The approaches, methods and procedures in the preservation and conservation of paintings on wooden and textile panels in the period from 1948 until 2008.

Ovaj će diplomski rad pokušati objasniti pristupe, metode i postupke zaštite slika na drvenim i tekstilnim nosiocima u razdoblju od 1948. godine do drugog desetljeća 21. stoljeća. Temeljem proučavanja arhivske dokumentacije trideset pet štafelajnih slika u vlasništvu Strossmayerove galerije, koncizno je prezentiran razvoj konzervatorsko-restauratorske prakse u Hrvatskoj s naglaskom na pokretnu kulturnu baštinu. Dok će u prvom dijelu rada biti objašnjeno formiranje umjetničke zbirke i razrada koncepta stalnog postava Strossmayerove galerije, drugi dio rada bit će posvećen praksi zaštite slika u Hrvatskoj kao recepciji i refleksiji teorije konzervacije u Europi. Promjene u pristupima, metodama i postupcima zaštite te upotrebi restauratorskog materijala, kronološki će biti predstavljene i objašnjene konkretnim primjerima intervencija na slikama iz Stare galerije.This thesis attempts to explain the approaches, methods and procedures in the preservation and conservation of paintings on wooden and textile panels in the period from 1948 until the second decade of the 21st century. The development of the conservation and restauration praxis in Croatia with an accent on movable cultural heritage is concisely presented through the research of the archival documentation of thirty-five easel paintings owned by the Strossmayer Gallery of Old Masters in Zagreb. While the first part of the thesis explains the formation of the art collection and the concept elaboration of the collection in the permanent exhibition of the Strossmayer Gallery, the second part of the thesis focuses on the praxis of the preservation of paintings in Croatia as a response to and a reflection of the European theory of conservation. The changes in the approaches, methods and procedures of preservation and the usage of restorative materials will be presented and explained through concrete examples of interventions on the paintings from the Strossmayer Gallery of Old Masters

THE IMPORTANCE OF CORNERS IN THE TACTICAL PREPARATION OF PROFESSIONAL FOOTBALLERS

Corners are a segment of the game from which goals are not often scored, but they may be a decisive factor in the outcome of the match between the two teams. The aim of this research is to determine the characteristics of performing a corner kick and to examine whether there are differences between different competitions of professional football players. The sample of respondents represents the matches of the International Champions Cup in the 2018 season and the matches of the Spanish league (La Liga) in the 2017/2018 season. A total of 23 matches (13 matches of the International Champions Cup and 10 matches of the Spanish league) were analyzed. To describe the tactics of corner kicks, variables were observed that indicate the way the kicks are performed from the corner. The methodology of observing several teams, monitoring all matches and monitoring both teams in each match with the analysis of given variables was used. Corner kicks that had more than three passes, which means starting a new, organized attack, were excluded from the analysis. A total of 209 of the 253 corners were included. The results show that there is no statistically significant difference in most of the observed parameters, but in the type of defense that the teams apply, play and lateral performance, there are statistically significant differences. Zone defense (.012) is used more by teams that competed in the International Champions Cup and combined (.036) by teams in the Spanish league. There are also differences in the playoffs (.047) in favor of the International Champions Cup. Corners from the same side (.031) were used more in the International Champions Cup than in the Spanish league. These results show that the teams do not differ much in the way they set up in the defensive phase and the attack phase, but that there are certain common criteria. Article visualizations

Correlation between linear speed, change of direction speed and dribble deficit in male handball players

The aim of this study was to determine the relationship between linear sprint and change of direction (COD) speed using the novel approach of the Dribble Deficit (DD) among professional handball players. This study included 14 male professional handball players (age = 23.1 ± 3.43). Each player performed the following tests: a 10, 20 and 30 meter linear sprint; a zig-zag test; a slalom test and 4 × 5 agility test with and without a ball. A significant correlation was found between the DD at 10 m and the 10 m sprint with the ball (p < 0.05, r = 0.575). Additionally, the results showed that the values of dribble deficit during slalom test were related (p < 0.01) to the 20-m sprint with the ball (r = 0.767), the 30-m sprint with a ball (r = 0.765) and the slalom with a ball (r = 0.938). Regression analyses showed significant influence of the linear sprint at 10 m on DD (p = 0.02, R2 = 0.373), and the zig-zag test without ball on the DD (p = 0.004, R2 = 0.514). The results suggest that the linear sprint and zig-zag test used to evaluate COD movement speed are associated with and influence DD in professional handball players. Further research on DD is necessary in order to determine that DD is not influence by physical performance and how we can use it in the future to calculate the time required for dribbling

