disengagement”. Respondents with longer job seniority in a managerial position, obtained a higher mean for “use of instrumental support” and lower for “religion”. Compared to respondents employed in private schools, people in the public education sector are more likely to use “behavioral disengagement” and less their “sense of humor”. The respondents working in primary schools scored higher on average for “use of instrumental support” and “problem-focused strategies”. It would be advisable to compare the results with the teachers and the persons holding managerial positions in institutions and organizations not related to education.
