    No full text
    Mjesečnica je tema koja obilježava svaku ženu. Nerijetko se raspravlja o problemima, bolovima i nelagodnostima s kojima se žene susreću kad nastupa menstruacija. Kako zbog intenzivnih bolova djevojke budu spriječene izvršavati obaveze i moraju se suočavati s time svaki mjesec to postaje zaista ozbiljnim problemom. Osim narušene kvalitete života, djevojkama je potrebna pomoć i razumijevanje takvih problema, te je potrebno što više istraživanja i dokaza sa znanstvene strane, za prevenciju i ublažavanje bolova. Primarni cilj ovog istraživanja bio je istražiti potencijalni odnos između razine tjelesne aktivnosti i prevalencije dismenoreje unutar demografske skupine studentica u Hrvatskoj. Istraživanje je uključilo uzorak od 348 studentica hrvatskih Sveučilišta i Veleučilišta, prosječne dobi od 22.26 godina, sa ciljem razumijevanja utjecaja tjelesne aktivnosti na menstrualno zdravlje kod mladih žena. Iako na tragu analitičkog pristupa dosadašnjih istraživanja povezanih s razinom tjelesne aktivnosti i pojavom dismenoreje, rad nije rezultirao istom statističkom snagom zaključaka. Posredno rezultati ukazuju kako i drugi čimbenici (subjektivni doživljaj boli, pušenje, alkohol, prehrambene navike, okolina...) imaju značajan utjecaj na percipirano iskustvo menstrualne boli, čineći tjelesnu aktivnost samo jednim od čimbenika.Menstruation is a topic that marks every woman’s life. Discussions often revolve around the problems, pains, and discomforts that women face during menstruation. Due to intense pain, girls are often prevented from fulfilling their obligations and have to face this every month, which becomes a serious problem. Besides the diminished quality of life, girls need help and understanding of these issues, and more research and scientific evidence are needed to prevent and alleviate pain. The primary aim of this research was to investigate the potential relationship between the level of physical activity and the prevalence of dysmenorrhea within the demographic group of female students in Croatia. The study included a sample of 348 female students from Croatian universities and colleges, with an average age of 22.26 years, to understand the impact of physical activity on menstrual health in young women. Although following the analytical approach of previous research related to the level of physical activity and the occurrence of dysmenorrhea, the study did not yield the same statistical strength of conclusions. Indirectly, the results indicate that other factors (subjective experience of pain, smoking, alcohol, dietary habits, environment...) significantly influence the perceived experience of menstrual pain, making physical activity just one of the factors

    Uvod: Ljudska koža normalno je naseljena raznim mikroorganizmima, no u određenim slučajevima oni mogu izazivati klinički manifestnu infekciju, pri čemu je – zbog svojeg patogenog potencijala – posebni interes u ovom istraživanju stavljen na bakteriju zlatni stafilokok (Staphylococcus aureus). Sportaši su populacija koja je, kao posljedica veće učestalosti ozljede kože i okolišnih uvjeta, pod povećanim rizikom od infekcije. Pandemija bolesti COVID-19 dovela je do velikih promjena u modalitetima treninga, kao i u higijensko-epidemiološkim postulatima. Glavni cilj istraživanja bio je utvrditi razliku u kliconoštvu zlatnim stafilokokom u odnosu na kontaktnost sporta i na pojavu pandemije bolesti COVID-19, kao i utvrditi postojanje razlike u pridržavanju higijensko-epidemioloških mjera prije i tijekom ove pandemije. Ciljevi i hipoteze: Glavni cilj ovog istraživanja bio je napraviti analizu stopa kolonizacije zlatnim stafilokokom kod sportaša u uvjetima prije i tijekom pandemije COVID-19 u odnosu na kontaktnost sporta kojim se bave i njihove higijensko-životne navike. Prvi podcilj bio je utvrditi postoji li korelacija kliconoštva zlatnim stafilokokom s higijenskim čimbenicima ispitivanim u anketi. Drugi podcilj bio je utvrditi eventualnu sezonsku razliku između kliconoša. H1: U kontaktnim sportovima bit će veći postotak ispitanika koloniziranih zlatnim stafilokokom. H2: Kliconoštvo zlatnim stafilokokom bit će učestalije u gornjem dišnom sustavu nego u aksilarnoj regiji. H3: Ordinalno stupnjevanje kliconoštva pozitivno će korelirati s neadekvatnim provođenjem postulata istraživanih anketom, kao i sa stupnjem kontaktnosti određenog sporta. H4: Utvrdit će se sezonska razlika te razlika između pretpandemijskog i pandemijskog razdoblja u kliconoštvu neovisno o kontaktnosti samog sporta. H5: Pridržavanje higijenskih postulata bit će izraženije u skupini ispitanika tijekom pandemije COVID-19. Materijali i metode: Provedena je presječna studija s prigodnim uzorkovanjem na 197 ispitanika – sportaša i sportašica koji prakticiraju kontaktne i nekontaktne sportove – u periodu prije i tijekom pandemije bolesti COVID-19. Ispitanici su podijeljeni u dvije glavne skupine prema dominantnoj kontaktnosti