This study is established on the aim to analyse a game and determine differences in a shot efficacy in an offence the woman’s handball national teams at the Olympic games in Tokyo 2021. Four national teams were analysed: France, Russia, Norway and Sweden. To analyse a game in the offence, 12 variables were used: total number of shots (sut_uk), efficient number of shots (sut_usp), total number of shots from 6 meters (sut_m6_uk), efficient number of shots from 6 meters (sut_m6_us), total number of shots from wings (sut_kril_uk), the efficient number of shots from wings (sut_kr_us), total number of shots from 9 meters (sut_m9_uk), efficient number of shots from 9 meters (sut_m9_us), total number of shots from 7 meters (sut_m7_uk), efficient number of shots from 7 meters (sut_m7_us), total number of fast centres (brzc_uk) and total number of efficient fast centres (sut_brzc_us). All national teams had the approximal number of efficient shots on a goal. The highest number of efficient shots from 6 m had the French and Norwegian national teams. From the wing position, the highest number of efficient shots had the Norwegian national team, while the lowest number of efficient goals from the wing position had the Russian national team. The Norwegian and French national teams were approximately efficient in the shot’s realisation from 9 m. In a realisation of the fast centre, the Russian national team stands out with the highest number and the French national team had the lowest number of efficient shots.

The World Health Organization (WHO) released guidelines for physical activity, sedentary behav-iour, and sleep for children under 5 years of age in 2019. In response to these guidelines, this study aimed to determine the proportion of preschool children (ages 3-5 years) who met the WHO guidelines. The time spent in physical activity, sedentary behaviour and sleep were objectively measured using accelerometer (ActiGraph wGT3x-BT). Screen time and sleep quality were assessed via parent questionnaire. Focus groups were con-1 ducted with parents and childcare staff to determine the feasibility of the protocol. The results showed that only 23% of the children met all three guidelines, and compliance rates varied for each guideline. The physical activity time guideline was met by 64% of children, the sleep duration guideline was met by 74% of children, and the screen time guideline was met by 53% of children. Only a low proportion of children met the WHO guidelines. The methods and devices used in this pilot study proved to be feasible and this has paved the way to conduct the main SUNRISE study in Bosnia and Herzegovina.

This study has been undertaken to perform the game analysis, to determine an efficacy difference in an offence of four first placed woman handball national teams at the Olympic games in Tokyo. One of the problems, which undergoes scientific research, is competition between teams and an efficacy in the mentioned sport. The performance of any technical element in the handball is impossible to perform without the adequate motoric ability, as well as the quality of the motoric ability is impossible to perform without the rational technique. In this study, based information were obtained from first THIRD handball national teams of France, Russia and Norway during eight matches at the Olympic games in Tokyo. The total of 12 offence’s variables were obtained from 8 matches of woman’s handball national teams and analysed: total number of shots (sut_uk), precise - efficient number of shots (sut_pre), total number of shots from 6 meters (sut_m6_uk), precise - efficient number of shots from 6 meters (sut_m6_pre), total number of shots from wings (sut_kril_uk), precise - efficient number of shots from wings (sut_kr_pre), total number of shots from 9 meters (sut_m9_uk), precise - efficient number of shots from 9 meters (sut_m9_pre), total number of shots from 7 meters (sut_m7_uk), precise - efficient number of shots from 7 meters (sut_m7_pre), total number of fast centres (brzc_uk) and total number of precise - accomplished fast centres (sut_brzc_pre). Based on the analysis in this study, it is evident that the game of national teams was based on shots from 9 m, shots from 6 m, and on the fast performance of the fast centre. By analysed results, could be concluded, that these variables significantly determinate the game in offence on this tournament. Keywords: Women, handball, national teams, Olympic games

The research was conducted in order to determine the differences in situational-motor abilities in the defense of men's junior national teams at the 2013 World Handball Championship. Situational - motor abilities in the defense of the national team of Bosnia and Herzegovina in relation to the national teams of Croatia, France, Sweden and Spain were analyzed. The following variables were used to determine differences in defense: SKODEKUK / PR - total - average number of jumps in defense of the whole team, SKODUK / PR1 - total - average number of jumps in defense first player of defense, SKODUK / PR2 - total - average number of jumps in defense second defensive player, SKODUK / PR3 - total - average number of defensive jumps third defensive player, SKODUK / PR4 - total - average number of defensive jumps fourth defensive player, SKODUK / PR5 - total - average number of defensive jumps fifth defensive player and SKODUK / PR6 - total - average number of jumps in the sixth defense player. To determine the partial quantitative differences of variables, which measure the total and average number of attempts to perform an element in the area of situational - motor abilities in defense, we used the mean difference of mean (hereinafter MD), which calculated the average values of selected variables. The average values of variables for the assessment of situational - motor abilities in defense were also calculated. The variable SKODUK / PR4 - total - average number of jumps in the defense of the fourth player shows a statistically significant negative difference in the jumps in the defense of the fourth player between the fourth player in the defense of Bosnia and Herzegovina and the fourth player in the defense of Croatia and Sweden. In the variable SKODUK / PR6 - total - average number of jumps in the defense of the sixth defense player, a statistically significant negative difference can be seen between the sixth player in the defense of the national team of Bosnia and Herzegovina and the sixth player in the defense of Sweden.

Za ostvarenje vrhunskih rezultata potreban je: daroviti sportas, kvalitetan trenažni proces, strucni trenerski tim ali i suvremena materijalna, organizacijska i znanstvena potpora. Analize pokazuju da se najvisa sportska postignuca ne mogu ostvariti ako se ne primjene rezultati znanstvenih istraživanja a svjedoci smo da se u posljednjih dvadesetak godina, vezano uz rukometnu tematiku, broj istraživanja i objavljenih radova znatno povecao. Suvremeni pristup bazicnim i specificnim antropoloskim obilježjima rukometasa te specificnim zahtjevima i karakteristikama rukometne igre traži znanstveno utemeljene analize i spoznaje do kojih se može doci jedino na temelju znanstveno – istraživackih projekata. Tako je postavljena i tema ovog rada sa ciljem analize i obrade morfoloskih obilježja. Morfoloske osobine određuju tjelesnu građu covjeka i izuzetno su važne za uspjesnost u kinezioloskim aktivnostima. Jasno je da razlicitosti (specificnosti) u kinezioloskim aktivnostima, zahtijevaju i specificnu tjelesnu građu primjerenu upravo toj aktivnosti (kosarka – visinu, bacanje kugle – misicnu masu, gimnastika – niži rast, itd.). Uvažavajuci strukturna obilježja i zahtjevnost rukometne igre, a u njoj posebno specificnosti mjesta ili igracke pozicije, morfoloska obilježja predstavljaju jedan od osnovnih preduvjeta uspjesnosti u rukometu. Rezultati dobiveni ovim radom, potencijalno bi trebali prosiriti teorijske spoznaje, a morfoloske dimenzije vrhunskih rukometasica mogu služiti kao modelne vrijednosti, sto može imati znacajni utjecaj na originalnost i univerzalnost znanstvenog temeljenja selekcije, metodologije i programiranja
