Vitamin D i ozljede kod plesaÄa: sustavni pregled
Vitamin D is involved in many different functions in the human body. Despite the
well-known benefits of vitamin D and increasing trends of testing and supplementation, there is still a
high prevalence of vitamin D deficiency worldwide, present in the general but also in the highly-active
population such as athletes and dancers. Dancers are at a higher risk of vitamin D deficiency due to
their long working hours spent indoors, without exposure to sunlight. The high level of workload and
physical demands also put dancers at a high risk of injuries. The aim of this review was to systematically
analyze the existing evidence on the association of vitamin D (serum level and supplementation)
and injuries in dancers. Medline, Scopus, SportDiscus and Web of Science were searched to identify
the available peer-reviewed articles. Five articles met the inclusion criteria (two interventional and
three observational studies), three of which additionally investigated the relationship between vitamin
D and muscle function. The reported results on positive influence of vitamin D serum level or vitamin
D supplementation effect on reduced injury occurrence and enhanced muscular function in adolescent
and elite professional ballet dancers are promising but the evidence is limited due to a low number of
studies, small samples, and methodological limitations.Vitamin D je ukljuÄen u mnogo razliÄitih funkcija u ljudskome tijelu. Usprkos dobro poznatim pozitivnim uÄincima
vitamina D i rastuÄem trendu testiranja i suplementacije u svijetu se i dalje bilježi visoka uÄestalost nedostatka vitamina D
prisutna u opÄoj, ali i u vrlo aktivnoj populaciji poput sportaÅ”a i plesaÄa. PlesaÄi su u visokom riziku od nedostatka vitamina
D zbog dugotrajnih radnih sati koje provode u zatvorenom prostoru, bez izlaganja SunÄevoj svjetlosti. Visoka razina radnog
optereÄenja i fiziÄki zahtjevi plesaÄe dovode i u visok rizik od ozljeÄivanja. Cilj ovoga preglednog rada bio je sustavno
analizirati postojeÄe dokaze o povezanosti vitamina D (serumske razine i suplementacije) i ozljeda u plesaÄa. Baze podataka
Medline, Scopus, SportDiscus i Web of Science su pretražene radi identificiranja dostupnih recenziranih publikacija. Pet
Älanaka je zadovoljilo ukljuÄne kriterije (dva intervencijska i tri opservacijska istraživanja), a u tri od njih dodatno je istražen i
odnos izmeÄu vitamina D i miÅ”iÄne funkcije. Prikazani rezultati o pozitivnom utjecaju serumske razine vitamina D ili uÄinku
suplementacije vitaminom D na smanjenu pojavnost ozljeda i poboljÅ”anu miÅ”iÄnu funkciju u adolescentnih i vrhunskih profesionalnih
plesaÄa baleta su obeÄavajuÄi, no dokazi su ograniÄeni zbog malog broja istraživanja, malih uzoraka ispitanika i
metodoloÅ”kih ograniÄenja
Upotreba i prednosti proÅ”irene stvarnosti u meÄupredmetnom pristupu
No matter what subject is taught, making meaningful connections with the real world is always the ultimate goal. This paper provides an overview of the cross-curricular approach and available augmented reality history apps and the potential for utilising them in history classes. Also, it shows how a variety of theoretical approaches to learning and teaching with immersive technologies have been synthesised to create powerful learning scenarios that integrate History, foreign language learning, social studies, and science - math. This didactic approach with interdisciplinary connecting gives an overview on how to achieve higher quality educational goals and provide students with a different experience. Studentsā experiences and reactions to this cross-curricular approach to learning were investigated. The aim is to assess the benefits of the cross-curricular approach using augmented reality while also recording the learning and behavioural outcomes that result from its implementation.Bez obzira na temu koja se pouÄava, stvaranje smislenih veza sa stvarnim svijetom uvijek je krajnji cilj. Ovaj rad daje pregled meÄupredmetnog pristupa i dostupnih aplikacija proÅ”irene stvarnosti za uÄenje povijesti te potencijala za njihovo koriÅ”tenje u nastavi povijesti. TakoÄer pokazuje kako su razliÄiti teorijski pristupi uÄenju i pouÄavanju s imerzivnim/virtualnim tehnologijama sintetizirani kako bi se stvorili snažni scenariji uÄenja koji integriraju povijest, uÄenje stranih jezika, druÅ”tvene znanosti i prirodoslovlje - matematiku. Ovaj interdisciplinarni didaktiÄki pristup ukazuje na moguÄnosti postizanja kvalitetnijih obrazovnih ciljeva i pružanja drugaÄijeg iskustva uÄenicima. Istražena su iskustva i reakcije uÄenika na ovaj meÄupredmetni pristup uÄenju. Cilj je procijeniti prednosti meÄupredmetnog pristupa koristeÄi proÅ”irenu stvarnost, istodobno bilježeÄi ishode uÄenja i ponaÅ”anja koji proizlaze iz njegove primjene