sporta koji prakticiraju, a dodatno s obzirom na razdoblje u vezi s pandemijom. Nakon potpisivanja informiranog pristanka i ispunjavanja ankete kojom su se utvrdile higijensko-epidemiološke navike ispitanika, sudionicima su učinjeni mikrobiološki brisevi predvorja nosa, ždrijela i aksile. Nakon provedene mikrobiološke analize uzoraka (koja je uključivala standardnu laboratorijsku obradu kao i napredne analitičke tehnologije poput MALDI-TOF), učinjena je statistička obrada podataka dobivenih anketom i uzorkovanjem. Provedene su metode deskriptivne i inferencijalne statistike, poput t-testa, Wilcoxonovog testa sume rangova, Leveneovog testa sume varijanci, Shapiro-Wilkovog testa odstupanja oblika opažene raspodjele od normalne, Brunner-Munzelove generalizirane verzije Wilcoxonovog testa, Fisherovog egzaktnog testa s ordinalnim skaliranjem, kao i druge statističke metode. Rezultati: Što se tiče kontaktnosti sporta, 49,75 % ispitanika prakticiralo je kontaktni, a 50,25 % nekontaktni sport. Zlatni stafilokok izoliran je kod 40,1 % svih ispitanika, a po kontaktnosti kod 58 % sportaša koji se bave kontaktnim i 42 % sportaša koji se bave nekontaktnim sportom (p = 0,071). Zlatni stafilokok je statistički značajno izoliran kod 48 % ukupnog broja muškaraca u odnosu na 27,6 % ukupnog broja žena (p = 0,0047). Ova je bakterija primarno izolirana iz predvorja nosa (64,56 % ukupnog broja kliconoša). Meticilin-rezistentni Staphylococcus aureus (MRSA) izoliran je kod 1,01 % ukupnog broja ispitanika. Osim zlatnog stafilokoka, izolirani su i drugi mikroorganizmi. Veći broj kolonija zlatnog stafilokoka porastao je iz uzoraka aksile sudionika koji su češće koristili teretanu te kod onih koji su rjeđe dezinficirali ruke, te iz uzoraka nosa ispitanika koji su češće dijelili zavojni materijal i kod onih koji su imali češća oštećenja kože. Kod ispitanika kod kojih je od mikroorganizama izoliran samo zlatni stafilokok, više je kolonizata zlatnog stafilokoka izolirano ljeti u odnosu na jesen. Također, u ovoj skupini ispitanika zamijećen je veći udio kolonizata zlatnog stafilokoka u aksili ispitanika kojima su brisevi uzeti tijekom pandemije. Rezultati istraživanja pokazali su da su ispitanici tijekom pandemije češće dezinficirali ruke i koristili zajedničku opremu, te da su rjeđe koristili teretanu. Zaključak: Istraživanjem su dokazane određene razlike u kliconoštvu zlatnim stafilokokom kod sportaša koji prakticiraju kontaktni u odnosu na one koji prakticiraju nekontaktni sport. Pronađene su i razlike u kliconoštvu u odnosu na higijensko-epidemiološke prakse, kao i na godišnja dobe te na period prije i tijekom pandemije COVID-19. Potvrđena je hipoteza da će kolonizacija zlatnim stafilokokom biti najučestalija u nosu. Dobiveni rezultati u skladu su s podacima iz svjetske literature, a poseban doprinos istraživanja je mogućnost promjena pristupa sportašima s obzirom na kontaktnost sporta temeljem dobivenih rezultata.Introduction: Human skin is normally inhabited by various microorganisms, yet in certain cases they can cause a clinically manifest infection. Due to its pathogenic potential, this thesis put the lens on Staphylococcus aureus (S. aureus). Athletes are a specific population that has an increased risk of infection due to higher frequency of skin injury and environmental conditions. The coronavirus disease 2019 (COVID-19) pandemic has led to major changes in training modalities, as well as in hygiene and epidemiological postulates. The main aim of the thesis was to determine the difference in S. aureus carriage rates in relation to contact/non-contact sports and the onset of the COVID-19 pandemic, as well as to determine the existence of significant differences in adhering to hygienic-epidemiological measures before and during the pandemic. Aims and hypotheses: The main aim of the thesis was to analyse S. aureus colonisation rates in athletes before and during the COVID-19 pandemic in relation to the level of contact pertinent for the sport they practice, as well as their hygienic lifestyle habits. There were two additional sub-aims: 1) to determine if there is a signficant correlation between S. aureus carriage and hygiene factors explored by the survey, and 2) to determine eventual seasonal difference between S. aureus carriers. H1: In contact sports, there will be a higher percentage of respondents colonized with S. aureus. H2: S. aureus infection will be more frequent in the upper respiratory system than in the axillary region. H3: Carriage rates (assessed on an ordinary scale) will positively correlate with the inadequate implementation of the hygiene postulates, as well as with the degree of contact of a particular sport. H4: There will be a significant seasonal difference and a difference between the pre-pandemic and pandemic periods in carriage rates, regardless of the level of contact of the sport itself. H5: Adherence to hygiene postulates will be higher in the group