Descriptive statistics (i.e., frequency counts and percentages) and chi-square tests of association were used to analyse the data. The study observed a total of 949 crosses, resulting in 20 goals scored (2.1%). Descriptive statistics highlighted that offensive teams had more goal-scor- ing attempts when they used counter-attacks (18.6%) compared to organized (18.2%) and direct (10.9%) attacks. A greater number of goal-scoring attempts were observed when teams used out-swinging crosses (17.4%) as opposed to in-swinging (15%) and straight (13.5%) crosses. There was a significant (p < 0.05) association between the type of attack and match status. Winning teams preferred to adopt a counter-attacking style of play; losing teams used more direct attacking strategies, and drawing teams utilized more organized attacks. Losing teams took the highest number of crosses from Zones 1 (61.1%) and 2 (56.7%) compared to other zones. These findings provide practical implications for football coaches to tailor match tactics to replicate crossing scenarios at international competitions.","PeriodicalId":18942,"journal":{"name":"Montenegrin Journal of Sports Science and Medicine","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78422585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We used measures of 464 performances of professional soccer athletes during the National Tournament (NT=265), State Tournament (ST=89), National Cup (NC=44), and the International Tournament (IT=66). The performance analysis included the assessment of Total (meters) and Relative (meters/minutes) distances; running (>14km/h), and sprinting (>18km/h) distance; the number of sprints (>18km/h and >24km/h); accelerations (above three m/s2), deceleration (less than three m/s2) and jumps (>30 cm); Total and Relative load – per minute. There were differences (p<0.05) in terms of relative distance between NT and ST (102.2 ±9.5 vs. 98.1± 10.3) and between ST and NC (98.1± 10.3 vs. 103.4 ±9.6). In sprints >18km/h NT differed from ST (60.4 ±5.9 vs 52.7 ±19.9). In sprints >24km/h differences could be found between NT and ST (10.7 ±5.9 vs 8.7 ±5.4). In Total Load NT differed with respect to ST (908.6 ±141.5 vs. 852.7 ±138.5) In Relative Load differences were reported between NT and ST (10 ±1.2 vs. 9.3 ±1.4) and IT (10 ±1.2 vs. 9.4 ±1.4), and between ST and NC (9.3 ±1.4 vs. 10.0 ±1.4). Finally, concerning deceleration, NT differed when compared to ST (36.1 ±9.9 vs. 32 ±11) as well as ST differed from IT (32 ±11 vs. 37.5 ±9.7).

Seventeen physically active men performed two fatigue protocols (low volume and high volume) composed of continuous vertical jumps on separate weeks. Jump height, vertical stiffness, and intralimb coordination were measured during countermovement vertical jumps prior to and immediately following the fatigue protocols. The jumps were performed on a force plate and filmed with high-speed cameras. The continuous relative phase was calculated as a measure of intralimb coordination. Mixed-model ANOVA was used to compare the variables between conditions and times. The fatigue index was greater in the high-volume protocol (27±12%) than in the low-volume protocol (16±7%). Jump height decreased (p≤0.01) after the high-volume protocol. Vertical stiffness decreased (p=0.05), and the continuous relative phase of thigh-shank coupling in the ascent phase of countermovement jumps increased (p=0.04) after both proto- cols. In conclusion, jump performance was only affected by higher fatigue indexes, while vertical stiffness and intralimb coordination were affected similarly irrespective of the fatigue levels.","PeriodicalId":18942,"journal":{"name":"Montenegrin Journal of Sports Science and Medicine","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85250059","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ten professional bas- ketball players were monitored during 11 matches using a local positioning system. Peak physical demands were measured via total distance, distance >18 and >21 km·h -1 , number of sprints >18 and >21 km·h -1 , and number of accelerations and decelerations >2 and >3 m∙s -2 captured over 30, 60, 120, 180, and 300-s rolling averages. Linear mixed models and effect sizes (ES) were used to compare MDS encountered between game quarters and playing positions. Between Quarters 1 and 2, there was a reduction in the total distance (ES = 0.64-1.39) for all playing groups along with a reduction in distance >21 km·h -1 in centres (ES = 0.77-0.81) and a reduction in accelerations and decelerations >2 m∙s -2 in guards (ES = 0.66-0.78) across longer sample periods (180-300-s). Between Quarters 1 and 4, reductions in the total distance were evident for forwards and centres (ES = 0.64-0.91) as well as distance and sprints >21 km·h -1 in centres (ES = 0.64-0.97). Regarding positional differences, guards and forwards covered a higher total distance than centres across most quarters and sample periods (ES = 0.22-1.44). Our data suggest a decrease in MDS with game progression in basketball. In addition, MDS appear to be duration-specific and posi- tion-dependent in basketball. Therefore, practitioners should consider these differences in MDS based