THE MOST FREQUENT INJURIES IN GOLF
Glavni cilj ovog rada je opisati neke od najuÄestalijih
ozljeda u golfu, sportu sa izrazito velikim brojem igraÄa u
svijetu i brzim rastom popularnosti. Golf je u zamahu
razvoja u naŔoj zemlji te kao sport koji jedan od važnih
elemenata planiranog daljnjeg turistiÄkog razvoja u naÅ”oj
zemlji. Opisuju ga kontinuirana dugotrajna optereÄenja
niskog intenziteta, a ne svrstava u skupinu sportova u
kojemu su ozljede Äeste te je sport bez tjelesnog kontakta
sa suigraÄima. Problem ozljeda prisutan je u amaterskom i
profesionalnom golfu. Golf udarac kompleksan
koordinirani pokret koji koristi muskulaturu gotovo
cijelog tijela a karakteriziraju ga rotacije u gotovo svim
osima. Faktori koji mogu utjecati na pojavu ozljede su
ponavljajuÄi pokreti i/ili velika sila udarca, nepravilna
tehnika tijekom jedne od faza izvoĆ°enja udarca, te
promjena opreme/palica koje nisu prilagoĆ°ene razini
kvalitete golfera, tehnici izvedbe udaraca, fiziÄkoj
pripremljenosti, dobi te spolu. Ozljeda donjeg dijela leĆ°a,
križa, najuÄestalija je ozljeda u golfu, preciznije, ruptura
miÅ”iÄa leĆ°a i sindromi prenaprezanja ili upale miÅ”iÄnih
hvatiŔta. Ozljeda lakta i podlaktice su na drugom mjestu
po uÄestalosti ozljeda u amaterskom i profesionalnom
golfu, a slijede ih ozljede gležnja i stopala te ramena i
nadlaktice te koljena. StruÄna znanja iz kineziologije u
trenažnom procesu, biomehanika udarca i fiziÄka
priprema direktno utjeÄu na smanjenje optereÄenja na
lokomotorni sustav za vrijeme igre a samim time smanjuje
se uÄestalost ozljeda.The main goal of this paper is to describe some of the
most common golf injuries. Golf is a sport of high
popularity and increasing number of players in the world.
In our Croatia golf is growing dominantly as one of key
elements development of planned tourism development in
our country. The intensities of the activity is low, but the
duration is high and as there is no contact to other players,
it is not categorized as sport where injuries are frequent.
Though , several type of injuries are present in the
amateur and professional golf as well. The golf swing is a
complex coordinated movement engaging almost entire
body musculature, and is being characterized with body
rotations in all axis. The factors that may affect the
occurrence of injuries are repetitive movements and/or
large impact forces, improper technique during one of the
swing phases, equipment/golf clubs change or the clubs
that are not appropriate to the level of golfers quality,
technique, physical condition, age and gender. The lower
back injury is the most common injury in golf, more
precisely it is a rupture of the back muscles and overuse
syndromes or inflammation of muscle insertions. The
elbow and forearm injuries are in second place injuries
occurrence in amateur and professional golf, which are
followed by ankle and foot injury, shoulder, upper arm and
knee injury. The expert knowledge in field of kinesiology
and training process, swing biomechanics and physical
preparation have a direct influence the reduction of
locomotor system load during the game and thus reduces
the incidence of injurie

Commercial phenotypic tests (API 20E) in diagnosis of fish bacteria
The available data concerning rapid identification of fish bacteria via commercial phenotypic tests demonstrate that there is no agreement regarding the choice of selection of the tests. However, API 20E, an identification system for Enterobacteriaceae and other non-fastidious Gram-negative rods developed for clinical specimens, seems to be increasingly used for the identification of fish pathogens. In this work, adaptation of API 20E for fish bacterial isolates and its distinctiveness for fish bacteria was assessed. For some bacterial fish isolates, their identification must be regarded as only presumptive. Some strains are wrongly identified because they are not included in the database of API 20E system. For comparable results, API 20E has to be adapted for bacterial fish isolates, and there should be a consensus among the fish health professionals regarding the incubation temperature and the duration of the incubation time before performing readings. API 20E reactions should be compared with the diagnostic schemes based on reactions in conventional phenotypic tests. Due to their significance for fish health and impact on the aquaculture, and because of the need for their rapid identification, some important fish bacteria should be included in the API 20E system, such as Yersinia ruckeri, Edwardsiella ictaluri, Vibrio anguillarum