of respondents during the COVID-19 pandemic than before pandemic. Materials and methods: A cross-sectional study with convenient sampling approach was conducted on 197 respondents – athletes who practice contact and non-contact sports – in the period before and during the COVID-19 pandemic. The respondents were divided into two main groups according to the predominant type of contact of the sport they practice, and additionally with regard to the period related to the pandemic. After study participants signed the informed consent and filled out the survey which determined the hygienic-epidemiological habits, they were subjected to microbiological swabbing of the vestibule of the nose, pharynx and axilla. Upon analysing these samples (which included standard laboratory processing and advanced analytical technologies such as MALDI-TOF), statistical analysis was performed with the use of descriptive and inferential statistics methods – such as the t-test, the Wilcoxon rank sum test, the Levene test of the sum of variances, the Shapiro-Wilk test, the Brunner-Munzel generalized version of the Wilcoxon test, Fisher's exact test with ordinal scaling, as well as other statistical methods. Results: A total of 49.75% of respondents practiced contact sports, and 50.25% non-contact sports. The microorganism of interest, S. aureus, was isolated in 40.1% of all subjects – 58% of athletes who engage in contact sports and 42% of athletes who engage in non-contact sports (p = 0.071). S. aureus was isolated in 48% of men compared to 27.6% of women, which was a statistically significant difference (p = 0.0047). This bacterium was primarily isolated from the vestibule of the nose (i.e., 64.56% of the total number of carriers). Methicillin-resistant S. aureus (MRSA) was isolated in 1.01% of the total number of subjects. Apart from this bacterial agent, other microorganisms were also isolated. Furthermore, S. aureus was more frequently isolated from the axillae of participants who used the gym more often and those who disinfected their hands less often, as well as from the nasal samples of subjects who shared bandage material more often and those who presented with more frequent skin damage. In subjects who harboured only S. aureus as a potentially pathogenic microflora, higher carriage rates were seen in summer compared to autumn season. Also, in this group of subjects, a higher proportion of S. aureus carriage was observed in the axillae of subjects whose swabs were taken during the pandemic period. The results of the study showed that, during the COVID-19 pandemic, respondents disinfected their hands more often and used shared equipment, and that they used the gym less often. Conclusion: This thesis revealed certain differences in S. aureus carriage rates in athletes who practice contact sports in comparison to those who practice non-contact sports. Differences in microorganism carriage rates were also observed in relation to hygienic-epidemiological practices, seasons of the year, and the pre- or post-COVID-19 pandemic period. The hypothesis that colonization with S. aureus will be most frequently observed in the nose was confirmed

    Uvod i ciljevi S obzirom na to da postoje čvrsti dokazi o utjecaju tjelesne aktivnosti na zdravlje, intervencije za promociju tjelesne aktivnosti postale su neizostavni dio kampanja za prevenciju kroničnih bolesti i unapređenje zdravlja populacije. Za oblikovanje učinkovitih intervencija, potrebno je razumjeti čimbenike, odnosno odrednice o kojima ovisi tjelesna aktivnost pojedine populacije. Pregledom dosadašnjih istraživanja, utvrđeno je da su spoznaje o odrednicama tjelesne aktivnosti u Hrvatskoj nedostatne i zastarjele. Shodno tome, ciljevi ovog istraživanja bili su utvrditi odrednice različitih tipova tjelesne aktivnosti na reprezentativnom uzorku građana Republike Hrvatske te utvrditi relativni doprinos različitih tipova tjelesne aktivnosti subjektivno-procijenjenom zdravlju građana. Metode Uzorak u istraživanju činilo je 4 909 slučajno odabranih ispitanika (53 % žena i 47 % muškaraca) u dobi od 18 do 96 godina koji žive u privatnim kućanstvima na teritoriju Republike Hrvatske. Podaci u ovom istraživanju prikupljeni su metodom anketnog upitnika pri čemu je korištena standardizirana zdravstvena anketa koja se u okviru Europske zdravstvene ankete (European Health Interview Survey - EHIS) svakih pet godina provodi u svim državama članicama Europske unije. U ovom su radu korišteni podaci o tjelesnoj aktivnosti, socio-demografskim obilježjima, obilježjima načina života i subjektivno-procijenjenom zdravlju. Rezultati Multiplom hijerarhijskom regresijskom analizom je utvrđena statistički značajna povezanost skupa socio-demografskih varijabli (spol, dob, stupanj obrazovanja i stupanj urbanizacije - prvi skup prediktora) i varijabli načina života (konzumacija voća, konzumacija povrća, konzumacija cigareta, konzumacija alkohola i indeks tjelesne