PREVALENCA DEFORMITETA STOPALA SPORTISTA SA RAZLIČITIM SPORTSKIM ISKUSTVOM

Changes and deformities to the feet are frequent among athletes. The aim of this review paper is to determine the prevalence of foot deformities among athletes with various backgrounds, as well as to determine the influence of the deformities on motor task performance. The compiled studies were published between 2002 and 2018. The following electronic databases were used for the search: PubMed, MEDLINE, Google Scholar, EBSCO. The identified studies had to satisfy the following criteria: that they included athletes and that the subject of analysis were the differences in foot deformities in relation to performing motor tasks. Research papers on this topic were reviewed and analyzed. They are clearly organized in tabular form, with a clear outline of the details of the research. The results of 16 research papers are summed up. The most prevalent deformity among athletes is flat feet (pes planus). The studies indicate the various deformities which are prevalent in particular sports, and determine the changes in the feet of the athletes, in particular for the foot which plays a decisive role in certain sports. Individuals with flat feet scored lower results compared to individuals with normal arches in terms of time and reaction speed when performing motor tasks.Promene i deformiteti stopala učestala su pojava kod sportista.

UTICAJ PARAMETRA TELESNE KOMPOZICIJE NA EKSPLOZIVNE SNAGE KOD FUDBALERKI U PERIODU ADOLESCENCIJE

The primary aim of this study was to quantify the relationship between body composition variables and explosive power performance in female adolescent football players. A secondary aim was mesure the influence of body composition on explosive power in female adolescent football players. A cross-sectional study included sixteen female adolescent football players (age: 14.5 ± 0.97 years; height: 170.06 ± 4.39 cm; weight: 61.35 ± 11.25 kg) competing as part of  the Serbia Development League. The body composition parameters were: muscle mass in percentage (MM), body fat mass in kg (BFM), body fat mass in percentage (PBF), while explosive power parameters were: CMJ Jump Height in cm (CMJHeight), CMJ Relative maximal F (CMJF), CMJ Relative maximal P (CMJP), SJ Jump Height in cm (SJHeight), SJ Relative maximal F (SJF), SJ Relative maximal P (SJP). Pearson's correlation coefficient was used to determine the correlation between all tests and a simple linear regression analysis was applied to determine the influence between body composition and explosive power performance. Significant regressions were found between MM and CMJHeight (r = 0.50, p ≤ 0.05, R2 = 0.25) and MM and SJHeight (r = 0.69, p ≤ 0.003, R2 = 0.47). Also, regression analyses were found between PBF and CMJHeight (r = 0.58, p ≤ 0.02, R2 = 0.33) and PBF and SJHeight (r = 0.72, p ≤ 0.002, R2 = 0.51). Lower values of body fat mass and body fat mass in percentage and higher values of muscle mass lead to better results in explosive power performance.Cilj ove studije bio je da se kvantifikuje odnos između varijabli telesne kompozicije i eksplozivne snage kod fudbalerki u period adolescencije. Sekundarni cilj je bio uticaj telesne kompozicije na eksplozivnu snagu kod kod fudbalerki u period adolescencije. Transverzalna studija obuhvatila je šesnaest fudbalerki (godine: 14,5 ± 0,97; visina: 170,06 ± 4,39; težina: 61,35 ± 11,25) koje su se takmičile u okviru Razvojne lige Srbije. Parametri telesne kompozicije su bili: mišićna masa u procentima (MM), masa telesne masti u kg (BFM), masa telesne masti u procentima (PBF), dok su parametar eksplozivne snage bili: CMJ Visina skoka u cm (CMJHeight), CMJ Relativni maksimalni sila (CMJF), CMJ Relativni maksimalni snaga (CMJP), SJ Visina skoka u cm (SJHeight), SJ Relativna maksimalna sila (SJF), SJ Relativna maksimalna snaga (SJP). Pirsonov koeficijent korelacije je korišćen za određivanje korelacije između svih testova, a analiza linearne regresije su primenjene da bi se utvrdio uticaj između sastava tela i performansi eksplozivne snage. Pronađene su značajne regresije između MM i CMJHeight (r = 0,50, p ≤ 0,05, R2 = 0,25) i MM i SJHeight (r = 0,69, p ≤ 0,003, R2 = 0,47). Takođe, pronađene su regresione analize između PBF i CMJHeight (r = 0,58, p ≤ 0,02, R2 = 0,33) i PBF i SJHeight (r = 0,72, p ≤ 0,002, R2 = 0,51). Manje vrednosti mase telesne masti i mase telesne masti u procentima i veće vrednosti mišićne mase utiču na bolje rezultate u performansama eksplozivne snage

