The application of platinum redox electrode for potentiometric determination of salivary a-amylase (ptyalin) is described. Ptyalin, an enzyme present in human saliva, catalyses the hydrolysis of ...starch. The nonhydrolysed starch, which amount is inversely proportional to the ptyalin concentration, forms a complex with triiodide reducing accordingly initial triiodide concentration. The change of triiodide ion concentration causes the change of the triiodide/iodide redox-couple ratio, which results with the changes of the electrode potential of a redox-sensor. The changes are directly correlated with ptyalin concentration. The experimental data were compared with an appropriate theoretical model in which the sensor and analyte properties were optimized with Solver using the least-squares criterion to fit a theoretical curve to the experimental data set. The influence of physical activity on the ptyalin level in saliva was also investigated. It was found that ptyalin concentration in the rowers saliva strongly increases after their exposing to stronger physical activity (training), even by 2,6 to 7 times in comparison with ptyaline level before training. The influence of alcohol consumption to the ptyalin level in saliva has opposite effect, i.e. after alcohol consumption the ptyalin activity/concentration dramatically desreases by 9,5 - 24,9 times compared to its activity before alcohol consumption.
The primary area of interest of this paper are the characteristics of sports tourists and the motives for their arrival at The Sports and gymnastics center "ATON" Nedelišće. Let us interpret sports ...tourists as tourists who choose sports as motives for their arrival, sports and recreational facilities, preparations, and competitions. In the Municipality of Nedelišće in Meðimurje, there is one of the top sports complexes in Croatia - "SGC ATON". The word exists is one of the hypotheses that is in this paper, from the point of view of the sustainability of the sports center itself. The sports and gymnastics center "ATON" consists of a gymnasium, a multifunctional sports hall with a fixed and an auxiliary auditorium, a ballet hall, a fitness center, a wellness room, a catering part, a locker room with ancillary rooms, an office space in the podium and the hostel ATON, all of that served by 15 employees. The connection between tourism and sports is noted by many scientists, noting the unbreakable link between them from the very beginning. The connection lies in the motives of people to engage in sports and recreation during tourist trips. It is actually a person's constant desire to play, move, have fun, change the environment, and relax, while people can also eliminate the negative consequences of the modern lifestyle (stress). The sports and gymnastics center "ATON" is one of the most modern centers in the wider region and offers its customers a rich offer of sports and sports and recreational activities, while also organizing many sports competitions, such as: gymnastics at all levels (up to the European Championships), indoor soccer competitions from local to regional, local and state karate competitions, local and regional handball and volleyball tournaments. Furthermore, the center organizes cultural and artistic events and offers accommodation services, which favor domestic and foreign athletes coming to preparations, and above all, this applies to gymnasts. Sports tourists are the most frequent guests of The Sports and gymnastics center "ATON", and they come from the wider region. In this paper we will determine which areas most of them come from, and the reason for their arrival.
There are more and more participants in the orienteering movement who use new technologies' 'smartphones' during the activities. Orienteering as a sporting event increases the attendance of tourist ...destinations in Meðimurje and throughout Croatia. Geographical diversity, the configuration of the soil with different vegetation, Meðimurje offers runners participation in the orienteering movement unique and special. With the help of a topographic map and compass, runners try to find all the checkpoints in the shortest possible time. New applications on mobile phones make it easier to move and navigate in space, and it is possible to solve the given activities while moving. The past ten years have seen an increasing number of fans of the orientation movement from primary school students to late years, so we can freely say that this is an activity for all from seven to late years. Competitions are defined by the annual calendar, but one part of the respondents deals with orienteering movements from recreation and leisure in the natural environment. The increasingly advanced racing tracking technology and sports equipment used by runners enables the organizer and runners to have an interesting and exciting sports competition with themselves or in pairs and in groups. New augmented reality technologies add value when conducting competitions. The aim of this paper is to determine the attitudes and opinions of the participants in the orientation movement on the introduction of innovative multimedia content. Orienteering is practiced by almost all age groups of both sexes, so the survey was set to determine the attitudes of respondents regarding the recognisability of orienteering and whether a new innovative way would contribute to the popularization and recognition of orienteering. The paper presents a possible solution of the application and gives ideas for the further development and its application in orientation running, as well as its application in other segments of orientation movement. The attitudes of the survey participants who are familiar with the functioning of innovative multimedia content were analysed.