mase (ITM) - drugi skup prediktora) s hodanjem, vožnjom bicikla, rekreacijskim aerobnim tjelesnim aktivnostima i vježbanjem s opterećenjem (kriteriji). Socio-demografska obilježja, s različitim tipovima tjelesnih aktivnosti dijele od 1,6 do 5,8 % zajedničke varijance. Generalno, muškarci su aktivniji od žena, dob je negativno, a stupanj urbanizacije pozitivno povezan s tipovima tjelesne aktivnosti (p < 0,05). Stupanj obrazovanja je negativno povezan s vožnjom bicikla, a pozitivno s rekreacijskim aerobnim tjelesnim aktivnostima i vježbanjem s opterećenjem (p < 0,05). Obilježja načina života s različitim tipovima tjelesne aktivnosti dijele od 2,6 do 6,7 % zajedničke varijance. Generalno, konzumacija voća i povrća su pozitivno, a konzumacija cigareta i ITM su negativno povezani s tipovima tjelesne aktivnosti (p < 0,05). Iznimka je bila pozitivna povezanost između konzumacije cigareta i hodanja (p < 0,05). Konzumacija alkohola nije značajno povezana s tjelesnom aktivnošću. Multiplom regresijskom analizom je utvrđena statistički značajna povezanost varijabli tjelesne aktivnosti (hodanje, vožnja bicikla, rekreacijske aerobne tjelesne aktivnosti i vježbanje s opterećenjem - prediktori) sa svakom pojedinom varijablom subjektivno-procijenjenog zdravlja (generalna procjena vlastitog zdravlja, ograničenja zbog zdravstvenih tegoba, kronične bolesti ili stanja, tjelesni bolovi, mentalno zdravlje, obavljanje svakodnevnih aktivnosti bez pomoći, poteškoće u obavljanju kućanskih poslova bez pomoći - kriteriji). Varijable tjelesne aktivnosti s varijablama subjektivno-procijenjenog zdravlja dijele od 1,9 % do 9,2 % zajedničke varijance. Generalno, tipovi tjelesne aktivnosti su pozitivno povezani s generalno procijenjenim vlastitim zdravljem, a negativno sa svim ostalim varijablama subjektivno-procijenjenog zdravlja (p < 0,05) implicirajući da manja razina tjelesne aktivnosti doprinosi višem stupnju subjektivno-procijenjenih tegoba, ograničenja te kroničnih bolesti i stanja. Zaključak Prilikom oblikovanja strategija i intervencija za promociju tjelesne aktivnosti posebnu je pažnju potrebno posvetiti sljedećim populacijskim skupinama: žene, osobe starije životne dobi, osobe koje žive u rjeđe naseljenim područjima, osobe s nižom razinom formalnog obrazovanja, pušači i osobe s visokim indeksom tjelesne mase. Analiza povezanosti različitih tipova tjelesne aktivnosti i pojedinih aspekata subjektivno-procijenjenog zdravlja omogućuje oblikovanje specifičnih preporuka i intervencija za unapređenje različitih aspekata zdravlja odraslih osoba u RH. Konačno, rezultati ovog rada mogu biti korisni dionicima u području javnog zdravstva prilikom oblikovanja ciljanih strategija i intervencija usmjerenih na promociju tjelesne aktivnosti i poboljšanje zdravlja populacije u Hrvatskoj.Introduction and objectives Given the strong evidence linking the physical activity to better health, physical activity interventions have become an integral part of campaigns aimed at preventing chronic diseases and improving population health. To create effective interventions, it is necessary to understand the factors or correlates related to the physical activity of specific populations. However, existing research on this topic in Croatia is lacking and outdated. Therefore, the objectives of this study were to identify the correlates of various types of physical activity in a representative sample of Croatian citizens and to determine the relative contribution of different types of physical activity to the self-perceived health of the population. Methods The study sample comprised 4,909 randomly selected participants (53% women and 47% men) aged 18 to 96 years, residing in private households within the territory of the Republic of Croatia. To gather data, we used a standardized health survey utilized within the European Health Interview Survey (EHIS) which is conducted every five years across all European Union member states. The data utilized in this study encompassed information on physical activity, socio-demographic characteristics, lifestyle characteristics, and self-perceived health. Results Through multiple hierarchical regression analysis, a statistically significant association were determined between a set of socio-demographic variables (gender, age, level of education, and degree of urbanization - the first set of independent variables) and lifestyle variables (fruit consumption, vegetable consumption, cigarette consumption, alcohol consumption, and body mass index (BMI) - the second set of independent variables) with walking, cycling, recreational aerobic physical activities, and muscle strengthening activities (dependent variables). Socio-demographic characteristics, in combination with different types of physical activities, shared 1.6% to 5.8% of the common variance. Generally, men tended to be more active than women, age was negatively associated, while older age and urban living were linked to higher