EFEKTI PLIOMETRIJSKOG TRENINGA NA TELESNU KOMPOZICIJU I MOTORIČKE VEŠTINE FUDBALERKI

This paper aims to determine the impact of plyometric training programs of short duration (6 weeks) and high frequency (3 times a week) on the motor skills and body composition of female football players. The total number of participants was 24 female football players, four of whom were excluded due to absence from the final testing (mean value of height 167.53 ± 6.09; and mean value of weight 58.32 ± 8.87). The sample of variables used in the study, to which all the participants were subjected, represents the assessment of body composition, explosive power of the lower extremities, speed, agility, and endurance assessment. The results of the research showed that the six-week program of specific plyometric training for Serbian Super League football players in the basic preparatory period of the season did not affect statistically significant changes in the monitored body composition parameters. Also, the statistically significant changes did not occur in the parameters of explosive power and speed, which was expected according to the age category and level of competition of the participants, which was confirmed by previous research. The changes that occurred with high statistical significance are changes in agility tests with and without a ball as well as in the parameters of cardiorespiratory endurance.Cilj ovog rada bio je utvrditi efekte kratkotrajnog (6 nedelja) i visoko frekventnog (3 puta nedeljno) pliometrijskog treninga na motoričke sposobnosti i telesnu kompoziciju fudbalerki. Ukupan broj ispitanica u ovoj studiji bio je 24, od kojih su četiri isključene zbog izostanka sa finalnog testiranja (srednja vrednost visine 167.53 ± 6.09; srednja vrednost težine 58.32 ± 8.87). Uzorak varijabli korišćenih u istraživanju, kom si pristupile sve ispitanice, predstavlja procenu telesne građe, eksplozivne snage donjih ekstremiteta, brzine, agilnosti i izdržljivosti. Rezultati istraživanja su pokazali da šestonedeljni program specifičnog pliometrijskog treninga za fudbalerke Superlige Srbije u pripremnom periodu sezone nije uticao na statistički značajne promene praćenih parametara telesne kompozicije. Takođe, nisu se desile statistički značajne promene u parametrima eksplozivne snage i brzine, što je bilo očekivano prema starosnoj kategoriji i stepenu takmičenja ispitanica, što je potvrđeno prethodnim istraživanjem. Promene koje su se desile sa visokim statističkim značajem su promene u testovima agilnosti sa i bez lopte, kao i u parametrima kardiorespiratorne izdržljivosti

NUTRITION LEVEL AND CARDIORESPIRATORY FITNESS IN STUDENT POPULATION – A SYSTEMATIC REVIEW

The aim of this of systematic review paper was to determine whether there is a correlation between the level of nutrition and cardiorespiratory fitness in the student population. The collected papers date from the period between 2000 and 2018. The sample included both male and female students with different levels of nutrition. The analyzed studies determined the differences and changes in BMI in relation to cardiorespiratory fitness. The studies had a criterion that showed differences in nutritional level and cardiorespiratory fitness and changes in BMI and cardiorespiratory fitness. Research has shown that there are significant differences in the level of nutrition of students and their physical fitness. Students with higher BMI had poorer results on cardiorespiratory fitness tests. With the increase in BMI, the VO2max values (maximal oxygen consumption values) are reduced. Higher BMI also adversely affects other physiological parameters. Moreover, there is a high correlation between BMI levels and cardiorespiratory endurance. Students included in the systematization, with their lower body composition values, showed better results on cardiorespiratory endurance tests. Increased body mass can lead to poorer results on physical fitness tests

NIVO FIZIČKE AKTIVNOSTI STUDENATA NA UNIVERZITETU

The aim of this research was to determine the difference in the level of physical activity (PA) in students of four faculties of the University of Niš whose curricula do not include physical education (PE) classes. The PA level was evaluated using a questionnaire for the self-evaluation of PA (IPAQ-long form). The research included students of the Faculty of Philosophy, Faculty of Economics, Faculty of Law and Faculty of Electronic Engineering of the University of Niš (n=109; age: 22±0.6 months). A significant difference was determined in the level of PA among the students of the University of Niš (p=0.000). However, differences in PA during leisure time have not been determined (p=0.109). One of the reasons is the active leisure time of the student population, which through sports activities compensates for the lack of PE classes at the faculties in question.Cilj ovog istraživanja bio je da se utvrdi razlika u nivou fizičke aktivnosti (FA) studenata četiri fakulteta Univerziteta u Nišu. Predmet istraživanja je studentska populacija čiji nastavni programi ne uključuju časove fizičkog vaspitanju (FV) na Univerzitetu bez uključenih nastavnih programa nastave FV. U proceni nivoa fizičke aktivnosti  korišćen je upitnik za samovrednovanje fizičke aktivnosti (IPAQ-duža verzija). Istraživanje je obuhvatalo studente Filozofskog, Ekonomskog, Pravnog i Elektronskog fakulteta Univerziteta u Nišu (n=109; starost: 22±0.6 meseci). Utvrđena je značajna razlika u nivou FA među studentima Univerziteta u Nišu (p=0.000). Međutim, razlike u FA  tokom  slobodnog  vremena nisu utvrđene (p=0.109). Jedan od razloga je aktivno provođenje slobodnog vremena studentske populacije, koja sportskim aktivnostima nadoknađuje nedostatak FV  na fakultetima