on game quarters and positional demands to optimise individual and team performance.","PeriodicalId":18942,"journal":{"name":"Montenegrin Journal of Sports Science and Medicine","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91050641","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Preschool children (N=1625) and their parents from different parts of Croatia, from urban and rural settlements, participated in this cross-sectional, population-based study. Parents completed the Netherlands Physical Activity Questionnaire (NPAQ), a measure of physical activity and sedentary behaviour in children. The main results of this study show differences in physical activity and sedentary behaviour in preschool children living in four geographical regions in Croatia (F=4.45; p<0.01). The least physically active are children from a continental area that gravitates to the capital city, while the most active are children from a southern coastal region. Sedentary behaviour is the greatest in the rural eastern Croatian continental region. Higher physical activity and lower sedentary activities in young children living in coastal compared to continen- tal regions show possible specific advantages of Mediterranean climate in general. The practical importance of information obtained in this study is a need for a specific intervention strategy for improving physical activity in continental preschool institutions.","PeriodicalId":18942,"journal":{"name":"Montenegrin Journal of Sports Science and Medicine","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73913929","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study included elite sport managers (N=118), from four team sports (football, basketball, handball, and volleyball), who participated in the highest rank of national competition in Serbia. The organizational learning culture was measured with attitudes of respondents about the organizational learning culture at individual, team or group level, and organization as dichotomous variables, while leadership styles used the MLQ self-assessment questionnaire. The climate for innovation scale was measured with scales for assessing organizational support for creativity, maladaptation, support for innovation, and resource supply. The presence/absence of components of the different marketing mix aspects was measured as a four-dimensional variable for evaluation marketing concept. The results supported the mediation and path models. Direct effect to variable marketing concept is noticed only in the organizational learning culture, while climate for innovations and leadership style did not have a direct effect on the marketing concept. Indirect effects revealed that the status of the sports branch, the market position of each club in its sport competitive results, and the education background of managers' impact marketing concept in team sports in Serbia.

This study aimed to examine the loading profiles of youth athletes during the hang power clean to determine optimal loading parameters for force, power, rate of force development, and barbell velocity. Sixteen male youth athletes (Age: 16.94 ± 0.97 years; Height: 180.08 ± 8.14 cm; Body mass: 81.06 ± 15.04 kg; Hang Clean 1RM 70.17 ± 14.41 kg) performed three repetitions of the hang power clean at 10% intervals ranging from 30-90% of their one-repetition maximum (1RM). One-way repeated measures ANONAs revealed that external load had a significant effect on the peak and average of all variables examined (p < 0.05). Most notably, peak power was maximized at 70% 1RM which was not significantly different 60-90% 1RM. Peak rate of force development was maximized at 90% 1RM, though it was not significantly greater than 50-90%1RM. Conversely peak barbell velocity was maximized at 30% 1RM which was significantly greater than 50-90% 1RM. While the results for power are similar to that of older, stronger athletes, the youth population in this study maximized barbell velocity and rate of force development at different external loads compared to more developed athletes. These results seem to suggest that youth athletes need to achieve a higher level of strength before they are capable of training with high relative external loads while maintaining high barbell velocities.","PeriodicalId":18942,"journal":{"name":"Montenegrin Journal of Sports Science and Medicine","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74584906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The test variables were best sprint time, mean sprint time, and the fatigue index. The best sprint time and mean sprint time results varied according to competition level (p˂0,05) but the fatigue index did not differentiate according to competition level (p˃0,05). It is also determined that at a high competition level players have revealed better-repeated sprint performance. When examined the data in terms of game position, best sprint time and mean time values have varied (p˂0,05) but the fatigue index did not have significant differences (p˃0,05). Considering the data according to game positions, forwards, full-backs and wingers showed higher performance than central midfielders, central defenders, and goalkeepers.