levels of physical activity (p < 0.05). The level of education was negatively associated with cycling and positively associated with recreational aerobic physical activities and muscle strengthening activities (p < 0.05). Lifestyle characteristics shared 2.6% to 6.7% of common variance with different types of physical activities. Generally, fruit and vegetable consumption were positively associated, while cigarette consumption and body mass index (BMI) were negatively associated with different types of physical activities (p < 0.05). An exception was the positive association between cigarette consumption and walking (p < 0.05). Alcohol consumption was not significantly associated with physical activity. Multiple regression analysis revealed a statistically significant association between physical activity variables (walking, cycling, recreational aerobic activities, and muscle strengthening activities – independent variables) and each individual variable of self-perceived health (general self-assessment of health, limitations due to health problems, chronic diseases or conditions, physical pain, mental health, performing daily activities without assistance, difficulties in performing household chores without assistance – dependent variables). Physical activity variables shared 1.9% to 9.2% of common variance with self-perceived health variables. In general, types of physical activities are positively associated with overall health perception and negatively associated with all other variables of self-perceived health (p < 0.05), indicating that a lower level of physical activity contributes to a higher degree of subjectively perceived issues, limitations, and chronic diseases or conditions. Conclusion Our findings emphasize the need for targeted interventions, particularly for certain population groups. These include women, older individuals, residents of rural areas, people with lower educational levels, smokers, and those with a high body mass index. Tailoring interventions to address the specific needs of these groups can help encourage greater participation in physical activity. The analysis of the association between different types of physical activity and specific aspects of self-perceived health enables the formulation of specific recommendations and interventions to enhance various health aspects of Croatian adults. Overall, our findings provide valuable insights for stakeholders in the field of public health including policymakers, public health professionals, and intervention designers to develop targeted strategies and programs aimed at promoting physical activity and improving population health in Croatia

    Sastavni dio policijskog posla čini nošenje teške policijske opreme koja dovodi do biomehaničkih promjena u hodu, utječe na učinkovitost i sigurnost kretanja, a time i na povećan rizik od ozlijede policijskih službenika. Glavni cilj ovog diplomskog rada bio je ispitati specifičnosti i biomehaničke promjene obrasca hoda određenih parametara pod utjecajem opterećenja nošenjem različite razine opreme policijskih službenika Jedinice specijalne i interventne policije. U istraživanju su sudjelovali službenici Interventne jedinice policije Policijske uprave zagrebačke, muškog spola koji prije i za vrijeme testiranja nisu smjeli imati nikakve akutne, kronične bolesti ili ozljede koje bi ih spriječile u provedbi istraživanja. Za izračun prostorno-vremenskih parametara analize hoda, sila reakcija podloge te plantarnog pritiska koristila se standardizirana metoda procjene plantarnog pritiska uz pomoć pedobarografske platforme (model Zebris, Njemačka). Ovaj diplomski rad pokušao je odgovoriti na pitanje na koji način nošenje policijske opreme različite težine može utjecati na kinetičke (sile i pritiske), prostorno-vremenske parametre hoda te statičke parametre u stajanju. Kako bi se pridonijelo smanjenju učestalosti ozljeda, zdravlju mišićno-koštanog sustava te uspostavio ergonomičnije pozicioniranje različitih komponenti opreme na tijelu policijskih službenika, potrebno je informirati rukovoditelje i voditelje Jedinice specijalne i interventne policije o dobivenim rezultatima.Carrying heavy police equipment is an integral part of police work, which leads to biomechanical changes in gait, affects the efficiency and increases the risk of injury to police officers. The main goal of this master's thesis was to determine the specifics and biomechanical changes in the gait pattern of certain parameters under the influence of the load by wearing different levels of equipment of police officers of the Police Special and Intervention Unit. Male officers of the Police Intervention Unit of the Zagreb Police Department participated in the research, which before and during the testing were not allowed to have any acute, chronic diseases or injuries that would prevent them from performing the test. A standardized method of estimating plantar pressure using a pedobarographic platform (Zebris model, Germany) was used to calculate static parameters measured in a standing position and to calculate the spatiotemporal parameters of gait analysis. To contribute to lower incidence of injuries, the health of the musculoskeletal system and to establish a more ergonomic positioning of various equipment components on the body of police officers, it is important to inform the managers and leaders of the Special and Intervention Police Unit about the results obtained