UTICAJ SPORTA NA ZDRAVLJE I UNAPREĐENJE MENTALNE HIGIJENE STUDENTSKE POPULACIJE - SISTEMATSKO PREGLEDNO ISTRAŽIVANJE

Due to its appeal, sport has always been in the service of various social fields, both in a negative and a positive sense. A sedentary lifestyle has become noticeably dominant among students. The most frequent external barrier for taking part in physical activities among the student population is a lack of time due to their schedules or due to familial or other obligations. The aim of the research was to use a critical analysis of existing studies and a generalization of the results of all the analysed papers which studied the effectiveness of sport to show the effects of sport and physical activity (PA) on the improvement of the mental hygiene among the student population. The literature was compiled by searching the following databases:  Medline, Google Scholar, Web of Science and PubMed. The database search resulted in 198 papers of which 15 were included in the systematic review. The participants included in the systematic review were adults who attended class and were university students. An awareness of health and the positive effects of PA can be a decisive factor for motivating people to become physically more active. PA can help in the prevention and continuation of psychological wellbeing.Sport je zbog svoje atraktivnosti uvek bio u službi raznih društvenih područja kako u pozitivnom tako i u negativnom smislu. Zapaža se da je sedentarni način života postao dominantan među studentima. Najčešća spoljašnja barijera za bavljenje fizičkim aktivnostima kod studenata je nedostatak vremena zbog rasporeda predavanja i nedostatak vremena zbog porodičnih i društvenih obaveza. Cilj istraživanja je da se kritičkom analizom dosadašnjih istraživanja i generalizacijom rezultata svih analiziranih istraživanja koja su proučavala efikasnost sporta, prikažu efekti sporta i fizičke aktivnosti na unapređenje mentalne higijene studentske populacije. Literatura je sakupljena pretraživanjem sledećih naučnih baza podataka: Medline, Google Scholar, Web of Science i PubMed. Pretraživanjem naučnih baza prikupljeno je 198 radova od kojih je 15 radova uključeno u sistematski pregled. Ispitanici koji su uključeni u pregledno istraživanje bile su punoletne osobe koje su pohađale nastavu i pripadale nekom Univerzitetu. Svest o zdravlju i pozitivnim efektima fizičke aktivnosti mogu biti presudni za motivisanje ljudi i tako postati fizički aktivniji. Redovna fizička aktivnost može pomoći u prevenciji i očuvanju psihičkog zdravlja

UTICAJ FIZIČKE AKTIVNOSTI NA GOJAZNOST STARIH OSOBA - SISTEMATSKO PREGLEDNO ISTRAŽIVANJE

The aim of this review research was to determine the effects of the physical activity (PA) on obesity among the elderly. To compile existing studies on the effects of PA on obese elderly individuals, PubMed, SCIndeks, PEDro, J-GATE, DOAJ and Google Scholar electronic databases were searched. By analyzing and applying the set criteria, the final analysis included 20 studies, and the positive influence of the PA on the obesity of the elderly was confirmed. The greatest effect on the decrease in body mass was achieved by the simultaneous application of a combination of exercise programs and dietary regimen for a period of 6 months. It was concluded that combined programs of aerobics, weight training, flexibility and balance exercises for a period of at least 12 weeks lead to a mild decrease in body mass and the amount of fat mass, while maintaining and increasing lean body mass mostly in the form of muscle tissue. PA is an effective mean in reducing obesity, and thus its use among the elderly is recommended.Cilj ovog preglednog istraživanja bio je da se utvrde efekti fizičke aktivnosti (PA) na gojaznost starih osoba. Za pregled postojećih istraživanja o efektima PA na gojazne stare osobe, pretraživane su elektronske baze PubMed, SCIndeks, PEDro, J-GATE, DOAJ i Google Scholar. Analizom i primenom zadatih kriterijuma, konačna analiza obuhvatila je 20 studija i potvrđen je pozitivan uticaj PA na gojaznost starih osoba. Najveći efekat na smanjenje telesne mase postignut je istovremenom primenom kombinacije programa vežbanja i režima ishrane u trajanju od 6 meseci. Zaključeno je da kombinovani programi aerobika, treninga sa opterećenjem, vežbi fleksibilnosti i ravnoteže tokom perioda od najmanje 12 nedelja dovode do blagog smanjenja telesne mase i količine masne mase, istovremeno održavajući i povećavajući bezmasnu telesnu masu, uglavnom u formi mišićnog tkiva. PA je efikasno sredstvo za smanjenje gojaznosti, pa se stoga preporučuje njena upotreba među starim osobama