Orienteering is a group of sports that require navigational skills and as a sporting event increases the number of tourist destinations in Croatia. With the help of maps and a compass, the aim is ...that the runner tries to find all the checkpoints in the shortest possible time. With its geographical diversity, soil configuration and different vegetation, every competition in Croatia feels like a unique experience. Orienteering has seen increasing number of fans of different age groups, who are competing in races which are predefined in annual calendars. The global growth and development of the sports industry contributes to the overall economic development, and the increasingly advanced racing tracking technology and sports equipment used by runners enables the organizer and runners to have an interesting and exciting sports competition with themselves or in pairs and in groups. Outdoor sports are on the rise and increasingly popular in all their forms, both in the world and in Croatia. Orienteering is a sports activity that takes the whole family into nature and allows them to spend an active day or weekend in new places with different requirements and tasks, which enables them to spend a day in a healthy sustainable environment. At the same time, the same form of sporting activity is becoming more and more popular in the education of all age groups, from kindergarten to student population. New augmented reality technologies add value when conducting competitions. The aim of the work is to introduce innovative multimedia content into the increasingly popular sports activity that is accessible to the whole family and in a new and innovative way facilitate the implementation of orienteering. The paper presents a possible solution of the application and gives ideas for the further development and its application in orientation running, as well as its application in other segments of orientation movement.

Najčešća sportska aktivnost kojom se djeca bave je nogomet. Od najranije dobi djeca
vole nogama šutati loptu, ali i druge predmete poput kamenčića, žira, češera, i sl. Nogomet ima
pozitivan utjecaj ...na smanjenje masnoga tkiva, pospješuje motoričke sposobnosti: izdržljivost,
agilnost, eksplozivnu snagu nogu, brzinu, preciznost i fleksibilnost. Usporedbom nogometa s
drugim sportskim aktivnostima, primjerice trčanja, jednako je koristan za zdravlje, a usto ima
motivacijsku i socijalizacijsku komponentu koja je bitna prilikom odrastanja. Pozitivan odnos
i navike prema tjelesnom vježbanju stečeni već u toj dobi, kasnije će se produžiti tijekom
cijeloga života (McCall i Craft, 2002). Nogomet kao igra prisutna je od vrtićke dobi pa sve do
poznih godina u nekim svojim varijantama. S toga nogomet možemo uvrstiti u sportske
aktivnosti koje preventivno djeluju na organizam od najmlađe dobi i to prije svega zbog stila
života i utjecaj takvoga života na djecu od najmlađe dobi pa sve do poznih godina. "Nogomet
je učinkovita preventivna mjera širokoga raspona i lijek za bolesti koje su posljedice životnoga
stila za njegove sudionike neovisno o godinama, spolu, razini fizičke spremnosti i nogometnoga
umijeća" Peter Krustrup, profesor sporta i zdravstvenih znanosti s danskog sveučilišta u
Odensi. Činjenica da nijedan drugi sport ne plijeni toliku pažnju ljudi kao nogomet treba to
respektirati i iskoristiti u razvoju i zdravlju djece. Nogomet s toga ima važnu ulogu razvoju i
zdravlju djece, mladih ali isto tako i odraslih osoba.
Kros trčanje je disciplina trčanja srednjih i dugih pruga u prirodi, kroz šumu, polja ili pripremljenu stazu na ravnici i sl. U radu je dan pregled povijesnog razvoja kros trčanja, te su obrađene ...njegove karakteristike. Poseban naglasak stavljen je na oblike natjecanja ovakvog oblika trčanja. Prvo kros trčanje održano je u XIX. st. u Engleskoj; u početku se trčalo na znatno duže staze nego danas. Kros trčanje može biti masovnog, ekipnog i pojedinačnog karaktera. Za održavanje kros trčanja nije potrebna posebna infrastruktura; vrlo se lako organizira, što je jedan od razloga njegove popularnosti.
Povezanost turizma i sporta postoji od samog početak njihovog razvoja. Povezanost leži u motivima ljudi da se bave sportom, rekreacijom za vrijeme turističkih putovanja. Riječ je zapravo o stalnoj ...želji čovjeka za igrom, kretanjem, razonodom, promjenom, opuštanjem, kao i važnosti uklanjanja negativnih posljedica modernog načina života (stresa). Najbolji način je promjena svakodnevnog okruženja i kretanje odnosno upražnjavane kineziološke aktivnosti koja nas veseli i opušta. Uvažavajući činjenicu da su turizam i sport najmasovnije društveno ekonomske pojave kao i jedna od najznačajnijih strateških gospodarskih i razvojnih djelatnosti Hrvatske ne samo na moru nego i u Međimurskoj županiji ukazala se potreba za edukacijom stručnih kadrova za turizam i sport. Upravo je to bio razlog za osmišljavanjem, izradu i pokretanje stručnog studija Menadžment turizma i sporta u trajanju od tri godine pri Međimurskom veleučilištu u Čakovcu.