    Košarka spada u grupaciju kompleksnih sportova te ju karakterizira izrazita dinamičnost koja proizlazi iz kondicijsko motoričke pripremljenosti igrača, ali i njihove tehničko taktičke obučenosti. Važnost dijagnostike motoričkog prostora predstavlja temelj u izradi plana i programa treninga u košarci. Agilnost u današnje vrijeme očituje se u mnogim situacijama tijekom košarkaške igre, a temelji se na brzoj izvedbi promjene smjera kretanja. Procjena agilnosti se bazira na izvedbi određenog motoričkog znanja koji se pojavljuje u određenom testu, ali izuzetno je bitno voditi brigu o tome da li je motoričko znanje izvedeno na zadovoljavajući način kako ne bi došlo do pogrešne interpretacije rezultata. Upravo iz navedenih razloga važno je analizirati testove za procjenu agilnosti, ali i prikazati mogućnosti istih uz primjenu određenih modernih tehnologija koje u konačnici djelomično omogućavaju izbjegavanje navedenih pogrešaka u procjeni. Također, važno je sistematizirati novija dosadašnja istraživanja u području dijagnostike agilnosti kod košarkaša kako bi trenerima omogućila lakše definiranje modelnih vrijednosti u navedenom motoričkom prostoru.Basketball is classified among complex sports, characterized by pronounced dynamism arising from the physical and motor readiness of players, as well as their technical and tactical skills. The importance of diagnosing the motor space forms the foundation in developing training plans and programs in basketball. Agility manifests itself in many situations during basketball games today, relying on rapid execution of changes in movement direction. Assessing agility is based on the performance of specific motor skills appearing in a particular test, but it is crucial to ensure that motor skills are executed satisfactorily to avoid misinterpretation of results. Therefore, it is important to analyze agility assessment tests and demonstrate their possibilities using certain modern technologies that ultimately partially prevent the aforementioned errors in assessment. Additionally, it is crucial to systematize recent research in the field of agility diagnostics in basketball players to facilitate coaches in defining model values in this motor space

    Ovim diplomskim radom se želi prikazati da velika sportska događanja poput nogometnog svjetskog prvenstva 2006. u Njemačkoj jačaju kulturne vrijednosti, afirmaciju identiteta i nacionalnog ponosa zemlje domaćina. Utvrditi i prikazati strategije putem dobro orkestriranih nacionalnih i internacionalnih kampanja, civilnog društva, kulturoloških organizacija s jednim ciljem; postići nacionalni prestiž i poboljšati „nacionalnu sliku“ Njemačke. Cilj rada je prikazati kako kolektivna emocionalna svijest putem rituala( medija) utječe na nacionalnu identifikaciju zemlje domaćina tj. Njemačke. Prikazati kako je slogan svjetskog nogometnog prvenstva u Njemačkoj „Time to make friends“ vodio prema „prijateljskom nacionalizmu“ Njemačke prema ostalim zemljama svijeta. Na koji način nogometno svjetsko prvenstvo 2006. godine odražava nacionalnu sliku zemlje domaćina tj. Njemačke prema drugim zemljama svijeta; nacionalni prestiž. Ispitati koji politički ciljevi se ostvaruju putem svjetskog nogometnog prvenstva. Utvrditi da li nakon 2. svjetskog rata nogometno svjetsko prvenstvo pozitivno utječe na nacionalnu sliku Njemačke, jače izražavanje patriotizma. Utvrditi kako je mentalitet njemačke nogometne reprezentacije povezan sa mentalitetom građana Njemačke. Prikazati kako je politika njemačke vlade bila orijentirana prema „novom“ patriotizmu o ujedinjenoj Njemačkoj, te kako je prvenstvo pridonijelo jačanju ekonomske i političke pozicije Njemačke u zapadnoj Europi.This thesis aims to demonstrate that major sporting events such as the 2006 World Cup in Germany strengthen cultural values, the affirmation of the identity and national pride of the host country. Determine and present strategies through well-orchestrated national and international campaigns, civil society, cultural organizations with one goal; achieve national prestige and improve the "national image" of Germany. The aim of the paper is to show how collective emotional awareness through rituals (media) affects the national identification of the host country, i.e. Germany. To show how the slogan of the world football championship in Germany "Time to make friends" led to the "friendly nationalism" of Germany towards other countries of the world.

    Ispitivanje je provedeno na uzorku od 40 učenika četvrtih razreda srednje škole Gimnazije Karlovac. Učenici su bili podijeljenih u kontrolnu skupinu od 20 učenika i eksperimentalnu skupinu od 20 učenika. Eksperimentalna skupina koristila je obrnuti model učionice s video materijalima pripremljenima od strane istraživača, dok kontrolna skupina nije koristila dodatne materijale. Kroz razdoblje od četiri tjedna, učenici su radili na projektu koreografije plesa koristeći video materijale (eksperimentalna skupina) ili bez njih (kontrolna skupina). Motivacija učenika procijenjena je pomoću upitnika očekivanih vrijednosti (EVQ) prije i nakon eksperimenta. Upitnik se sastojao od 11 pitanja, mjereći četiri dimenzije motivacije: vrijednost postignuća (AV), intrinzična vrijednost (IV), utilitarna vrijednost (UV) i očekivana uvjerenja (EB). Učenici koji su koristili obrnuti model učionice pokazali su veću angažiranost, bolje razumijevanje materijala i veću spremnost za samostalno učenje. Obrnuta učionica pokazala se učinkovitom metodom za povećanje motivacije učenika u nastavi TZK. Istraživanje sugerira da bi obrnuti model učionice mogao biti koristan pedagoški pristup u različitim obrazovnim kontekstima, posebno u predmetima koji zahtijevaju praktične i interaktivne aktivnosti. Rezultati istraživanja nisu statistički značajni te se ne mogu donositi konkretni zaključci.The study was conducted on a sample of 40 fourth-year high school students from Karlovac Gymnasium, divided into a control group of 20 students and an experimental group of 20 students. The experimental group used a flipped classroom model with video materials prepared by the researcher, while the control group did not use additional materials. Over a four-week period, students worked on a dance choreography project using video materials (experimental group) or without them (control group). Student motivation was assessed using the Expected Value Questionnaire (EVQ) before and after the experiment. The questionnaire consisted of 11 questions, measuring four dimensions of motivation: achievement value (AV), intrinsic value (IV), utilitarian value (UV) and expected beliefs (EB). Students who used the flipped classroom model showed greater engagement, better understanding of the material, and a higher willingness to learn independently. The flipped classroom proved to be an effective method for increasing motivation in physical education classes. The research suggests that the flipped classroom model could be a useful pedagogical approach in various educational contexts, especially in subjects that require practical and interactive activities. The results of the study are not statistically significant and therefore no concrete conclusions can be drawn

    Primarni cilj istraživanja bio je utvrditi valjanost i pouzdanost subjektivne procjene opterećenja treninga (SPOto), kao mjere trenažnog opterećenja u odnosu na Banisterov trenažni impuls (Banisterov TRIMP) i Edwardsovo trenažno opterećenje (Edwardsovo TO), kroz provedbu tri treninga iste vrste u taekwondo disciplini forma. Istraživanje je provedeno na 11 natjecatelja u formama, koji su najprije proveli progresivni test opterećenja (Beep test) zbog utvrđivanja maksimalne srčane frekvencije. Potom, kroz idućih deset dana provedena su tri treninga iste vrste, točnije situacijski trening forma. Tijekom svih treninga, ispitanicima se pratila frekvencija srca. Po završetku svakog treninga, ispitanici su imali trideset minuta za odmor i hlađenje te su nakon toga prikupljane ocjene SPOt-a za svakog ispitanika. Pearsonov (r) te Spearmanov (rs) koeficijent korelacije korišteni su za prikazivanje povezanosti između varijabli trenažnog opterećenja. Dobiveni rezultati upućuju na statički značajnu korelaciju između SPOto i Banisterovog TRIMP-a u prvom treningu (r=0,78), a između SPOto i Edwardsovog TO nema statistički značajne povezanosti (r=0,15). U drugom treningu ne postoji statistički značajna korelacija između SPOto i Banisterovog TRIMP-a (r=0,41) te između SPOto i Edwardsovog TO (r=0,46). Dok, u trećem treningu postoji statistički značajna korelacija između SPOto i Banisterovog TRIMP-a (r=0,64) te između SPOto i Edwardsovog TO (r=0,70). ANOVA za ponovljena mjerenja korištena je za utvrđivanje pouzdanosti metode subjektivne procjene opterećenja treninga. Dobiveni rezultati ukazuju kako je SPOto pouzdana metoda jer ne postoji statistički značajna razlika između tri provedena treninga (p=0,28). Na temelju analiziranih rezultata, preporuča se korištenje SPOto kao pouzdane i valjane metode za određivanje i praćenje trenažnog opterećenja u treningu forma.The primary goal of the research was to determine the validity and reliability of the subjective assessment of training load (sRPE) as a measure of training load in comparison to Banister's training impulse (Banister's TRIMP) and Edwards' training load (Edwards' TL) through the implementation of three identical training sessions in the taekwondo discipline of forms. The study was conducted on 11 forms competitors who first performed a progressive load test (Beep test) to determine their maximum heart rate. Then, over the next ten days, three identical training sessions, specifically situational form training, were conducted. During all training sessions, the participants' heart rates were monitored. After each training session, the participants had thirty minutes for rest and cooling down, after which sRPE ratings were collected for each participant. Pearson's (r) and Spearman's (rs) correlation coefficients were used to show the relationship between the training load variables. The results indicate a statistically significant correlation between sRPE and Banister's TRIMP in the first training session (r=0.78), while there is no statistically significant correlation between sRPE and Edwards' TL (r=0.15). In the second training session, there is no statistically significant correlation between sRPE and Banister's TRIMP (r=0.41) or between sRPE and Edwards' TL (r=0.46). However, in the third training session, there is a statistically significant correlation between sRPE and Banister's TRIMP (r=0.64) and between sRPE and Edwards' TL (r=0.70). Repeated measures ANOVA was used to determine the reliability of the subjective assessment method of training load. The results indicate that sRPE is a reliable method because there is no statistically significant difference between the three training sessions (p=0.28). Based on the analyzed results, the use of sRPE is recommended as a reliable and valid method for determining and monitoring training load in form training

    Ovaj diplomski rad opisuje sportove skijanje na vodi i wakeboard - njihovu povijest i razvoj, kineziološku analizu, od metodike poučavanja početnika do zahtjeva samih sportova. Na početku rad upoznaje čitatelja sa općim informacijama iz povijesti, od ljudi koji su sudjelovali u njegovom stvaranju i organizaciji pa sve do razvoja sporta kakvog poznajemo danas. Temeljni cilj ovog rada je prikazati korist ovih sportova, te mogućnost primjene u ljetnim mjesecima kao zamjena za alpsko skijanje i druge zimske sportove. Naime, ova dva načina skijanja vezana su uz turističke centre u planinama, te uz more i jezera, a međusobno se mogu nadopunjavati. Kako se alpsko skijanje provodi u pravilu oko četiri mjeseca godišnje, od početka prosinca do početka travnja, potrebno je naći što više kvalitetnih zamjena ove aktivnosti. Rad će nas upoznati sa zakonitostima, zahtjevima i načinima poučavanja ovih sportova, te njihove povezanosti sa ekologijom, financijama i drugim mogućnostima. Također će nas poučiti o opremi potrebnoj za provođenje aktivnosti i mjerama sigurnosti koje je potrebno provoditi.This theoretical paper describes the sports of waterskiing and wakeboarding - their history and development, kinesiologic alanalysis, from the methodology of teaching beginners to the requirements of the sports themselves. At the beginning, the work introduces the reader to general history information, from the people who participated in it's creation and organization to the development of the sport as we know it today. The main goal of this work is to show the recreational benefits of the sports, and the possibility of using the summer months as a substitute for alpine skiing and other winter sports. Namely, these two ways of skiing are connected to tourist centers in the mountains, and to the sea and lakes, and they can complement each other. As alpine skiing is usually carried out for about four months a year, from the beginning of December to the beginning of April, it is necessary to find as many quality substitutes for this activity as possible. The work will introduce us to the laws, requirements and methods of teaching these sports, as well as their connection with ecology, finance and other possibilities. They will also teach us about the equipment needed to carry out the activity and the safety measures that need to be implemented
